What size room are the ATC SCM150PSL 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:

SCM150PSL features a 0.98" Tweeter, a 2.95" Midrange and 1 x 14.76" Woofer with a Crossover frequency at 380Hz & 3.5kHz. On the other hand, the F328Be features a 1" Tweeter, a 5.25" Midrange and 3 x 8.0" Aluminum Woofer.
Frequency Response
SCM150PSL has a frequency range of 60-17k 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 SCM150PSL's min frequency of 60Hz.
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
SCM150PSL and F328Be have the same Impedance of 8 ohms and their sensitivity is also same at 91 dB.
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.
SCM150PSL can handle a max power of 1500 watts RMS, whereas F328Be has a max power handling value of 300 watts RMS, 1200 watts less than the SCM150PSL.
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
F328Be features 5-way posts posts which make bi-amping or bi-wiring possible. SCM150PSL has a XLR 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 ATC SCM150PSL's and Revel PerformaBe F328Be's external dimensions. ATC SCM150PSL has external dimensions of 884.0 x 498.0 x 568.0mm () 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 155mm narrower and 120mm less deeper than ATC SCM150PSL but it is also 410mm 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.
ATC SCM150PSL needs about 84% more floor or shelf area. ATC SCM150PSL is 120mm deeper, so it stands that much further out from the wall. Revel PerformaBe F328Be is 410mm 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 ATC SCM150PSL is approximately 2828.6cm2 / 438.4inch2 and base area of the Revel PerformaBe F328Be is approximately 1536.6cm2 / 238.2inch2. The SCM150PSL requires 84% more surface area than the F328Be 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 ATC SCM150PSL weighs 67.20kg / 147.8lbs and the Revel PerformaBe F328Be weighs 51.18kg / 112.6lbs. This makes the SCM150PSL 31% heavier than the F328Be.
Here is a comparison of how SCM150PSL and F328Be's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - ATC SCM150PSL costs roughly 2x what Revel PerformaBe F328Be does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | B | Revel PerformaBe F328Be digs deeper - 26Hz against 60Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (91dB vs 91dB) - both want much the same power. |
| Headroom | A | ATC SCM150PSL takes more power (1500W vs 300W) - more in hand in a big room. |
| Size | depends | Revel PerformaBe F328Be is easier to place; ATC SCM150PSL is bigger, which usually goes with fuller bass. Your room decides. |
| Cabinet | depends | Sealed vs Ported. Sealed is tighter and happier near a wall; ported digs lower but wants space behind it. |
| Expandability | B | Revel PerformaBe F328Be: bi-amping. |
| Price | B | Revel PerformaBe F328Be is cheaper - $17,600 against $35,999, about 51% less; arguably a different class. |
A ATC SCM150PSL B Revel PerformaBe F328Be
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Revel PerformaBe F328Be has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 60Hz anyway, so judge these on the other rows instead. Match it to your room: we rate ATC SCM150PSL the better fit for a small room and a mid-size room, and Revel PerformaBe F328Be for a large room and a very large room.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
