15" for sure. Total size of the box you'll stare at isn't a big difference. Driver price difference not much. Have you read the entire thread? I got the Dayton Series II's from parts express for $88 each. Think it might be pretty cool.

Bob, I have a 15" peavey black widow laying around and 3 JL 10W3s. That is why I have to decide. But as you said I am leaning toward the 15" and later buying some Dayton's.  

It sounds like confusion is all, the LSA 800 says it uses 900 watts worth of transitors. Perhaps this is the mistake.

Either way, The amp will work fine for those daytons.  

You could do either XLR or 1/4 inch, the only reason I suggested XLR is for the Postive locking.

Ok, I lied. I did taxes this week end, Forgot about those.   NEXT weekend I've got a 3 day weekend. Plenty of time to build A HWK. None of my new toys came yet.  >:(

As far as the difference in connector / termination, I also like the idea of the XLR. The 1/4" reminds me of the 1/8" stereo plugs that you would here static until you rotate the plug... not what I need.

I'm not quite sure where the notion came from that you will be immune to those problems simply by using an XLR connector. Pros using that amp may have to set it up in 4 or 5 different locations every week and put more wear and tear on every connection than you will at home.

There are many reasons to use an XLR, but the reasons stated for not using 1/4" is mainly encountered when using an amatuer grade connector. If your amp has high quality jacks and you buy pro quality plugs, you won't experience any static or degradation in the signal transfer. The shorting of the output can become a concern with certain tube outs, but generally you don't want to hot swap audio gear any way. Develope good habits from the beginning regarding your new amp.

Glad to see it coming together for you. Keep us posted!

When you say develop good habits with my amp, are you refering to hot swapping?

Yep!
I watched as a friend once tried switching stuff around and before I could stop him, the speaker outs from 2 different amps touched [LIGHTNING] and it fried both his new amps. He was not practicing "Safety First" as they say.

Not a happy camper......
Thanks, that is a practice I should start.  I've been known to yank S-video, and component cables while equipment was on.  BAAAD!! Stop it....

I don't know much about the mechanics of video, but I know many of the circuits are assembled in static free clean rooms because some of the chips used in that gear have microscopic conductors that are sensitive even to static electrical discharge that we couldn't feel. I'm sure the supporting circuitry helps to protect it to some degree, but I prefer not to temp or dare The Devil.

Quick question, in a dual driver HWK, I'm thinking about mounting the top driver face up (magnet down in center chamber). Do I set driver in hole from the top chamber, resting it on the back side of the driver flange with gasket. Or, do I install in center chamber FROM the center chamber, so the built in gasket is against the bottom of the top divider.

Or does it matter.

Reason is, ease if installation, holding the driver with one hand trying to install fasteners with other hand. Easier to just set it in hole.
