Kal, will do !! Thanks,
Stephen, non of the drivers used from any tower speaker mfgs (skylon, wetsound, and nvs) compare to the Beyma 8g40 or the Selenium 210 TI. It is so incredibly clean... The only drawback is the weight and the cost of the 8G40. The Beyma weighs approx 7lb and cost $160... The 210 hlcd is pretty reasonable at $32..
Really looking at what is available, the best bang for the buck upgrade would be to replace the crossover and the HLCD with the Selenium 2V2K/350 crossover and the 210 TI hcld. The approximate cost would be $65 - $70 a cabinet or $150 total layout (from parts express).
