My Three-Pi sounds perfect in the voice region, I used the orig. box size But, I ported mine a little higher around 45 hz. I am using a solidstate amp so the tone may be different. Box size 20x30x14.. After modeling on Boxplot and other programs I have found that a increase in box size may start to add unwanted Boom. The 1 or 2 Pi's have a sweet and silky treble that is sweet, But the 3-Pi's sound more true to life. I wouldn't say the 3-Pi's sound better but, they are higher fidelity and of course will put out more Dbs with bigger Amps. I differ a little on the crossover values But, this may be due to taste and Vertical position. I have tried different woofers like the kappa Pro 15lfa and they did not sound as good in the Voice range. I like the tower design and will try it with the 3-Pi drivers and crossovers soon. Thanks for the great pix's.

i modeled the speakers with something King sent me for port placement. a few very small bumps that might be as much as 2db i guess. that was leaving the stuffing as default on the spreadsheet. adjusting the stuffing to something a little thicker makes the response curve very smooth.
so looks like i got lucky on the port placement Very Happy

That's excellent! Makes you feel better, doesn't it? Very Happy

Now you know the fruits of your efforts are not only aesthetically pleasant but also acoustically right. That's the goal!
