Tower Speaker Reviews

Definitive Technology Atmos-Enabled BP-8060ST Speaker System Review Test Bench

Test Bench

Tower Sensitivity: 88.5 dB from 500 Hz to 2 kHz

Center Sensitivity: 89 dB from 500 Hz to 2 kHz

Elevation Module Sensitivity: 84.5 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the BP-8060ST towers (purple trace), CS-8060HD center channel (green trace), and A60 elevation module surround (red 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-8060ST’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +2.66/–2.26 decibels from 200 hertz to 10 kilohertz. The –3dB point is at 39 Hz, and the –6dB point is at 36 Hz. Impedance reaches a minimum of 4.68 ohms at 338 Hz and a phase angle of –50.34 degrees at 213 Hz.

The CS-8060HD’s listening-window response measures +3.56/–2.15 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +4.23/–2.09 dB from 200 Hz to 10 kHz. The –3dB point is at 40 Hz, and the –6dB point is at 37 Hz. Impedance reaches a minimum of 5.26 ohms at 295 Hz and a phase angle of –45.38 degrees at 183 Hz.

The A60’s driver-axis response measures +4.15/–5.57 dB from 200 Hz to 10 kHz. The –3dB point is at 136 Hz, and the –6dB point is at 113 Hz. Impedance reaches a minimum of 6.91 ohms at 302 Hz and a phase angle of –42.08 degrees at 179 Hz.—MJP

I have a 5.1.2 Atmos setup with 8060/A60's in the front, 8040hd center, and def tech in-ceiling rear surrounds, with the Pioneer Elite SC-85 Atmos receiver. My setup sounds terrific, and the Atmos height effects are amazing, especially with helicopters and planes flying overhead. I agree the 8060's sound great for both music and movies, just wondering why not 5 stars for performance?

I had a def tech system of 4- 2006's and the 2500 C/L/R for about 3 years and I was never happy with it. If I had a penny for how many times I re-arranged it I'd be a millionaire. Perhaps it was my room that is 12X14 with 8' ceiling and 2 windows, a french door, and open alcove into the kitchen, plus a tiled floor. I'm surprised my wife didn't divorce me:). I finally went back to my old Atlantic Tech. satellite system with 2 subs. The difference was night and day. Ultimately I sold the Def Techs. and bought a new Pioneer Elite VSX52 receiver. I know I lost money on the deal but just wanted to get rid of the def techs. BTW re: VSX-52 this is one receiver that runs hot, and not the first Pioneer to do so. My solution was to install a laptop cooler pad on top of the receiver connected to my tv. Problem solved. The other night I temp. removed the pad and cranked up Pacific Rim (7.1). Fifteen minutes later the receiver was absolutely hot (not warm) to the touch. And the receiver placement is not enclosed in a cabinet.
