X-CS Classic

The X-CS Classic Kit

X-CS Center channel kit

With the success the X-LS design there was a strong demand for a matching center channel version. So the X-CS was created, and is now made available as a kit. The original design was released through AV123. 

The X-CS uses a pair of 16 ohm woofers in parallel to maintain an easy to drive 8 ohm impedance. This also brings the sensitivity up to 90db. The frequency response of the original samples were as good as +/-1db. So these speakers offer a very smooth and accurate response that is well above the industry standard. The tweeter is the same soft dome tweeter that is used in the X-LS Classic. The crossover is fully assembled with good quality air core inductors, polypropylene capacitors, and wire wound non-inductive resistors. Also included is a high quality OFC wire in polyethylene, binding post cup, solder, screws, and heat shrink. 

The X-CS Classic is a sealed box design and can be placed into entertainment systems or near the front wall. 

The X-CS Classic can also be built into a larger optimal ported box and used as left and right main speakers. This version was originally released as the X-MTM Classic. 

The X-MTM Classic version is a rear ported design that extends the -3db down point to 40Hz. 

So to build a pair of the X-MTM Classics just order a pair of the X-CS Classic kits with the X-MTM option. The X-MTM option adds additional wiring needed for the longer runs, two 2" ports, and a set of Brass floor spikes. The X-MTM option is an additional $25 per speaker. 

The X-CS Classic and X-MTM Classic is an incredible combination that delivers great sound with good sensitivity levels and an impedance load that any home theater receiver will have no problems driving.

Here is that same response curve on an industry standard 10db scale.

Here a very clean spectral decay can be seen. 
And here is the impedance curve pf the sealed box X-CS version. 

These are priced at $79 per speaker. They are priced individually because they are used as single center channel speakers. If you need a pair of them please order two units.
