Thank you Kelvin. Your format is absolutely fine as is. I think most of us know the songs you are referring to which helps picture the speakers or amps strengths and weaknesses. I have a Yamaha cr 2020 powering a pair of Celestion Ditton 44. Would love to hear you review a pair of 44’s to 66’s The speakers I found in Quebec 350 miles from my home. It makes me smile when in other videos you mention having to travel a long way to get something and the you say 40 miles. Great work mate look forward to your work and the lava lamp!!
And here we are, with one model of speakers I have been wanting to get for sooo long....good lord, and I have wasted a lot of opportunities to get them.... Instant like!
I bought a pair of these 6 weeks ago for $100 AUD (Australian) - I then refoamed them which cost $28 for a full set with glue. And I can't get over the great sound they have, its hard to explain the clarity these speakers have a bit like wearing headphones - I have them set up on each side of a large computer monitor. They do serve well with an added sub but most speakers do. One of the most enjoyable speakers I have owned thus far. cheers
Hi Symon - I just bought a pair of the CX-100's which are in need of a refoam would you mind sharing info about how and where you found the materials to refoam them? I notice we have Steve Edmunds as a mutual friend.
Hello Kelvin I like you comparing a set of songs that we are also familiar with takes it out of the Abstract Also like you videos generally , look forward to each new post
I have a nice little mod for these. Replace the 6.8uf electrolytic capacitor with paralleled polypropylene film caps to make around 6.2uf and add 1 ohm series resistor (They sound a bit too bright just swapping electrolytic for film). Much better transparency and detail for the top end which sounds great with those speedy little woofers.
An excellent way of discribing how a speaker sounds. If the music is known to you, it really gives you an idea of how it will sound in your own application. I have recently got my hands on a pair that I will complement with a subwoofer and I believe that I will thouroughly enjoy my new setup of speakers.
Great review I thought you put the speakers into good context and emphasized positives and negatives. I think for the money these are one of the better bargains to be had which is also a point that came through in your video. Thanks for the video!
I once thought B&O was just expensive eye candy until I found a pair of used unusual looking speakers by them in a thrift store a very long time ago. I can't remember the model but they were missing some kind of metal stands to connect them to. They weren't big, but I was impressed by the sound from what seemed just like a cheap black plastic cabinet and a single driver. I couldn't believe it could produce some of the low end bass sounds like it did. Overall though, it still wasn't impressive enough to keep them, but I gained some respect for their engineering.
Both the CX100 and the CX50 are great speakers. For my home cinema/music system I'm using two Beovox S55 as front speakers with one CX100 as center and four CX50's as surround speakers. The great benefit from this is that all these speakers were designed to work together, and the result is better than great!
Hi, I followed your advice in these CX100. I am a pensioner, on a budget, but love, as well as understand, good sound quality. I bought a par, secondhanded, renovated, as you explained. Wow, how right you are. These Beovox are really good sounding. Incredible for the price, or, I’m just old, and don’t really know anything. But, I think not! Thanks, for making me happy ;-)
Another aluminium-cased speaker that's underrated (in my humble opinion) is the Technics SB-F1. As an added bonus, they don't seem to suffer from foam rot!
I’m starting to use the same songs you are to listen for those details you describe. I for one, really like that you use that method. Thanks for all the great knowledge.
Comparing the same songs is a great way to review equipment. As soon as I get my hand on a new bit of vintage kit I'll listen to a familiar song. How about some turntables next.
I heard this review of Beovox CX100 and found it to be very convincing. In fact, so much that I went on the hunt, found some that had the explained foam rot issue, cheap. I bough them and had them fix (not so cheap), and now I am very very very happy, with one on each side of my big monitor on the wall using them with my computer, USB DAC sound card and a Class-D amp. The sound is unbelievably good, so much that I am maybe going to move them to the living room. Thank you, Kelvin, you are great.
