6.5 2-Way, In-Ceiling, Coaxial, Infinite Baffle Loudspeaker The easy to install FIT652FL is a full-range ceiling loudspeaker with Focused Image Technology. It incorporates a lightweight Aluminum Alloy woofer with a butyl rubber surround and the diffraction-less aluminum dome pivoting Ferrofluid cooled tweeter. The FastLoc grill is a patent pending feature found only at Current Audio. Our design has allowed for the smallest exposed plastic bezel in the industry, truly making it disappear into the mounting surface. The FastLoc grill’s unique patent pending mechanism allows for a quick installation and removal of the grill while securely fastening it in place to all types of mounting surfaces. Due to the unique design the grill will conform to uneven surfaces including popcorn, heavy textured and uneven ceilings. While our competitors have chosen to utilize magnets in their designs thus requiring the use of a steel grill that will rust our design allows us to use corrosion and rust resistant aluminum. The FIT series speakers additionally incorporate the unique Patent Pending Three Dimensional Positioning (3-DP) woofer. This design allows the user to separately adjust the angle, tilt and rotation of the woofer so you can direct the sound where you want it, not where you install it. The Positive Position Lock system (PPL) uses two screws on either side of the woofer that pull the back plane tight and locks the position in place. The Infinite Baffle design makes it the ideal choice for typical applications in open beam attic or enclosed ceilings. Driver Material: Aluminum Cone This was my favorite driver material for years before we perfected the woven carbon fiber material. This is a special aluminum alloy with a hard coat anodized coating. Very low moving mass with high stiffness. The result is a driver that has great detail in the midrange. The bass is very tight and detailed. This driver is “warm” sounding, neutral and detailed. Tweeter Material: Aluminum Dome Tweeter This tweeter dome material is not your normal aluminum dome. It is a specially produced aluminum alloy with a hard coat anodized coating. This dome allows for minimum distortion of the upper dome in the higher frequency ranges. The majority of the energy of the tweeter dome comes from the largest diameter of the dome’s sphere. The majority of the acoustical energy does not come from the center of the dome as most people think. In fact, the center of the dome’s sphere usually breaks up and causes distortion.
