Revel PerformaBe Series History
What size room are the Revel M126Be and Revel PerformaBe F328Be 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:

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 Revel M126Be and Revel PerformaBe F328Be compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that M126Be is a 2-way design whereas the F328Be is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

M126Be features a 1" beryllium Hard-Dome Tweeter and 1 x 6.5" DCC Aluminum Woofer . On the other hand, the F328Be features a 1" Tweeter , a 5.25" Midrange and 3 x 8.0" Aluminum Woofer .
Frequency Response
M126Be has a frequency range of 54-44k Hz whereas F328Be has a frequency range of 26-40k Hz. With a minimum frequency of 26Hz, the F328Be can go significantly deeper on the low side and provide stronger bass compared to the M126Be's min frequency of 54Hz.
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.

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
M126Be and F328Be have the same Impedance of 8 ohms but where they differ is the sensitivity levels. M126Be sensitivity is rated at 86 dB and the F328Be's is at 91 dB. This 5 dB difference makes the Revel PerformaBe F328Be a more sensitive speaker compared to Revel M126Be, 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.
M126Be can handle a max power of 300 watts RMS from the amp the whereas M126Be has a max power handling value of 150 watts RMS , 150 watts less than the F328Be.
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
F328Be features 5-way posts posts which make bi-amping or bi-wiring possible. M126Be has a Binding post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both M126Be and F328Be 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 M126Be's and Revel PerformaBe F328Be's external dimensions. Revel M126Be has external dimensions of 388.0 x 212.0 x 262.0mm ( 15-1/4 x 8-5/16 x 10-5/16inch) whereas Revel PerformaBe F328Be has external dimensions of 1294.0 x 343.0 x 448.0mm ( 50-15/16 x 13-1/2 x 17-5/8inch) .
Revel PerformaBe F328Be is clearly the larger of the two speakers. Its body is 131mm wider, 906mm taller and 186mm deeper than Revel M126Be.
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 M126Be is approximately 555.4cm2 / 86.1inch2 and base area of the Revel PerformaBe F328Be is approximately 1536.6cm2 / 238.2inch2. The M126Be requires 64% less surface area than the F328Be which gives it a small advantage on placement in tight spaces.
