2" sounds good for a two way speaker with a low crossover point for great integration between woofer and "tweeter". The directionality of the 2" driver up high would be good in a relatively live room
Just wondering does anyone know whether the youtubers of two channels similar to this one, Kirby Meets Audio and Impulse Audio, are okay? About eighteen months ago the Impulse Audio guy said it may be a while before he posted again because of home commitments, but Kirby Meets Audio just stopped, apparently mid project.
You didn't consider putting the 4 inch driver in a small sealed box, hit it with gobbs of power and take full advantage of all that excursion?..why does everything have to be ported?
This really was designed for a ported box. It really doesn't perform well in a sealed box. This particular driver, even with the excursion will only have an F3 of 93hz. You would think that with this excursion you could DSP it using something like a linkwitz transform, but even in a small box you run out of excursion by 63hz before DSP. meaning there is no meaningful low end you could dsp out of it. You could keep it sealed, but I don't see any reason why you would. Kartesian even has two designs for it, one ported and one using passive radiators.
@@Toid well then...carry on..but if it's designed as a "sub" woofer..but sux as a subwoofer..put it in a sealed box and cross it over at 100hz or above?..you said it played well in the upper regions?..I'm not saying...I'm just saying
I have a thought on this... even Bose calls their 'subwoofer' a 'Bass Module' at least for the 2.1 Acoustamass system they sold for years and years. I'm pretty sure they DSP the Cr*p out of their bass module too, even though it's vented. I'd think of this subwoofer driver as something like that. It's kind of understood that such a small bass speaker isn't going to reach the 20-30 Hz range with any audibility to speak of. But it can produce enough real-world bass to seem 'satisfying' at low to low/medium volumes, and that's all many people need. That's perfect for a small room setup or computer desk... heck even a UA-cam editing setup. (My editing setup uses a set of Jeff Bagby's Quark speakers powered by a small 2.1 amp with a single ND105 vented as the subwoofer. That thing is only 4" and there is just one!) 50 Hz represents real bass in my opinion, and there is some output below that, just not a bunch.. No, not traditional 'subwoofer' territory, you're right, but I think we just need to interpret these things in light of what they are... really cool super-small bass drivers. Just my un-asked for opinion. :) Anyway, I really enjoyed both the satellite and subwoofer videos a lot. That's a fun 'little' project that you could hide almost anywhere. Bose hasn't sold Gajillions of those 2.1 setups for no reason.
@@zarboaudioprojects1430 actually bose woofers dont even go below 80 hz, they use harmonics to trick the ear into hearing base that is not even being pushed through the driver. if you ever hear an example the climbing staircase audio is an example of using harmonics, our ears hear it going up and up and up but its the same 5(?) notes in the sequence over and over. thats what bose did and its basically a fraudulent way to market a product IMO
I agree that 50Hz F3 is, by definition, *not* a subwoofer. To quote Robert Harley's The Complete Guide to High-End Audio, "But subwoofer actually means 'below the woofer,' and the term should be reserved for those products that extend bass response to below 20Hz." Personally, I consider 90% of what we call subwoofers to be "super woofers" that simply enhance bass response without actually reaching 20Hz or below, but I'm okay with calling an F3 or 20-30Hz a "subwoofer" as so many people already do and that's already below what most woofers produce. It's simply unacceptable to raise that figure to 50Hz, though, as normal woofers will, or should, go that low. Some of the first subwoofers were Cerwin Vega monsters set up in select theaters in 1975 to produce sound effects for the movie "Earthquake". These were true subwoofers that could supposedly extend to 16Hz, which is indeed subsonic. Since then, the term "subwoofer" has been stretched by marketing departments to the point where it's nearly meaningless. This is evidenced by the reality that even many audiophiles and speaker designers now consider speakers to be excellent "subwoofers" when they have an F3 of 35-40Hz. No, those are simply good woofers; they aren't subwoofers at all.
I agree with you. Although I do feel like anything below a six and a half inch, you need to temper your expectations. The lowest driver that I can think of without DSP that can get anywhere near there is the w5 by Tang Band and the new epique line (around mid 30's). I feel like there needs to be a classification for mini subwoofers that are designed for desktop use.

TBH cartesian will never be popular in the USA with so many great speaker deals. Watching part express and almost want to buy everything compared with Euro prices. Cartesian drivers VERY strange. They position themselves as HiEnd but measure not so. Love their looks. Not seeing anyone show a good speaker example they perform BETTER another trusty brands.
there was one of their glass fiber cone drivers and a tweeter but i cant remember who, but there are also lots of forums posting data that contradicts their claims, and heavily
These drivers in the next DINAS speaker?
Actually I have a passive version of the Dinas coming out very soon.
@@Toid AWESOME! Can't wait. Pair them with an Aiyima A07 amp and I bet the audio reproduction would so pleasing.
You channel really kicks ass. Never thought about replicating a Bose cube system.
Appreciate it!
I have a few Bose system I like them but they could have a little more high
Thank you for all your hard work! Another great video!

Seems to me like a perfect match to use those drivers and design a two way using them.
wheres the live sound check or the actual audio test??.. we wanna hear how it sounds and how d box design performs.. for movies and music..
These would probably work good in my camper.
Would a set up similar to this design make a good first time 5.1 surround sound build.
Can you provide the WinISD data for the woofer ?
The Voxel variations and Peerless 2-1/2" are looking better now. Nice cap!
I agree. And Go Pack Go!

Put rainbow dead I've been in contact with impulse audio. I'm hoping to start doing some projects with him when he gets back to it.

@@Toid That W5 is a tooth chipper! It really hammers for such a small driver.
@@brianraulerson5037 completely agree. It's really unique, which is why I love it. The exception, not the rule
Where in the USA can you buy these?
where is this USA?
@@vlatkogacesa Earth
Have you used the Dayton tcp115 drivers?
I have. They are really good for their price. But not the same quality as this 4" driver. Of course there is a major price difference.
@@Toid Hi, do you know if there is some klippel measurements of the sub120. I want to know if the 6mm xmax is 10% or more like 30% Bl loss.
@@roygriend5143 yes. It's on their website
@@Toid i only can find T & S parameters, no bl graphs etc..

@@Toid Thank you very much :)
Use as free air model. In box with NO back wall of box
Wave guide the subwoofer
Speaker test without the actual sound test
