Tannoy System 10 DMT / DMT II
A 10-inch coaxial studio monitor built for power and precision, with a footprint no deeper than 290mm
Overview
The Tannoy System 10 DMT looks like a workhorse. Thick baffle, industrial grille, a profile that doesn't pretend to be anything but functional. The engineering under that shell is what earns a second look. It's a dual concentric monitor, so the tweeter sits at the center of the 10-inch driver and gives time-aligned sound from a single point source. It was built for accuracy, power and reliability, and clearly for real studio use, not just audiophile listening rooms. The DMT II variant keeps the same core concept but swaps the original's DMT energy controlling structure for a bass reflex enclosure. That suggests a shift toward extended low-end response, useful in larger control rooms or for music with deep content.
The System 10 series doesn't hide its size. Dimensions don't exceed 560 x 365 x 290mm, so it's a substantial standmount speaker, but the depth is restrained for a 10-inch design. That makes it viable in tighter spaces. Power handling is rated at 350W RMS, which implies it was never meant to be driven by modest amplifiers. At 8 ohms nominal it's electrically friendly, but it demands current. Because of its size and power requirements, it is often better suited for larger spaces, and its passive design means the entire signal chain defines the performance. Some forum users have compared the DMT to the classic Tannoy Cheviot, though no official lineage is documented. It was a monitor built for engineers who needed honest translation.

Collectibility & Value
There are no official production dates or original pricing, but the Tannoy System 10 DMT and DMT II have found a niche in the used market. According to current listings and user reports, a pair in good condition typically trades around $900, with some units described as "Excellent - Serviced, tested, and cleaned." A Reddit user noted buying a Gen 1 DMT pair from a former studio owner, which suggests these monitors are still valued enough to be preserved and resold. The appeal is Tannoy's coaxial heritage plus serious power handling, which is rare in a passive 10-inch studio monitor. No common failures or maintenance needs are documented, so long-term reliability remains anecdotal. Without sensitivity or frequency response data, the exact performance envelope remains partly speculative.
