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.

Re: The bass levels
Equalizing the bass is not the best way to solve the problem. The best way is to use multiple subwoofers. The reason is bass problems are almost always caused by room modes, not by the subwoofers. Room modes are caused by self-interence, interactions ...

Re: Flanking Subs vs Helper Woofers, revisited
You can build what I would describe as a "detatched 2.5-way" speaker. Essentially it is a DI-matched two-way with a second midwoofer in a separate box, physically located as presecribed for flanking subs, i.e. just beside, behind and below the...

Re: Flanking Subs vs Helper Woofers
I just watched a video of an audio gathering, where several presenters gave talks on one thing or another. One of the presenters was Earl Geddes, who did a talk on multisubs:

Room modes, multisubs and flanking subs
When I first considered the multisub approach, it was prompted by papers written by Todd Welti. He did several tests that showed in-room amplitude response could be made smoother using multiple subs, and gave specific guidance about placement. His favo...

Re: Pi 7 and pi 6
Both the six π and seven π cornerhorns have similar response, a slightly overdamped alignment which results in a gentle, gradual rolloff curve. This alignment is pretty room friendly, and tends to sound smooth in most rooms but, of course, some rooms ar...

Versions and Upgrades
I agree with your assessment of the crossover. The new version (2007) is an incremental improvement over the original, not a night-and-day paradigm shift by any means. The basic design hasn't changed in many years. But having the latest version of the...

Baffle Step
In my opinion, baffle step compensation filters can be useful, but only for a fairly limited number of loudspeaker types. I think they are way overused in the DIY community. BSC filters are best suited for little mini-monitor speakers with small baffle...

Re: Multiple Subwoofers
I agree in all aspects except the points of asymmetry and number of corner sources. I realize you know my position in this matter but I'll restate just in case other readers don't.
There are two schools of thought on this, one championed by Todd Welt...

Re: Multisubs for pi7
I love basshorns, but they're just so big. Their size often makes it inconvenient to use hornsubs for multisubs.
The main benefit that hornsubs offer is maximum acoustic energy. But we really don't need maximum acoustic energy to make it ear-shatter...
