So, I delivered the new T39/SLAP rehearsal system to my dad a couple weeks ago. We previously had him using 8" Fender Passport tops and an inexpensive 12" ported sub powered with a Behringer iNuke1000 DSP.
Here's what I noticed;
-By ear, a single 2x6 shorty SLA Pro (16ohms nominal) required at least 6dB
less input gain to have roughly the same output as the 8ohm Passport speaker.
-The highs in the SLA easily outperformed the Passports two 2"ish splayed cone tweeters. I quickly realized I'll need to deploy a de-esser or start pulling some highs out of the mic's now. Seth's sinister esses stick out sorely sassy sister!
-This system has more volume potential than my Dad is likely to ever use, even other than rehearsal situations, in intimate indoor gigs. A lot more. Thinking I could have easily covered his needs with the smaller amp (200wpc) and the Basslite S2012 driver instead of the 3012LF. Always an option if I need or want to swap them out for whatever reason.
Anyway, that's it for now. Thanks for the great design Bill.
