Drivers
One of the fundamental differences between these two speakers is that .7 is a -way design whereas the Prime Tower 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.

.7 features a " Tweeter and x " Woofer. On the other hand, the Prime Tower features a 1" aluminum dome Tweeter, a 4.5" Midrange and 2 x 6.5" Polypropylene Woofer with a Crossover frequency at 350Hz and 2100Hz.
Frequency Response
.7 has a frequency range of 45-22k Hz whereas Prime Tower has a frequency range of 30-25k Hz. With a minimum frequency of 30Hz, the Prime Tower can go significantly deeper on the low side and provide stronger bass compared to the .7's min frequency of 45Hz.
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
.7 is a 4 ohms speaker compared to the Prime Tower 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 .7 can provide this impedance level.
These two speakers also have different sensitivity levels. .7 sensitivity is rated at 86 dB and the Prime Tower's is rated at 87 dB. This 1 dB difference makes the SVS Prime Tower a more sensitive speaker compared to Magnepan .7, hence will play louder with the same amount of watts.

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 Magnepan .7's and SVS Prime Tower's external dimensions. Magnepan .7 has external dimensions of 1378.0 x 387.4 x 31.8mm (54.25 x 15.25 x 1.25inch) whereas SVS Prime Tower has external dimensions of 931.0 x 204.0 x 297.0mm (36-5/8 x 8 x 11-11/16inch).
SVS Prime Tower is 183.4mm narrower and 447mm shorter than Magnepan .7 but it is also 265.2mm deeper.
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 Magnepan .7 is approximately 123.2cm2 / 19.1inch2 and base area of the SVS Prime Tower is approximately 605.9cm2 / 93.9inch2. The .7 requires 80% less surface area than the Prime Tower which gives it a small advantage on placement in tight spaces.
