High End Center Channel Kit 6.5" ESS Woofers Cerwin Vega Horn Tweeter 2 Way Design

6.5" Center Channel Speaker Kit
 

• 6 1/2" ESS Woofers
• Cerwin Vega Horn Tweeter
• 12 dB 2 Way Crossover

Had requests for a 6.5" center channel kit, so we went into stock to see what we could come up with.

The result is a kit that supplies. A crisp clean sound, it has tight bass, a warm mid range, clear precise highs, plus good power handling capacity.

Went with ESS Labs,. it is a very nice 6 1/2" woofer with a very large magnet structure. It has a 1 1/2" voice coil,  it will handle some power.

Next,  a killer tweeter, selected a Cerwin Vega Horn. They are very good, clean crisp highs and a good range to keep the middle coming at you.

To tie them together we include our Mavin 12 dB two way crossover, it's crossover point is very well matched to the range of the speakers in the kit.

The object was to come up with a nice little center channel, or book shelf / floor tower speaker. With a range of about 35 Hz. to 20 kHz. plus, and a power range of 5 to 150 watts at 8 ohms. With this kit, we did that exactly.

You wire the woofers in Series in order to get the required 8 ohm load.
