It will work fine.

Fancy cables and expensive amplifiers are pointless, the loudspeaker is the weakest link. (now let me put on my fire suit...)

P.S. I've heard the CBT24 and I posted the thread that wesayso referenced. So I'm not being a COMPLETE troll, just a small time troll

I would like to do something more affordable but also oriented as well to Home Cinema needs.
Here are the points where i'm not really clear and would like to get your inputs:
- anyone has had good experience with line array speakers in home theater configuration? if yes:
- my system will be driven by an EMOTIVA XMC-1 pre-amp
- main speakers would be the CBT24
- Sealed Subs would be one size smaller: Dayton Audio Ultimax on 15"
I'm now looking for help on these points:
- Do i need a DSP per channel or the XMC-1 with its dirac LIVE would be enough?
- which Class D power amps with (or without) DSP would be good to drive both sub & line array speaker in each side? ideally one Amp to drive both Full range & sub?
- which would be the best central & rear speakers DIY speakers to accompany these main speakers? smaller vers of line array speakers?
- which power amplifier would be good for these 3 other speakers?

Thanks!
Prestige?

Be aware that the measurements in that review are flawed. They didn't measure correctly.

There were also several wrong facts in the review and they guy who listened didn't even use measurements with integrating a subwoofer. It confirmed all my negative bias towards hifi reviewers.

Anyway, here are proper measurements of the CBT24. Both raw without EQ and one with EQ. Take notice that the resolution of the Y axis is high with 3 dB increments. Measurements were conducted over a reflective floor in a normal room, meaning room modes are included.

Ok - that's what I thought. Dirac should be capable of providing the equalization that you'll need for the CBT-24. If you bi-amp there are many amps that will work fine depending on your budget. The MiniDSP plate amps are a good option.

As far as a center and surrounds that depends on the coverage you need and how much output is desired. Smaller arrays are possible but with a 2.5" driver they become very limited. If you room allows a horizontal CBT array works great as a center channel. I prefer 2-way CBT designs but your budget might not allow that. A conventional center channel with output capability comparable to your arrays is probably more practical. The same is true for the surrounds.

Bjorn,

Don Keele sent me a copy of the review. Before you jump on the reviewer (which overall was favorable towards the design) you may want to reconsider a few things.

It's possible the MiniDSP settings were not correct as supplied to the reviewer (different measured transfer function). These are probably the easiest speaker of any to measure. If the transfer function is wrong then that may be the major factor. There could also be QC problems, such as wrong wiring / shading, out of spec drivers, etc. (hopefully not).

Whether it's a hard surface or carpeted the response curves won't vary that much. If they did, then they would be supplying different presets for the type of room being used.

A horizontal off-axis curve would've been nice and more informative.

It depends on what your system goals are.
