These are the HiFi frankenshorties built from the other SLA, they look weird, but sound nice! Crossed at 5.5k 3rd BW with Jantzen filters, I fumbled around for a while with impedance, though settled on 16ohms, the drivers are 8ohm series wired Jaycar 6.5" Hifi/GT302 tweets with an 8ohm resistor paralleled on the tweet filter output (cheater, yea..), the sub is a 28" Lab15 T30, powered by an ancient Pioneer receiver with a 200w Sure HiFi D amp for the T30. One day I'll fit a second top hat for a safer spiral array if they go outside, they do well in the Billiards room. That AT sitting there, is that affecting LF output just by being in the room? I ask as the next room over has the second T30, and a LAB15 THT also in the same room, not using them together though, one system is HT, the other at my work desk for 2.1 sound.

It could be mate, this was bought through Sure though, the AA-AB31243

The input attenuator works well, auto standby. Its turned -13 detents to be balanced for my liking

It is. In effect it's a bass trap.

Move it to cover the mouth: either face down on the floor or flush to the wall. Or remove it completely.

Or, leave it there......it might help the sound of the low end. Lots of money gets spent in studios on bass traps. You have a free one there. Move it around so see where it helps the most.....or, if it sounds good, leave it right there.

Roger that, thank you!

It's face down atm, but..

That sounds like a cool exercise! Could I market the AT to the HiFi crowd :P , what would you call it..? A "Passive Horn Bass Trap"..? I could fit speaker spikes and gold plated corners :lol:

Thank you for the responses :)

Can I use one as a monitor for a drummer? Our singing drummer is going deaf and hates headphones. We borrowed a portable tower PA for practice once and I set it right by his ear. He loved it and no feedback. At shows, we blast a 12" monitor at his face, but I'm so over it. Our PA is 12" Yahama clubs & floor monitors. Would one of these designs would work well for this purpose?

At the range it's used at it a 2x6 will be plenty. But pray tell why he didn't have one of your Yammy monitors? :confused:

He does have his own 12" Yammy. I aim it at his face from a stool beside his floor tom. He keeps asking to turn it up, or move it closer, and then it becomes a fight with feedback. Mostly in tighter spaces, I guess. I'm no sound expert, btw.

I'll look into a 2x6. Thank you.

If the Yamaha isn't doing the trick, an SLA isn't going to be any better. Before you do anything, tell me this.....do you have a 15 band EQ on that monitor, or is it a digital board with available graphic or parametric EQ? If it's an analog board, you need to get an EQ in line on that monitor. If it's digital, you need to use the EQ on the Aux out. That would let get that monitor shaped properly for the right EQ to accentuate the vocal range and control the feed back.

You should be able to blow his head off with that monitor from that close. And it should be positioned on the other side as most drummers have the mic on their left and it typically is pointing a little more toward the floor tom. On the hi-hat side, there would be better rejection. Now, if he positions the mic differently, just try to get the monitor as much to the back side of that mic as possible.

BTW.....what kind of mic is he using?

We're still analog, and I got a big NO to in-ears. Hard to teach old dinosaurs new tricks. We quit carrying subs but it still sounds great both indoors and outdoors.
I have a dual 31 band eq, one channel on the tops and the other on the monitors. The drummer's monitor is powered on its own amp channel so we can crank him up, but it shares the signal coming from the eq... Thank you for the good insight! Wow, I am duh... need to put the drummer monitor onto its own eq.

We tried a LOT of dynamic mics, expensive and cheap, and he ended up taking mine, the EV ND367s. He places the mic stand on the right and walks in from the left, that's why I put the monitor on the right, behind the mic. He just told me he's willing to experiment with changes, so we're getting somewhere! :-) Thank you.

Definitely get an outboard EQ to tame that monitor. Roll off everything below 120hz or so...and everything over about 5khz. The goal is to make it sound a little honky so that it cuts through. If it's big and fat and full trying to sound like the mains, it will get buried once the band starts playing and all of those frequencies start masking those same frequencies in his monitor - making you turn it up and up and up. In other words, thin it out some. It will cut through and you'll probably have to turn it down from where it is right now.

The mic you're using is a cardioid, so the best place to position the monitor is shooting directly at the back of the mic. Hard to do that on a drum kit, but get it as close as you can.

Oh, and make sure he sings right on the mic...not 6 inches away.
