New Matrix Q12A FRFR Active Monitors

Eminence? What about Celestion? If you are able to design a crossover... But seriously: It's not just building a speaker into a (wrong) cab and power it with an amp.

Hi folks,

just read some reviews about the new Matrix Q12A monitors. Sounds pretty interesting but I am wondering why it is so expensive (999 Euro).

What would happen if I would install the same Eminence speaker as used in the Matrix in a Palmer empty cab and drive it with a e.g., Rocktron Velocity? Would you expect a big difference? Anybody with experience here? The proposed solution would be around 700 Euros for a stereo set instead of 2000 Euro. Or is the magic on the cab design or power amp. From my understanding it should be as neutral as possible.

Any thoughts?

Thanks and cheers

Neutral isn't easy to achieve - there's a lot of physics involved, accuracy is crucial and tools are required.
PAs are not as particular, but you'll need either a weaker PA or a higher-rated speaker to compensate for component tolerances.

So, in short, not practical. Not for hi-fi, anyway.

With A LOT of time and research, it is possible for a person to build HiFi quality cabinets from off the shelf components, but, you would be happier in the long run buying a used gear 700 solution. It would have been much more new, and will keep its value (homemade used gear has NO value).

Q12A is equipped with a Celestion speaker and sounds wonderfull

I think it looks like they're using a Celestion TF1225CX driver (£182 from here http://www.bluearan.co.uk/index.php?id=CELTF1225CX8) in what looks to be a pretty simple cab.
I would have thought it would be quite simple to knock up a suitable crossover and have a passive cab version for about £250?
The new Mackie DLM12 http://www.dv247.com/pa-systems-and…CFYPd4AodWXkA7A uses a Celestion coax driver and i bet its very similar, if not the same one?

Yes, vented cab.

Like I said, if you want to put the research time in, you can end up with good results

Fortunately, Celestion includes the information needed to find (or build) the best possible cabinet in the specifications:

Small Signal Parameters:

BI: 16.08Tm
Cms: 0.10mm/N
D: 0.26m/0.24in
Fs: 71.4Hz
Le (at 1kHz): 0.23mH
Mmd: 42.76g/1.51oz
Mms: 49.68g/1.75oz
Qes: 0.480
Qms: 3.824
Qts: 0.426
Re: 5.57 ohms
Rms: 5.83kg/s
Vas: 39.91lt/1.41ft3

If you have the knowledge and time you can achieve good results. Designing the measurement of the cabinet is not rocket sience. The more difficult, or time consuming, is tweaking of the Xover. But if you know what you are doing with the wright equipement it is do-able.

Have fun!

I agree. You have the benefit of "matched component" woofer and tweeter. It can be done.

I've a pair of Q12A and very happy with them
i can use again my Axis with his piezo or play with my electro acoustic and all my electric guitar thru the kemper and Q12A and nothing else ....great !

i love the sound quality ( i've owned a Matrix GT1000 some month ago ..and love it too)
