Re: Amp for 4pi speakers
In my experience, 200Hz is about the limit of the flanking sub (helper woofer) approach. But I've blended the woofer with the mid(woofer) to ~250Hz in some loudspeakers and it has worked well.
Some specialized cases, like the constant directivity cor...

Re: Amp for 4pi speakers
Hi Wayne
Thank you for your quick and helpful answer!
You're right about the notch at 120hz. I always like to smooth the measurements a bit because it gives a good feeling.
A less smoothed image of the measurement from listening position witho...

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!

Re: Is a home theatre system really necessary?
You might expound upon what you mean by "actual home theater system."
My personal definition is any audio/video system that is setup to play movies. Many of them double as music playback systems for their owners.
So from this definition,...

Re: Will it work? Audio in conservatorie?
You can use seven π cornerhorns with distributed multisubs or four π mains with flanking subs and possibly one or two distributed multisubs. Either setup will work for you in that room, and I think they'll sound pretty good. I always prefer constant di...

Re: Two Subwoofers
Outside and inside are very different.
Outside, you want all sources to combine coherently. This means you want sound sources grouped together, and their acoustic centers aligned.
When two subs are placed at each ends of a stage, bass suffers from...

Re: Subwoofer Setup
That's great to hear, Barry. Thanks for the feedback!
As you and I have discussed, I'm a big proponent of multisubs but I consider the flanking sub aspect to be an additional requirement. I think that distributed multisubs by themselves only solve p...

Re: DSP for subwoofer(s)
You're right - the main thing is number and placement of subs.
I understand that you want to use a DSP crossover because it gives you the ability to choose any crossover point and slope you want, so will be easy to set the requisite ~90Hz second-order...

Re: 3Pi Sub plans, and some other questions.
You've got mail!
Vented and sealed subs are generally pretty tolerant of modifications. They are acoustically small, so standing waves don't setup inside. So basically, as long as the internal volume and port remain the same, you can expect performa...
