Restored ADS L690 floor-standing loudspeakersBlack PVC laminate cabinet finishSequential serial numbers31 height x 9½ width x 10? depth Original drivers were rebuilt by Richard So:- New tweeter domes, ferro-fluid replaced- New woofer spiders; metal frame rust removed and frames refinished - Cabinets were cleaned and are in exceptional condition, given their age- Speaker bottoms refinished back to black- Upgraded woofer gaskets installed in cabinet cutouts- Rectangular rubber grill bumpers (usually missing) and ADS badges are attached and intact- Black perforated metal grills are free of dents and scratches and original backing fabric is intact The grills and fabric are fragile.They were carefully dusted and vacuumed, but left in original condition. Trapped dust, particle accumulation and several holes are visible on the fabric, primarily along the bottom third. Oxidation and paint wear is visible around the perforated grill hole edges, primarily along side folds and bottom third.I attempted to overemphasize this in the last three photos taken in direct window light.

Offered for your consideration is a pair of ADS part number 501-0078 two-way crossover networks removed from my ADS L690 tower speakers, USA-manufactured in 1986. These crossovers divided 8” woofers from 1” dome tweeters at 2kHz.Please see my large photos and read the remaining description to decide if these outstanding dividing networks should be yours. This pair of ADS L690 crossovers is in clean, excellent condition. The large plastic mounting plates have no cracks, chips, or scratches. They feature heavily wound copper inductors, high quality resistors and capacitors, and were recently tested to function perfectly with the factory drivers. In addition, they have sturdy +/- binding post terminals that can accommodate banana plugs, pins, and large gauge raw wire. Also, everything’s clearly marked on the boards and I neatly bound the wires for the new owner’s convenience upon delivery. Overall, these ADS crossovers are very well preserved. These are a nice find if the crossovers on your L690’s, or other suitable model, have a broken input terminal or other issue. Or, they’re ready for action in your next two-way speaker building project—the faceplates measure 4?” x 4”, would require a 3?” x 3” cabinet cutout, and the product decals appear to be removable.So, as pictured and described, this pair of ADS two-way crossover networks is offered at a competitive price. Terms of Sale:I encourage interested parties to ask any questions they may have about this listing before committing to purchase. Payment is due at checkout by PayPal or other accepted methods. U.S. mailing addresses will pay $11.95 for very carefully packed shipping via U.S. Postal Service, FedEx, or UPS with tracking and delivery confirmation. International purchases accepted only from those who are able to pay with PayPal, including shipping by U.S. Postal Service First Class Parcel Air Mail. Thanks for looking!
