PMC MB2 SE
PMC three-way floorstanding speaker with extended bass, designed for demanding listening in the studio as well as at home.
Description
The MB2 SE is a three-way floorstanding speaker from PMC's SE range, designed for faithful sound reproduction across the entire audible spectrum. It is aimed at setups where bass precision and extension matter as much as clarity in the upper register, whether for stereo listening or professional installations.
The frequency response extends from 26 Hz to 30 kHz, reflecting an ability to reproduce the lowest frequencies without sacrificing detail. The system is built around two 140 mm long-throw woofers, a 50 mm soft dome bass driver cooled by ferro-fluid, and a 19 mm SONOMEX soft dome tweeter, also ferro-fluid cooled, for refined resolution right up into the treble. An impedance of 8 ohms and a sensitivity of 84 dB (1W/1m) place this speaker in a category requiring suitable amplification to make the most of its dynamic potential. The crossover frequencies, at 400 Hz and 4 kHz, define how the workload is divided between the three drive units.
With dimensions of 155 x 1030 x 380 mm and a weight of 20 kg, the MB2 SE is suited to installations with dedicated space for a sizeable floorstanding cabinet, whether in a high-end home cinema or a critical listening room. Its technical profile makes it a relevant choice for listeners seeking particularly extended low-frequency reproduction.

What to check before buying used
On a speaker of this size and age, the condition of the woofer surrounds and bass dome suspension deserves particular attention: the fabric or foam can stiffen or crack over time, which affects low-frequency performance. Each drive unit should also be listened to separately to detect any possible coil fault, particularly on the soft dome tweeter. A visual check of the cabinet finish, often wood veneer, also helps identify any lifting or warping caused by the weight of the unit.
