Klipsch Heresy E-2 replacement crossover kit
All pricing is for a pair of crossover components. This kit uses the original E-2 Klipsch schematic, and provides you an easy pathway to upgrade to higher-performing components.
This design accommodates reuse of the single “auto transformer” from your existing speaker crossover. This component is essentially an iron-core inductor with multiple leads at different inductance values. It is expensive to replace ($150/pair) and is not an item that wears out, so therefore not recommended for unnecessary replacement. If you would like to purchase a kit that includes this replacement part, please email that request and it will be offered. We will go out of our way to support your rebuild so please email to discuss any additional options or special requests.
The default kit options start you with a recommended “baseline” for components. You may upgrade or downgrade based on your preferences.
The “Baseline” kit includes an aircore inductor on the woofer circuit, and quality bypass capacitors, with additional options available.

Description
We have started with a recommended “baseline” for components. You may select upgrades or downgrades based on your preferences.
Recommendations:
Capacitors: Our “baseline” offerings are from the JB, JSX Superior line, which offers tremendous value as do all of the JB capacitor lines. The premium offerings are from the Obbligato Copper and Silver Series.
There are two smaller in-line capacitors (tweeter and mid circuits.) Both are worthy of upgrade and should be the first priority. If budget only allows upgrade of one component, that priority should be given to these smaller capacitors.
The woofer capacitor is in a shunt position and is a comparatively larger capacitance value. Several options are provided to allow you the flexibility of aligning with your budget preferences. Upgrading this capacitor should be third in line of priority, only after having upgraded the tweeter capacitors and selected a minimum of 16ga for the inductors. Adding a bypass capacitor to this component would be a very cost effective option and will allow for faster discharge and response from this capacitor.
Note: The two smaller capacitors are originally labeled as 2uF which is a less-common value amongst many premium product lines. The more common 2.2uF value is offered in its place. This small variance is very acceptable, and is well within manufacturer tolerances. The provided capacitors will be measured and paired to ensure they are as close to 2uF as is available. In actual practice, a 2.2uF substitution that is measured and selected for being within its lower capacitance range is very likely to measure closer to the stated and desired value than the original budget 2.0 that is seen to frequently measure as high as 2.3 or 2.4.
Bypass capacitors: Small 0.1 uF bypass capacitors are offered as default for the woofer capacitor. Options 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. You may remove this option, accept the default of 1 pair (woofer only, 0.1uF bypass), or add an additional 2 pairs for the tweeter and mid circuit capacitors (0.01uF).
Inductors: A 16-gauge aircore is offered as the default recommendation, and is a premium selection. Many alternative crossover replacement options utilize an iron-core inductor or smaller wire-gauge in this position for cost-savings (higher-profit margin on a prebuilt assembly). However with consideration for the crossover point which allows the woofer to play into the mid-frequencies, an aircore inductor is the superior choice. 18-ga and 14-ga options are also available to accommodate your specific budget preferences.
note: the 18ga 4.0mH is in stock and will ship immediately. The 16-ga or 14-ga options will be custom order and will ship from the US factory within 5 to 7 days.
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 $35 sheet when they only need small pieces. Price is $15 for two pairs of custom sized boards (separate boards for woofer and tweeter circuits).
Complete assembly of your crossover boards is available. A $125 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 with the assembled boards (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.
