The driver can be upgraded to the Walsh 2000 which allows for the bass to be extended down and the treble to have wider dispersion. All necessary parts can be installed with a screwdriver and takes only 10 minutes. The upgrade comes with a 3 Year Limited Parts & Labor Warranty, assuring you of years of listening pleasure.

Harold T. says, "I just wanted to let you know the speaker upgrade installation went perfectly without any problems.  The 100 Mk-2 cabinets still look great with the Walsh 2000 drivers installed.

"Their sound has taken my system to a new higher level on every recording I have listened to thus far. I have spent hours just listening with amazement. The increase in detail, expansion of soundstage, and increased stereo imaging is truly hard to believe. Many recordings, that I've had for years, I feel as though I'm hearing what the artist intended for the first time.  It's almost like I have been looking through a dirty window for years and when cleaned, the colors are brighter and sharper than I ever could have imagined."
