Don’t know whether named amps have variable gain (or how they otherwise match here as a fixed value), but you could use the SET(‘s) for the HF/MF horns and the bridged 275’s for the 15” units? Or else I imagine a pair of stand-alone SET’s would do well up to moderate volumes.
SET on JBL Everests - Mouse breeding an elephant?
I have a set of DD67000s and I’ve been running them on a pair of bridged Mac 275 amps. I’ve been quite happy with the results even though most advise a lot more juice. Lately, I’ve been hearing interesting things about the Elekit TU 8600s and I’m curious how that would work on the Everests. Most of my listening is to acoustic guitar, jazz ensembles, piano (classical and bill evans jazz), and intimate vocals at fairly low volume with the remainder being orchestral/symphonic, early rock, big band, Texas swing at higher volumes. Room is 22 X 40 with vaulted ceiling. I’m thinking of adding the SET for the smaller scale stuff and leaving the 275s as they are for the rest. Thoughts?

The real treat it seems would be running the DD67000’s actively - have you considered that? https://positive-feedback.com/interviews/greg-timbers-jbl/ |
Wow the active system sure looks complex. I wonder why TWO bass amps.. and 4 amps per speaker. A pair would be fine. Mac 275s aren't at their best when stacked like that. Series or Paralleled, the SQ suffers. I'd use one Mac 275 get a couple of good NOS Telefunken signal valves and a pair of good SS bass amps. Honestly for 1000.00 USD I could tear the pants off the set up you currently have. No SET involved. Those 275 sound a LOT better unbridged. You could use one for the mids and one for the highs or one for both. THEN serious high watt cool running class d amps for the bass. Me I'm not into looks when it comes to BASS amps.. I'm looking for reliability, sound quality, big clean power supplies and enough dampening.. period!! I like circuit breakers in my bass amps too.. I use 12k Behringers on everything now.. 1000hz down nothing better.. and good to 1 ohm. ONE would bounce those JBLs all over in the BASS section, TWO one per side and 2 MC275s.. for the lows and highs.. You'll think 22 X 40 with vaulted ceilings.. You'll think Amphitheater!! BTW they are 3-500.00 each.. I do a little fan mod and they are completely silent.. 3500 + watts per channel at 2 ohms 1750 @ 8 ohms MC275 bridged.. ?? I remember VERY well. I did MC240 twice, bridged, it took a lot of work to make them sound right.. 275s were just LOUD.. VOT speakers.. 80s... They were used for square dancing 150 x 150. I loved that job... Russco record players too.. Regards |
