Re: Three Pi and Three Pi Sub Plans
"If you can hear noticeably louder bass or midbass with the subs on, then they're set too loud. Thus is true no matter if they're set as multisubs, flanking subs or traditional subs" I guess most car 'audio' guys that didn't get the memo. Som...

Re: Three Pi and Three Pi Sub Plans
I've always loved ribbon tweeters too. Back in the 1970s, the EMIT tweeters in Infinity speakers were oh-so sweet to me. They offered much greater extension than compression drivers of that era. But they lacked dynamic range. They were relatively fra...

Re: Flanking subs
All three subs are multisubs. The two nearest the mains are flanking subs and the distant one is a distributed multisub. Check that your plate amp DSP can support 100Hz second-order and 50Hz fourth-order Butterworth slopes. I'm sure it does, but che...

Re: 3 Pi sub questions
The three Pi sub kit is really just a woofer and port material. We also include the connector panel, a "π" logo and a printed copy of the plans. There is no passive crossover included. The crossover, as you've rightly indicated, is specifi...

Re: 4PI Plans Request
High-pass at 50Hz fourth-order is fine. As for the delay, please remember that what we're doing with flanking subs actually requires some delay. The modal range is caused by a multitude of phase interactions from reflected signals. There are mul...

Re: 4PI Plans Request
The flanking sub low-pass recommendation of 100Hz second-order is empirical, so you can consider it a starting point and not a hard-fixed number. However, I have found that the slope is always better being gradual than it is being sharper. Fourth-order...

Re: 4PI Plans Request
I think that's a good way to go. Run the flanking subs with a 100Hz/2nd-order low-passed copy of the signal sent to the main speaker each sub is flanking. Run the mains set to "large" so you blend with the flanking subs. The mains should be ...

Re: 4PI Plans Request
You've got mail! I agree with Barry about the JBL 2226H. It is an excellent midwoofer. The flux stabilization ring in the motor structure reduces distortion down to the levels normally only seen in horns. When combined with a horn tweeter, you have...

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....
