What size room are the JBL Stage A170 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:

A170 features a 1" aluminum HDI (High Definition Imaging) waveguide Tweeter and 2 x 5.25" Polycellulose Woofer. 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
A170 has a frequency range of 44-40k 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 A170's min frequency of 44Hz.
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
A170 is a 6 ohms speaker compared to the S 807 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. A170 sensitivity is rated at 89 dB and the S 807's is rated at 90 dB. This 1 dB difference makes the Jamo S 807 a more sensitive speaker compared to JBL Stage A170, 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.
A170 can handle a max power of 200 watts RMS, whereas S 807 has a max power handling value of 100 watts RMS, 100 watts less than the A170.
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
A170 features 5-Way 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 JBL Stage A170's and Jamo S 807's external dimensions. JBL Stage A170 has external dimensions of 977.0 x 267.0 x 331.0mm (38-7/16 x 10-1/2 x 13inch) whereas Jamo S 807 has external dimensions of 915 x 191 x 252 mm (36 x 7-1/2 x 9-15/16 inch).
JBL Stage A170 is clearly the larger of the two speakers. Its body is 76mm wider, 62mm taller and 79mm deeper than Jamo S 807.
Below you can see the front view size comparison of JBL Stage A170 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 JBL Stage A170 is approximately 883.8cm2 / 137.0inch2 and base area of the Jamo S 807 is approximately 481.3cm2 / 74.6inch2. The A170 requires 84% 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 JBL Stage A170 weighs 14.37kg / 31.6lbs and the Jamo S 807 weighs 11.80kg / 26lbs. This makes the A170 22% heavier than the S 807.

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 | evenly matched | Much the same reach (44Hz vs 42Hz). |
| Amplifier needs | evenly matched | Similar sensitivity (89dB vs 90dB) - both want much the same power. |
| Amplifier match | B | Jamo S 807 is the easier load at 8 ohms. |
| Headroom | A | JBL Stage A170 takes more power (200W vs 100W) - more in hand in a big room. |
| Size | depends | Jamo S 807 is easier to place; JBL Stage A170 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | JBL Stage A170: bi-amping; Jamo S 807: Atmos drivers. JBL Stage A170 sits in a wider range (10 models), so a matched surround system is easier later. |
| Price | B | Jamo S 807 is cheaper - $519 against $600, about 14% less. |
A JBL Stage A170 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?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. Match it to your room: we rate JBL Stage A170 the better fit for a large room, and Jamo S 807 for a small room. In a large or open-plan room, JBL Stage A170 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Jamo S 807 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.
