Energy Take Classic Speaker System HT Labs Measures

HT Labs Measures

Satellite Sensitivity: 85.5 dB from 500 Hz to 2 kHz
Center Sensitivity: 85.5 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the Take Classic satellite (purple trace), Take Classic subwoofer (blue trace), and the Take Classic 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 satellite’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +2.66/–4.64 decibels from 200 hertz to 10 kilohertz. The –3-dB point is at 111 Hz, and the –6-dB point is at 91 Hz. Impedance reaches a minimum of 4.55 ohms at 351 Hz and a phase angle of –51.78 degrees at 179 Hz.

The center’s listening-window response measures +1.52/–5.71 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +0.87/–6.19 dB from 200 Hz to 10 kHz. The –3-dB point is at 94 Hz, and the –6-dB point is at 86 Hz. Impedance reaches a minimum of 4.49 ohms at 351 Hz and a phase angle of –48.92 degrees at 162 Hz.

The subwoofer’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 30 Hz and the –6-dB point is at 28 Hz. The upper –3-dB point is at 170 Hz with the Low-Pass Filter control set to maximum.—MJP

Hello,

I have to say that this review of the Take Classics is probably the most in-depth and detailed one available, great job! I have a question, and before I go any further, I want to let you know that am not an audiophile, but am taking a great interest in the field. I own a Yamaha RX-A2000 along with the 5.1 take classic speakers.

Based on manufacturer's specs the center's -3dB point is at 110hz and the surrounds at 115hz. According to your measures, the center is at 94hz and the surrounds at 111hz.

Therefore I've set the crossover for my center at 110hz and for the surrounds at 120hz. I am just a bit concerned that I might be loosing some range as the center is rated at 110 and crossover is the exact same, not giving any room to play with.

Is it possible that my system would not rate the same as the one you tested? Could there be a technical difference from one batch to the next of the same speakers?

I just want to make sure I am exploiting the best out of my speakers.

Thank you,

Toomuch