Yes I love when you mention songs,I play them ,just do different selection if you can as per video,and you are very entertaining and informing keep it up , I love retro and some new tec audio ,cheers mate
hi Kelvin, really good roundup there. I've scooped a few pairs of these and refoamed and recapped a couple pairs, and looking to put binding posts on a pair maybe.
I've recently refoamed my CX100s and totally agree with your review playing through a B&O Beocenter 9000. I think the hard to place sensation of the speakers comes from the "woofers" not being aligned with each other. As you say they are very focussed on the vocal spectrum which has it benefits, not disturbing other rooms or neighbours with punchy bass for example. They are fundamentally not suited to rock music, it just doesn't sound right and that is quite a shortcoming. Of the tracks I've played on my CX100s, Hymn To The Fallen from the Saving Private Ryan soundtrack showcases the CX100s to their best ability. Time has moved on B&O's later active speakers, and later again with the acoustic lenses are fundamentally better balanced for different types of music.
Good comments thank you I’m just thinking maybe those small cones can’t deal with the busyness or multiple sounds of rock music they need more simple music
Just found my old CX100s in some storage box today. When I removed the cover I realized the surround foam is completely rotten. I had them stored carefully and they look like brand new otherwise. I believe these will do excellent with a subwoofer.
Fantastic. I so much agree that these CX100 are really really high value for money - i.e. if they are refurbished as foam replacement. I did just that by having a professional do it. They sound great.
Great review, was thinking of buying a second hand beocenter 9500/9300 with probably these speakers. Now I know they are great. What about a review of the Ban and Olufsen famous Penta speakers these days ? are they worth it ?
I got the smaller CX40 with one woofer and one tweeter only; but have to refoam them. I recognize what you describe about space in the sound and the clarity even with low volume. (at higher volume you can hear they need new foam ;)). Thanks so much for paying attention to these retro speakers! 😊
@@stereoreviewx much appreciated. I bought a repair set but I postpone refoaming cause it’s such a precise work.. good advice to replace the woofer, so complete with ‘fresh’ foam. On the Catawiki auction site people offer more than 120 euro for a refoamed set of these cx100 😮crazy world. Cheers and till your next video!!
Youre doing good like you do it now. So we have a idea how the sound of the speakers is. I can buy now a pair refomed for 140 euro, and didnt know what to do. Now afther youre vid I know it. I'm not gonna buy them. So thanks for helping me to decide. Greatings from belgium !
Great review! I watched your video a few times after seeing a pair of these for sale. Your video convinced me that it would be a great purchase. I inherited a clean pair of Beovox 2600 speakers a few years ago. Amazing sound, and looking forward to refoaming these CX-100's. One question, the mounting bracket looks a little crazy, how does it mount to the speaker so I can eventually grab a pair of brackets so I can mount them on the wall? Thanks again!
Nice review, credible, believable. No, you don’t really need to speak about specific songs. Most people don’t know them anyway, or don’t like them. But do state you opinion about the various types of sound - base, vocal, high, etc.
Just got a hold of this and the Beocenter 1400 for 500 danish kronor thats a little less then 80 pounds...and i do love B&O,those are legendary as speakers! Its true that the base is not there but they are made for a clear sound and that they deliver with exellence if in ok state! Use them together with the darker Bose Music Monitor II model 301 and you will find a sound so dep also clear that you dont need anything else! Thanks for the film you made (Y)
Yes for £80 you could’ve bought some mediocre cables😃 Just to say Yes those b an o speakers I have on the wall which I find superior you may have that I don’t know. Very annoying it’s hard to DIY that I landed at buying the fittings on eBay for nearly £50 ouch now I discovered someone is making cheaper versions I think £25
I've had a pair for a good while now. Wall mounted with the specific brackets you can get. I have them either side on my iMac screen as monitors in a home studio. They point past my ears but sound better slightly off axis. I also have the Cona sub and that works a treat. I should get a pair of these but I dont have the room! I use them with an old Linn power amp or a pair of bridged smaller Amcrom power amp. Be a snob if you want and leave it to us to enjoy. B&O have the money and facilities to develop good speaker. (I also use Linn Isobariks, Epos ES14s and a few more.....including Philips MFBs)
I would like to add that the cross over filter divedes the signal i three different sectors, below 140 Hz for the first of the 4 inch speakers, 140 to 2500 Hz for the second 4 inch speaker and above 2500 Hz for the tweeter.
