Performa4 F345 features a 1" Hard-Dome Tweeter and 3 x 5.25" Micro Ceramic Composite (MCC) Woofer. On the other hand, the Performa4 M145 features a 1" Hard-Dome Tweeter and 1 x 5.25" Micro Ceramic Composite (MCC) Woofer.
Frequency Response
Performa4 F345 has a frequency range of 36-40k Hz whereas Performa4 M145 has a frequency range of 54-40k Hz. With a minimum frequency of 36Hz, the Performa4 F345 can go significantly deeper on the low side and provide stronger bass compared to the Performa4 M145's min frequency of 54Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing 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
Performa4 F345 and Performa4 M145 have the same Impedance of 6 ohms but where they differ is the sensitivity levels. Performa4 F345 sensitivity is rated at 87 dB and the Performa4 M145's is at 85 dB. This 2 dB difference makes the Revel Performa4 F345 a more sensitive speaker compared to Revel Performa4 M145, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing Speakers
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.
Performa4 F345 can handle a max power of 225 watts RMS, whereas Performa4 M145 has a max power handling value of 150 watts RMS, 75 watts less than the Performa4 F345.
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.
Which plays louder on your 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
Performa4 F345 features Binding post posts which make bi-amping or bi-wiring possible. Performa4 M145 has a Binding post which doesn't feature bi-amping/bi-wiring.
Physical Specs
The size of a speaker can sometimes be 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 Performa4 F345's and Revel Performa4 M145's external dimensions. Revel Performa4 F345 has external dimensions of 1042.0 x 304.0 x 355.0mm (41inch x 11-15/16inch x 13-15/16inch) whereas Revel Performa4 M145 has external dimensions of 296.0 x 202.0 x 245.0mm (11-5/8inch x 7-15/16inch x 9-5/8inch).
Revel Performa4 F345 is clearly the larger of the two speakers. Its body is 102mm wider, 746mm taller and 110mm deeper than Revel Performa4 M145.
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 Performa4 F345 needs about 118% more floor or shelf area. Revel Performa4 F345 is 110mm deeper, so it stands that much further out from the wall. Revel Performa4 F345 is 746mm 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 Performa4 F345 is approximately 1079.2cm2 / 167.3inch2 and base area of the Revel Performa4 M145 is approximately 494.9cm2 / 76.7inch2. The Performa4 F345 requires 118% more surface area than the Performa4 M145 which gives it a small disadvantage on placement in tight spaces.
