Anyone test TallBoy 15's?

In another post, Bill stated,"PAA2 use its own pink noise generator, average at least four readings, it can tell you how to set a 31 band EQ based on its results. It works very well and is simple to use."

For only $300.00 more, I can set my system up.

Have any of you tested the TallBoy 15's? It sure would help me out. The ones I built sound great; I want to make sure they are "right."

Thanks! Mark

If they sound good they are right. The O15 is a pretty flat cab, doesn't really need much correction if any.

Thanks, Bill, for your response! So there may be no reason to include the Alesis M-EQ230 in the rack for the indoor people? The fewer buttons and sliders a drummer gets to play with, the better off my stuff will be. Mark

Only for room correction, but it's true that drummers, buttons and sliders seldom go well together.

If a graphic EQ was available, would there really be any reason to have an attenuator for the tweeter?

With a typical noisy electric bass amp the attenuator would reduce HF hiss. With a quality pre and power amp not much need.

I am meeting up with mottlefeeder in a few weeks time and taking down my Omni 15. mottlefeeder has an Omni 12 and another bass player is bringing down the Omni 10 that I built (and sold to build the omni 15). The idea is mainly to have a play, chat and a coffee.... but also have a nice comparison of the little omni trio for bass backline use.

I will be taking my 31band eq/RTA and power amp with a pink noise source, mainly so we could 'see' what is going on with the omni12 output as it has sounded a little low in output in the bass end. It sounds like mottlefeeder has sorted it out now with eq, but still it will be nice to hear all 3 cabs side by side.

We will more than likely 'measure' the output of all three cabs so we can see the typical response curve. I plan on taking photos of the RTA response curve with pink noise, (although keep in mind that this will be indoors in a fairly large room). I am not interested in trying to measure the SPL...but any significant difference in level will be commented on.

More importantly to the bass players out there, I will try and record the sound bites on a direct A/B/C comparison with the same amp, bass, and eq as I did with previous DR/Omni cabs..

The omni 10

Built as the wide body version and loaded with 2 neo 2510 drivers and a 10bank melded piezo array in the top half.

The Omni 12
(cab on the far left of this photo)

Built with a 3 way crossover, with a 1" comp horn, 8" mid and 12" woofer (The HF horn is switchable on/off).

The Omni 15

Built with a 2 way crossover running '3 way' with an 8 bank melded piezo array, 8" mid, and neo 3015 woofer (the piezo array takes over where the 8" mid acoustically starts to drop off).

If anybody wants us to try anything specific let us know before hand. I don't expect the smaller top end of the Omni10 and Omni 15 to be enough for full top end flat response, but as I say these have been built for bass backline not PA applications, and for that role the top end is spot on.

Testing of a commercial cab as a control would be nice. If that's possible testing at both on axis and 45 degrees off-axis would be helpful. If there's anything that really separates us from the pack it's the off-axis response.

It would be interesting to see the difference in the piezo array vs. the CD horn.
