Re: Smaller 3 pi construction?
Of course, a loudspeaker like you've described could be designed and I would expect it to be great, if done properly. But don't modify the cabinet dimensions without acoustic testing, and specifically pay attention to the lower midrange. That's what ...

Re: Downfiring flanking subs ??
I see what you mean, with the wall being the 1/2 wavelength marker for the main speaker. Well, it's worth a shot, and certainly better in terms of SBIR than a conventional front mounted 3 way woofer. Thanks for the guidance, Wayne.

Re: Downfiring flanking subs ??
The two issues are (1) acoustic loading and (2) path-length distance. If down-firing, we also have the potential of suspension settling, but that doesn't apply to you 'cause you aren't talking about down-firing. So since you already have considered the...

Re: Downfiring flanking subs ??
What you're describing may work well. It's definitely better to have the flanking subs near the boundary than it is to have them near the mains they're flanking. This is counter-intuitive, I know, and it would not be true outdoors where we would want t...

Re: Downfiring flanking subs ??
Hi Wayne, Apologies for digging up an old thread, but this seems to be most relevant to my question. I have left and right speakers that are approximately 18" wide. I have them toed in at 45 degrees with the inside rear corner touching the fr...

Re: Pi Studio One Tower
I like the whole concept of the 2.5-way speaker very much. It's the best and most natural way to resolve baffle step, in my opinion. Of course, that means running the lower "helper" woofer up to the baffle step frequency. This brings me to...

Re: 3pi update / 6pi build
That's an excellent idea. Highly encouraged! I think you would probably get deeper bass from a driver like the LAB12. But flanking subs are mostly for the upper midbass anyway, for providing baffle step correction, and for mitigating SBIR and higher...

Re: Futzing with vibration control
I think John was saying that four Pi mains with flanking subs were close to seven Pi's, but that he preferred the cornerhorns. That squares with my experiences too. Where I can use constant directivity cornerhorns, I do. They don't need flanking sub...

Re: Same stereo/speakers different sound
Rooms definitely have a big influence on the sound. Think about how things sound in a small room (like a bathroom) compared to a large room (like an auditorium). The most significant influence is from room modes and self-interference from boundaries....

Re: Futzing with vibration control
It's an interesting observation, isn't it Barry? You know, in the 1980s and 1990s, I used only solid-state amps. I was quality conscious, so I used good equipment but none of it was tube gear. So I was familiar with these speakers on amps that could...
