Excellent. I'm milling around, stumbling and quite unsure if I should attempt the epoxy coat this time of year or, wait until spring. One thing in my favor out here in the sticks is there's no dust in the winter. It's just not real warm.

Raka arrived today. no smell. I'm going to do this indoors.

Danny, I'm impressed. Just flipped a few switches and spun a few knobs, in the right direction or not, these filled a void in my system I didn't know I was missing. Can't wait for the top half to arrive.

don't be afraid to play with the settings on the A370's.

And here's a drawing from @Throwback you can make copies of to help keep track of your settings and what changes they make if need be

Thanks. Quite a few different senarios.

Yes there are..... try not to change too much at any one time. If you do too much, you won't know what is doing what

I'm thinking I like fast roll-off. Crisp & clean. Doesn't linger

That’s where the 80Hz/24 and 50Hz/24 low pass settings come in. These settings add an additional 12dB per octave filter at 80Hz and 50Hz respevtively.

All the setting options on these amps can be a bit daunting but they give you the flexibility to dial in the sound you want. You have to supply the patience and tenacity to keep experimenting until you get the sound where you want it. Or as close as your room will allow.

I would also recommend moving the subs towards the inside. My Mini Stratas sounded a lot better spread out and toed in.

The epoxy won't cure in cold temps. 6oF is min. but it will take a long time to cure. I don't like to use epoxy below 75F. To help accelerate cure, pre-warm the MDF boxes with a portable heater, and put your jugs of epoxy/hardener in a pan of hot water to raise the temp of the epoxy. It will flow easier. Don't do any sanding indoors, especially before epoxy is fully cured which takes a week or more (depending on temp). You don't want uncured epoxy dust in your lungs!

Thanks. This set-up is so temporary. By Monday-Tuesday I'll have the wedgies on top and the Voxativ's in our bedroom.

Thanks for this. The epoxy application is on hold until springtime. I may muster up the ball's and try my hand at veneer. What's stopping me? Ruining a few hundred dollars worth of materials and making a real mess of things.

A set of quads built from our modular design. These were sprayed in a satin white lacquer. Will load up the 2nd cabinet this weekend and get them wired up.

Hi folks. I have an issue I can't seem to solve. When I power up the second amp there's a high-frequency whine I that won't go away. Doesn't matter which amp I power first it's always the second one. Thanks

edit: issue solved. servo connections were inverted.

HAL · « **Reply #459 on:** 24 Jan 2019, 01:53 am »

So both A370 amps whine, just depends on which one you start as #2?
