Re: MiniDSP
Digital filters are awesome because of their flexibility.
In the case of loudspeakers - and particularly controlled directivity loudspeakers - you have to be careful with your choice of filters because they affect summing through the crossover region....

Re: Low Pass
The 100Hz at 12dB/octave (2nd-order) slope recommendation is specifically for flanking subs, which are a type of multisub arrangement. Distributed multisubs are usually run lower and with a quicker slope, often 60Hz at 4th-order or 80Hz 4th-order. The ...

Re: Three Pi and Three Pi Sub Plans
If you can mount the speakers in the wall, that's perfect because it removes self-interference from the wall as well as removing any baffle step. It really is the best option. You can setup the subs as distributed multisubs rather than flanking subs.

Re: Definimax 4012HO - End of Life
Check out this document from Eminence's website:
Understanding Loudspeaker Data
It shows what each of the electro-mechanical parameters describe.
As for flanking sub setup, generally, we want 100Hz, second-order. I've found some combinations that a...

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.

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: 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...
