Thank you for the reply.

Which DriveRack are you using?

Nice work! How does it sound?

I have a friend that wants one of these. His system is all analog with Alto powered cabs for mains and monitors.

I’ve never needed one so I don’t have experience in this gear.

Opinions, comments, and experiences welcomed.

That sure sounds like a keeper to me! I'd love to hear one. I'll have to do some digging around the area!

So… what is the rule of thumb to match amp power to speaker rating? Would it be 100% or more for headroom?

I like a rack mounted power amp mated with either a PreSonus Channel Strip or a Sansamp RPM.

Decisions abound…

Here's the switch I selected:

Just an SPST should do it on the High Pass Filter "+" , correct?

This leaves the low pass filter active?

If 2 J12Ls are used bass, Bill suggests the top one be full range and the bottom is woofer only. With that in mind, with both being Melded Arrays, on the bottom unit, can I put a switch on the jack plate to not use the Melded Array or a separate jack to run the woofer direct with no crossover? Or is...

I am forgetful of the basics. I had all tone controls halfway, but on the GK they are all boost, not unity.

(OK, read the amp controls, dummy)

Many thanks to my friends and the allmighty Yoda, Bill Fitzmaurice. I’m humbled.

I'll review EQ and go with screws.

I have obviously made a mistake on rear panel bolts! I’ll make new back panels for both to accommodate more bolts. I’ll patch the buzz in the meld diffuser. What about the farting on the “E” string? I’d certainly like it stop. I’m hoping for a tighter sound there as well as the other strings are. Th...

Yes, the cabinet is 1/4 inch. There are 8 bolts on the back panel with gasket tape. No air comes out the back when testing. Using it last night was not much better. Just about any note on the low E string farts out running at half volume. Other than that, the cab sparkles with great punch. I wonder ...

I'll make the change. The flat pack I got had all pieces 1/8".

Also the center post in the melded array is what is also buzzing. Wherever I press it, it will stop. What to do about that picke?

Yes.

Using an iPad app, f generator, has been a boon. Here's what I've found.

The entire back is vibrating at low frequencies. It's better if I hold my hand on it.

I'm checking the mounting frame and the 1/8" back panel itself to see what's up!
