In this review, we will be comparing MartinLogan Foundation F2 and RP-8000F II, two Passive Floor-standing speakers from MartinLogan and Klipsch. Let's have a brief look at the main features
of MartinLogan Foundation F2 and Klipsch RP-8000F II first before getting into our more
detailed comparison.
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:
In the following sections, we will get into more detail in order to better understand how the MartinLogan Foundation F2 and Klipsch RP-8000F II compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that MartinLogan 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.

MartinLogan 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
MartinLogan 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 MartinLogan Foundation F2's min frequency of 36Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Floor-standing class in our database.

MartinLogan Foundation F2
None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
MartinLogan 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 MartinLogan Foundation F2 can provide this impedance level.
These two speakers also have different sensitivity levels. MartinLogan 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.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
MartinLogan Foundation F2 can handle a max power of 200 watts RMS from the amp the whereas RP-8000F II has a max power handling value of 150 watts RMS, 50 watts less than the MartinLogan Foundation F2.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
RP-8000F II features Binding post posts which make bi-amping or bi-wiring possible. MartinLogan Foundation F2 has a Binding post which doesn't feature bi-amping/bi-wiring.

Klipsch RP-8000F II's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both MartinLogan 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
Size of a speaker can sometimes become 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.
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 MartinLogan 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 MartinLogan Foundation F2.
Here is a comparison of how MartinLogan Foundation F2 and RP-8000F II's weights compare with the average, max and min weights in Passive Floor-standing class.
