JBL D110F efficiency?

Walter Broes · December 21st, 2003, 01:27 PM

Hi all,
I recently got lucky and scored a minty early 70's Super Reverb with a quad of what appear to be factory installed JBL D110F's.

I love how they sound, although four is a little "much". (loud, and clean) My current "stage" Super Reverb (a modded '68 ) has two RI Jensen C10Q's, and two C10R's, and I'm very tempted to install two of the JBL's in it, along with the C10Q's or R's, for a "best of both worlds" kind of thing. (I don't need a lecture on the downsides of the Jensens, I happen to like them...)

My question is : how efficient are those JBL's, and will I even still hear the Jensens next to them? I wonder if anyone has any experience matching JBL's with other speakers..? (before I drop the chassis on my Super...)

I realise Weber speakers are great and well-loved here, but they're very expensive to get in Europe, and not really an option.

with the fender cts speakers. They have a bit more bass and highs than the alnico cts speakers. Generally clearer. I prefered them over the CTS when miking the amp up. This is the clean sound. I never pot any serious OD through them live. Except for in a shop when I tried some OD pedals out. Then it ROCKED.

Ylou will still hear the Jensens, put the alnico ones in....You need something a bit mid range, to compliment the JBL´s. They can be a bit scooped in the mids, and clinical.

Don't know how they'll match up(put the JBLs on the bottom???), but one thing to keep in mind if they're original or factory recones is - most JBLs are reverse polarity - i.e. the black terminal is positive, red is negative. Original Jensens are that way too but I don't know how accurately they made the reissues. If the amp sounds thin, try reversing the leads on one or the other.
