Definitive Technology BP-8080ST Speaker System HT Labs Measures

HT Labs Measures

L/R Sensitivity: 91.5 dB from 500 Hz to 2 kHz

Center Sensitivity: 92.5 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the BP-8080ST L/R (purple trace) and CS-8080HD 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 BP-8080ST’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +3.12/–2.11 decibels from 200 hertz to 10 kilohertz. The –3-dB point is at 35 Hz, and the –6-dB point is at 33 Hz. Impedance reaches a minimum of 4.58 ohms at 273 Hz and a phase angle of –34.63 degrees at 179 Hz.

The CS-8080HD’s listening-window response measures +3.06/–3.01 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +3.45/–3.74 dB from 200 Hz to 10 kHz. The –3-dB point is at 41 Hz, and the –6-dB point is at 39 Hz. Impedance reaches a minimum of 5.24 ohms at 284 Hz and a phase angle of –37.97 degrees at 183 Hz.—MJP

A common problem is the creation of a ground loop (buzzing) in speakers if you use an amplifier and a subwoofer (another amp) on the same circuit (breaker)--> they "fight" for control of the ground. So my question is do the BP-8080STs create a ground loop if they (with two amps) are on the same circuit as the amplifier in your room?

How do the BP-8080ST compare to the Mythos ST for music and movie?

I bought the definitive mythos bipolar towers, center and surround. The manual says to configure manually because automated programs won't properly calibrate bipolar speakers.

Is this true for Audyssey? I read in the review that you liked using a trusted auto-setup!
