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.

Cabinet Type and Port Position

Both The Nines and M20 HD have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.

If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.

Physical Specs

Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Klipsch The Nines's and Q Acoustics M20 HD's external dimensions. Klipsch The Nines has external dimensions of 493.0 x 243.0 x 399.0mm ( 19.375inch x 9.5625inch x 15.6875inch ) whereas Q Acoustics M20 HD has external dimensions of 278.0 x 170.0 x 310.0mm ( 10-15/16 x 6-11/16 x 12-3/16inch) .

Klipsch The Nines is clearly the larger of the two speakers. Its body is 73mm wider, 215mm taller and 89mm deeper than Q Acoustics M20 HD.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited. The base surface area of the Klipsch The Nines is approximately 969.6cm2 / 150.3inch2 and base area of the Q Acoustics M20 HD is approximately 527.0cm2 / 81.7inch2. The The Nines requires 84% more surface area than the M20 HD which gives it a small disadvantage on placement in tight spaces.

Weight Comparison

The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Klipsch The Nines weighs 12.25kg / 27lbs and the Q Acoustics M20 HD weighs 5.10kg / 11.2lbs. This makes the The Nines 140% heavier than the M20 HD.
