Klipsch RP-600M replacement crossover kit (also RP-160M)

Description

We have started with a recommended “baseline” for components. You may select upgrades or downgrades based on your preferences.

Recommendations:

Capacitors: The excellent performance value of the JB -JPX Superior capacitor line gives upgraded performance at a very budget friendly low cost. A bypass capacitor is recommended in this position, with two options offered.

The woofer capacitor is in a shunt position and is a fairly large capacitance value. The most cost effective upgrade we could identify for this capacitor was to parallel two smaller capacitors instead of using a single larger capacitance value. Lower capacitance values are able to discharge at a much quicker rate. By pairing two smaller (and equal) capacitors instead of a single larger one, the discharge rate is improved while also doubling the power handling capacity, and the cost remains low. We have discounted the cost of the parallel pairs of capacitors which are also measured and matched at no additional cost, to obtain the desired capacitance.

Bypass capacitors: Small 0.1 uF bypass capacitors are offered from the Obbligato Copper and Silver Series . These are high-quality, fast, clean, and resolving capacitors, representing a great value at $3.50 each for the Copper Series and $4.50 each for the Silver Series.

Inductors: 16-gauge is proposed as a “baseline” for the woofer inductor but really is already a premium inductor. 14-gauge on the woofer inductor is offered as a top-tier upgrade. 18-gauge is also offered on the woofer as a downgrade for the most budget conscious.

The tweeter inductor includes an 18-ga as “baseline”. The tweeter does not benefit as much from the larger-gauge wire as the woofer does, but the lower inductance does allow for low cost upgrades if you choose that option.

Resistors: We have kept it very simple here. High-Quality resistors are very affordable. We are providing a GR-Research branded 10 watt resistor ($4 each) for the single resistance value in place on the tweeter circuit. We don’t see a need for $30 boutique or even $10 versions in this design but if you feel that need, email us and we can modify a package for you.

Wiring: These are fairly large speaker cabinets. 15ft of each color is plenty for a clean install with all new internal wiring. For those with additional projects planned, the 30ft wire option is also provided.  You may also purchase the kit without our wire.

We do think our wiring is the best value available. Premium wire without the traditional markups. Both versions are very similar, 16ga solid strand, high-purity OFC, Polyethylene insulator.  The “unbranded” is imported, the “Premium USA” version is not. Wire details are here.

Crossover boards & assembly option:

As a convenience we are offering you empty crossover boards, already sized appropriately for the size of components and cabinet. We use premium baltic birch. It is an expensive material, and not everyone wants to buy a small $30 sheet when they only need much smaller pieces. Price is $10 for the pair of custom sized boards.

Complete assembly of your crossover boards is available. A $150 assembly fee includes the the assembly labor, crossover boards, and all small incidentals (zip-ties, heat shrink as needed), as well as the additional shipping costs associated (size & weight). Assembly capacity is limited, with a 2-week maximum turnaround time, and is only offered as an add-on. For details related to our assembly services, review this link.
