Re: Low Pass
That's my aim, flanking subs. So I'll give that Rolls crossover a try using the stereo low pass. For distribution subs using plate amps, whats the best method of running a signal to it? Doesn't running a long interconnect cause problems? I wondered if I sh...

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: Low Pass
The problems you're talking about are pretty common. They're impedance-matching problems. The load of the passive crossover is interacting with the output impedance of the preamp. And those inline filters are really lossy too, so I don't like using th...

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: Three Pi and Three Pi Sub Plans
Thanks for the great response; that's exactly what I was trying to understand. Again, the design seems very elegant, and I wish I could accommodate the cabinets in my room.
I have been thinking about building a baffle wall, however, as I already have an...

Re: Three Pi and Three Pi Sub Plans
What you propose sounds like it would work pretty well. You would lose a couple synergies that are designed into the three π and four π models though. And you would need to test your design with acoustic measurements, paying special attention to the lo...

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: Definimax 4012HO - End of Life
Hello
Following this one very closely. Both speakers are widely available in Europe and
quite inexpensive. Even the B&C which can be a expensive brand, can be found below 200€ here.
This would give me the perfect upgrade path, by using existi...

Re: Definimax 4012HO - End of Life
I'm not ready to make an announcement, but I can give a status update.
I have a pair of Eminence Delta Pro 12A woofers and a pair of B&C 12PLB100 woofers here to test with.
Both look like they will work very well from modeling and from free-air...
