These famous speakers arrived at our shop in great shape, but in need of refurbishment.

We carefully restored them to like new performance, ready to make someone happy for another 30 years.

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


First of all let's discuss the bass. These speakers are at a level of performance unmatched in our shop to date, which is really saying something! The bass is controlled, but PLENTIFUL. Just look at the size of those dual bass drivers. The smaller 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 a set of Watt Puppies 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.

The 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!

These speakers started out as the original Series I, but the original owner upgraded them to Series II at a cost of over $8,000. New Series II tags and paperwork confirm this is the case. Upgrades from I to II include replacement tweeter and crossover modifications.

Here's a list of everything we did to get them looking and working fantastic:

1. Replaced the foam baffles on all eight (!) cabinets

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

3. The 15" woofers were refurbished previously by a professional, evident by the great care and precision from their work.

4. Heavy duty casters were installed to make it actually feasible to move these around the shop (and your home).

5. Brand new grills were supplied by Wilson for all eight drivers. We didn't install them yet, as we like the look of the bass cabinets without the velcro (included in this listing).

6. Extensive testing of all drivers, crossovers, and connections to ensure proper performance.

7. 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 with your purchase is a full set of spikes, tools, and upgrade documents.

Yes we do have the panels that flank the top sections of the speakers, but we like the look without them in place. Makes them look a bit more industrial and less 1990's.

MSRP was around $75k back in the day! Here's your chance to own these legends for 1/3 of the price.

These are available to ship worldwide via custom crates made by our local Craters & Freighters. Please inquire for a quote on shipping and packing.

We'll deliver these for free for local sales within 100 miles of our zip code 07452. You'll just need to provide two or three able-bodied people at your end to unload as these monsters are about 600 lbs each!

And we can crate and deliver these anywhere in the USA for $1,200.
