The best place for a plate amp is in a box placed as close as possible to your AVR. Long interconnect wires are prone to ground loop noise, long speaker wires are not. If by 'the opening' you mean the horn mouth don't put anything in there.

They're not supposed to. DR200 is intended for small to medium venues, where wide dispersion is more important than long throw. Horses for courses.

It wouldn't be impossible, but it wouldn't be easy either. I wouldn't consider it.

They should work well with anything, due to the very low THD. Direct radiating subs can produce a lot of harmonics that don't play nice with mains, as well as making them directionally locatable.

No worries, it's too slight to have much effect.

2026 isn't off to a good start.

There are plenty of DIY forums with HornResp sections, for those who want to design their own. Our purpose is to provide plans to those who don't want to design their own.

The Qes is way too high for horn loading.

Looks OK to me.

The best thing about 2025 is that it's over.

No update, the statement is correct. It means there's nothing to be gained by going wider. Performance will be less if you go narrower.

Four T60 will go lower and louder.

V coupling works by making the horn path longer, the T60 horn path is long enough without it.

Cold slows curing and it also lessens expansion. One reason why urethane works so well is it expands into the pores of the wood. You want to maximize that. It cures best on a warm humid day.
