Back in the 90's i bought a pair of Aura 1808 woofers and made a set of 24 cubic foot corner enclosures 1 1/2 thick, crossover at 100hz, close to 300 pounds, way over built enclosure with a baffle on the face of the enclosure that i could remove. I T...

[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...

All thinking about ULF are usually centered on 3 subjects:
drivers, topology and amplification. Even though these 3 subsets very much intertwined
I still would like to talk about it separately. We do presume that we have the proper
drivers for pro...

I want to share what I feel is a good application of an injection channel, as introduced by Romy. But this is different and also useful and i can tell you it works and very well. Of course, I do not recommend to use this application in the same exact...

Thanks Romy,Yes, I received your advice in the past privately regarding proper size for 1808 enclosure, and I thank you for pointing me in right directions. Yes, sealed box is simple calculation using e.g., WinISD. I am experimenting with&n...

Hm, the 18mm out of 50mm in “fully in-gap mode” for Aura? It sounds too bad. The last time I touched this subject it was 6 years ago and I remember I had better impression in term of the numbers.
I just looked at the Aura page:

Congratulations, Romy, I think you just re-invented the ISOBARIK loudspeaker.
Although, Linn's Isobarik implementation of two drivers moving in parallel separated in a small chamber which would be nearly in constant volume (and pressure) couldn...

I got home today and was listening the music of my carpenter in my basemen cutting the wood for my midbass horn. I was slowly thinking about the location of my perspective lower bass channels. The Midbass Horns, if the things go well, will cover...

It is strange topic that I always had difficulties. I have a storage filed with all possible audio goodies, starting from some exotic goodies that people would chaise on junk-years for years and ending with Jimmy Hoffa’s skeleton. It is not that...

I am usually not a big fun of somebody refer to eBay Items and I myself do it very seldom. Still, here I am as I think it is an interesting deal for someone. There is a guy out there that is damping a few of Aura RS-8.1 bass modules.

You know, it surprises me how much less fan to listen my playback without ULF. Nope, the playback does not sound bad from audio perspective without ULF but it for sure a bit different experience. From a certain perspective to be in a room with U...

[quote user="jessie.dazzle"] In the case of a normal ranch style home (one level, no basement) out in the burbs, the attic is wasted anyway; you could put it to use, and if necessary, modify the roof, letting the drivers live up under decorative ...

Hi Romy
a good sound in a room does not depend only on the speaker chain, but essencially also of the room acoustics. Probably many of the Trio systems didn’t sound right just because of that…. I was at Holgers Home in Lautersbach back in 94. He ha...

Romy,
Sorry for taking so long to get back to you… (this being the summer time in a Latin country, I still have no internet connection at the new place).
Quote from Romy “If your lower bass channels run from 40Hz and down then the PS, size of the c...

I completely agree that in a home setting, even if you love "Drum & Bass" and Hip-Hop, you will never ever use anywhere near 2" of cone excursion.
