What size room are the MartinLogan Foundation F2 and Klipsch RP-8000F II 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.)
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 Foundation F2 is a 3-way design whereas the RP-8000F II is a 2-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.

Foundation F2 features a 1" Gen2 Obsidian Folded Motion Ribbon Tweeter, a 5.5" Midrange and 3 x 6.5" Aluminum Woofer with a Crossover frequency at 330 Hz - 3600 Hz. On the other hand, the RP-8000F II features a 1" titanium Tractrix Horn Tweeter and 2 x 8" Cerametallic cone Woofer with a Crossover frequency at 1630 Hz.
Frequency Response
Foundation F2 has a frequency range of 36-23k Hz whereas RP-8000F II has a frequency range of 32-25k Hz. With a minimum frequency of 32Hz, the RP-8000F II can go slightly deeper then the Foundation F2's min frequency of 36Hz.
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
Foundation F2 is a 4 ohms speaker compared to the RP-8000F II 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 Foundation F2 can provide this impedance level.
These two speakers also have different sensitivity levels. Foundation F2 sensitivity is rated at 92 dB and the RP-8000F II's is rated at 98 dB. This 6 dB difference makes the Klipsch RP-8000F II a more sensitive speaker compared to MartinLogan Foundation F2, 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.
Foundation F2 can handle a max power of 200 watts RMS, whereas RP-8000F II has a max power handling value of 150 watts RMS, 50 watts less than the Foundation F2.
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
RP-8000F II features Binding post posts which make bi-amping or bi-wiring possible. Foundation F2 has a Binding post which doesn't feature bi-amping/bi-wiring.
MartinLogan Foundation F2's Binding post terminals
Klipsch RP-8000F II's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Foundation F2 and RP-8000F II 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
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 MartinLogan Foundation F2's and Klipsch RP-8000F II's external dimensions. MartinLogan Foundation F2 has external dimensions of 1129.0 x 223.0 x 407.0mm (44-7/16inch x 8-3/4inch x 16inch) whereas Klipsch RP-8000F II has external dimensions of 1097.0 x 277.0 x 447.0mm (43-3/16 x 10-7/8 x 17-9/16inch).
MartinLogan Foundation F2 is 54mm narrower and 40mm less deeper than Klipsch RP-8000F II but it is also 32mm taller.
Below you can see the front view size comparison of MartinLogan Foundation F2 and Klipsch RP-8000F II in scale.

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 MartinLogan Foundation F2 is approximately 907.6cm2 / 140.7inch2 and base area of the Klipsch RP-8000F II is approximately 1238.2cm2 / 191.9inch2. The Foundation F2 requires 27% less surface area than the RP-8000F II which gives it a small advantage 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 MartinLogan Foundation F2 weighs 23.86kg / 52.5lbs and the Klipsch RP-8000F II weighs 28.00kg / 61.6lbs. This makes the RP-8000F II 17% heavier than the Foundation F2.
Here is a comparison of how Foundation F2 and RP-8000F II's weights compare with the average, max and min weights in Passive Floor-standing class.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass | B | Klipsch RP-8000F II digs deeper - 32Hz against 36Hz. A subwoofer would even that out. |
| Amplifier needs | B | Klipsch RP-8000F II is more sensitive (98dB vs 92dB), so it goes louder on the same amplifier. |
| Amplifier match | B | Klipsch RP-8000F II is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | A | MartinLogan Foundation F2 takes more power (200W vs 150W) - more in hand in a big room. |
| Size | depends | MartinLogan Foundation F2 is easier to place; Klipsch RP-8000F II is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | B | Klipsch RP-8000F II: bi-amping and Atmos drivers. Klipsch RP-8000F II sits in a wider range (10 models), so a matched surround system is easier later. |
| Price | B | Klipsch RP-8000F II is cheaper - $1,798 against $1,999, about 10% less. |
A MartinLogan Foundation F2 B Klipsch RP-8000F II
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?
Klipsch RP-8000F II is the easier recommendation: it leads on most of the measured areas and costs less. Take MartinLogan Foundation F2 if its size, looks or fit in your room suit you better. If your amplifier is modest, vintage or valve-based, Klipsch RP-8000F II is the safer partner - the other will want more current or more watts to sound its best.
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.
