Proficient In-Walls Pack Dual 6 1/2” Woofers into Compact LCR Speakers
Mounted horizontally, the high-performance IW650 and IW625 LCR speakers fit between two studs.
In-wall LCR speakers for flat-panel displays are a dime-a-dozen. But the center channel is either too big to fit between two studs, or too wimpy to fill a decent-sized room.
Proficient Audio is solving these deficiencies with the IW650 and IW625, which improve upon the company’s IW550 and IW525.
The new speakers feature dual 61/2-inch woofers, yet they still fit horizontally within a 16-inch stud bay. It’s no small feat to pack so much power into such a compact space, says Proficient president Keith Marshall.
“With 2 by 6 ½, that’s 13 inches right there,” he says. Then you need the mounting hardware and other speaker accoutrements.
To compress the size of the speaker, Proficient “staggered where the tweeter sits, and we made the preconstruction bracket thinner than we normally would,” Marshall says.
Marshall believes Proficient will be the first company to demonstrate this type of speaker at CEDIA Expo 2008. “No one had one last year,” he says. “Everybody has dual 5 ¼ speakers, but to have a step-up like this is a big deal because of the performance in terms of sound pressure level (SPL).”
Bass response is improved dramatically, Marshall claims, due to a 40-percent increase in surface area of the woofer cones. “There is an enormous difference,” he adds. “You can put them into bigger rooms.”
The IW650 ($475 each) features two 6 1/2‐inch Kevlar‐cone woofers and a 1‐inch aluminum dome tweeter. The IW625 ($400) uses two 6 1/2‐inch graphite‐cone woofers with a 1‐inch soft dome tweeter.
Dispersion is improved because the tweeter is positioned between and in close proximity to the woofers. In both models, the tweeter can be pivoted to direct the high frequencies as desired.
Frequency response of the IW650 is 50 Hz to 20 kHz with power handling of 150 watts. The IW625 frequency response is 55 Hz to 20 kHz and power handing is 125 watts. Both speakers have 8 ohm impedance and 90 dB sensitivity, making them easy for even relatively low‐powered amplifiers to drive.
And both allow contouring of the response to suit the acoustic environment via switches that provide ±3dB of trim for bass and treble.
The IW Series is shipping now at a suggested retail prices are $475 each for the IW650 and $400 each for the IW625.
