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

Listening Environment*	Sonus Lumina V	Sonus Lumina I
Near-field	Bad	Average
Small Room	Poor	Good
Mid-size Room	Average	Average
Large Room	Good	Poor
Very Large Room	Average	Bad

(* Approximate Room sizes: Small < 100sq. ft / 9 m², Mid-size: 100-220 sq. ft / 9-20 m², Large 220-400 sq. ft / 20-36 m², Very Large: > 400 sq. ft / 36 m². 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 I 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.

Tweeter	1.15-inch	1.15-inch
Midrange	1 x 6-inch	-
Woofer	2 x 6.5-inch	1 x 4.75-inch

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 I features a 1.15" high definition DAD Tweeter and 1 x 4.75" paper cone Woofer with a Crossover frequency at 2000Hz.

Frequency Response

Lumina V has a frequency range of 38-24k Hz whereas Lumina I has a frequency range of 65-24k 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 I's min frequency of 65Hz.

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.

Average

Median

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 I 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 I's is at 88 dB. This 6 dB difference makes the Sonus Lumina V a more sensitive speaker compared to Sonus Lumina I, 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 I has a max power handling value of 100 watts RMS, 200 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.

Input Type and Bi-Amping / Bi-Wiring

Both Lumina V and Lumina I features dual binding post speaker terminals for bi-amping or bi-wiring.

Sonus Lumina I's Binding post terminals allows Bi-amping or bi-wiring

Cabinet Type and Port Position

Lumina V has a bottom firing port whereas Lumina I has a front firing ports. Sonus Lumina I'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 I'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 I has external dimensions of 280.0 x 148.0 x 213.0mm (11 x 5.8 x 8.4inch).

Sonus Lumina V is clearly the larger of the two speakers. Its body is 132mm wider, 769mm taller and 160mm deeper than Sonus Lumina I.

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 I is approximately 315.2cm² / 48.9inch². The Lumina V requires 231% more surface area than the Lumina I which gives it a small disadvantage on placement in tight spaces.

Verdict

Siblings in Sonus faber's Lumina series, so they share a family sound. It comes down to size, output and price.

Area	Better	Why
Bass	A	Sonus Lumina V digs deeper - 38Hz against 65Hz.
Amplifier needs	A	Sonus Lumina V is more sensitive (90dB vs 84dB), so it goes louder on the same amplifier.
Headroom	A	Sonus Lumina V takes more power (300W vs 100W) - more in hand in a big room.
Size	depends	Sonus Lumina I is easier to place; Sonus Lumina V is bigger, which usually goes with fuller bass. Your room decides.
Type	depends	A Passive Floor-standing against a Passive Bookshelf - a different job rather than a better one.
Expandability	depends	Sonus Lumina V: bi-amping; Sonus Lumina I: bi-amping.
Price	B	Sonus Lumina I is cheaper - $899 against $2,799, about 68% less; arguably a different class.

A Sonus Lumina V B Sonus Lumina I
depends neither is better in the abstract - it turns on your room, placement 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?

The usual trade-off: Sonus Lumina V measures better, Sonus Lumina I costs about 68% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 65Hz anyway, which makes the cheaper Sonus Lumina I much easier to justify. Match it to your room: we rate Sonus Lumina V the better fit for a large room and a very large room, and Sonus Lumina I for near-field listening and a small room.

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.
