What size room are the SVS Prime Tower and Klipsch R-625FA 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 Prime Tower is a 3-way design whereas the R-625FA 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.

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. On the other hand, the R-625FA features a 1" Tweeter and 2 x 6.5" Copper-spun IMG Woofer with a Crossover frequency at 2000Hz.
Frequency Response
Prime Tower has a frequency range of 30-25k Hz whereas R-625FA has a frequency range of 38-21k 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 R-625FA's min frequency of 38Hz.
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
Prime Tower and R-625FA have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Prime Tower sensitivity is rated at 87 dB and the R-625FA's is at 96 dB. This 9 dB difference makes the Klipsch R-625FA a more sensitive speaker compared to SVS Prime Tower, 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.
Prime Tower can handle a max power of 250 watts RMS, whereas R-625FA has a max power handling value of 100 watts RMS, 150 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
Prime Tower features Post type posts and R-625FA has a Post type posts. None of these speakers feature bi-amping/bi-wiring.
SVS Prime Tower's 5-Way post terminals
Klipsch R-625FA's Post terminals
Cabinet Type and Port Position
Both Prime Tower and R-625FA 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 SVS Prime Tower's and Klipsch R-625FA's external dimensions. SVS Prime Tower has external dimensions of 931.0 x 204.0 x 297.0mm (36-5/8 x 8 x 11-11/16inch) whereas Klipsch R-625FA has external dimensions of 1021.0 x 239.0 x 426.0mm (40-3/16 x 9-3/8 x 16-3/4inch).
Klipsch R-625FA is clearly the larger of the two speakers. Its body is 35mm wider, 90mm taller and 129mm 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 SVS Prime Tower is approximately 605.9cm2 / 93.9inch2 and base area of the Klipsch R-625FA is approximately 1018.1cm2 / 157.8inch2. The Prime Tower requires 40% less surface area than the R-625FA 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 SVS Prime Tower weighs 18.23kg / 40.1lbs and the Klipsch R-625FA weighs 22.20kg / 48.8lbs. This makes the R-625FA 22% heavier than the Prime Tower.

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 | A | SVS Prime Tower digs deeper - 30Hz against 38Hz. A subwoofer would even that out. |
| Amplifier needs | B | Klipsch R-625FA is more sensitive (96dB vs 87dB), so it goes louder on the same amplifier. |
| Headroom | A | SVS Prime Tower takes more power (250W vs 100W) - more in hand in a big room. |
| Size | depends | SVS Prime Tower is easier to place; Klipsch R-625FA is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Klipsch R-625FA: Atmos drivers. SVS Prime Tower sits in a wider range (8 models), so a matched surround system is easier later. |
| Price | A | SVS Prime Tower is cheaper - $1,400 against $1,658, about 16% less. |
A SVS Prime Tower B Klipsch R-625FA
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 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 38Hz anyway, so judge these on the other rows instead. Match it to your room: we rate SVS Prime Tower the better fit for a large room and a very large room, and Klipsch R-625FA for a small room and a mid-size room.
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.
