Thanks Paul for sharing a Chris project. I'm a speaker building enthusiast and love to see how Chris works. Would love it if he wrote a book about the subject. I'm sure there would be a ton of great ideas.
To add to another commenter here; you guys should consider collaborating with someone like Steve Meade from SMD in California, because he is among the VERY BEST in the competition car audio world, and if you want the ultimate in bass response, a well designed and set up competition car audio subwoofer system really can't be beat for overall dynamic impact and impression. Steve's shop is super state of the art too with all of his automated CNC machining abilities and such, and his finished products always look extremely professional, best I've ever seen, plus they're always extremely impressive sound wise too, not just loud and clean, but also VERY FULL range, with his designs being some of the most amazing subwoofer systems in the world, regardless of what he puts one in! (Home theater systems too!)
Chris is back !!!, you should see the huge 42 inch subwoofer!!, looks like the huge one in the movie, back to the future, the scene where Marty tries to fire up his electric guitar in doc Browns lab !!
Love to see the accordion cloth style surrounds wonder why they're not used more often for woofers. Have a pair of vintage speakers that has em, never have to replace em sure beats foam
@@CobraChampThe 18sound NTLW5000 ist a forward tecnology mit almost same Speacs als the B&C ?18SW115? I know the JBL 2269h but! In comparision i prever the 18sound Subwoofer.
i rather put two of these big woofers in same cabinet but make it sealed, dsp to make them play even to 15hz. then you get more output up high and down at the lowest. and you can put absorbing material on the inside and cross them up as high as you like. i do anything do avoid port or slave designs.
Why the heck do you want to invert the polarity? The frequency response would be in chaos with the main drivers. 🫣 I actually remembered when I invented the phase of my woofers and being so separated from each other, they actually sounded louder but at certain frequency intervals. And anything lower than 35hz was weak. It’s all in the wavelength.
@@Bassotronics I don‘t want to, I was just wondering if that would make sense here as the woofers are facing each other. So as one cone goes out, the other cone goes in… like in some subwoofers where the speakers are mounted face to fave with vents on each back.
Have you heard the Bag End subwoofers, and what are your comments about them? I have a little 10" unit and it's surprising how it blends and sounds like headphone-quality bass.
Seeing those woofers getting screwed in without a finger around the bit gave me anxiety. You only need to see the bit slip and put a nice hole in the speaker surround once! haha Ok, so are those woofers slotting in below the floor stands? I'm curious about the frequencies.
This is just a one-off project for the studio. It’s not hard to beat rythmik or hsu, only “for the price”, as rythmik operates on a lower profit margin than most and keeps their overhead low. We will be offering subwoofers but expect (at least initially) more premium performance and pricing. I think that the perlisten subs are good for high performance (and Dan there was involved in the monoprice THX stuff). However, we won’t be doing the dual driver push pull arrangement with the butt end of the driver sticking out the bottom of the enclosure). Yes, this lowers distortion but I’d rather use single higher end drivers and make something more compact/attractive.
@@cbrunhaver Wow Chris is in the comments section! Howdy PS audio team :D Will you guys still be doing a Servosub, a few year back Paul said you guys would be using one for a future product. or maybe a Rythmik Collab?
You can use just about any amplifier to drive one of those subs. You can tell by the size of the magnet and voice coil. They are low excursion subwoofers they are not going to be power hungry. Controls are mounted on the outside of the cabinet for tweaking.
Great question! I see they showed the nasty curve without any fine tuning (bravo) but they didn't describe what they are doing in the final setup. I'll bet the FR30's are operating full range, unfiltered. Maybe Chris can chime in on this fine point.
Firstly I love ps audio and via Paul's internet series I've learned a lot of things that we take care to notice when we're (sbitav) setting up speakers for clients. But this sub confusion and obsession is very odd to me. I can't help think that those monstrosities could only work in massive rooms set up as a cinema or a nightclub - the amount of space, floor suspension and isolation, room correction and treatment required and then the difficulty crossing them over or configuring the rest of speakers and equipment - and using them with high end floorstanders (I'm not sure if that's the intention, please tell me no?) would be quite strange because as other posters are commenting what's the point of the frequency response on the floorstanders if you're not recommending ever using it for high end playback and desperately bypassing it all the time. Edit: just re watched - i don't get how such a brilliant company as ps audio have come to the conclusion to use floorstanders with gigantic subs to mix music - it may be full range but it'll also disjointed and surely very coloured? Also what recording frequencies were captured? Anything that requires those subs? And doesn't cabinet design matter for the overall bass quality as opposed to simple frequency response. Quite confused at how sticking some gigantic woofers in a homemade rectangular cabinet is the key to next level bass. But there you go.
