TB 1772 vs 1808 (sealed 2-way) question

[max2tall]

Contemplating a pair of either of these with a pair of TB W8-1747 subs as woofers in a stereo pair configuration.

A full range driver + sub active two way (which I refuse to call that horrible 'FAST').

I'll use that minidsp crossover http://www.minidsp.com/ with LM1875 & LM3886 amps.

The Question:

The 1772 & 1808 are similar, but different. My plan was a smallish sealed partition over a ported W8-1747.
I'm expecting to cross somewhere between 150 to 250 hz, but I guess could even be higher, although the 1747 is to be downfiring.

With the spec. variations between these two drivers, which is better suited to this application ?

Or does it boil down to whether one prefers 'the white one' over 'the yellow one' ;)

My vote would be the 1808/white on this one. You get more Xmax, and you really don't need the higher output of the other if you are usign a sub.

Just my 2c,

I have a pair of down-firing subs, and at 80-100Hz, no problem. Above that, I think you will take somewhat of a loss due to carpet absorption, etc. I tried a 150Hz active XO and could definitely hear that things weren't right, where with a front-firing sub, all was kosher.

Search for the Bob Brines thread on this driver, I think he is thinking it needs a supertweeter also.

I have been looking at this driver also, but due to cost and not having heard it I am waiting to hear someone else's project first

Thanks for those comments gents.

Wolf, your 2c is worth A LOT more than 2c to me, cheers

Robert, well put, I'll likely cross lower. Have had a good read of that thread earlier but the extra tweeter would be wasted on me I reckon, too much angle grinding on old cars as a kid I guess, but thanks also

Unless I've missed something, I think I've answered my own question.

WRT attached, the 1772 likes a small box much better than the 1808 ?
