This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the Imagine XB satellites (purple trace), SubSeries 125 subwoofer (blue trace), and Imagine XC center channel (green trace). All passive loudspeakers were measured with grilles at a distance of 1 meter with a 2.83-volt input and scaled for display purposes.

The Imagine XB’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +2.67/–3.16 decibels from 200 hertz to 10 kilohertz. The –3dB point is at 57 Hz, and the –6dB point is at 50 Hz. Impedance reaches a minimum of 4.30 ohms at 193 Hz and a phase angle of –54.10 degrees at 111 Hz.

The Imagine XC’s listening-window response measures +2.53/–4.27 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +1.90/–4.20 dB from 200 Hz to 10 kHz. The –3dB point is at 71 Hz, and the –6dB point is at 55 Hz. Impedance reaches a minimum of 4.84 ohms at 195 Hz and a phase angle of –48.91 degrees at 106 Hz.

The SubSeries 125’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3dB point is at 38 Hz and the –6dB point is at 35 Hz. The upper –3dB point is at 129 Hz with the Crossover switch set to External.—MJP

If you are reading a audiophile level publication( or this website),the name Bose shouldn't even be in your vocabulary. I used to sell the crap ( mainly our store sold it because it has huuuuuuge margins , and also to pawn off on idiots off the street looking for Bose, who didn't have the time or the ears to be upsold to quality equipment), and a 700 dollar accoustimass system, cost the store 138 dollars, and supposedly cost Bose under 40 dollars to make. It is GARBAGE! Their success relies strictly in brand recognition with people who don't know better. No Highs, no lows......MUST BE BOSE!!

Bose.... Ya love them or you hate them. Oddly enough, both comments above are both right and wrong.
Bose happened to be one of the most recognized hp and speaker brands ... Outside of the specialty industry. Most lay-consumers perceive Bose to be the pinnacle of performance and design. Where's as most consumers who venture inside our industry rarely take the brand seriously.
As a result, Bose prefers to sell directly to consumers. Or to position their products ' inside' the industry as to avoid any direct performance comparisons. They have done a brilliant job of product positioning. As for the actual product itself, I'm not sure who would buy the brand based on fit, finish, construction quality, or even sound quality.
Suffice to say that Bose knows where their sandbox is, and are very careful to not venture to far inside the real AV industry.
