Background
Bass is the foundation to music, a key to enjoying full-range music and
spectacular Hollywood soundtracks. Unfortunately, most subwoofers
compensate for a lack of low bass by over-emphasising mid bass. The result is a
boomy character that might impress at first but clouds the midrange and
eventually fatigues the listener.
Meridian, in contrast, emphasizes extreme bass depth, clarity, control,
articulation, slam and attack and the Meridian M1500 Active Subwoofer is
designed to bring you the highest quality sound possible, whether as part of an
enhanced stereo system or a full home theatre.
Meridian M1500
Using a 100-watt amplifier wired directly to a 10-inch woofer in an active
configuration, the M1500 provides far more bass energy than a conventional
design of the same power. The subwoofer is easily capable of visceral bass for
subterranean theatre effects, yet nimble enough to teat the most subtle music
with delicacy.
The M1500 has left and right unbalanced inputs with both positive and negative
phase connections, a switchable electronic crossover and a 100-Watt high-
efficiency bipolar amplifier design. It is fully shielded for use close to monitors
and televisions and, like all Meridian subwoofers, is constructed from 22mm MDF
which is both braced and damped.
The crossover in the M1500 is a second order Butterworth design with switchable
settings at 80Hz and 120Hz. It can also be switched to the “OFF” position,
bypassing the internal crossover to allow better integration between the M1500
and surround sound controllers that feature internal crossovers on their
dedicated subwoofer outputs.
