Re: 4 Pi speaker stands?
The stands in that photo are 12" tall and have 7° tilt. There are lot of competent stand builders that can build to order. Most have standard sizes but will also custom build. They need to be a little larger than what some shops normally build bu...

Baffle Step
In my opinion, baffle step compensation filters can be useful, but only for a fairly limited number of loudspeaker types. I think they are way overused in the DIY community. BSC filters are best suited for little mini-monitor speakers with small baffle...

Re: 4 Pi speaker stands?
I generally suggest stands if subs are used, and no stands if subs aren't used. You can use angled risers instead.
Baffle step is actually a directivity issue, and all my larger speakers employ controlled directivity. The cornerhorns use the corner ...

Re: Multisubs with Seven Pi corner horns
Yes, I've used subs (actually multisubs) with cornerhorns. This is the best sound system I've ever heard, but you have to have a room with the right corners to do it.
With my DI-matched two-ways, I usually run what I call "flanking subs" so...

Re: 2-Pi Tower floorbounce
Yes, it does. You can correct it with flanking subs, otherwise, it's there. You can't have a midwoofer up off the ground without having a self-interference notch. All the single driver speakers, mini-monitors on stands and tower speakers have it. The...

Re: slope or slanted baffle vs stands four Pi
Click here for a list of previous posts about stands and angled risers. You'll see I recommend angled risers when used without subs or 18" stands when used with subs. The reason for two different recommendations is that rising the speakers off the...

Boundary conditions and floor bounce
Boundary loading increases SPL because it constrains the radiating angle. Where a sound source like the four π speaker in frespace would radiate omnidirectionally, boundary loading reduces the radiating angle. So at low to mid frequencies, the first-arr...

Re: Surrounds to complement 7pi and 4pi HT
I'd use one π speakers for surrounds. In fact, as soon as I get some shelves made for the living room, that's what I'll be using. I've tried them on makeshift stands and it's a perfect match for four π's or seven π's as mains, with a pair of three π sub...

Re: How 'bout a four π speaker?
I rest mine on small angled risers, which lift the front of the speakers about three inches and the rear only about one inch. This has an effect of angling the forward axis up slightly. In this position, the tweeter is at ear level when seated.Another o...

Positioning and subs
I like to use a small riser that angles the speakers back about 5°. Not much, just enough to tilt the forward axis up slightly, to put the pattern at ear level a few feet back. This keeps the midwoofers low enough that there is no floor bounce notch. ...
