The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that Epikore 9 is a 4-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.

Epikore 9 features a 1.38" Hybrid dome + planar Tweeter, a 6.5" Midrange and 2 x 8" Wood fibre Woofer with a Crossover frequency at 400 / 3100 / 12500Hz. On the other hand, the F328Be features a 1" Tweeter, a 5.25" Midrange and 3 x 8.0" Aluminum Woofer.
Frequency Response
Epikore 9 has a frequency range of 29-34k Hz whereas F328Be has a frequency range of 26-40k Hz. With a minimum frequency of 26Hz, the F328Be can go slightly deeper then the Epikore 9's min frequency of 29Hz.
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
Epikore 9 is a 4 ohms speaker compared to the F328Be which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Epikore 9 can provide this impedance level.
These two speakers also have different sensitivity levels. Epikore 9 sensitivity is rated at 88 dB and the F328Be's is rated at 91 dB. This 3 dB difference makes the Revel PerformaBe F328Be a more sensitive speaker compared to DALI Epikore 9, 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.
Epikore 9 can handle a max power of 500 watts RMS, whereas F328Be has a max power handling value of 300 watts RMS, 200 watts less than the Epikore 9.
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
Both Epikore 9 and F328Be features dual binding post speaker terminals for bi-amping or 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 DALI Epikore 9's and Revel PerformaBe F328Be's external dimensions. DALI Epikore 9 has external dimensions of 1311 x 422 x 554 mm () 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).
DALI Epikore 9 is clearly the larger of the two speakers. Its body is 79mm wider, 17mm taller and 106mm deeper than Revel PerformaBe F328Be.
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.
DALI Epikore 9 needs about 52% more floor or shelf area. DALI Epikore 9 is 106mm deeper, so it stands that much further out from the wall. DALI Epikore 9 is 17mm 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 DALI Epikore 9 is approximately 2337.9cm2 / 362.4inch2 and base area of the Revel PerformaBe F328Be is approximately 1536.6cm2 / 238.2inch2. The Epikore 9 requires 52% more surface area than the F328Be which gives it a small disadvantage on placement in tight spaces.