Firstly, thank you for making great review videos, I really enjoy them. Secondly, I recently purchased the smaller CX50 just because they looked cool and were made from aluminium. I immediately fell in love with the sound! I have them paired with a small subwoofer and the sound is absolutely fantastic!! I am now on the lookout for the CX100, but they are quite rare in Australia, so I'm not holding my breath. Thank you again for the great reviews!
I have a pair of CX100 in white - matched to a Beocenter 9000. The four foams where £6.64, with £1.75 for the contact cement. There are a number of UA-cam videos showing you how to fit the foams. Some on sale have been re-spayed, others have a new vinyl covering. Going rate £100-375. The CX100 and CX50 can be updated to having a built in streamer with wi-fi and Bluetooth built in using a Raspberry Pi (4B £70) and a Beocreate 4 channel amplifier (£139 ) {all in with fittings and cables under £270}. The CX50 (only one bass cone) can be wired up in stereo with the second speaker only needing an XLR socket fitted. The CL100 has both woofer output used and one tweeter. The software comes with a configuration for both CX50 and CX100. The quality is far higher than a modern wireless/Bluetooth speaker for much more than this outlay. A wireless/Bluetooth input and a power amplifier of 40-60Watts works as well; streaming from a mobile phone; something like the Nobsound between £50-100.
Yes I did re-phone those speakers I don’t know if I say that in the video also the speakers seem to have come down in price I think they’re great I’m playing them right now and I really enjoyed them
You could make some brackets out of three quarters of an inch of plywood two holes drilled near the top one at the bottom in a triangle, a carriage bolt and nut recessed at the back with a big washer, and then stick a mouse mat on the back with the non foam side against the wall they're not that heavy how much does one weight? what size is the Keyhole hole size knowing what carriage Bolt to use. I would have thought the driver's would be seas they generally used to use seas drivers. Did you replace the foam with foam foam is better than rubber it's less mass in total on the driver. You should try DSP them we'll get your bass, something like rew what is free or dirac live or Mini DSP, ideally having joined terminals on the back would be good these speakers have fantastic potential I will have to try and get a pair let me know if you see any cheap If you measured the EQ of the LS5 in REW you can reproduce this in the the bang and Olufsen and give you the same signature as the LS5 and probably be better Go with the songs it is different people can have a great understanding I think knowing the songs what you're saying
Another excellent review. I like my own set very much. I often wonder if it is possible to match them with a used or new subwoofer (with a modest footprint) … B&O’s dedicated floor model is impractical for me.
Thank you for this great review ! You use the right words to describe the sound 👍👌 Question - what subwoofer would you recommend for these Beovox ? Did you try one connecting with these ? Wood love your advice 😉
Well honestly I don’t use subwoofers but I know lots of people do and I’m sure it would benefit Because the speakers are so good in the mid range and no speaker can do everything personally I’m not a fan of subwoofers I like to keep the stereo image alive K
These are mainly bookshelf speakers that probably would be better working with a good subwoofer and some tone control to adjust the mids and highs to work with it.
