Re: Pi 7 Information
I've sent plans for the seven π cornerhorn.
Curtains are particularly helpful for constant directivity cornerhorns. They tend to help most at HF, partly because lower frequencies are within 1/4λ of the wall and don't reflect, and partly because at hi...

Re: High-pass on the 4pi?
High-pass at the Helmholtz frequency of the mains. The multisub configuration is not limited to direct radiators, but can be employed with hornsubs as well. Delay on the mains is really used to match the acoustic centers, to compensate for the extra de...

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: 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: Super Tweeters
First, a technical answer then a more actionable one:

Hi Wayne,
I've recently placed my 4 pis in the corners a couple of inches away from the adj. walls and love the sound I'm getting. Very coherent with good balance from top to bottom within the limits of the design (i.e. quite good). The bass is strong a...

subwoofer use for old cabinets
A question for you guys: Would it be worthwhile to hook up my old Theater 4s without the horn and low passed to augment the bass from my JBL 4 pis? I'm mostly interested in managing room anomalies much in the way Wayne suggests using multiple subs. Any sug...

Re: 1pi or 2pi for surrounds?
