Concerta2 C25 features a 1" aluminum dome with proprietary acoustic lens and waveguide Tweeter and 2 x 5.25" anodized aluminum cone 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
Concerta2 C25 has a frequency range of 80Hz- 20kHz whereas M8 SP2 has a frequency range of 110-21k Hz. With a minimum frequency of 80Hz, the Concerta2 C25 can go significantly deeper on the low side and provide stronger bass compared to the M8 SP2's min frequency of 110Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Concerta2 C25 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. Concerta2 C25 sensitivity is rated at 89 dB and the M8 SP2's is rated at 88 dB. This 1 dB difference makes the Revel Concerta2 C25 a more sensitive speaker compared to Revel M8 SP2, 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
M8 SP2 can handle a max power of 125 watts RMS, whereas Concerta2 C25 has a max power handling value of 120 watts RMS, 5 watts less than the M8 SP2.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.

Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring

Revel Concerta2 C25 has external dimensions of 188.0 x 496.0 x 259.0mm (7-3/8 x 19-1/2 x 10-3/16inch) 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 M8 SP2 is 388mm narrower and 141mm less deeper than Revel Concerta2 C25 but it is also 109mm taller.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Revel Concerta2 C25 needs about 908% more floor or shelf area. Revel Concerta2 C25 is 141mm deeper, so it stands that much further out from the wall. Revel M8 SP2 is 109mm taller.
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 Concerta2 C25 is approximately 1284.6cm2 / 199.1inch2 and base area of the Revel M8 SP2 is approximately 127.4cm2 / 19.7inch2. The Concerta2 C25 requires 908% more surface area than the M8 SP2 which gives it a small disadvantage on placement in tight spaces.
