Woofer	1 x 4.75-inch	1 x 5-inch

Lumina I features a 1.15" high definition DAD Tweeter and 1 x 4.75" paper cone Woofer with a Crossover frequency at 2000Hz. On the other hand, the 607 S2 AE features a 1" Aluminum Decoupled Double Dome Tweeter and 1 x 5" Continuum Woofer.

Frequency Response

Lumina I has a frequency range of 65-24k Hz whereas 607 S2 AE has a frequency range of 52-28k Hz. With a minimum frequency of 52Hz, the 607 S2 AE 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 Bookshelf class in our database.

Min

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 I is a 4 ohms speaker compared to the 607 S2 AE which has a nominal impedance of 8 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 Lumina I can provide this impedance level.

These two speakers also have different sensitivity levels. Lumina I sensitivity is rated at 88 dB and the 607 S2 AE's is rated at 84 dB.

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 I and 607 S2 AE have the same power range of 30-100 watts.

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.

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 I's and B&W 607 S2's external dimensions. Sonus Lumina I has external dimensions of 280.0 x 148.0 x 213.0mm (11 x 5.8 x 8.4inch) whereas B&W 607 S2 has external dimensions of 301.0 x 166.0 x 232.0mm (11-13/16 x 6-1/2 x 9-1/8inch).

B&W 607 S2 is clearly the larger of the two speakers. Its body is 18mm wider, 21mm taller and 19mm deeper than Sonus Lumina I.

Below you can see the front view size comparison of Sonus Lumina I and B&W 607 S2 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 I is approximately 315.2cm² / 48.9inch² and base area of the B&W 607 S2 is approximately 385.1cm² / 59.7inch². The Lumina I requires 18% less surface area than the 607 S2 AE 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 Sonus Lumina I weighs 4.40kg / 9.7lbs and the B&W 607 S2 weighs 4.70kg / 10.3lbs. This makes the 607 S2 AE 7% heavier than the Lumina I.

Verdict

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	B	B&W 607 S2 digs deeper - 52Hz against 65Hz.
Amplifier needs	evenly matched	Similar sensitivity (84dB vs 84dB) - both want much the same power.
Amplifier match	B	B&W 607 S2 is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it.
Headroom	evenly matched	Similar power handling (100W vs 100W).
Size	depends	Sonus Lumina I is easier to place; B&W 607 S2 is bigger, which usually goes with fuller bass. Your room decides.
Expandability	depends	Sonus Lumina I: bi-amping; B&W 607 S2: bi-amping.
Price	B	B&W 607 S2 is cheaper - $799 against $899, about 11% less.

A Sonus Lumina I B B&W 607 S2
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?

B&W 607 S2 is the easier recommendation: it leads on most of the measured areas and costs less. Take Sonus Lumina I if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 65Hz anyway, so judge these on the other rows instead. If your amplifier is modest, vintage or valve-based, B&W 607 S2 is the safer partner - the other will want more current or more watts to sound its best.

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.
