Did you ever sell the TAD 1602's you were parting out over the summer? If not, I'll take 'em!

I must have read 500 posts today on Hi Eff and Pi, and finally fell over your discussion of using these babies in a 4PiBR Pro 3.5 ft3 box, as well as the fact that you had a pair (at some point) to sell.

I'd put the cabs on 11" mass-loaded stands, with Bill Martinelli's horns and Eminence PS 2002's on top of them, using your 800hz (??) xover. I'd upgrade the 2002's when I recover from the shock of the initial outlay!

I would expect this combo to be quicker, lower distortion, sweeter, albeit less efficient than the Theater 4's. Does that make sense? I'm after horn speed and effortlessness used with SET's, not ultimate SPL's.

Thanks!

Drop me a line, offline if you like, as to the total including shipping to 06033, and how I can make payment. I'm rarin' to get started, now!

Hmmmm . . . What driver will suit Bill's horns and play nicely with the 1602's in a two way system? 2426's? TD2001's (Gulp!) I really don't want to turn this into a 3-way circus if I can help it.
Keep your ears and your mind open.

TAD quotes the 1602's range as 21hz-2k, crossing over nearly an octave lower - 1,200hz ought to be okay, shouldn't it. Again, maybe not ideal . . .

I would expect the 2426 or TD-2001 to work better, and allow the 1602 more breathing room, since they are spec'd as having usable ranges of 500hz -20khz+.

I'm not being argumentative, just trying to learn here, guys.

Thanks for the input!

You've got mail! ;-)

Okay, 3.85 is a touch bigger than the Pi4 Pro, but that's considering external dimensions, as if the walls had no thickness, and the 1602 occupied no space at all. Hmmmm . . . How do I ramp up the externals to get 3.85 internal using 3/4 stock with a doubled baffle?

In terms of proportions, I'd like to have 29"-30" height and 17" width to get Bill's horns to the right height for seated listening (spkrs on short stands), and match the horn width.

If I take the Pi4 Pro cab, and arbitrarily bump each dimension up .75" for illustrative purposes, I'd have 26.75"x18.75"x14.75" or about 7,400 in3 or 4.3 ft3 externally. Reshaping this, maintaining the volume, I'd have 30"hx17"wx14.5d.

I'll want to hit the volume more precisely, which will change the dimensions, but will those sort of proportions keep me out of trouble? Is the height too close to being an even multiple of the depth?

This is getting exciting - Diverse drivers rolling along in brown trucks all over the country . . ! ;-)
