XL Retro - Limited Edition preorder

We are building a limited 100 pieces of this because you asked for it. We brought back the look of the original XL, using the original XL woofers and tweeters, but we added the functionality of the XL3 such as 5 band EQ, stereo image control, and Bluetooth 5.x with APTx.  We are moving to a mass production business model and clearing out existing raw materials by creating something new with them.  This is a preorder while we finish off the  anniversary build of the XX4.  We expect to ship in April 2025

Wireless True Stereo Sound, with adjustable stereo width control.  Six electrically and mechanically hand-matched 5.5" woofers and a 4" bass port for bass you can feel as well as hear.  122dB loud at 1 meter distance.  Powerful 16.8V 20,100mAh Lithium battery.  Your playlist amplified anywhere, anytime, no electricity needed.

Built-in 600 Watt RMS (1000W Max) Class A/B 10 channel high fidelity amplifier in a tri-amped or bi-amped arrangement (mode dependent) with 2-way or 3-way active crossovers and analog signal processing for the best sound possible in the lightest package with the longest battery life, and ZERO LATENCY inputs for video use. 

With its massive aluminum front panel serving as the amplifier's heatsink, it is made to play FULL BLAST all day on a hot day without skipping a beat.
