Seas 27tbfc/g H1212 with 8in horns attached.

MisterTwister · 18th July 2011, 07:37 PM

Pair of 27tbfc/g tweeters with hot glued 8in waveguides.
I think I have previously coated domes from inside.
$50 for a pair, plus shipping USPS. PayPal preferable.

What was the effect of adding the waveguides?

MisterTwister · 18th July 2011, 09:50 PM

effect is as usual, 1-2khz boost. allows low crossover point.
Horn must be installed on a baffle, if used as it is there will be strong ripples in FR.
If desired, horns can be removed with a glue gun.

What did you coat the domes from the inside with?

MisterTwister · 18th July 2011, 10:05 PM

If I did coat them, I used thin layer of this
Cascade VB-1S PRO Quiet Kote Damping Spray 18 oz. Net Wt.

otto88 · 18th July 2011, 10:07 PM

If you did coat them, do you recall a change in the sound?

MisterTwister · 18th July 2011, 10:19 PM

no, in my experience, coating metal drivers does nothing that is audible, it only changes t/s parameters a tiny bit.
