Re: Definimax 4012HO - End of Life
Do not forget that this design almost requires flanking subs for deep bass response. You can consider it to be a three-way design with the woofers detached.
They are adequate without subs, but certainly not optimal. They get better bass extensio...

Re: Improving acoustics in living room
The "most valuable change" is the one that provides the most benefit. That wasn't meant as an impertinent reply, but rather to highlight the fact that different environments have different problems.
The most common problems indoors are rela...

Re: LSAF 2019
Looking forward to seeing you!
I didn't reach out to anyone about seminars this year, nor did I ask for a conference room. I did that the first couple of years in Tulsa, and also early on in Dallas. But after the second or third year, I started maki...

Re: 3 Pi plans
Thanks for all the information on flanking subs and the corner horns. After much consideration and I think that I will upgrade my 3pi.s to 6pi cornerhorns. I think that way I'll make the most of my limited space.
The back wall is about 3m wide and if I...

Re: 3 Pi plans
Flanking subs are really just "helper woofers" except that they are generally tuned to provide deep extension. That way you get both benefits - Blending in the 75Hz to 150Hz range gives SBIR smoothing and extension below that gives more deep b...

Re: Making your audio sound better
Check out the links below and then do further study by searching terms like "room modes," "multisubs" and "flanking subs." Might also study the concept of the "reverberent field" and the difference between the &qu...

Re: Questions about H290C horn and 3Pi Subwoofer
The volume displacement of the H290C is 125 cubic inches sans driver. But the internal volume offsets are taken into account already, so don't "grow" the box to account for internal offsets again. More information about the H290C Horn/Wavegui...

Re: More on subs
Very good experimentation, and useful information. Thanks for the feedback.
I have almost always found that flanking subs are a first priority, and one or two distributed subs are next in priority. But sometimes the priorities switch - Rooms that ha...

Re: Amp for 4pi speakers
Equalizers aren't terribly expensive. I'm not a big fan of the old analog graphic equalizers but do like parametric and digital equalizers. The MiniDSP is fine.
I must admit that all the drivers I use need pretty large boxes. So I'm not sure ...

Re: Amp for 4pi speakers
The flanking subs did exactly what I would have expected, which was to reduce 15dB ripple in the 100-200Hz region to 6dB ripple. That's a "textbook case" of what to expect. Flanking subs can smooth the range a little lower than 100Hz - usua...
