I think the crossover works. The cabinet has some wood damage on a few of the corners. Needs restored. I also have the insulation. It also includes 7 of the 8 screws that hold the subwoofer in place. PLEASE look at the photos for details.

The new ORANGE Quantum Fuse is a direct result of technology Synergistic Research first developed for their Limited Edition Galileo SX PowerCell. At its core are new UEF Technologies and a completely new multi-stage high voltage treatment process for the lowest noise floor of any fuse they have ever manufactured. In fact, ORANGE is by far the most significant leap in performance across five fuse generations. Subjective improvements include better timbral accuracy where separate instruments and voices take on a new degree of life-like realism. Other benefits over prior SR fuses include a larger soundstage with greater depth, width, and front-to-back layering. Musicality or the presence of increased detail without a hint of fatigue is off the charts for extended listening that is never harsh despite being their highest resolution fuse to date. please check out my other items

Superb fuse from Synergistic Research and in excellent condition. Now surplus to requirements.

-One sold, so only one left in stock- New in box with high discount, never used! Two Synergistic Research Master audio Quantum Fuses. We took them out of the boxes for taking pictures only. They are the 5x20mm Slow-blow version, 6.3A 250V. Master Fuse is an entirely new kind of Fuse. Enter Master Fuse; the first Synergistic Research fuse developed expressly for full resolution, dynamics, soundstaging, speed, and impact without the need to create musicality as a system-wide fuse loom. Instead, they engineered Master Fuse to work alongside Purple and Orange fuses to create dramatic new levels of sonic realism, featuring wall-to-wall, floor-to-ceiling soundstaging with unparalleled resolution, dynamics, and frequency extension. Best of all, most systems will not benefit from more than one or possibly two Master Fuses in an otherwise complete loom of Purple and or Orange fuses. Retail price is 599 euro, now for 499 euro for one Master Fuse only. Check our other listings for more interesting items. Free shipping worldwide!
