JL Audio TwK-88

Equipped with an advanced 24-bit DSP, the TwK 88 and TwK D8 tuning systems provide the real-time data to bring out the best in your vehicle’s sound system. Whether you’re an audio beginner, passionate enthusiast or dedicated audiophile, TwK DSPs put an amazing set of tuning supertools right at your fingertips. Engineered to deliver world-class system-tuning capabilities in an easy-to-use format, both the TwK 88 and TwK D8 processors offer 8 channels of crystal-clear analog audio outputs plus an unprocessed optical (Toslink device) digital output. The optical output jack lets you expand your system with additional TwK DSPs, if needed.

Great DSP

This product is awesome. takes awhile to configure, but once you configure it it sounds great. I have is paired with Sound Stream Rubicon 5 channel amp. JL tech support was awesome to help me set it for best sound.

Great Processor

Use this after using a signal processor like the FiX 82 or 86. The tunability of this unit is super. Typically, you can setup your system in many different configurations.

Great Deal

I purchased the Twk expecting an open box item. Seemed when i received it was brand new. The box was still sealed and everything was never touched. Would definitely buy again.

TWK 88 is Great!

I have alot of good things to say about this item, But I want to start with the bad - THE PRICE. this thing is too expensive! TO GET TO DO WHAT I WANTED I NEEDED TO BUY THIS AND THE FIX86. IF I COULD FIND THE HELIX DSP, I WOULD OF GOT THAT INSTEAD. SO with that being said, I spent over 1000 on these two items, but they work fine and sound great, easy to program, and have the back up of JL Audio. OVERALL satisfied with them.

Great DSP for a Quality System

Love this DSP. This is my first one and I was able to tune my system exactly how I wanted it. Good for beginners but I can see it could also go in-depth for the more experienced. I highly recommend this and the customer service and shipping was superb.
