What size room are the Mission LX-4 MKII 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:

The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both LX-4 MKII and S 807 are 2-way speakers.

LX-4 MKII features a 1" Microfibre Soft-Dome Tweeter and 2 x 5" Composite fibre Woofer with a Crossover frequency at 3.0kHz. 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
LX-4 MKII has a frequency range of 45-20k Hz whereas S 807 has a frequency range of 42-26k Hz. With a minimum frequency of 42Hz, the S 807 can go slightly deeper then the LX-4 MKII'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
LX-4 MKII and S 807 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. LX-4 MKII sensitivity is rated at 89 dB and the S 807's is at 90 dB. This 1 dB difference makes the Jamo S 807 a more sensitive speaker compared to Mission LX-4 MKII, 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.
LX-4 MKII can handle a max power of 120 watts RMS, whereas S 807 has a max power handling value of 100 watts RMS, 20 watts less than the LX-4 MKII.
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
LX-4 MKII 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.

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 Mission LX-4 MKII's and Jamo S 807's external dimensions. Mission LX-4 MKII has external dimensions of 920.0 x 200.0 x 273.0mm (36-1/4 x 7-7/8 x 10-3/4inch) whereas Jamo S 807 has external dimensions of 915 x 191 x 252 mm (36 x 7-1/2 x 9-15/16 inch).
Mission LX-4 MKII is clearly the larger of the two speakers. Its body is 9mm wider, 5mm taller and 21mm deeper than Jamo S 807.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Mission LX-4 MKII needs about 13% more floor or shelf area. Mission LX-4 MKII is 21mm deeper, so it stands that much further out from the wall.
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 Mission LX-4 MKII is approximately 546.0cm2 / 84.6inch2 and base area of the Jamo S 807 is approximately 481.3cm2 / 74.6inch2. The LX-4 MKII 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 Mission LX-4 MKII weighs 15.50kg / 34.1lbs and the Jamo S 807 weighs 11.80kg / 26lbs. This makes the LX-4 MKII 31% heavier than the S 807.
Here is a comparison of how LX-4 MKII and S 807's weights compare with the average, max and min weights in Passive Floor-standing class.

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 | B | Jamo S 807 digs deeper - 42Hz against 45Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (89dB vs 90dB) - both want much the same power. |
| Headroom | evenly matched | Similar power handling (120W vs 100W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Mission LX-4 MKII: bi-amping; Jamo S 807: Atmos drivers. Mission LX-4 MKII sits in a wider range (10 models), so a matched surround system is easier later. |
| Price | B | Jamo S 807 is cheaper - $519 against $599, about 13% less. |
A Mission LX-4 MKII 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?
Jamo S 807 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. Match it to your room: we rate Mission LX-4 MKII 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.
