Thanks....I've learned to go a little slower and do things right the first time. Most important is the prep, whether it's cutting, gluing, or explaining why I need another speaker cab in the garage....

It doesn't take a lot of glue. I just dabbed it carefully until it was covered with a light coat...then gooped up the back of the joint really good.

Sometimes it just happens. I wasn't planning on building any SLA's, but as I was working on some other project one day, I looked over at some ply that was sitting against the wall and thought "Those look like SLA's". You start chipping away at it and soon you see that all those SLA parts where there all along. Well you got the parts, you might as well put em together. Anyway, if someone else is not so sure what you are up to, just turn them baffle up and say it's a window flower pot holder prototype.

Gotta say thanks to Seth for uncovering a bit of a flaw in my plans....seems as though the plate amp has a built-in passive high pass filter that won't let you drop below 1khz. That totally negates the plan of using the amp to run the sub. So, there will be a little research to see if that can be eliminated.

If not, looks like it will be a passive SLA. Guess it's on hold until I can get a good answer. If the amp goes back to PE, then I'll need to cut a new back and proceed with the build. This is definitely a let-down. But, it would have been worse if I had buttoned it all up and then found out it wouldn't work.

Thanks again Seth....

Bruce, FWIW I used this sealant from Home Depot to seal up the rear chambers of my tweeter assemblies. Most general-purpose silicone types don't bond well to ABS.

Yeah... sorry to be the bearer of bad news. Better to find out now than having to scratch your head and troubleshoot it when it's all assembled.

It would be awesome if there was simply a capacitor that you could bypass with a short jumper or little solder across the pads on a circuit board... and if the software/firmware end of the DSP allows crossover points below the 1kHz threshold. Fingers crossed that it's a viable solution and that it's that simple

If it's unable to be modified, you could still use it and have the SLA be powered and bi-amped. Would just need another amp for the sub if used... which you could buy a plate amp for.

I've never sealed around edges like that..... what's the reason for doing that?

Yeah, that would defeat the whole reason for using a plate amp in the first place.....like you said, I'd still have to have another amp - so I might as well just keep using the passive crossover in the T24 along with my amp bag that has a light Crown and an EQ.....

Hopefully, I can get some kind of answers tomorrow.....not even sure where to start. Need to do some googling of Dayton's contact info.

Got some wiring out of the way.....

I don't worry much about aesthetics when it comes to crossover that are hidden. Lots of hot glue, but not zip ties as this will sit on the bottom panel....should be fine.
Wired up the tweeter array.
Nothing left to do until I get a final yes or no on whether I can use the Dayton amp....well, and wait for the drivers to come in - and who knows when that will be. I had no idea that driver was so popular.

More likely Eminence has cut back production due to Covid. They were completely shut down for a while in the spring.

Peace of mind. To avoid the chance of any air leaking past the fitment between the phase plugs and horn lenses.

Actually, they are back and building - the problem is that they can't get the parts they need from their suppliers. He said it would probably be a month to get the Alpha 6s. Hope that's all it is....

I would think that's Covid related as well.

Absolutely. I think he said that a lot of the parts come from Wisconsin and they are pretty shut down - so production for the supplier is a trickle...

And it only takes one missing part to hold everything up.

Interesting......I called Dayton Audio and when you select to go to support - it takes you to Part Express. Turns out they are the same outfit. The guy on the phone used the term "sister" company.

Anyway, he understood the problem I have with the amp and he's gonna' talk to the tech people and see if there is a fix or workaround. Interesting that he said this was the second call about this in the last few days.

Supposed to get back with me later today.

I will say that I've only had to contact PE twice and both times they have been very accommodating and helpful. Good company....