Great channel with lots of useful tips and information! I just got a pair of cx100, I am really imperessed by their performance, a true "hidden gem". Can you suggest what vintage (or modern)amp I should be looking for to bring the very best out of them, which of your amps, based on your experience do you think are the "best match" ? Best regards
Hi Bjorn yeah I’m glad you like the speakers they have got some great qualities amplifier wise I can’t say I have a big obvious choice In the vintage world I’m such a fan of early Sansui I mean I don’t think there is a quality you need to look for in the amplifier to counteract any problems with those speakers so that it just needs to be a good amp For modern amps you won’t go wrong with naim . Personally I’d say 50 what’s the channel is fine over 100 will choke these little speakers Cheers K
There's a B&O passive subwoofer called Cona that's meant to go with the beovox bookshelf speakers, I've got c40s and have been told by two people the Cona makes them sound amazing but the Cona seems impossible to find, I don't even see any history of them on ebay
Hi, Just re-foamed some CX100. The HF are Belgian and the cones Japanese I believe (Minebea maybe). Almost identical apart from one has a vented pole piece and the other not and wired differently in crossover. So I guessed they are Mid and Bass. Soundwise I concur with the vocals and upper/mid clarity. Heard stuff unheard. Bass ahem but tuneful. Tweeter diffraction grating a bit weird moving my head side to side. Refoaming I decided to use shims and made a bit of a pigs ear cutting out dust caps but they are defo well centered. I had done bigger Vifa drivers without shims and felt meh if I pressed one side of the cone it may scuff a bit and the other side not. The glue on the B&O is awful. Got some CX75 to do next.
I want to buy this as rear speakers for my bang and olufsen 5.1 system, but the lack of bass is a concern. I don't want it sounding tinny. Also you are the only person to review these speakers. Kinda strange.
Hard to know what to say here they only make okay base and need to be put against the wall hooked onto the wall I mean Funny thing with the Speakers is initially I won’t impress you but I have them on right now and I don’t object to anything and I enjoy them It’s a little different to a normal big box sound but it has certain appeal
Was able to pick a set up for 80 euros that are in good condition, they only had yellow vinyl sticked all around it which i could just take off! normally they go for about 180 euros here! This was after watching after this vid about a week ago, thanks for what you are doing! Have you got any recommendations for a receiver at around 70-100 euros? Same goes for the pre-amp.
Would be good to get some new music on the comparison to understand how they sound through old amps/speakers. I,e Drum and bass, Prodigy, Nitin sawhney, etc
Hello! Great review thanks! I purchased first BO C40 which I found really nice and bright. Then I was looking at the CX100 thinking that they would be a better version of the C 40, perhaps with more base. However, They haven't delivered int he way that I imagined. I get better sound out of them at higher volume I think? Foams seem to be be OK all round but maybe they are degraded? I was just wondering if you had any insight into this perhaps?
Okay well I’ll have a go from a distance. Have you checked the tweeters are working you could do a comparison C 100 and see 40s turn the base down turn the treble up . So you’re hearing mostly the tweeter and are they sounding the same as each other or pretty similar That’s one possibility. The other thing I’m thinking is positioning if you say we are close to those small speakers and then close to the bigger ones I mean it might be you need to be further away from the bigger ones. Or even you’re so used to a bright sound the big ones seemed comparatively dull. Good luck cheers K
i just tried my cx100's... too bright, I tried to be clever and recap with a modern film cap, lucky i kept the originals and sourced some new old stock unused, will be changing them back I think! or add a resistor maybe. with low ohm drivers, the crossover caps esr is tuning the sound to help lift the lower freq i think.
Nope they did this the right way round! Think about it, if plug is pulled out and two conductors are exposed and touch metal - you get a short. Luckily B&O amps have good protection but depending on the model you may have an internal fuse blow.
Hi fi people poo poo B&o too much, they don’t understand them. The older stuff has a really nice sound. Yes maybe not up to the “I’ve spent 10k on speaker wires” brigade but a very nice easy to listen to sound that’s far better than most. And it looks beautiful. I think it gets downplayed because it’s not an ugly box with tonnes of cables. Can you get better, probably. Can you get prettier, no.
I've managed to do a refoam but the bass driver sounds blown. Could I disconnect the bass driver and safely run it with just the tweeter and mid range driver? Any suggestions?
