Yeah @eg, wu just drove the t30 to the max; as the edm listend to even somewhat profits from the unbalanced/overpowered bass. For rock music this just sounds unnatural. Another thing to add, the thermal situation i had in mind: the amp kept its temperature, the cabs as well. But i think in a warm s...

What a great post. Seems like you didn't leave a single detail out. I like it. Once you get the EQ dialed in, you should notice that you're able to play pretty much any genre without having to make level adjustments in the system itself... just on the DJ controller to taste. Although, some of the ol...

Welcome back! Bill will have to verify, but I seem to recall him saying that the phase response of the same cab, but with different drivers is generally okay to use together and that any mismatch in phase would be negligeable. I'm just going from memory, but didn't we find out that the Vd of the two...

Just a cautionary note for today, when setting your limiter, you must use a sinewave signal and it must be either a frequency that's not effected by the highpass or lowpass filter (the filter setting isn't when the filter starts working, it's the point where the signal is already -3dB or -6dB, depen...

This is exciting news! Wow, that was quick. Great job! For what it's worth, doubling cab count, assuming they're in one stack, will result in +6dB. Doubling of perceived volume, while subjective, is commonly stated as +10dB. Tripling cab count, again, sonically coupled in a single stack or stacks ri...

Without having access to the Hornresp files, I'd highly recommend using the frequencies and slopes in the plans. But, you have aparantly modeled it fairly close in Hornresp. If you haven't seen it in there, you can apply filters then check that the excursion is under control at your planned max volt...

I hope I'm wrong, but a few of them appear as though they may be too far out from the ledge. Driver screw holes are pretty close to the cutout diameter. I'd trial fit and screw down the driver before installing that panel, just to make sure the screws actually go into the retention blocks. Not a hug...

Was that trace taken with the highpass filter disabled?

If not, what frequency and slope are you using for the T30's highpass?

I never did finish my WH project. Sadly, it got tossed when I changed life direction.

That came out amazing, Keryn.
Well done!

I didn't reach that anyway...and when i see what two cabs do, i probably don't want to reach the limits with 8, at least not when i am standing too close to it :D When completed, i'll drive to a place where i can fire things up, will measure everything and tune that beasts to my will :) For now jus...

This was the right move. The difference in output between 100V and 107.5V is completely imperceivable at only 0.6dB.

That's awesome! Congrats on that little taste of completion. Everything's looking really good. Square, concentric, and uniform. Well done!

Out of curiosity, what were the first two songs you played?

Phwoar, look at that beast! Bloody oath, that’s a rip-snorter! A real ball-tearer, an absolute pearla! Flash as a rat with a gold tooth.

That'll bring the doof.

... all on a 10A circuit. Love it!

You're a deadset legend!

I've always been curious... how tough is it to get the third cab up on a stack of two. Possible to do alone?

Got any pics with someone standing next to that pile of awesomeness?

i think i had a language barrier... I don't know if you're typing this all out directly from your head or using a translation app/program. But, since you joined the forum, as written, your English is superb and your communication skills are excellent. Some of them so good, I thought to myself "...
