But can they compete with the dedicated monitors already on the market...? B&W are one of the few British hi?fi loudspeaker manufacturers who have managed to maintain a prominent market position while sticking to basic engineering principles, rather than following the quasi?mystic fashions of the hi?fi tweater. The CDM1s under review might look a little unusual, but even the cabinet shape is based on established principles, and the speaker system itself is a fairly conventional, two?way, passive arrangement in a ported cabinet. Although designed as hi?fi speakers, the CDM1s are quite capable of producing monitoring level SPLs when used in the near field, and the tonal integrity holds together well up to surprisingly high levels.At the heart of the system is a 165mm bass/mid driver comprising a woven Kevlar cone suspended in a substantial die?cast basket, and driven by a 31mm voice coil. Handling the top end is a free?mounted, 26mm, alloy dome tweeter, incorporating a high?power voice coil working in a magnetic fluid?filled gap for cooling. Feeding the two drivers is a passive crossover, which, when combined with the natural characteristics of the drivers, produces a 4th order filter characteristic with a crossover point at 3kHz. The resulting system has a usefully wide frequency range, covering 64Hz to 20kHz +/? 2dB, and is only 6dB down at 46Hz and 25kHz. This isnt as extended as youd expect from a larger mid?sized, or main monitoring system, but is more than adequate for nearfield work, and is much less likely to excite modal resonance problems in small rooms which have little, or no, acoustic treatment.Considering their small size, the CDM1s are surprisingly efficient at 88dB for 2.83V input at 1m, which, in non?technical terms, means that an amplifier capable of delivering between 50W and 120W will give you sufficient wellie for monitoring without clipping. For hi?fi use, you can go as low as 30W per channel, but in the studio, Id be inclined to think along the lines of 75W a side, or more, unless you are in the habit of always monitoring at restrained levels. Although nominally rated as 8? speakers, the impedance drops to almost half that value near resonance, so be sure to use an amplifier capable of driving 4? loads or below.The cabinet itself deserves comment, as apart from being very stylish, the radiused edges are there to reduce cabinet edge diffraction, and while the sloping tweeter baffle may look like a cosmetic add?on, it was probably introduced to deflect baffle reflections away from the listener. The tweeter itself is free?mounted (not fixed directly to the baffle), so that it still points directly forward, and a mesh dome is fixed over it for protection.Connection to the speakers is via chunky terminals on the back panel, and two sets of terminals are fitted for those who prefer bi?wiring. The holes in the terminal (which accept either bare wires or banana plugs) are generously large, and should accommodate all but the most esoterically butch speaker cables.
