Shahinian Contra-bombarde Subwoofers

One pair of Shahinian Contra-bombarde subwoofers serial numbers 54 and 55.  These are in excellent working condition.  The drivers were replaced by the original owner with units purchased directly from Shahinian Acoustics. These subs produce deeper bass than the Shahinian Double Eagles (solid down to 17Hz).  According to Richard Shahinian, the cost to produce these massive transmission line subwoofers would be astronomical today.  I have used them in conjunction with  Shahinian Diapasons using a crossover configuration specified by Richard. As can be seen by the pictures, the 6/10 rating is conservative.  I prefer to sell in the Chicago area due to their massive size.  If they don't sell after a month, I will then agree to ship to wherever. The picture with a Diapason module on top was taken to give a sense of how large these are.
