"With 2 6.5 inch side mounted woofers playing all the way up to 320 hz, placement is certainly gonna be touchy. This may be the reason they did not sell, and are discontinued, and being blown out ?"
There are a lot of assumptions in that sentence that may not be correct. Doing a quick back of the envelope calculation, the Loft 50 is essentially an eight inch woofer, five inch midrange, and one inch tweeter loudspeaker.
However, the Loft 50 would seemingly improve upon a basic 8" x 5" x 1" design due to its modified configuration. For example, the stacked configuration of the 4" drivers will give better horizontal dispersion in the midrange over a standard 5" driver, while also giving reduced vertical dispersion. This should result in better horizontal imaging while reducing the amount of unwanted sound reflections from the ceiling and flooring. In other words, as compared to a standard 5" driver, the listener will hear a broader horizontal sound stage while also hearing less interference from vertical sound "bouncing" from the ceiling and floor and back to the listener.
The two 6.5" drivers also improve upon a single 8" driver. While having a similar radiating area, by mounting the two separate drivers in opposition to one another, far less bass vibration will be transmitted to the enclosure to be re-radiated into the listening room. This should noticeably tighten the bass. Further, by broadening the dispersion of the bass, the speaker should be easier to place in a room.
An additional benefit to using these multiple drivers is the spreading of the input power over multiple voice coil and magnet structures.
In my eyes, the L 50 looks to be a clever, well thought out design. My only question is whether the apparently minuscule budget allowed for the bill of goods is sufficient to permit unit to unit consistency. If Harman has thought out the driver technology as well as the speaker design, they could have a killer on their hands, and the rest of the industry some 'splaining to do.
One final point: I'm not aware of any information that indicates the L 50s are being discontinued. It may just take a while to build up enough stock to offer them in the U.S. market.