He said they're using them for mixing, not playback. But for playback, the appeal of large subs like this is that they effortlessly make the bass you want, rather than having to crank up small subs. It's easier to take away bass than to add it.
@@stonecoldcustoms mixing is what i said (second paragraph) but playback is required for mixing, so there's that. With this set up you i don't you can simply turn up the volume on the subs/system and get 'effortless bass'. Far from it, in fact you'd likely need a tonne of other equipment in the signal path and obviously a quite advanced configuration. This makes no sense to me, those subs with those floorstanders in a mixing studio?? Just very odd. I'd use the floorstanders for high quality music enjoyment and playback and forget the subs For mixing I'd have very quality monitors paired with really capable subs.
I have two 10" subwoofers that can hit 31hz, i'm really tempted to buy a 15" REL as a center channel to hit 21hz... but alas a 15" subwoofer wont fit under my computer desk with enough room for my legs. I think i may just build a rotary subwoofer in my ceiling.
I see them struggling with a big heavy square box and I’m glad I discovered tubes which are lightweight and rigid and “no” standing waves. I’m talking mostly here in terms of car audio where we are putting lots of weight in a mobile vehicle. Think carbon nanotubes; The round structure is almost indestructible. If I ever make a speaker enclosure company, it would be all tubes. With square boxes you need thick panels, and bracing which can add unnecessary weight when a tube can be made much lighter and simpler and can be just as strong. Even if the tube walls are as thin as iphone, try to stretch and compress the wall. It’s almost impossible due to the nature of the round shape. I tell this to many people and they don’t seem to understand. They are stuck on the box mentality when tubes have many more advantages.
That sub is not designed for RAP or Hip Hop music. If you tried playing RAP music with that sub you would be very disappointed. Not for home theater either. That is a musical bass subwoofer. For rock, Jazz, Blues, Symphony, etc. etc. it’s a low excursion subwoofer. I have one of those type from JLAUDIO I bought years ago. It’s a low excursion 8 inch sub in a rectangular 3/4 inch wood ported box that has custom designed wood baffle inside the box. The box is pretty big and long in length. It’s not designed for RAP or Hip Hop. It’s for rock, blues, Jazz, orchestras, symphony etc. it hits the bass hard and shuts off without hardly any excursion movement. Yes it moves a lot of air pressure from that 8 inch sub with those bass hits.
A good sub won’t care what signal you are sending it. It will just play it the way that the artist intended it to be played. No different than any other speaker.
Sorry, that was meant for @ David From America. I’ve had a number of musical subs in my systems over the years and I have pretty diverse musical tastes. They all sounded great regardless of the genre. The sun doesn’t know if it’s being fed hip hop or blues.
@@Roof_Pizza I'm not knocking it but I do think this is the first time I've watched one of Paul's videos and thought... "Hey... I can build that." Of course when I'm done I will have cut so many corners it'll be a $100 woofer and an amp scavenged from a craigslist sub. haha
@@fallrecords Well, they're deffo going for 'a thing' as so many drivers out there are certainly built to a higher spec. Something like a 10 year old JL Audio 13w7 AW still goes for $1800 but coaxing out more below ~15 hz might've been the deciding factor.
Naw, I doubt it. These look to be passive (they don't have their own amp and DSP electronics onboard) and so with Chris using REW, they must intend to use DSP to smooth out those room gremlins shown which would require it's own amp and DSP equipment. Thus my guess, is that they are using a line level input. It sounds like you're thinking of REL's recommendation, which advocates using the high level input.

Yes indeed. Steve Meade from SMD is (arguably) one of the very best in the competition car audio world, and he is getting pretty good at home theater stuff too in recent years, with many of his designs being pretty much "mind blowing" impressive, AND really good looking and seemingly very well built too! His shop has so much state of the art equipment to make his CNC machining and cabinetry work among the very best I've ever seen anywhere. I have been following his channel for many years also, and even though he does come across as somewhat "egotistical" sometimes, he definitely DOES produce some top notch sound systems in anything he puts one in! I would say that I respect his work overall. Maybe if Paul or Chris here at PS Audio could/would collaborate with him, (or someone very similar, IF there's anyone like that in Colorado where they are?), then they could REALLY produce an absolutely amazing subwoofer system for their studio AND even their listening rooms, not only in sound quality, but super great looking and extremely well finished too! We'll just have to see how it all turns out I guess. In any case, I'm sure it will be VERY impressive, whatever they decide to end up ultimately doing, because Chris Brunhaver definitely knows his stuff when it comes to speakers, so he's not gonna let the final resulting sound system there be anything less than amazing!
@CHRIS LJ it's kind of crazy but we get mostly Californians and Texans moving here. The interaction between those two camps is pretty entertaining honestly lol.
