Superb small tweeter for smaller speakers

I'm using this crossed over to a Fostex FF225WK. Not an ideal midbass for a two-way, but in this case there were some special constraints. The little tweeter is beautiful, and has only one small flaw, it can't be crossed over very low, since its Fs is fairly high, almost 1K. Other than that, it's a great tweeter, and because of its smaller flange diameter, it'll be ideal for smaller speakers (mating to 4" or 5" midbass drivers) or for smaller MTM designs. I intend to use this with the SB15CAC in a small standmount MTM two-way too.
