The Level 4 m4 is a step forward in SQ and heat dissipation vs the last generation model (m3). It now comes with a 2.5mm Aluminum Shorting ring (demodulation ring) to help reduce inductance in the motor. This can help with power compression.
It also acts as an internal heatsink by pulling heat from the windings into the aluminum ring and direct to coil venting cycles air across the coil windings and aluminum shorting ring at the same time cooling them simultaneously.
Newly tooled Motor boots with the DC Logo and LV4 logo embossed on them
With fantastic power handling and smashing lows its hard to beat.

I ordered 2 level 4 10s stock builds. After listening to them for a day or 2 I ordered a single level 4 12 with the upgraded xl spl voice coil and spider package. Again sounds amazing and it’s not even broken in yet. I had to call the customer service tech line for a question about box specs and port area. The guy actually took the time and explained things to me vs other companies will answer your questions and kinda make you feel your bothering them. I will be buying dc audio subs for now on thanks
Dc audio for the win !!! We don’t use any other woofers in our builds
Very happy with DC products. I love them in any build looking for real bass! The customer service is exceptional!
These subs look really good. This is my 1st DC Audio sub. I purchased 2. They took the time out to build these and ship them in no time. I haven’t gotten a chance to hear them just yet. Next step is building the box.
