Vienna Acoustics Mozart Grand Upgrade Kit (pair)

Probably the most dramatic upgrade kit we’ve ever done, this kit includes all of the crossover parts, as well as four M-130 Woofers and four adapter rings to replace the stock woofers and take this speaker far beyond the limitations of it’s stock performance.

You also have the choice of using budget polycaps with bypass caps or full Sonicaps ($93) in the tweeter circuit.
