What size room are the Klipsch RP-4000F and Jamo S 807 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:

RP-4000F features a 1" Tractrix Horn Tweeter and 2 x 4" Cerametallic Woofer with a Crossover frequency at 1500 Hz. On the other hand, the S 807 features a 1" Tweeter and 2 x 5" Aluminized Polyfiber Woofer with a Crossover frequency at 2000Hz.
Frequency Response
RP-4000F has a frequency range of 37-25k Hz whereas S 807 has a frequency range of 42-26k Hz. With a minimum frequency of 37Hz, the RP-4000F can go significantly deeper on the low side and provide stronger bass compared to the S 807's min frequency of 42Hz.
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
RP-4000F and S 807 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-4000F sensitivity is rated at 95 dB and the S 807's is at 90 dB. This 5 dB difference makes the Klipsch RP-4000F a more sensitive speaker compared to Jamo S 807, 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.
S 807 can handle a max power of 100 watts RMS, whereas RP-4000F has a max power handling value of 75 watts RMS, 25 watts less than the S 807.
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
RP-4000F features Binding post posts which make bi-amping or bi-wiring possible. S 807 has a Binding post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
RP-4000F has a rear firing port whereas S 807 has a front firing ports. Jamo S 807's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Klipsch RP-4000F with its rear-firing port.

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 Klipsch RP-4000F's and Jamo S 807's external dimensions. Klipsch RP-4000F has external dimensions of 870.0 x 188.0 x 289.0mm (34-1/4 x 7-3/8 x 11-3/8inch) whereas Jamo S 807 has external dimensions of 915 x 191 x 252 mm (36 x 7-1/2 x 9-15/16 inch).
Klipsch RP-4000F is 3mm narrower and 45mm shorter than Jamo S 807 but it is also 37mm deeper.
Below you can see the front view size comparison of Klipsch RP-4000F and Jamo S 807 in scale.

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 Klipsch RP-4000F is approximately 543.3cm2 / 84.2inch2 and base area of the Jamo S 807 is approximately 481.3cm2 / 74.6inch2. The RP-4000F requires 13% more surface area than the S 807 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 Klipsch RP-4000F weighs 13.18kg / 29lbs and the Jamo S 807 weighs 11.80kg / 26lbs. This makes the RP-4000F 12% heavier than the S 807.
Here is a comparison of how RP-4000F and S 807's weights compare with the average, max and min weights in Passive Floor-standing class.

A generation apart: Klipsch RP-4000F is the newer design, against a 2017 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | A | Klipsch RP-4000F digs deeper - 37Hz against 42Hz. A subwoofer would even that out. |
| Amplifier needs | A | Klipsch RP-4000F is more sensitive (95dB vs 90dB), so it goes louder on the same amplifier. |
| Headroom | B | Jamo S 807 takes more power (100W vs 75W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Klipsch RP-4000F: bi-amping; Jamo S 807: Atmos drivers. Klipsch RP-4000F sits in a wider range (17 models), so a matched surround system is easier later. |
| Price | B | Jamo S 807 is cheaper - $519 against $698, about 26% less. |
A Klipsch RP-4000F B Jamo S 807
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?
Klipsch RP-4000F is ahead, but only on 1 of the measured areas, and it costs about 34% more. That is a lot of money for a narrow margin on paper - Jamo S 807 looks like the sensible buy unless something else about the Klipsch RP-4000F appeals to you. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 42Hz anyway, which makes the cheaper Jamo S 807 much easier to justify. Match it to your room: we rate Klipsch RP-4000F the better fit for a large room; elsewhere the two are rated the same.
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.
