What size room are the MartinLogan Axis and B&W CWM664 speakers good for?

The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:

Listening Environment* MartinLogan Axis B&W CWM664
Near-field Poor Poor
Small Room Poor Average
Mid-size Room Good Good
Large Room Good Average
Very Large Room Average Poor

(* Approximate Room sizes: Small < 100sq. ft / 9 m2, Mid-size: 100-220 sq. ft / 9-20 m2, Large 220-400 sq. ft / 20-36 m2, Very Large: > 400 sq. ft / 36 m2. Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual listening experience changes depending on floor height, room shape, surface materials, listening position, speaker locations, etc.)

In the following sections, we will get into more detail in order to better understand how the MartinLogan Axis and B&W CWM664 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.

Impedance and Sensitivity

Axis is a 4 ohms speaker compared to the CWM664 which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Axis can provide this impedance level.

These two speakers also have different sensitivity levels. Axis sensitivity is rated at 94 dB and the CWM664's is rated at 87.5 dB. This 6 dB difference makes the MartinLogan Axis a more sensitive speaker compared to B&W CWM664, hence will play louder with the same amount of watts.

Power Range

Power range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.

Axis can handle a max power of 250 watts RMS from the amp the whereas CWM664 has a max power handling value of 130 watts RMS, 120 watts less than the Axis.

Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters such as Impedance, sensitivity and system efficiencies.

Input Type and Bi-Amping / Bi-Wiring

Axis features Spring post type posts and CWM664 has a Spring post type posts. None of these speakers feature bi-amping/bi-wiring.
