Tannoy AMS 10A RARE Vintage 1990s Powered Professional Studio Monitors Speakers - Amazing sound!

This is a very rare studio monitor pair from Tannoy.  Released sometime in the early '90s, they were expensive when introduced - something like $5,000/pair.

It's hard to find much info on these; not sure that Tannoy built many of them, possibly because of the price.  I believe they also made these in 8" and 12" models; this one has a 10" speaker with concentric tweeter.

Even though I used these along with two other sets of monitors when I engineered/mixed full time, this is the set I always used to play mixes for artists and label heads.  I mixed so many albums on these, including quite a few hits.  I just don't have the need or space for them anymore now that I'm mostly retired.  Although this pair got used a lot, I never mixed very loudly so the speakers/amps were never stressed.  They show some scuffs and scratches, but nothing too serious and nothing that affects their operation.

I'll have these professionally packed, insured, and shipped.  They are very heavy - 55lbs each - so the shipping is pricey.

These are beautifully self-powered, with quite a few parameters set from the rear panel, as shown in the photos.  The concentric speaker/tweeter combo makes for great, phase-accurate imaging.

Here's some info I found from an old listing of an 8" pair.  I used to also have a pair of the 8" version, and they didn't sound nearly as good as the 10" model, but I believe much of what is said here applies to the whole AMS series:

"8" powered reference monitors. Flat clear sound. Time aligned high frequency driver.

8-inch dual-concentric low-frequency driver concentrically mounted to a 1-inch HF compression driver with a damped tulip-shaped waveguide. The drive unit is housed in a charcoal-grey, slat-side inlay, inert DMT (Differential Material Technology), front-ported cabinet. The twin laminated, space-frame design of the cabinet is heavily braced and decoupled to prevent signal coloration. All contoured cabinet edges feature isolation pads for added durability. The quoted frequency response is 38 to 25k Hz, ±2.5 dB.

The bi-amped MOSFET power modules deliver 140 watts continuous to each of the HF and LF sections. The amp's construction techniques and components are reminiscent of high-end audiophile amps. Heat is dissipated via the massive double-anodized, aluminum-finned back plate. A blue LED on each cabinet's front panel indicates power on.

The layout on the back of the amplifier plate is well marked and easily followed, and the switches allow for easy adjustment access. Operating voltage is switchable between 100 and 120V and 200 to 240V.

The active circuitry in the crossovers utilizes high-grade, 1% precision-matched components yielding tolerances within 0.25 dB throughout each passband. The sophisticated active crossover shaping and design produces not only a tight amplitude response, but also linear phase response."
