The DNA of the M1 in a more compact floor standing stereo speaker.
M7b speaker

The M7b speaker is built with the same crossovers, stainless steel parts and quality of construction as the M2 model. The M7b drivers are the same as used in the M1 reference speaker model. The high efficiency is 100dB/1Watt/1 meter (8 Ohms nominal impedance). The M7 comes in brilliant piano black finish and replaces the Edimoe hardwood finish of the previous version. The height of the M7 is pleasing to many listeners, and integrates will with most residential furnishings due to the elegant brilliant piano black finish.

The M7 can be placed in almost any location, due to its controlled dispersion. Listeners will hear full, natural sound anywhere in the room due to the way the M7 projects. Speaker cables can be as long as required because the load presented by the M7 does not require high power from the amplifier. Daniel Hertz Premium 500 speaker cable is highly recommended for the M7.

The ideal electronics for the M7 are one pair of M5 Mono Reference Amplifiers, and an M6 1 MegOhms Preamplifier. The M7 can also be powered by the M9 Amplifier and a wide range of modestly priced amplifiers with excellent results, due to its high efficiency and 8 Ohms impedance.

Owners of low power vacuum tube electronics will find the M7 a delightful choice. For normal listening, the M7 requires only a few Watts of power to generate substantial volume, and is easy for tube amps to drive. With the M5 and M6 electronics, M7 owners will have the most highly refined sonic quality, wide dynamic range, punch, no audible electrical or mechanical noise, and high reliability.
