Definitive Technology SuperCube Reference Bedienungsanleitung

roducing prodigious bass in a space the size of Trinity

Church means moving some serious air.In previous instal-

lations, Marshall & Ogletree used subwoofers that resem-

bled refrigerators more than speakers. Standing 8 x 4 x 3 feet, the large

cabinets housed twin 15-inch drivers powered by 100-watt amplifiers.

While these speakers could reproduce an organ’s 16-Hz notes, they

took up so much space that installation proved challenging.

Douglas Marshall explained that he and David Ogletree prefer

to use “a multiplicity of subs, both for power and for individual note sep-

aration. So, space can become a real problem. Those huge subs

weren’t practical to use this way in most rooms.”

At a recent Marshall & Ogletree installation in Charlotte,

North Carolina, “we barely would’ve had room for one of them in the

organ chambers,” said Marshall, “and you would’ve had to remove

some of the pipe organ to get it in.” With the Trinity installation, the

organ designers turned to Definitive Technology for a solution.

Def Tech’s Sandy Gross elaborated:

“Marshall & Ogletree wanted a rela-

tively small powered sub that could

produce large amounts of energy

below 16 Hz. Reliability was also

important. The church was just totally

overdriving our SuperCube Reference

subs — which was understandable,

since the Reference had been

designed for use in homes, and

producing that same sound-pressure level in a large public space

is entirely different. You’re dealing with possibly 100 times or more

the air volume.

“Creating the Trinity sub was really an engineering exercise for us,”

Gross continued. “Wecame up with a concept that would appear

to be a double version of the SuperCube Reference. Basically it is,

in terms of driver complements, but when you increase the size of the

box and put those drivers into it, you have a whole new entity in

how you can tune it.

“We also developed a new tuning algorithm to optimize this sub, and

it really helped produce the results we’re getting out of it. Another design

challenge was how to get accurate measurements below 20 Hz in an

anechoic chamber, so we developed a new, proprietary process for

chamber calibration. Wealso had to make sure the sub would stay

together, so we developed a new protection circuit, a high-temperature

high-strength adhesive, and a new voice coil, different from those used

in the SuperCube Reference subs. Wealso designed it to perform equal-

ly well standing up or sitting down.”

The result is the SuperCube Trinity Signature, which is 313/4

inches high,18 inches wide, and 18 inches deep, tipping the scales at

175 pounds. The sub includes two 14-inch long-throw drivers coupled

to four 14-inch infrasonic radiators. Powered by a 2,000-watt digital

amplifier, it can produce in excess of 128 dB at 20 Hz and 116 dB at

16 Hz in a normal-sized room. In essence, the Trinity sub delivers

bass powerful enough to move the mind, body,and soul. —J.S.
