Wilson Audio X-1 Grand SLAMM Flagship Speakers - Restored

Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

These famous speakers arrived at our shop in decent shape but in dire need of some TLC. We carefully restored them to like new performance and now they're ready to make someone happy for another 30 years.

We realize that most audiophiles change speakers much more frequently than three decades, but we suspect due to their performance and enormity it won't happen that often with these!

Fist of all let's discuss the bass... These speakers are at a level of performance unmatched in this shop to date. The bass is controlled but PLENTIFUL. Just look at the size of those dual bass drivers. The small ones are 12" and the larger ones are 15", enough to rattle the windows in your home.

The mids and highs are comparable in character to let's say a set of Watt Puppys from the same era - perhaps a model V or VI but with a much wider soundstage, facilitated by the use of not one but TWO rear facing tweeters in EACH speaker.

Construction quality is ridiculous. The cabinets are made out of some crazy material developed by Wilson, and the woofers feature magnet assemblies almost as big as the cones.

Here is a list of what we did to get them looking and working so beautifully:

1. Replaced foam baffles on all EIGHT cabinets

2. Replaced the foam surrounds on the 12" Woofers utilizing the best techniques and materials. The dust caps were removed and the coil assemblies were centered using shims. Sure this process takes forever - but yields factory-like results.

3. The 15" woofers were restored by someone previous with great care and precision.

4. Installed heavy-duty casters to make it feasible to move around our shop (and your listening room).

5. Touched up a few spots in need of attention, mostly around the lower lip of the bass cabinet were you are likely to bump into things.

6. Installed brand new grills supplied direct from Wilson for all eight drivers. Actually, we didn't install them yet as we like the look of the bass cabinets without the velcro (which is included in the sale).

7. Tested all drivers, crossovers and connections to ensure proper performance.

8. Extensive listening utilizing our Jadis 20W reference system. Yes 20W (!) is enough power to drive these speakers with authority, making them a dream speaker for those who like single ended amplifiers.

Included in the sale is a Wilson X1 brochure and all of the grills. We also have the panels that flank the top sections of the speakers, but like the look without them in place. Makes them look a bit more industrial and less 1990's.

MSRP was around $65k back in the day ($103k in 2020)... Here's your chance to own these legends for 1/3 of their original price.