There are two possible reasons why your speaker sound blown. 1. It came with a warped voice coil before you refoamed it, scratching the magnet. Could suggest overheating at some time by feeding to much power into the speaker. Remedy is to find a replacement speaker 2. The refoam job was not successful, the speaker cone not centered good enough when appliying the new foam= Voice coil is scraping the magnet and produces a "blown" sound. Its fixable because its only a matter of centering i again. Nothing is broken per se. I would try to remove the old (new) foam and try again. or let an experinced tech do the job. If it turns out the same there ara speaker replacements if you look around
Why nobody cares about rubbing the boxes on the table in all directions? Doesn't this scratch a little each time the bottom of the speaker? The box must be lifted each time, not twisted on a table..!!!. I have a very expensive Italian violin from 1754 that is in perfect shape and worth $0.8 million !!! That was always lifted...
they are too sharp ......... in sound ......... cheap philips metal dome tweeter........ price says nothing about musical class. I am musician, technician, have sold top hifi.. its has a budget sound. and you are deaf .
It’s not even a metal dome driver lol, and the sound is good. Obviously different from a $20.000 per speaker set but thats not the point. Take ANY passive speaker with the same size and these will outperform. They are clear and bright in vocals and create a good ‘live’ experience. Not perfect by any means but a lot of people enjoy these.

Thanks for the feedback watch out for foam rot on the CX 100 almost certainly they will need to have been re-phoned or need re-froaming. K

The CX100 and CX50 can be updated to having a built in streamer with wi-fi and Bluetooth built in using a Raspberry Pi (4B £70) and a Beocreate 4 channel amplifier (£139 ) {all in with fittings and cables under £270}. The CX50 (only one bass cone) can be wired up in stereo with the second speaker only needing an XLR socket fitted. The CL100 has both woofer output used and one tweeter. The software comes with a configuration for both CX50 and CX100. The quality is far higher than a modern wireless/Bluetooth speaker for much more than this outlay.
A wireless/Bluetooth input and a power amplifier of 40-60Watts works as well; streaming from a mobile phone; something like the Nobsound between £50-100.
Yes I did re-phone those speakers I don’t know if I say that in the video also the speakers seem to have come down in price I think they’re great I’m playing them right now and I really enjoyed them
Felicitaciones desde Argentina...su video me convencio de comprarlos....x ebay desde Londres.....muchas gracias
You could make some brackets out of three quarters of an inch of plywood two holes drilled near the top one at the bottom in a triangle, a carriage bolt and nut recessed at the back with a big washer, and then stick a mouse mat on the back with the non foam side against the wall they're not that heavy how much does one weight? what size is the Keyhole hole size knowing what carriage Bolt to use. I would have thought the driver's would be seas they generally used to use seas drivers. Did you replace the foam with foam foam is better than rubber it's less mass in total on the driver.
You should try DSP them we'll get your bass, something like rew what is free or dirac live or Mini DSP, ideally having joined terminals on the back would be good these speakers have fantastic potential I will have to try and get a pair let me know if you see any cheap
If you measured the EQ of the LS5 in REW you can reproduce this in the the bang and Olufsen and give you the same signature as the LS5 and probably be better
Go with the songs it is different people can have a great understanding I think knowing the songs what you're saying
Great work. Thank You!
Another excellent review. I like my own set very much. I often wonder if it is possible to match them with a used or new subwoofer (with a modest footprint) … B&O’s dedicated floor model is impractical for me.
I now have them with subwoofer. Even better 👍
Thank you for this great review ! You use the right words to describe the sound 👍👌
Question - what subwoofer would you recommend for these Beovox ?
Did you try one connecting with these ?
Wood love your advice 😉
Well honestly I don’t use subwoofers but I know lots of people do and I’m sure it would benefit
Because the speakers are so good in the mid range and no speaker can do everything personally I’m not a fan of subwoofers I like to keep the stereo image alive K
@@stereoreviewx A pair of subwoofers to keep the stereo.. Maybe 2 Rel Quakes :)
These are mainly bookshelf speakers that probably would be better working with a good subwoofer and some tone control to adjust the mids and highs to work with it.
