Blade Two Meta features a 1" aluminium dome with MAT Tweeter, a 5" Midrange and 4 x 6.5" aluminium cone Woofer with a Crossover frequency at 450Hz and 2200Hz. On the other hand, the PerformaBe F228Be features a 1" beryllium dome with proprietary acoustic lens waveguide Tweeter, a 5.25" Midrange and 2 x 8" DCC Aluminum Woofer.
Frequency Response
Blade Two Meta has a frequency range of 33-35k Hz whereas PerformaBe F228Be has a frequency range of 27-44k Hz. With a minimum frequency of 27Hz, the PerformaBe F228Be can go significantly deeper on the low side and provide stronger bass compared to the Blade Two Meta's min frequency of 33Hz.
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
Blade Two Meta is a 4 ohms speaker compared to the PerformaBe F228Be 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 Blade Two Meta can provide this impedance level.
These two speakers also have different sensitivity levels. Blade Two Meta sensitivity is rated at 86 dB and the PerformaBe F228Be's is rated at 90 dB. This 4 dB difference makes the Revel PerformaBe F228Be a more sensitive speaker compared to KEF Blade Two Meta, 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.
Blade Two Meta can handle a max power of 400 watts RMS, whereas PerformaBe F228Be has a max power handling value of 350 watts RMS, 50 watts less than the Blade Two Meta.
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 Blade Two Meta and PerformaBe F228Be 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 KEF Blade Two Meta's and Revel PerformaBe F228Be's external dimensions. KEF Blade Two Meta has external dimensions of 1461 x 338 x 475 mm (57.5 x 13.3 x 18.7 in.) whereas Revel PerformaBe F228Be has external dimensions of 1182.0 x 301.0 x 337.0mm (46-1/2 x 11-13/16 x 13-1/4inch).
KEF Blade Two Meta is clearly the larger of the two speakers. Its body is 37mm wider, 279mm taller and 138mm deeper than Revel PerformaBe F228Be.
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.
KEF Blade Two Meta needs about 58% more floor or shelf area. KEF Blade Two Meta is 138mm deeper, so it stands that much further out from the wall. KEF Blade Two Meta is 279mm 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 KEF Blade Two Meta is approximately 1605.5cm2 / 248.9inch2 and base area of the Revel PerformaBe F228Be is approximately 1014.4cm2 / 157.2inch2. The Blade Two Meta requires 58% more surface area than the PerformaBe F228Be 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 KEF Blade Two Meta weighs 35.50kg / 78.1lbs and the Revel PerformaBe F228Be weighs 37.27kg / 82lbs. This makes the PerformaBe F228Be 5% heavier than the Blade Two Meta.
Here is a comparison of how Blade Two Meta and PerformaBe F228Be's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - KEF Blade Two Meta costs roughly 2.5x what Revel PerformaBe F228Be 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 F228Be digs deeper - 27Hz against 33Hz. A subwoofer would even that out. |
| Amplifier needs | B | Revel PerformaBe F228Be is more sensitive (90dB vs 86dB), so it goes louder on the same amplifier. |
| Amplifier match | B | Revel PerformaBe F228Be is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | evenly matched | Similar power handling (400W vs 350W). |
| Size | depends | Revel PerformaBe F228Be is easier to place; KEF Blade Two Meta is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | KEF Blade Two Meta: bi-amping; Revel PerformaBe F228Be: bi-amping. |
| Price | B | Revel PerformaBe F228Be is cheaper - $11,000 against $28,000, about 61% less; arguably a different class. |
A KEF Blade Two Meta B Revel PerformaBe F228Be
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 F228Be is the easier recommendation: it leads on most of the measured areas and costs less. Take KEF Blade Two Meta if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 33Hz anyway, so judge these on the other rows instead. In a large or open-plan room, KEF Blade Two Meta has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Revel PerformaBe F228Be is the easier speaker to get right.
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.
