Re: New Jack 112 build

If I use two pairs of Jacks, would something like 2x525W at 4 Ohms be enough (Crown XLS 1502)?

Re: New Jack 112 build

Looks good. Concerning PA amps, lots of knowledgable peeps will chime in. There are hundreds of possibilities, it depends on weight, cost, reliability, reputation, size, availability.. I like the old-fashioned lead sleds. You can get them for very little money second-hand, and I like the way they s...

Re: New Jack 112 build

Thinking further ahead, what would be a good value PA amplifier for two (or maybe four) Jacks? What do I need to look for?

Re: New Jack 112 build

Never mind, found many offerings in Germany, luckily, one of them ships to Belgium.

Re: New Jack 112 build

Two Jacks are finished, but I did not have much time for the other two. But it's coming... It's just hard now to find the 2 Kappalite 3012HO speakers, and several other options aren't available anymore, at least here in Europe... Since I cut the baffles for a Delta pro 12 or 3012HO, the Beta 12, 201...

Re: New Jack 112 build

Thanks AntonZ! I would use the same pvc glue, but I already painted the diffuser black so I thought maybe hot glue would be better... Good idea to use the weather stripping!

Re: New Jack 112 build

Finally found some time to get back to the Jacks... the sawblade for pvc I got did an excellent job cutting the tweeters. Happy with the result. So now, which glue should I use to glue the painted pvc diffuser to the array and the array to the brackets (or do I screw the array instead of glueing)?

Yes indeed so for 8 Ohm max 0.4 these two would be OK. The different in price is minimal between these two...

Re: New Jack 112 build

I found several 0.6mH air coils, does it matter which one I get? There is no AWG specified in the plans if I'm correct, only max resistance. The less resistance the better I guess? I assume this one's OK: JANTZEN 0,600 MH AIR CORE COIL CU 1,4 (15AWG) RDC 0,230 OHM and preferable over JANTZEN 0,600 ...
