New from Britain's Abbingdon Music Research is the LS-77 monitor, designed to provide full-range performance without the need for a subwoofer or super-tweeter from a compact speaker measuring 10" W x 19" H x 12" D. The LS-77's enclosure is made from 3/8" to 1" solid aluminum available in either Champagne or Titanium finishes. The 10" bass driver features a 4" voice coil and a proprietary transmission line port system which allows for response down to 26Hz.

AMR claims that the unusually steep 60 dB/octave crossover known as "OptiSlope" allows the woofer to seamlessly integrate with the 5" isoplanar tweeter. AMR also designed the LS-77 to be stackable, with multiple units forming an "OptiArray" line source for use in rooms up to 480 square meters. The LS-77 is rated at 26Hz - 40kHz (+/-3dB), with 87dB/W/m sensitivity and 8 Ohm impedance.

Call me a traditionalist but I don't believe a sound system is complete with out a dedicated subwoofer shaking the walls and rattling the windows.