Stick with the songs. Gives a good reference point. I listened to some of the tracks on my system and then I can compare and understand better
Great channel with lots of useful tips and information! I just got a pair of cx100, I am really imperessed by their performance, a true "hidden gem". Can you suggest what vintage (or modern)amp I should be looking for to bring the very best out of them, which of your amps, based on your experience do you think are the "best match" ?
Best regards
Hi Bjorn yeah I’m glad you like the speakers they have got some great qualities amplifier wise I can’t say I have a big obvious choice
In the vintage world I’m such a fan of early Sansui
I mean I don’t think there is a quality you need to look for in the amplifier to counteract any problems with those speakers so that it just needs to be a good amp
For modern amps you won’t go wrong with naim .
Personally I’d say 50 what’s the channel is fine over 100 will choke these little speakers
Cheers K
There's a B&O passive subwoofer called Cona that's meant to go with the beovox bookshelf speakers, I've got c40s and have been told by two people the Cona makes them sound amazing but the Cona seems impossible to find, I don't even see any history of them on ebay
Must say I’ve never heard of
This is great 👍😊🤩
Hi, Just re-foamed some CX100. The HF are Belgian and the cones Japanese I believe (Minebea maybe). Almost identical apart from one has a vented pole piece and the other not and wired differently in crossover. So I guessed they are Mid and Bass. Soundwise I concur with the vocals and upper/mid clarity. Heard stuff unheard. Bass ahem but tuneful. Tweeter diffraction grating a bit weird moving my head side to side. Refoaming I decided to use shims and made a bit of a pigs ear cutting out dust caps but they are defo well centered. I had done bigger Vifa drivers without shims and felt meh if I pressed one side of the cone it may scuff a bit and the other side not. The glue on the B&O is awful. Got some CX75 to do next.
I want to buy this as rear speakers for my bang and olufsen 5.1 system, but the lack of bass is a concern. I don't want it sounding tinny. Also you are the only person to review these speakers. Kinda strange.
Hard to know what to say here they only make okay base and need to be put against the wall hooked onto the wall I mean
Funny thing with the Speakers is initially I won’t impress you but I have them on right now and I don’t object to anything and I enjoy them
It’s a little different to a normal big box sound but it has certain appeal
The last thing they sound is tinny. Far superior to any normal 5.1 rears, and forget about the naff Beolab 14 surround sound setup.
I have CX50 and with the Cona subwoofer.
I once had these too, from a distant inheritance, I replaced the little woofers, they are oem, and they cost only 8 euro a piece:)
Where did you get the woofers?
Was able to pick a set up for 80 euros that are in good condition, they only had yellow vinyl sticked all around it which i could just take off! normally they go for about 180 euros here! This was after watching after this vid about a week ago,
thanks for what you are doing!
Have you got any recommendations for a receiver at around 70-100 euros?
Same goes for the pre-amp.
Would be good to get some new music on the comparison to understand how they sound through old amps/speakers. I,e Drum and bass, Prodigy, Nitin sawhney, etc
Hello! Great review thanks! I purchased first BO C40 which I found really nice and bright. Then I was looking at the CX100 thinking that they would be a better version of the C 40, perhaps with more base. However, They haven't delivered int he way that I imagined. I get better sound out of them at higher volume I think? Foams seem to be be OK all round but maybe they are degraded? I was just wondering if you had any insight into this perhaps?
Okay well I’ll have a go from a distance.
Have you checked the tweeters are working you could do a comparison C 100 and see 40s turn the base down turn the treble up .
So you’re hearing mostly the tweeter and are they sounding the same as each other or pretty similar
That’s one possibility.
The other thing I’m thinking is positioning if you say we are close to those small speakers and then close to the bigger ones I mean it might be you need to be further away from the bigger ones.
