Okay, to make sure I don't toast my new HL10a driver in my Tuba 24, I want to make sure I set my limiter on my Driverack 260 correctly. Here's my logic: HL10a is a 300w RMS unit @ 8 ohms. I've read that some people believe it doesn't hit power compression until 400w in a T24. I have a Mackie FR2600 ...

Home Depot's got them up my way, stocked near the door hinge and weatherstripping area. $2.50 ea CDN

You know, not to be an ass, but I haven't found any ooze problems with PL Premium - Maybe it's because I do a lot of caulking, and I'm familiar with using spray foam (talk about ooze and drip there!). No gloves, no mess on hands, no problems. I've got some smooth 1 pass PL joints that don't need any...

Ah, this may work best on a Tuba then - You can't fire it up properly until you're done (unless you want to keep reinstalling and removing the driver) and by then, how do you get to the areas deep inside to fix your mistakes? :-) Many checks can be made, this is a quick one you can do while it's sti...

Hey, Try shining a halogen work light inside your build, and check the seams from the outside in a dark room. You may be surprised that your caulk/PL has a few hairline cracks or pinholes. If you've got a good tight seal, you shouldn't be able to see light through the seams. I found a few little spo...

They don't work, tripping either too early or too late. Having a limiter in your rack is a must. Ah, that's why no one is talking about them.. okay. I do have a limiter in my electronic crossover (DBX Driverack), was thinking of building in more protection just in case. I guess you can never make s...

Hey, are these a good idea? Are they known to colour the sound?

Should you pick a 300w breaker for a 300RMS/600WMusic speaker like the HL10a?

Comments?

I would not use four ply 1/2", and say so in the plans.

Ah, busted - for want of a ply.

Making the holes can be a bit time consuming but you drill once and lift often, so I'm all for weight saving. Well, I'm thinking the weight savings of drillin...

Okay, so Parts Express is the place I should be getting them from (I wonder if they get slightly different stock from the manuf's?).

If I wanted to get 16 good/similar sounding Goldwood 1016's, how many do I need to buy?20? 30?

Yeah, I think I'm stuck in the "What? The world is round? You've got to be crazy" type of mindset. It's hard to shake, tho I do realize that more speakers will even out sound - I just never thought about it with Piezo tweeters.. it would be sweet to shed the extra 200lbs (2 CD horns and th...

That's very interesting on the tonal qualities of the various tweeters. I only have limited experience with piezo tweeters, having heard them on some mid-range car 6x9 speakers, and then for a direct radiator type of PA system I built before stumbling on Bill's site. What I used in the past was a pa...

Hey all, I'm getting ready to build my first BFD cabs (Tuba, DR250) and I've been sifting through the forums trying to learn as much as I need to know. I've got a few pointers here that I'd like to get confirmation on, maybe have someone expand on them a bit. If people wish, I'd happily refine all t...
