Floorstanding loudspeakers — PMC MB2S XBD

The MB2S XBD is a large active floorstanding loudspeaker from PMC, built with substantial internal amplification and an exceptionally demanding external power requirement noted alongside that active design. This model sits within PMC's active XBD family, sharing amplification scale with some of the brand's larger active towers while occupying a somewhat more compact footprint within that specific hierarchy.

Key specs that matter

Rated response is 20 Hz to 25 000 Hz. Sensitivity is 91 dB into 4 ohms, with a recommended external power window of 250-900 W listed alongside the substantial internal amplification of 120 plus 600 W across its active bands - this combination suggests the published external figure may relate to a specific passive section or represent a legacy specification worth confirming directly with PMC. At 174.0 x 38.0 x 53.5 cm and 88 kg it is an exceptionally large, heavy tower.

Sound and use context

Expect a highly controlled, full-range presentation with substantial internal amplification matched specifically to PMC's transmission-line driver array - a serious active performer built for a large room and demanding listening or professional monitoring application.

Pairing

As an active design, the internal amplification handles the primary signal path directly from a preamplifier or line-level source; buyers should clarify with PMC or a specialist dealer exactly what role, if any, external amplification plays given the substantial built-in power already provided.

Alternatives

PMC's broader active range, including the MB3-A and larger BB6 XBD-A, offers alternatives at different scales, worth comparing directly with a specialist dealer given the considerable investment and installation planning this active flagship-adjacent tower represents. Given the exceptional scale and weight involved here, professional delivery and structural floor assessment are both essential considerations before this tower arrives, and a dealer conversation clarifying the exact amplification configuration is worth having given the somewhat unusual combination of internal and external power figures published for this model. PMC relatively specialist dealer network worldwide means sourcing an expert familiar with this specific active platform is well worth the research effort. Overall this remains a serious active choice within PMC ambitious XBD product family.
