The APT 80 and APT 200 use the same driver, the horn is different. The APT 80 has smoother response.

That sounds to me to be more of a compressor than a limiter. I'd take the advice to reduce the threshold by 5 to 10 volts to account for that.

Just to clarify (the plans aren’t very specific on this)...

The Sketchup is.

They weren't always the same price.

TLAH has more drivers, so it's more sensitive and goes louder. But both are home theater/hi-fi speakers. 'Multiple locations and purposes' usually means pro-sound.

Call or email Eminence.

Don't bother with the extension, it would have to be almost as large as the THT itself to have any meaningful effect.

When the RTA shows a major dip in the lows it's usually caused by boundary reflection sourced nulls, which can be created by both the speaker placement and the mic placement. You should never try to fill a dip more than 6dB deep with EQ. You have to fix the cause, not the symptom.

When you use distortion there's a huge boost in the level of harmonics, on the order of 10dB and more. If you had speakers capable of handling that tenfold increase in high frequency content, which most tweeters won't anyway, it would sound as pleasing as fingernails on a blackboard. The advantage t...

The most critical aspect with a rental is that the electronics are inaccessible. They can run the mixer, but that's it. If they're able to mess with the processing and amps they will.

That damage can only occur via abuse. It probably happened during a previous gig. With the cone shredded the impedance of the cab will drop way down, so that 56v isn't 425 watts, it might be twice that or more, explaining the clipping.

No cab that extends much higher than 5kHz is going to sound good with distortion. That's why you never see guitar cabs that use tweeters or even midranges, and why twelves that drop like a stone above 5kHz remain the preferred guitar drivers.

A and C are the best options. In A a foot to two feet from the corner is OK. B is out.

That driver will work fine, the main difference between it and a 3012HO is it doesn't have rising midrange response above 2kHz. If you are building with a tweeter that won't matter so much, as the tweeter is responsible for above 2kHz anyway. If you're only using woofers it's not going to have the m...

We need proof of purchase for a plans update. The THT is not designed to use an eighteen, which might explain why it doesn't sound right, but since the THT extends over an octave lower than the T18 that would make a huge difference as well.
