Hello,
Bought these for a speaker project, but no longer need. Lots of low distortion, clean output. Made for a closed box of decent size, not ported. Could also work in IB/OB/dipole, though I didn't try that.
$147 each, or $273 for the pair. Prices are firm and fair. Local pickup in Los Angeles only!
