Midrange

[bjackson]

I am looking for recommendations on a midrange that costs either 120-150 a pair or for 2 pair.

A pair for a TMWW design, or 4 for MTMWW. The crossover points have already been (pretty much) determined. 4000hz and 400hz (4th Order L-R Active). The only one that I am willing to change is the 400hz to a maximum of 800hz.

(If it helps my tweeter will be a Fountek JP3 tweeter, and the woofers are Dayton RS280s)

Maybe the CSS WR125S ? Have you read this ?

What kind of efficiency do you need?

I always hold that the best midrange is a good fullrange, which would make me suggest CSS FR125 (or WR125) or Fostex FE108ES (a bit above your budget target but outstanding) with quite a few other possibilities (Fostex FE103/FE127/FE126, any number of Tang Bands, the Aura NS) for less money

edit: squalar beat me to the return key on the FR125

My water cooled computer was too fast for you

Efficency is not important as long as its in the mid 80s or above.

Or that you had a 1/5 as mucg to type (and i have no advantage there)

My CPUs are much more power efficiet & a nice aluminum heatsink does the job.

You may want to consider a lower crossover than 400. I'm using a WR125S as a midrange in an active system. I tried 480 Hz LR2 and hated it, there was no coherency. I am now crossing @ 250 Hz and it's very well integrated. (I'm using a 7" woofer that was used to 1500 Hz in the original Energy design).

Agreed, 300 Hz or less. The FR or WR125 give you the option of going as low as about 80 Hz.

What if I used the WR125 as a full range driver, the Fountek as a super tweeter, and then side mounted the two 10" RS270's as side firing sub system?

Similar in concept to what (RAW) Al does with his HT3. Gives an amazing amount of wiggle room for the XO points, and keeps most of the critical midrange in one driver. One can also get away with lower slope XOs.
