RBH C-88SW

This is an in-wall (built-in) non powered subwoofer used by me some years back in a home theater system.  This system was put together by me prior to the advent of AVR units.  So what I did was obtain a processor from the TV provider that offered 5.1 surround sound.  I used independent stereo power amps to drive all channels including the one connected to this subwoofer.  Note the spec sheet attached from the company.  I am the original purchaser/owner of this speaker. The unit never was installed or built into a wall.  It was placed behind an equipment cabinet and worked perfectly. The unit has a grill that attaches to the front of the speaker.   As I moved to a new home this original system including the subwoofer was not compatible with the new environment so all was placed in storage with the intent of using it at a later time.   It is now time to move again, so I have put everything up for sale with the  subwoofer being the  last piece to be sold.  The reason for the 7/10 rating as to condition is the age of the unit.  This unit sold new for $450.00  The unit is in perfect working condition.  I will pay freight/shipping in continental US if unit is sold at asking price.
