Hi Ron;) It's great to see WBF constantly expanding and all the different things they provide to all the people who view this forum. One of the questions you asked Damon about why did we have a rear firing woofer as opposed to a front firing sub? I wanted to just touch on just one of the reason as well as the ones Damon touched on. Having the sub in the rear in our opinion from both measuring and listening is far superior. It is a compromise having the sub in the front that will modulate the critical air being pushed by the upper bass and even more critical mid and treble. Not to mention you just now added another pressure source to the existing speaker which will usually reinforce and lead to more extreme dips and peaks in the room. The rear lessens this by a huge percentage and there is a lot more this than just the location of the driver. But that's all I'm going to say about it and because their are so many other facets to this it's hard to chose aspect you want to use to why we do iit this way.
Thank you, Leif, for this informative elaboration! Modulation by one front-firing driver of air emitted by another front-firing driver is a very interesting point!
Thank you for your comment. Vibration may be a matter of pure physics, but subjective sonic preference is not. Different cabinet materials -- or no cabinet at all -- all sound different. Which each of us prefers is a matter of subjective sonic preference -- and not of physics.
True. And also there is also easthetics factor. Speakers are usually big and we look at them. BTW interview Jonathan from OMA and ask about line arrays ;)@@whatsbestforum
my theory about super tweeters is that they complete the generated waveform and yields a more accurate transient response. it even seems to enhance the low frequency extension and tonal naturalness. ...hifitommy
Thank you, Tommy! If a waveform is entirely audio frequencies, what is being completed by a super-tweeter reproducing information above the range of human hearing?
the completion is the overtones.. partly what makes you know you are hearing real instrument. listening to a cd is like having a governor on the engine of a car limiting you to the speed limit of say....65mph because of the rolloff at 19kHz. it doesn't feel right, the acceleration gets more limited as you approach the speed of 65. also, the effect of "AIR" around the instruments. another effect is the way transients hit and are perceived. speakers with supertweeters nearly always have better overall transient response. Aperion has three levels of supertweeters that are readily available and arguably affordable, especially if compared to the EnigmAcoustics Sopranino that sells for $3600 per pair and don't have flexible cover and level adjustments. the highest performing speakers like the old IMF RSPM (which I spent MANY hours in front of), Infinity IRS, and the complete Sequerra modular system, all had supertweeters. ..hifitommy
7:35 "I am agnostic when it comes to materials" huh? He says this after talking for 2 minutes about how ceramic is better than other materials for drivers ?
One of the best (no BS) interviews on audio I’ve seen. I love the “substance” of the questioning!
Thank you very much! Please subscribe to the channel!
Great interview Ron...I very much appreciate how you professionally challenge these talented manufacturers
Thank you for the kind compliment!
I take these interviews very seriously. They are not advertising puff pieces!

I sold a set of VR4 to a aircraft engineer that worked at Pax River Naval Station
Best cabinets : 1) no cabinet, 2) made with sand/salt bags, 3) layered with different natural materials. Pure physics
