How do I prevent damaging my JBL 2245H's with too much power?

We had a dance here using a valve amp on 4 scoops. I didn't hear enough of a difference to be convinced valve amps are necessary.

Some people seem to be religious about the valve sound.

Have you been to a Valve a torn or Sounds and Pressure dance? How was the sound? Valve amps are not the only factor though.


Out of interest, what valve amps did you use, and what scoop/driver combination?

A local sound system here in Auckland, New Zealand had an English person build a 1000W amp. It powered 4 scoops with (I think) PD's.
Is that too vague?


Thanks. I wonder if the amp was built by a man called John Chambers. Several were built a few years ago. He's not the only builder tho.

When it arrived in New Zealand. Apparently it didn't work. It took a bit of rebuilding as I understand it. The buyer was disappointed. So the builder isn't respected.

Not Mr Champs then, because he is respected. Was the designer for some guitar amps dating from the 60's. Maybe, if you are interested in valve amplifiers, Google John Chambers.
Why get one from England if builder available from NZ?
Valve amps tend to need maintenance input to keep them running sweet.

If the amp your mate bought was fundamentally flawed via design, then
yeah, resect lost.
Sorry to hear of your disappointment. As said by others, valves need dedication. You could get an equally vintage sound via old design MOSFET amps.  Mofets also have some ofthe characteristics of valves. I also own Mr Eddie early mono block mosfet amps, and when pushed sound fantastic.

Did you check the track I was on about earlier?? Wink

You mean John Holt's ali baba? Yes

Would I compromise sound quality by not using a reggae pre amp?
I want to plug everything into an Allen and Heath Mix Wizard 16 channel mixer. 
I would utilise fancy tube phone pre's outputting line level to the mixer. The mixer would feed a crossover and the 4 way crossover over come back into 4 mixer channels that wouldn't be assigned to the master bus feeding the crossover, thus avoiding feedback. But outputting directly to the amps.
Clever eh!
Then I would have heaps of channels for mic's, effects and 8 track multi track audio for dubs like Mad Professor does.
And of course I could control the crossover levels from the faders. Or maybe this is unnecessary if I just adjust crossover levels on the crossover? I wouldn't want to accidentally press the 'master bus' assign switches on the crossover channels creating a feedback loop.

Can be done that way, just depends on your own preference.
sometimes known as a ghetto pre. Nobody has to have a reggae pre-amp
