History
What size room are the Sonus Lumina V and Sonus Lumina 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:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)

Drivers
One of the fundamental differences between these two speakers is that Lumina V is a 3-way design whereas the Lumina II is a 2-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.

Lumina V features a 1.15" high definition DAD Tweeter, a 6" Midrange and 2 x 6.5" paper cone Woofer with a Crossover frequency at 260 and 2600 Hz. On the other hand, the Lumina II features a 1.15" high definition DAD Tweeter and 1 x 6" paper cone Woofer with a Crossover frequency at 1800Hz.
Frequency Response
Lumina V has a frequency range of 38-24k Hz whereas Lumina II has a frequency range of 55-24k Hz. With a minimum frequency of 38Hz, the Lumina V can go significantly deeper on the low side and provide stronger bass compared to the Lumina II's min frequency of 55Hz.
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
Lumina V and Lumina II have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Lumina V sensitivity is rated at 90 dB and the Lumina II's is at 86 dB. This 4 dB difference makes the Sonus Lumina V a more sensitive speaker compared to Sonus Lumina II, hence will play louder with the same amount of watts.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Lumina V and the Lumina V can provide this impedance level.

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.
Lumina V can handle a max power of 300 watts RMS, whereas Lumina II has a max power handling value of 150 watts RMS, 150 watts less than the Lumina V.
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
Both Lumina V and Lumina II features dual binding post speaker terminals for bi-amping or bi-wiring.
Sonus Lumina II's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Lumina V has a bottom firing port whereas Lumina II has a front firing ports. Sonus Lumina II's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Sonus Lumina V 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 Sonus Lumina V's and Sonus Lumina II's external dimensions. Sonus Lumina V has external dimensions of 1049.0 x 280.0 x 373.0mm (41.3 x 11 x 14.7inch) whereas Sonus Lumina II has external dimensions of 304.0 x 180.0 x 263.0mm (12 x 7.1 x 10.3inch).
Sonus Lumina V is clearly the larger of the two speakers. Its body is 100mm wider, 745mm taller and 110mm deeper than Sonus Lumina II.
Below you can see the front view size comparison of Sonus Lumina V and Sonus Lumina II 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 Sonus Lumina V is approximately 1044.4cm2 / 161.9inch2 and base area of the Sonus Lumina II is approximately 473.4cm2 / 73.4inch2. The Lumina V requires 121% more surface area than the Lumina II which gives it a small disadvantage on placement in tight spaces.
