Velodyne 3/4" cloth dome tweeter from the Classic Home Theater (CHT)System $3.95 ea.

Crossover for the Velodyne Classic Home Theater MTM. $19.95 a pair.

VELODYNE -- 80-CTHT1 -- 4 1/2" x 4 1/2" PAIR 8ohms --- $18.95

These midbass units were used in the Velodyne Classic Home Theatre (CHT) system.

 

We have sold out of the 4 ohm woofer. The 8 ohm version is designed for an MTM speaker that can be used either as a center channel when it is laying on it's side or as book shelf speaker when placed in classic D'Applito configuration. We have a version of the crossover (listed above)for that application.

 

Here is a link to a review of this system.

 

CERWIN VEGA 1 1/8" Soft Dome Tweeter

CERWIN VEGA 3 7/8" Soft Dome Tweeter
Model # AT 2570B
Part Number LSETH2100
4 OHM
Price $19.95 Pair

This is the 12 inch subwoofer from the Cerwin Vega V-12S subwoofer system. It is a 4 Ohm 12" woofer. It is designed for a 2.4 cubic ft ported enclosure. We recommend a round port 3" diameter x 1.75" long. The Cerwin Vega Amp that powered the origional system was rated at 100 watts RMS. We recommend the Apex Jr MS 8A plate amp to go along with this woofer but our more powerful amps will also work. We are selling these for $22.00 each.

Here is a link to the origional users manual. Here are a couple of reviews of the system.

Cerwin Vega SL-28 Woofer $22.00 ea

This is a 4 Ohm 8" Aluminum Cast Frame Speaker that was used by CV in the SL-28 tower speaker. It is designed for a ported enclosue of .92 cubic feet. The SL-28 used 2 of these drivers in a TMM configeration in a 1.85 cubic foot enclosure. We recommend a port size of 3" diameter x 8" length for a single driver and 3" x 3" in a cabinet with 2 drivers. We recommend a 100 - 150 watt amp for this driver. Consider the Apex Jr C-6 amp.Cerwin Vega rated this driver to go down to 35hz so this would make a great sub!

This driver was used in the Rockford Fosgate R300-10 car subwoofer. You can still find them for sale if you do a search. The system used a 1.3 cubic foot sealed enclosure with a 300 watt RMS amplifier. Reviews are very positive for this unit. This is a great sub for people who need some extra bass in the car, but don't have a lot of space for a big box.

Customer Comment

"This tweeter measures very well and is by far the most dynamic non-horn-loaded tweeter that I have encountered thus far with whopping 96db@1m/2.83v senitivity coupled with excellent power handling and best used with a 3Khz crossover." Steve Sedmak
