M16 features a 1" aluminum Dome Tweeter and 1 x 6.5" Anodized aluminum Woofer . On the other hand, the M8 SP2 features a 1" MCC (Micro Ceramic Composite) Hard-Dome Tweeter and 2 x 3" Micro Ceramic Composite Woofer .
Frequency Response
M16 has a frequency range of 55- Hz whereas M8 SP2 has a frequency range of 110-21k Hz. With a minimum frequency of 55Hz, the M16 can go significantly deeper on the low side and provide stronger bass compared to the M8 SP2's min frequency of 110Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Bookshelf class in our database.
Low Frequency

High Frequency
Bookshelf Speakers
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
M16 is a 6 ohms speaker compared to the M8 SP2 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. M16 sensitivity is rated at 86 dB and the M8 SP2's is rated at 88 dB. This 2 dB difference makes the Revel M8 SP2 a more sensitive speaker compared to Revel M16, 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.
M16 can handle a max power of 125 watts RMS from the amp the whereas M16 has a max power handling value of 120 watts RMS , 5 watts less than the M8 SP2.
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
M16 features 5-way post type posts and M8 SP2 has a 5-way post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both M16 and M8 SP2 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 Revel M16's and Revel M8 SP2's external dimensions. Revel M16 has external dimensions of 378.0 x 221.0 x 280.0mm ( 14-7/8 x 8-11/16 x 11inch) whereas Revel M8 SP2 has external dimensions of 297.0 x 108.0 x 118.0mm ( 11-11/16 x 4-1/4 x 4-5/8inch) .
Revel M16 is clearly the larger of the two speakers. Its body is 113mm wider, 81mm taller and 162mm deeper than Revel M8 SP2.
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 Revel M16 is approximately 618.8cm2 / 95.9inch2 and base area of the Revel M8 SP2 is approximately 127.4cm2 / 19.7inch2. The M16 requires 386% more surface area than the M8 SP2 which gives it a small disadvantage on placement in tight spaces.
