What size room are the Jamo C 93 II and Polk TSi200 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

C 93 II features a 1" Soft-Dome Tweeter and 1 x 6" Composite Woofer. On the other hand, the TSi200 features a 1" Dome Tweeter and 2 x 5.25" Organic Fiber Woofer with a Crossover frequency at 2500Hz.
Frequency Response
C 93 II has a frequency range of 45-24k Hz whereas TSi200 has a frequency range of 50-24k Hz. With a minimum frequency of 45Hz, the C 93 II can go significantly deeper on the low side and provide stronger bass compared to the TSi200's min frequency of 50Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf 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
C 93 II is a 6 ohms speaker compared to the TSi200 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. C 93 II sensitivity is rated at 86 dB and the TSi200's is rated at 89 dB. This 1 dB difference makes the Polk TSi200 a more sensitive speaker compared to Jamo C 93 II, hence will play louder with the same amount of watts.
Sensitivity
Bookshelf 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.
TSi200 can handle a max power of 150 watts RMS, whereas C 93 II has a max power handling value of 120 watts RMS, 30 watts less than the TSi200.
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
C 93 II features Pair of 5-way binding posts - Gold-plated type posts and TSi200 has a Pair of 5-way binding posts - Gold-plated type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both C 93 II and TSi200 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 Jamo C 93 II's and Polk TSi200's external dimensions. Jamo C 93 II has external dimensions of 350.0 x 200.0 x 259.0mm (13.7 x 7.8 x 10.1inch) whereas Polk TSi200 has external dimensions of 392.1 x 203.2 x 298.5mm (15.4 x 8.0 x 11.7inch).
Polk TSi200 is clearly the larger of the two speakers. Its body is 3.2mm wider, 42.1mm taller and 39.5mm deeper than Jamo C 93 II.
Below you can see the front view size comparison of Jamo C 93 II and Polk TSi200 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 Jamo C 93 II is approximately 518.0cm2 / 80.3inch2 and base area of the Polk TSi200 is approximately 606.6cm2 / 94.0inch2. The C 93 II requires 15% less surface area than the TSi200 which gives it a small advantage on placement in tight spaces.
Here is another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 Jamo C 93 II weighs 6.40kg / 14.1lbs and the Polk TSi200 weighs 7.71kg / 17lbs. This makes the TSi200 20% heavier than the C 93 II.

These sit in different price classes - Jamo C 93 II costs roughly 2.1x what Polk TSi200 does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | A | Jamo C 93 II digs deeper - 45Hz against 50Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (88dB vs 89dB) - both want much the same power. |
| Amplifier match | B | Polk TSi200 is the easier load at 8 ohms. |
| Headroom | B | Polk TSi200 takes more power (150W vs 120W) - more in hand in a big room. |
| Size | depends | Jamo C 93 II is easier to place; Polk TSi200 is bigger, which usually goes with fuller bass. Your room decides. |
| Price | B | Polk TSi200 is cheaper - $279 against $574, about 51% less; arguably a different class. |
A Jamo C 93 II B Polk TSi200
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?
Polk TSi200 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 50Hz anyway, which makes the cheaper Polk TSi200 much easier to justify. Think about the whole system, not just the speakers: the roughly $295 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
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.
