Crest VS series versus Crown XTI

(1/2) > >>

Jose A. Morales:
Hello board!

I'm building a custom DJ "bedroom" setup with a Xone DB:4, XDJ's, SL1200's. I'm using Infinity Kappa Perfect 900's with the 300M as a 3way setup. Yes, they are car audio speakers, which i believe are essentially near field monitors. I'm using 2 Kappa 12' woofers in a ported enclosure tuned at 30hz.
I'm using a Rockford Fosgate DSP processor for tuning, setting crossover points, and delay.
I was using a Crest VS650 for my tops and a Crest VS900 for my subs. I purchased a Crown XTI1000 to replace the VS650 hoping to upgrade the sound quality and was disappointed, the sound was harsh and lost some of the warmth of Crest.  My intention was to use the the dsp in the Crown amp and no longer use the Fosgate processor.
I understand the Crest amp is a class A/B versus the Class D Crown.

The Crest amps are quite inexpensive and I dont mind the size/weight/heat issues and using an outboard processor such as dbx DriverackPA2.

My question is, what would you recommend as an upgrade to the Crest VS series amps?

Thanks for taking the time. :)

Go back to the Crest VS650 on top and bridge the XTi 1000 for the subs.

It's a scabbed together system with leftovers, nothing wrong with that - I did a similar build for a small near field studio system.

Given the mix of components, I'd stay with the Fosgate controller to set it up for optimum performance.  If the woofers are 8 ohm the little XTi outta push them just fine bridged.

If the Fosgate controller will do 3-way, use the Crest VS900 for low mids on 900's.

That's a cost effective solution.  I use a dbx Driverack PA2 on my little studio system, went to that for ease of tuning it using WiFi & iPad.

In the end, it really depends upon how much money you want to spend on it.

Steve,

Thanks for your input.

I just ordered a PA2, I'm going to miss the dual knob setup that comes with the Fosgate processor.
I'm going to run it the way you recommended, VS650 for 3" mid and tweeter, VS900 for the 6X9's, and XTI1000 for the subs. The subs I have are selectable to either 2 or 4 ohm. Should I wire them in series to generate a 4 ohm load and then bridge the amp?

Also, I might be able to score a Crown Drivecore CDI4/300, for around $500, do you think I would get a huge improvement in sound quality on the mids and highs?

Steve-White:
Just to be sure, you have a Crown XTi 1000?  Picked up a used one?  Not an XTi 1002?

With 2-4 ohm woofers, there is no need to bridge amp.  Set them up for 4 ohm operation, wire one on each channel of the XTi 1000 and done.

Let us know how it works out.  You should like the PA2 for it's ease of setup, the control application works well and is easy to navigate through.

XTI1000
The woofers have a selectable impedance of either 2 ohms or 4 ohms.
