Re: My 3π adventure
I like symmetrical multisubs, which is a Welti arrangement. You can use such an arrangement and also include flanking subs.
Place the mains with flanking subs outboard. They are just a little behind, beside and below the mains. They are stereo subs...

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: 3 Pi plans
That sure is a nice looking pair of three π speakers! I like the stands they're on too. They'd be perfect for use with flanking subs.
The way to implement flanking subs is to use the left and right preamp outputs as input signals for the left and ri...

Re: 3 Pi plans
Those look stunning!
To improve the upper midbass and lower midrange, you have two options that come to mind right away:
1. Upgrade the midwoofer to the Definimax 4012HO. It's a drop-in swap, with only a single capacitor change on the crossover. ...

Re: Amp for 4pi speakers
It looks like you've done a very good job already, and I have no doubt you'll tweak your system further to make it even better still.
Congratulations!
You're "working with what you've got," which is what 90% of us have to do. High-qualit...

Re: Horn mouth vs. front baffle or "speaker cone"
I definitely understand what you've described. Geddes suggests placing one sub high in the air like that, specifically to deal with modal smoothing in the vertical dimension.
My guess is your troublesome mode is probably in the 60-80Hz range. Partly...

Re: Ceiling speakers
I have read about that as well, it doesn't make sense to me.
I believe there is some type of system using ceiling speakers called "atmos".
I wonder if perhaps subs (being low passed under the a-typical 80Hz) would work ceiling mounted, with l...

Re: The subwoofer volume and crossover
I was generalizing the concepts and using "round numbers" in my earlier post above.
Flanking subs are setup to blend generally in the 100-200Hz region, but in practice the blending region is shifted a little lower than that. Distributed mul...

Re: Small-room acoustics
Actually, small rooms are harder to work with than larger rooms. The reflections and room modes are more intense in a small room. Speakers that can provide uniform directivity help reduce problems in the reverberent field, above around 200Hz, and as yo...

Re: The subwoofer volume and crossover
The answer to that can range from simple to complex. So let's start with simple, move towards more complex topics and then leave it to those interested to research further.
The simplest way to setup a subwoofer is the way most home theater systems ar...
