Default 8" Hall of Fame

Hello All,

I am putting together a sub - FR - (maybe super-tweeter) design and want some help, if possible. The sub will be 18" active, with EQ. I am looking to spend up to $600 US or so per FR driver. I am considering the Tang Bands, the Supravox 215 64, the Dayton, and others, but was hoping to get some insights from people who have tried two or more in this range (92+ eff, good to 6,000+).

TIA
John

Cal - have you compared the Alpair to others? Can you give more insight into the tradeoffs?

hi
You have two choice, no three, the tangband 8 inch, alpairs 12p or supravox.
I would try the supravox.
I have tried the alpairs 12p, fostex fe127, vintage coral beta 8, and a couple more. My favorite is the alpairs 12 p. HOWEVER, I would really like to listen to a jbl le8t or the supravox bicone; I have a feeling those two would be a serious contender against my alapirs 12 p.

The Alpair 12P is a 6 1/2" class driver, not an 8", Madisound notwithstanding. Having used both the TB W8-1772 and the A12P, choose the TB for pure SPL, the A12P for finesse. Note that once proper filters are applied, the TB is ~90dB/w/m.

The Fostex 208EZ could also be considered. It cost about as much as the TB 1808.
