I purchased a pair of SDA-1B's on 2-23-87. They were an upgrade from a pair of Monitor 10B's. I sold the 10B's in 2001.

A few months later, Polk came out with the new, improved, and much better looking SDA-1C. Regrettably, there was no speaker trade-in policy at the dealer.:mad:

I called Polk and asked if I could buy the cabinets separately. The answer was yes, and that the charge would be $700. The nice customer service man suggested that I might consider removing the drivers and taking them to a cabinet shop to be refinished int the style of the SDA 1C's. He also transferred me to a Polk technician who suggested some crossover parts improvements I could make. Fortunately, I was handy with both woodworking tools and a soldering iron. This marked the beginning of my speaker modification practices.:cool:

Gloss black "Mirrorflex" panels were ordered from a local cabinet shop and applied to both sides of each speaker. The crossover components were upgraded with Solen polypropylene capacitors and Mills MRA1-12 wire-wound resistors. I rewired one speaker with heavier gauge speaker wire, but I didn't hear a difference, therefore I went back to the stock wire.

The grille cloths were replaced with a lighter, better quality fabric.

Oak end caps for the tops and bottoms were made at a local cabinet shop to my specifications. The cost of the crossover parts was $213 and the cost of the cabinet refinishing materials was $124, making a total of $337.

Sixteen years later and still going strong. The modified 1B's are now used in my master bedroom system. I have often thought about selling them (especially now that I have two pairs of SDA 1C's in storage), but I can't seem to part with them. I must admit though, that a gorgeous pair of LSi15's would look real nice in my bedroom.;)

    They look great, if I could score some 1b's down the road I may try and do the same thing.................just all depends on money and time.

    I've had a set of SDA-2As since I bought them new in May 87. The dealer also had a set of the soon to be discontinued SDA-1As, but didn't have any 1Bs. I've enjoyed my 2As, but have always wanted a set of 1Bs or Cs.

    Good work on your cabinets - they look great!
