B&W CDM1 Speakers

Description

The Bowers & Wilkins CDM1 is a classic 2‑way bookshelf/stand‑mount loudspeaker from one of the most respected names in high‑end audio. Designed for discerning listeners who want compact, refined performance without sacrificing musical authority, these speakers were originally introduced in the mid‑1990s and quickly earned attention for their balanced tonal character, expressive midrange, and surprisingly deep bass for their size.

While modest in physical dimensions, the CDM1 “punches above its weight” thanks to a thoughtfully engineered driver complement and sturdy cabinet. It uses Bowers & Wilkins’ Tweeter‑on‑Top design, where the tweeter sits above the main cabinet to reduce diffraction and improve time‑alignment, leading to more cohesive stereo imaging and a more realistic soundstage.

In the bass/midrange region, the CDM1 sports a 165 mm (6.5″) Kevlar®‑cone driver, a material famously developed by B&W for its stiffness and ability to minimize unwanted resonances (originally created by DuPont for tough applications like body armor). This Kevlar driver delivers tight, well‑controlled midrange and bass, contributing to the speaker’s clear, natural tonal balance.

The tweeter is a 25 mm (1″) lightweight alloy dome, chosen for its ability to extend high‑frequency detail and deliver smooth, sparkling treble without harshness. This combination of drivers covers most of the audible spectrum with ease and musicality.

Physically, the CDM1 is neither imposing nor fragile. Its wood‑veneered cabinet with braced construction helps reduce cabinet resonance that can muddy sound, while gold‑plated terminals allow for bi‑wiring or bi‑amping for audiophile setups. The speaker’s elegant wood finishes — often including Black Ash, Cherrywood, or Red Ash — and black cloth grilles give it a timeless aesthetic that fits both classic and modern systems.

Sonically, the CDM1 has often been described as cohesive, highly musical, and articulate — qualities that make it strong with vocals, jazz, classical, and acoustic rock alike. While small bookshelf speakers inherently have limitations with very deep bass, many listeners report that the CDM1 still delivers surprising low‑end extension for its class, especially when paired with a decent amplifier.

Because these speakers are from an earlier era — and B&W has since expanded and refined its range — they are more commonly found on the used market today. Vintage‑gear enthusiasts frequently highlight their audiophile‑leaning neutrality and smooth midrange, making them excellent candidates for two‑channel music systems in smaller rooms or as front speakers in modest home‑theater setups.

Over the years, the CDM1 line spawned special editions like the CDM1 SE and later iterations such as the CDM 1NT, which introduced refinements like Flowport™ reflex ports and improved cabinets. However, the fundamental traits — balanced sound, detailed high‑end, and robust midrange — remain hallmarks of the original model.
