Re: Subwoofer Crossover
The MiniDSP would work nicely, because you can use it to set whatever low-pass frequency and slope you want. I'd probably lean towards that since it gives you such flexibility. Sub crossovers are easier to dial-in than the crossovers inside the mains. ...

Re: 4pi plans and questions
You've got mail!
Four π speakers are perfectly suited for soffit mounting, in wall, baffle flush. See the following thread:
four π loudspeakers at NJCU sound labAs for the surround speakers, I really like using one π or two π speakers as surrounds. ...

Re: 3 or 4pi for HT LCR and flat-packs?
I'll send plans but first decide which model you prefer. There are some threads here that discuss the differences, so look through them, decide which model you want, and let me know. I'll send plans right out.

Re: PA system using Three Pi as Mains and Three Pi Sub(s)
Definitely don't run a single sub in that space. You've gone to the trouble to build the room right but you'll throw all that out the window if you just use one sub. There's no way to make that room right in the modal region with just one sub. So defi...

Re: Subs as 3pi stands?
If putting the mains on top of the woofers is all you can do, then you can't take advantage of modal smoothing using multiple sound sources. The mains and the subs will sum the same (either in phase or out of phase, depending on how they're connected). ...

Re: how'd we get here (or where is this)?
Altec made excellent speakers in that era. Not too bad by today's standards either. But they definitely don't compare with a properly designed modern matched-directivity two-way (waveguide) loudspeaker, even though they look similar.
The following d...

Re: JBL 2226H question: is this right?
That's good. Run a couple subs flanking, and my experience is they are generally best run out of phase with the fours. Just the opposite for threes, but that's a different story. Then run the other subs further away, nearer the opposite wall.
Room mo...

Re: What do you think about this Pi speaker layout?
Looks good. The subs flanking the mains will smooth the upper modal range, from ~80-200Hz. In order to do that, low-pass them around 90-120Hz with a gradual slope, second-order preferrably. Let the mains run full range. If there are no noticeable lower f...

Re: Bloated Car Bass
This accounts for the tactile bass of a kick drum or low B on a bass guitar that Shane mentioned - you have to be there and experience it yourself to understand this. You can actually feel the bass, just as you would at a live rock concert. This can be...

Re: Bloated Car Bass
There is one very good thing that happens in cars: The absense of room modes in the bass. The pressure region goes way up high - cabin gain actually works all the way up to about 60Hz. It just isn't hard at all to pressurize a couple cubic meters and ...
