three π / four π comparison
I think you've probably seen the datasheet for the four π loudspeaker:
four π loudspeaker performance dataI haven't had a chance to do a spec sheet like that for the three π, but I do have a lot of data gathered during the design phase. I will make tim...

Re: Possible move
Walk across the floor, tap your feet. If you hear a hollow sound, then that will also be what you hear when playing your sound system.
I love the serviceability of a raised hardwood floor, the ability to get underneath and work on pipes and what-not....

Re: 4Pi crossover issue
Smooth bottoms is what really drove the decision against plate-through holes on the crossover boards. Even if you cut off the sharp edges when removing the leads from soldered components, you'd still have the thickness of the solder joints which wou...

Re: 2.5 way using two JBL 2226J with B&C DE 250 & H290 horn
A few thoughts:
First, a minor clarification. The H290 is not a BiRadial horn. "BiRadial" is a JBL trademark and it is a constant directivity design that has a diffraction slot in the throat. The H290 is a radial horn that provides consta...

Re: 3 Pi Build
Something is not right. This model is one of the smoothest of the line. You didn't say what horn you were using, but remember that these designs are specific to the parts called out in the plans. You can't necessarily substitute parts without design c...

Re: Pi 7 and pi 6
Hi Dom - given that you are already using a large pair of Tannoy's I would expect any bass issues to be the same as you currently are experiencing! As for me, going back over the whole process, the bass problems were more than just room based.

Re: three π speakers at LSAF 2010
Same speakers as yours, just with that really sexy TD12S. Night and day there, you might spring for a set of upgraded woofers if you can.
As for stands, I usually don't put them on stands unless I'm running subs. This prevents floor bounce and gives...

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...

Re: 3 Pi - Could it work for me?
I run a 10 watt Audio Note amp for my main home stereo and home theater. It's plenty for either model - three π or four π - but do remember the four π is 3dB louder. This isn't night and day, but it is noticeable. With 10 watts, I'd say either will pl...

Re: Versions and Upgrades
So how do you get gradual roll off like a sealed box, but using a ported box? It is just over damped? Is this a low "Q"?
Thanks.