Or even you’re so used to a bright sound the big ones seemed comparatively dull.
Good luck cheers K
I just got a pair for 50 D.Kr = 5 £. :-) I live in Denmark. B&O are very cheap here. Perfect match for my summer house.
i just tried my cx100's... too bright, I tried to be clever and recap with a modern film cap, lucky i kept the originals and sourced some new old stock unused, will be changing them back I think! or add a resistor maybe. with low ohm drivers, the crossover caps esr is tuning the sound to help lift the lower freq i think.
Is the crossover 1st order ?
They are SEAS drivers from Norway....
how do they compare against B&W DM4 ?
“Songs” are helpful 👍
i don't know if you have heared a pair of mission 761's yet but how would you compare them to these cx100's? im wanting to try the missions out!
Has any one else tried playing music through a blue ray player? I tried with my nad 3020i. Sounded amazing on kef coda 9s
Please review a pair of Goodmans Double Maxims!
Nope they did this the right way round! Think about it, if plug is pulled out and two conductors are exposed and touch metal - you get a short. Luckily B&O amps have good protection but depending on the model you may have an internal fuse blow.
Interesting. Which do you prefer the cx100 or the older 3700 with the 8" bass unit?
That’s close I think I just say CX 100 K
My CX50 have a very pronounced harsh sharp treble..Kinda weird. Might try a pair of CX100..
Might just be too small to make decent bass
Hi fi people poo poo B&o too much, they don’t understand them. The older stuff has a really nice sound. Yes maybe not up to the “I’ve spent 10k on speaker wires” brigade but a very nice easy to listen to sound that’s far better than most. And it looks beautiful. I think it gets downplayed because it’s not an ugly box with tonnes of cables. Can you get better, probably. Can you get prettier, no.
Yes there is a snobbery from hi-fi people against bang and all of a sudden generally speaking some of it goes quite cheap fortunately
I like it
I've managed to do a refoam but the bass driver sounds blown. Could I disconnect the bass driver and safely run it with just the tweeter and mid range driver? Any suggestions?
I am not sure that is safe it depends how it’s wired I mean it probably is but you just won’t have any bass
There are two possible reasons why your speaker sound blown.
1. It came with a warped voice coil before you refoamed it, scratching the magnet. Could suggest overheating at some time by feeding to much power into the speaker. Remedy is to find a replacement speaker
2. The refoam job was not successful, the speaker cone not centered good enough when appliying the new foam= Voice coil is scraping the magnet and produces a "blown" sound. Its fixable because its only a matter of centering i again. Nothing is broken per se.
I would try to remove the old (new) foam and try again. or let an experinced tech do the job. If it turns out the same there ara speaker replacements if you look around
have them . philips tweeter.
Why nobody cares about rubbing the boxes on the table in all directions? Doesn't this scratch a little each time the bottom of the speaker? The box must be lifted each time, not twisted on a table..!!!. I have a very expensive Italian violin from 1754 that is in perfect shape and worth $0.8 million !!! That was always lifted...
I have them... just philips speakers inside. basic philips dome tweeter.
Yeah sure I know the Philips drivers there is something interesting about what this aluminium box can do it’s kind of unusual thanks K
they are too sharp ......... in sound ......... cheap philips metal dome tweeter........ price says nothing about musical class. I am musician, technician, have sold top hifi.. its has a budget sound. and you are deaf .
Are you sure that’s a metal dome tweeter
It’s not even a metal dome driver lol, and the sound is good. Obviously different from a $20.000 per speaker set but thats not the point. Take ANY passive speaker with the same size and these will outperform. They are clear and bright in vocals and create a good ‘live’ experience. Not perfect by any means but a lot of people enjoy these.
@@SheepyYeen it is a dome. indeed not metal (looked at it) ....... it is a philips dome.
@@stereoreviewx no sorry dome tweeter, think cloth.. but I have two of them.
