Klipsch ProMedia 4.1 v. 2-400 Parts Upgrade Kit Computer Speakers Repair Install

Klipsch ProMedia 4.1 v. 2-400 Parts Upgrade Kit: Condition is New.

The 400 watt Klipsch ProMedia 4.1 and earlier v. 2-400 computer speaker system remains popular with owners for its clarity and power. After years of use, though, a number of components will have degraded from heat.

This kit addresses the common components most likely to degrade (apart from the 6.5 speakers: note two paragraphs down). Nine components are for the amplifier panel and four are for the control pod. My source for the nylon standoffs (circuit board spacers) changed, so the replacement standoffs mount differently. (One is a push-through; the other side attaches with a plastic screw).

Included with the kit are Kester solder, instructions and photos of the component location. A new Zener diode is mounted above the board to stay cooler. Three 3-watt resistors replace lower wattage originals. Two new ICs with 8-pin sockets for 4.1 version, but not needed for v. 2-400 version and new main and rear/surround volume control potentiometers are for the preamplifier volume control pod.

This is a good time to remove the grills from the subwoofer's 6.5 speakers to check their condition. The foam surrounds degrade after 10-20 years.

They become weak, and eventually crumble. I usually have new rubber surrounds in stock. No other speaker brand matches the impedance of Klipsch's originals.

Different impedance means either damage to amplifier (too low impedance) or loss of power (impedance too high). I also may have new original Klipsch speakers on hand, as well as Klipsch originals with new rubber surrounds already installed.
