Bounding Unicorns

Speaker Specifications

This page collects specifications for the various speakers I have either owned or come across on Craigslist.

Millennium Theater System MTS 2328

The sticker on the back of the speaker claims:

  • 3-way bass reflex system
  • Min power: 20 W
  • Max power: 400 W
  • Titanium tweeter
  • Sealed back midrange
  • Dual 8" P.P. coated woofers
  • Sensitivity: 92 dB @ 1 W/1 m
  • Frequency response: 40 Hz-22 kHz
  • Impedance: 4-8 ohms

The 400 W power is surely peak, not continuous. They would handle perhaps about 100 W of continuous power max?

The "4-8 ohms" impedance is also interesting. Does this make them a 4 ohm speaker nominally?

Dimensions given by a seller: 40" height, 10" width, 11" depth.

They do look a-ok with the grilles on.
