Neo option for driver, cheese holing all braces, using flat piezo array...
Out of curiosity, which neo driver would you have chosen?
TBH, when you throw in price and weight, what you've picked is probably it.
There's options from a number of sources, but they weigh more,and cost more.

Re: Multiple cabs

Sorry yes I meant the 12c seems to have more output. I only have 4 cabinets that have regular lab12s out of 10. Please bookmark this thread now, and keep referring back to it. In this thread: https://billfitzmaurice.info/forum/viewtopic.php?f=2&t=24492&p=271537&hilit=lab12c#p271537 That applies to ...

Re: Compression horn tips, tricks

Just ordered 8 of the PRV Audio drivers That choice of driver has me a bit bothered. You did say up above "not at any cost light" bit it looks like the only thing going for them is the 2.36 pounds in weight compared to say the beta 8a which is 6.6pounds, but is a recommended driver with no hole in ...

Re: Multiple cabs

Looks to be on paper that the regulars can take more volts. Dan, There's a little trap here. The lab 12 C has lower impedance. So it has a lower voltage limit than the regular lab12. But, output is the same! I reckon the answer to the lab12C hitting harder than the regulars for the OP (based on pre...

Re: Compression horn tips, tricks

Which means a total redraw of the plans... Actually, it's not that hard. All the dimensions except one (the length of the inner horn) extrapolate easily and can be done while you're drawing out the cab. The horn length only changes 1/4" which is negligible. Figuring the bracing takes a little more ...

Re: Hello from Danville Virginia

No wonder you're struggling lol. Eminence Deltalite II 2515, Eminence Kappa 15 and Delta Pro 15, premium driver is the Eminence Kappalite 3015, from my older plans for the J15, I don't have the lite plans. It's up to you if you want to go the way you're suggesting. After all it's your money. It does...

Re: Multiple cabs

I feel the output is better with the lab12 vs 12c. i wish i had the free time and equipment to test it for sure. but idk to me they feel louder. Which is what i need. Maybe swap them all to Cs. idk. I think in the past you've said that you reckon the lab12c loaded cabs hit harder? Rather than the l...

Re: Compression horn tips, tricks

I'd say closer to 5-8 pounds, as it's only the outer pieces. I'm considering doing it completely out of 1/4" and 1/8". The sales page for the DR200 says "weighing in at less than 30 pounds". I assume that's complete and not bare/empty cab weight. However, in reading through some of the build thread...

Re: Hello from Danville Virginia

The wedgehorns have a bump in their response for vocals, because that's what they are designed for. That's not necessarily good for music. They are also not designed to sit with the driver perpendicular to say a tuba. I reckon a Jack 10 might be better for your half plan, and will have greater sensi...

Re: Multiple cabs

The limits of the the lab 12, and the lab 12C are different. I can't remember if you ever told us that some of your cabs are lab 12C loaded until a while later, or if you ever asked if the limits for the 2 types of drivers are different. It's a pair of series wired lab12's that have a 100V limit. Th...

Re: Multiple cabs

shouldn’t I limit them to 80-90v either way? That’s what I have been doing. Why, when 80v into 10 ohms is 640 watts, 80v into 14 ohms is 460 watts ? In other words, it's a smarter move to replace all the lab12c's with lab 12's, not the other way around. How do you connect the 2 cabs per channel? As...

Shouldn't that be Lab 12 (6/2 +2) = 5?
