What size room are the Magnepan LRS+ and Jamo C 97 II 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:

Drivers
One of the fundamental differences between these two speakers is that LRS+ is a -way design whereas the C 97 II is a 3-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.

LRS+ features a " Tweeter and x " Woofer. On the other hand, the C 97 II features a 1" Tweeter, a 6" Midrange and 3 x 6" Composite Woofer.
Frequency Response
LRS+ has a frequency range of 50-20k Hz whereas C 97 II has a frequency range of 32-24k Hz. With a minimum frequency of 32Hz, the C 97 II can go significantly deeper on the low side and provide stronger bass compared to the LRS+'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 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
LRS+ is a 4 ohms speaker compared to the C 97 II which has a nominal impedance of 6 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the LRS+ can provide this impedance level.
These two speakers also have different sensitivity levels. LRS+ sensitivity is rated at 86 dB and the C 97 II's is rated at 89 dB. This 3 dB difference makes the Jamo C 97 II a more sensitive speaker compared to Magnepan LRS+, hence will play louder with the same amount of watts.

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 Magnepan LRS+'s and Jamo C 97 II's external dimensions. Magnepan LRS+ has external dimensions of 1219.2 x 330.2 x 25.4mm (48 x 13 x 1inch) whereas Jamo C 97 II has external dimensions of 1070.0 x 248.0 x 402.0mm (42-1/8 x 9-3/4 x 15-13/16inch).
Jamo C 97 II is 82.2mm narrower and 149.2mm shorter than Magnepan LRS+ but it is also 376.6mm deeper.
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 Magnepan LRS+ is approximately 83.9cm2 / 13.0inch2 and base area of the Jamo C 97 II is approximately 997.0cm2 / 154.5inch2. The LRS+ requires 92% less surface area than the C 97 II which gives it a small advantage on placement in tight spaces.
