Dynaudio M3A Professional Studio Monitors. (yes, these are pictures of the actual speakers for sale, not stock photos...and I don't know why the one picture is sideways, but it is...) These are amazing studio speakers! One of the top studio monitors, used in hundreds of high-end studios around the world. Extremely high quality, very accurate and comfortable to listen to for hours on end - and they reveal everything in the mix with surgical precision. Other than some scratches/rash (from being in-wall) they are in excellent condition. (Just to give you and idea, the current version of these speakers (the M3ve) list price is $27,300) Comes with an extra back up spare 12" woofer that I have stored in a box. Also, if you'd like a great Amp to drive them, I have a Bryston 4B I'll include for an additional $400.

Here's the specs on the Dynaudio M3:

Dynaudio Professional M3
Designed for continuous high power operation in professional studios, the M3 represents the fruit of a research and development program aimed at elevating main monitors. A pair of 300mm bass drivers are perfectly complemented by two 150mm piston midrange drivers employing massive 75mm coils. High frequencies are accommodated by a high power version of the 28mm ESOTAR T-330 DA dome tweeter, which enjoys a reputation as the finest dome tweeter available. All drivers are ferrofluid cooled, a benefit only made possible on low frequency drivers by the use of custom designed ferrofluid compounds applied to very tightly tolerated voice coil gaps - a feature absolutely unique to Dynaudio Acoustics.

The result is a very clean, dynamic and powerful speaker in which common problems, such as cone break up, thermal compression and phase misalignment have been almost eliminated. Frequency response is full and flat, and the overall transparency of sound leaves no doubt that the M3 truly advances the art of monitoring at high levels without sacrificing quality at more relaxing volume.

Levels from 85 to 120dBA exhibit essentially identical timbre allowing total confidence in mix decisions regardless of monitoring level.

Unique linear phase and frequency response.

Every monitor matched to any other monitor within +/- 1.5dB.

28mm ESOTAR soft dome tweeter with aluminum voice coil.

Dual 150mm magnesium silicate impregnated polypropylene (MSP) midrange drivers with 75mm voice coils.

Dual 300mm polypropylene bass drivers with exceptionally large 100mm aluminum voice coils, offering dramatic improvements in power handling, bass response and distortion figures over conventional systems.

Gold plated professional binding posts accepting heavy-gauge speaker cable.

Heavy internal damping for minimum cabinet resonance.

Thermal protection of the tweeter.
