Re: 3 subs to setup
You could certainly try Geddes original proposed multisub arrangement, which was "one in a corner, one along a side wall and the last one 2/3 the way up to the ceiling along another side wall." For reference, the link below has information a...

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: Are subwoofers worth it?
If you can tell the subs are on, you don't have 'em setup right. I used to prefer systems without subs until Todd Welti introduced the multisub concept in the early 2000s. I expanded upon it to include the concept of flanking subs. Both approaches s...

Re: 7pi plan and guidance request
That room will work very well with constant directivity cornerhorns. The seven π constant directivity cornerhorn generates 101dB/W/M and is capable of over 120dB/M at full output. I would put the seven π cornerhorns along the 15-foot wall, just as ...

Re: 7pi plan and guidance request
If you have the right corners, I would suggest using the 2226 drivers in seven π constant directivity cornerhorns and make subwoofers from the 2242 drivers. Put the subs in opposite corners or somewhere distant from the cornerhorns, in a multisub config...

Re: Various questions regarding 7Pi
Answers by numbers: Midhorn questions: 1. In the π constant directivity cornerhorn designs, the midhorn blends with the bass bin in the 100Hz to 200Hz region. There is enough output from both sound sources to mitigate vertical room modes and floor ...

Re: LSAF 2017
Kelly Parham greets you in the π Speakers room I really loved the show this year. I always do, even with all the work, but this year was even better for me. We had our usual fun dinner night out on Saturday, this year with Scott and Donna Shaeffer...

Re: The bass levels
Wow! This basically sums up everything I have been putting my mind to task on. I think I will just have to get multiple subwoofers for that matter since I've never been able to fully optimize the sound in my room.
