Wisdom Audio’s L150i Reference In-Wall Speaker

Carson City, NV — Wisdom Audio’s new L150i reference line source in-wall speaker system is now shipping. The L150i is the tallest line source within the new multi award-winning Sage Series. The L150i will also make its debut at the 2009 Consumer Electronics Show (CES), held in Las Vegas, Nev. from Jan 8-11 at The Venetian, booth 30-235. 

“We could not be more gratified with how well the L150i was received by our customers and the media alike during last month’s CEDIA Expo,” said Mark Glazier, Wisdom Audio president. “The L150i is our highest expression of the core technology and strengths from the Sage Series for those customers that demand the highest level of sonic refinement and performance available in an in-wall speaker.”

The L150i, which has an MSRP of $15,000 each, is available as an in-wall only model and incorporates two all aluminum cabinets and full back box enclosures per channel. Incorporating true line sources of this length is unprecedented among in-wall speakers and makes it ideal for large rooms or those with unique architectural challenges including cathedral ceilings, hard floors, etc., since true line source arrays effectively eliminate floor and ceiling reflections. The large, 76-inch tall line source driver complement allows for high resolution, low distortion, outstanding dynamic range, and sound pressure levels in excess of 115 dB in a two-channel system. The result is genuinely effortless reference quality performance at any volume level.

“The true line source behavior of the L150i exhibits less propagation loss than any conventional loudspeaker, resulting in a vastly enlarged ‘sweet spot’ that is particularly beneficial in any situation with a large seating area,” Glazier continued. “Whether in a media room with a casual seating arrangement or dedicated home theaters with multiple rows of seating, everyone in the audience is treated to ‘money seat’ performance.”

The L150i consists of two 76-inch H x 8-inch W cabinets per channel, with the woofer cabinet crossing over to the mid/high frequency planar magnetic line source cabinet at 275 Hz. The mid/high frequency cabinet builds upon the planar magnetic line source array of the Sage Series’ L75i model, incorporating three proprietary Wisdom Audio-designed and manufactured PMD drivers resulting in a 72-inch true line source, yielding superior resolution, extraordinary dynamic capability, low distortion and wide dispersion.

The low frequency cabinet within the L150i incorporates 12 six-inch high operating pressure woofers. Each woofer cabinet is driven by a single SA-1 amplifier, thereby using a combined 1,000 watts from its two 500-watt amplifier channels for the 12 woofers. Each channel is a two-cabinet system designed to be installed in-wall within four or five inches of each other (flanking a stud).

“This product was conceived partially in response to the strong dealer reaction to our Sage Series and an expressed interest in an even larger, higher end model,” concluded Jon Herron, Wisdom Audio vice president, sales. “The L150i is a true step above our L75i model and addresses the need described by market feedback. It fits within the Sage Series perfectly and supports our goal of offering dealers a unique, high-performance in-wall solution for their most demanding and discriminating customers.”

Sage Series speakers incorporate new generation proprietary thin film planar magnetic drivers which allow for its narrow and shallow physical characteristics, thus permitting the unprecedented possibility of the same driver complement and back box enclosure to be used for such varied applications, ranging from in-wall to freestanding.
