Operating a driver in an open baffle will cause front-to-back sound wave cancellation, aka the acoustical short circuit. In addition to this, a plane board baffle offers zero air load to the drivers cone. This is not good. That's why it sounded like ...

[quote user="Romy the Cat"]The last month during the Munich show some folks from Ascendo
Audio 50" showed a new 50” subwoofer.

I am not wild about what I saw, it was WAY undersized enclosure

[quote user="noviygera"]There seems to be a lack of useful feedback on the actual sound quality of these oddball, relatively rare TAD mids. So I think it would be helpful to share some basic observations I gather after listening to them for a couple ...

[quote user="Romy the Cat"]fiogf49gjkf0dWell, that is kind of the end of the little midbass era. As
we begin to prepare the moving in a month I removed the Vitavox driver from
Midbass horns. The even went unnoticed in my family but I have a lot in ...

[quote user="Paul S"]Scott, is it your specific aim to configure an enclosure to "effectively" lower driver Fs? While this, along with an exponential increase in power, is a proven strategy for generating ULF, it seems like this approach creates more...

[quote user="skushino"]ScottL,It looks like the two pics you posted are of different systems, the first being slot loaded PP, and the second (full-system) showing a "traditional" IB. You also seem to be confirming my intuitive hunch of potential sou...

[quote user="Paul S"]Thanks, Scott L. I get the math, and no doubt hearing is believing. Still, I do know for certain that "a driver" can be influenced by a defined amount of trapped air in an enclosure, at least as far as the sound that comes from ...

Hi Paul,I'm really not sure how else to explain it, but essentially it is "free air". The driver does not become influenced by a defined amount of "trapped air" in an enclosure, thus, it pretty much maintains it's free air specs. In my case, the driv...

[quote user="skushino"]Guys, my attention has been elsewhere the past couple of weeks. The catalyst for the original post was to go beyond the usual "speakers in a room" approach, and use the room itself as an integral part of the sound. IB seemed ...

Gentlemen:I assure you, Infinite Baffle bass simply has no peer. Yes, you do need specialized drivers. The Infinite baffle bass concept is so old, it's rarely even considered anymore, plus, you are indeed married to the installation....

IMO A 60Hz attempt is too low and a 120Hz attempt too high. This is a difficult task, that of properly integrating horn loaded mid-bass withD.R subs.What type and slope crossover are you using ?I'm hoping you are going active here ?How much air can ...

[quote user="Scott L"]I had to take
pause before I answered here; realizing in an almost shocking manner [that] I
don't listen to many commercial loudspeakers.
I am largely involved in the (gasp) DIY
community, where it's also very often done inc...

[quote user="ArmAlex"]Dear Romy,Most of audiophiles listen to ported bass so there is no info left in LF to worry about.Best regards,Armen[/quote]Once again the misconception that any or all ported bass is evil and must be eliminated. This is simply ...

[quote user="Jorge"]Actually a Tapped Horn would be bigger than a sealed enclosure, here is one of my first TH tests. The sound is very different than the sound coming form a Sealed encolsure. My first impression was that the bass was gone! There...

Gentlemen:I've thought about this mid-bass challenge for quite some time. I have tried many approaches.For the sake of my example, let's assume mid-bass to cover from 60-600Hz. That just happens to be the classic "decade". I have to fully agree with ...
