New RAD 10MKII Subwoofer
« on: April 16, 2007, 06:17:15 AM »
I wanted to introduce the new RAD 10MKII subwoofer.  This sub uses a 10" black anodized aluminum cone (Dayton RS HO version) and a 300W BASH amp in a 13" sealed cube.  The enclosure has a 1.5" thick front baffle and an internal 3/4" brace which interlocks the top, sides and bottom for a very rigid enclosure.  

The box with light stuffing approximates a Bessel alignment with a Qtc =.577.  This is a substantial increase in sound quality from the original RAD 10, which has a Qtc of .707 and also used a 150W amp.  The original was a great little sub for small HT setups, but could become a bit boomy while listening to music.  The new design gives up a little impact for HT but gives a much smoother response for 2-channel music listening.

Here are some of the features of the amp:

    * High power output in a compact, lightweight design
    * Speaker and line level inputs for connection to any stereo
    * Limiting circuit prevents audible clipping and protects woofers
    * Auto On/Off and phase reversal switch
    * Dedicated LFE input
    * 50-150Hz lowpass crossover

Initial pricing will remain the same at $600 for a completely assembled and tested unit.  The pictures below are of my demo unit with a figured cherry veneer, which is available for a $50 upgrade.  This unit is also up for sale for $500 if anyone is interested.

If anyone has any questions please don't hesitate to ask.
