High Frequency
Floor-standing Speakers
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 Borea BR07 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 Borea BR07's is rated at 91 dB. This 1 dB difference makes the MartinLogan Foundation F2 a more sensitive speaker compared to Triangle Borea BR07, 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 Borea BR07 has a max power handling value of 120 watts RMS, 80 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
MartinLogan Foundation F2 features Binding post type posts and Borea BR07 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
MartinLogan Foundation F2 has a rear firing port whereas Borea BR07 has a front firing ports. Triangle Borea BR07's front-firing port gives more flexibility in placement in regards to proximity to walls compared to MartinLogan Foundation F2 with its rear-firing port.
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 Triangle Borea BR07'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 Triangle Borea BR07 has external dimensions of 980.0 x 206.0 x 314.0mm ( 38.5 x 8.1 x 12.3inch) .
MartinLogan Foundation F2 is clearly the larger of the two speakers. Its body is 17mm wider, 149mm taller and 93mm deeper than Triangle Borea BR07.
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 Triangle Borea BR07 is approximately 646.8cm2 / 100.3inch2. The MartinLogan Foundation F2 requires 40% more surface area than the Borea BR07 which gives it a small disadvantage on placement in tight spaces.
