4288 Stereo Loudspeaker System (PAIR)
After receiving a TEC Award nomination for the 4288 in 2012 we challenged ourselves to make the 4288 MK II even better. We started with a requested upgrade to the amplifier section by adding 3.9dB to the front end of gain without sacrificing any headroom. In fact we improve what was already outstanding headroom. Once that was accomplished we focused on the speaker components.
We upgraded all the capacitors in the mid-high crossover network to audiophile grade Polypropylene capacitors. Polypropylene caps are known for the excellent audio quality and reliability. They impart a clear and smooth top end and enhance the dual concentric driver’s performance.
Then we turned our attention to the custom 8in. woofer. We replaced the original single spider woofer with a dual spider unit for improved excursion control and linearity. Along with the spider upgrade we improved the voice coil, effectively tripling the power handling power capability of the woofer.

To top it all off we have sculpted a new and exciting finish for the 4288 MK II. The cabinet in now laminated with black anodized aluminum with chamfered and stained edges. It’s a unique finish matches the awesome performance of the 4288. “
