lot of speaker for the money. In

terms of performance, the compe-

tition at this price level gets pretty

intense, so they’d better sound

flippin’ awesome, too.

What exactly do you get for the

money? The BP7000

SC

is tall, stand-

ing 52.5 inches high, but the 8.9-

inch width and 16.6-inch depth

mean that it takes up only a bit

more than a square foot of floor

space. You might worry that such

a tall, slender speaker would be

unstable or easy to knock over.

Fear not: The BP7000

SC

’s 100-

plus pounds keep it locked solidly

in place, whether you use feet or

spikes ( both are included). Here’s

a tip: Lest you want to risk being

nailed to the floor like the silver-

masked opponent who battled

Maximus in Gladiator, be careful

when you move the BP7000

SC

with

the spikes in place. Your best bet

is to position the speaker first and

then install the spikes. In trade-

mark Def Tech fashion, a sleek,

’s

private parts, except for the

exposed back panel, which con-

tains the speaker connections,

LFE input, subwoofer volume con-

trol, and amp-cooling vanes. The

usual hard-edged end caps are

replaced with gorgeous, softly

sculpted ones. Even though it’s a

modest design change, it makes

quite a difference, giving the

speakers a much more-prestigious

look. On the other hand, while the

spikes certainly do the job, they’re

a little wimpy compared with the

rest of the speaker.

The mirror-imaged, bipolar

BP7000

SC

s include powered

subwoofers. Although a 1-inch

aluminum dome tweeter and two

6.5-inch bass/midrange drivers

reside on both the front and back

of the tower, the front and rear

drivers use separate and different

types of crossovers. The BP7000

SC

is designed to achieve more-linear

frequency- and phase-response

curves and to be easier to drive

with most amplifiers. The sub-

woofer section in each BP7000

SC

is the equivalent of a Def Tech

SuperCube Reference subwoofer.

One 14-inch long-throw SuperCube

active woofer is mounted in the

tower’s relatively acoustically

small lower section, along with

two 14-inch passive drivers. An

1,800-watt digitally coupled Class D

amplifier powers the trembling

trio. The SuperCube technology is

one of the latest and, in my opin-

ion, most successful methods of

producing prodigious amounts of

bass in a small enclosure. Just to

give you an idea of what a leap

this is, Def Tech’s previous top-

of-the-line BP3000

TL

incorporates

a single 18-inch woofer with a

1,000-watt amp. Don’t think that

hooking up such a beast is a prob-

lem or requires special expertise.

HT Labs Measures: Definitive Technology BP7000SC SuperTower
Speaker System
This graph shows the quasi-anechoic (employing close-miking of all woofers)
frequency response of the BP7000SC L/R (purple trace), C/L/R3000 center
channel (green trace), and BPVX/P surround (red trace). All passive loud-
speakers were measured at a distance of 1 meter with a 2.83-volt input
and scaled for display purposes.

The BP7000SC’s listening-window response (a five-point average of

axial and +/–15-degree horizontal and vertical responses) measures
+2.50/–3.64 decibels from 200 hertz to 10 kilohertz. The –3dB point is at
22 Hz, and the –6dB point is at 21 Hz. Impedance reaches a minimum of
2.92 ohms at 424 Hz and a phase angle of –37.82 degrees at 154 Hz.
Sensitivity averages 91 dB from 500 Hz to 2 kHz.

The C/L/R3000’s listening-window response measures +2.39/–1.43 dB

from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal
responses measures +2.73/–1.65 dB from 200 Hz to 10 kHz. The –3dB
point is at 37 Hz, and the –6dB point is at 33 Hz. Impedance reaches a
minimum of 2.16 ohms at 310 Hz and a phase angle of –33.93 degrees at
170 Hz. Sensitivity averages 93.5 dB from 500 Hz to 2 kHz.

The BPVX/P’s three-face averaged response measures +3.42/–3.02 dB

from 200 Hz to 10 kHz. The –3dB point is at 38 Hz, and the –6dB point
is at 35 Hz. Impedance reaches a minimum of 2.73 ohms at 457 Hz
and a phase angle of –47.74 degrees at 224 Hz. Sensitivity averages
91 dB from 500 Hz to 2 kHz.—AJ
