factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

Q7 Meta features a 0.75" vented aluminum dome with MAT absorber Hard dome Tweeter, a 4" Midrange and 2 x 6.5" Aluminum Woofer with a Crossover frequency at 440 Hz, 2.3 kHz. 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
Q7 Meta has a frequency range of 46-20k 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 Q7 Meta's min frequency of 46Hz.
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
Q7 Meta 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 Q7 Meta can provide this impedance level.
On the other hand, they have the same sensitivity of 87 dBdB.
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.
Prime Tower can handle a max power of 250 watts RMS, whereas Q7 Meta has a max power handling value of 200 watts RMS, 50 watts less than the Prime Tower.
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
Q7 Meta features 5-Way post type posts and Prime Tower has a 5-Way post type posts. None of these speakers feature bi-amping/bi-wiring.
SVS Prime Tower's 5-Way post terminals
Cabinet Type and Port Position
Both Q7 Meta and Prime Tower 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 KEF Q7 Meta's and SVS Prime Tower's external dimensions. KEF Q7 Meta has external dimensions of 1001 x 317 x 315 mm (39.4 x 12.5 x 12.4 in.) 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).
KEF Q7 Meta is clearly the larger of the two speakers. Its body is 113mm wider, 70mm taller and 18mm deeper than SVS Prime Tower.
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 Q7 Meta is approximately 998.6cm2 / 154.8inch2 and base area of the SVS Prime Tower is approximately 605.9cm2 / 93.9inch2. The Q7 Meta requires 65% more surface area than the Prime Tower 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 Q7 Meta weighs 18.45kg / 40.6lbs and the SVS Prime Tower weighs 18.23kg / 40.1lbs. This makes the Q7 Meta 1% heavier than the Prime Tower.
Here is a comparison of how Q7 Meta and Prime Tower's weights compare with the average, max and min weights in Passive Floor-standing class.

A generation apart: KEF Q7 Meta is the newer design, against a 2015 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | B | SVS Prime Tower digs deeper - 30Hz against 46Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (87dB vs 87dB) - both want much the same power. |
| Amplifier match | B | SVS Prime Tower is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | B | SVS Prime Tower takes more power (250W vs 200W) - more in hand in a big room. |
| Size | depends | SVS Prime Tower is easier to place; KEF Q7 Meta is bigger, which usually goes with fuller bass. Your room decides. |
| Price | B | SVS Prime Tower is cheaper - $1,400 against $1,800, about 22% less. |
A KEF Q7 Meta B SVS Prime Tower
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?
SVS Prime Tower is the easier recommendation: it leads on most of the measured areas and costs less. Take KEF Q7 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 46Hz anyway, so judge these on the other rows instead. In a large or open-plan room, KEF Q7 Meta has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, SVS Prime Tower 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.