Is it only me or this video totally shattered the high end image of this company? On the one hand there are ultra expensive components and esoteric audiophile image but on the other hand they felt no problem with adding to the system ordinary garage made box with off the shelf speaker and plate amp hastily put together. What a branding disaster.
Stupidly high excursion is never a good substiture for large boxes like this combined with large drivers, it keeps distortion very low. The trend of small boxes an large excursion is not a good one, the old Rel subwoofers like the Stadium are far better.
I respectfully disagree. A larger driver has poorer transient responses and a higher dampening factor which makes the driver slower in responding to variations in the signal which causes distortion.
@@JonAnderhub To get low frequency flatness you need to shift large quantities of air, my argument is in order to shift that air, its better to use larger diameter cones in large boxes than to use small diameter drivers with very large excursion. The reason large excursion is a bad idea, is because the complience of the surround and spider is very non-linear and the former-magnet never has perfect field linearity, so its very difficult to create a linear piston over large excursions. Now you may be right with certain exotic drivers with advanced techniques, but most drivers built for high excurion have imo high distortion. Another good reason for low excursion is you can often hear the 'chuffing noise' on higher excursions, thanks for your reply.
Most people won’t understand what you are trying to convey here. I have a crazy Home Theater undergoing a years long overhaul which uses both High Xmax sub drivers in large sealed enclosures for the -30Hz range (ten 21” drivers and six 24” drivers) which will run off of the LFE from the Trinnov Altitude32. Then I am using custom 18” pro drivers for each channel (20+ channels). The front LCRs each get four of the 18s then as channel placement gets closer to the seats the number of 18s per channel can decrease down to 1 or 2 per surround/overhead/Atmos/etc….
@@alford35 You must have a very large room), I have two subs barely off minimum tuned at 30Hz, not exactly ideal as one is a Rel Storm and the other a 100w BK, the later is a high excursion unit fairly highly reviewed yet to my ears sounds inferior to the larger Storm. I have built subs in the past, nothing with 24" drivers though, hope your home is of good construction with all that air being shifted). What is the xmas of those drivers?
@@JonAnderhub One point, the transient response is related to the Q factor, small boxes inherently have inferior transient response with Q's exceeding say 1, but you tune to optimal design(which is usually a large closed box say 100L for many drivers) and you can get the perfect transient Q=0.7, or another way to see it, less travel means generally faster response.
well to be fair, excursion is distortion. excursion require design compromises and the output itself at high excursion causes issues. its better just to have many woofers than a few long throw.
Thanks Paul for sharing a Chris project. I'm a speaker building enthusiast and love to see how Chris works. Would love it if he wrote a book about the subject. I'm sure there would be a ton of great ideas.

Both are the same.

Now you may be right with certain exotic drivers with advanced techniques, but most drivers built for high excurion have imo high distortion. Another good reason for low excursion is you can often hear the 'chuffing noise' on higher excursions, thanks for your reply.
Most people won’t understand what you are trying to convey here. I have a crazy Home Theater undergoing a years long overhaul which uses both High Xmax sub drivers in large sealed enclosures for the -30Hz range (ten 21” drivers and six 24” drivers) which will run off of the LFE from the Trinnov Altitude32.
Then I am using custom 18” pro drivers for each channel (20+ channels). The front LCRs each get four of the 18s then as channel placement gets closer to the seats the number of 18s per channel can decrease down to 1 or 2 per surround/overhead/Atmos/etc….
@@alford35 You must have a very large room), I have two subs barely off minimum tuned at 30Hz, not exactly ideal as one is a Rel Storm and the other a 100w BK, the later is a high excursion unit fairly highly reviewed yet to my ears sounds inferior to the larger Storm. I have built subs in the past, nothing with 24" drivers though, hope your home is of good construction with all that air being shifted).
What is the xmas of those drivers?
@@JonAnderhub One point, the transient response is related to the Q factor, small boxes inherently have inferior transient response with Q's exceeding say 1, but you tune to optimal design(which is usually a large closed box say 100L for many drivers) and you can get the perfect transient Q=0.7, or another way to see it, less travel means generally faster response.
1.5 inch xmax peak to peak is moderate , not impressed
well to be fair, excursion is distortion. excursion require design compromises and the output itself at high excursion causes issues.
its better just to have many woofers than a few long throw.
I immediately knew they were lazy and lame when I heard "we should make a warehouse guy do it". Respect loss big boy.
...I wanna hear it.
Then make an appointment and go to Colorado. I see no way to demonstrate it otherwise (especially not via a YT video).
@@Fastvoice Ok then.
Hope you don’t get someone’s foot in the woofer cones
