Pro Audio Midbass Package Stage 3

Get as LOUD as possible with the PROAUDIO.MB/STG3: the Stage 3 Pro-Audio Midbass Package integrates top-tier components to provide a FULL audio upgrade for any system.

At the heart of this package are four 6.5-inch mid-bass speakers. Engineered with water-resistant carbon fiber cones, DS18’s PRO-CF6.4NR are not only durable but also deliver exceptional sound clarity. The neodymium magnets ensure powerful, efficient performance, capable of handling up to 250W RMS power. These speakers maintain impeccable sound quality with a sensitivity of 95 dB, covering frequencies from 80Hz to 12.5KHz.

Complementing the mid-bass speakers are four DS18’s hybrid drivers/tweeters: the PRO-TWN4. These 3-inch high compression neodymium tweeters are designed for delivering clean high frequencies with an impressive sensitivity of 105 dB. The bass blockers ensures that your tweeters remain protected while providing consistent sound output at lower power levels. With power handling capabilities of up to 70W AES, these tweeters add the perfect high-end scream to your setup.

Driving this powerhouse package is the G3600.4D. Compact yet mighty, this full-range Class D amplifier has a MAX Power of 3600W, and power ratings of 4 x 300W RMS at 4 ohms, 4 x 420W RMS at 2 ohms, and a staggering 2 x 740W RMS at 4-ohm bridge. Integrated high and low pass filters allow you to customize your sound profile, while built-in protections safeguard against short circuits, thermal issues, and voltage spikes.

To complete the setup, the DS18 OFCKIT4 amplifier installation kit provides all necessary components for a seamless installation. Featuring 100% oxygen-free copper (OFC) wiring, this kit guarantees superior conductivity and corrosion resistance, ensuring long-term reliability for amplifiers up to 1800W.

Upgrade with the Stage 3 Pro-Audio Midbass Package to exceed expectations in any environment.

Emma N. ★★★★★

First time running pro audio midbass in my truck and the difference is honestly wild — vocals hit clean even with the volume cranked way up. The stage 3 package really does get as loud as they claim without turning muddy.

Leo ★★★★★

Swapped these into my doors and the punch on kick drums is unreal now, way fuller than my old setup. The Stage 3 package really does push volume without crapping out when I turn it up.

Grace H. ★★★★★

The midbass on these is no joke — kick drums actually punch through the doors now instead of just rattling them. I was worried the install would be a nightmare, but the package went in clean and sounds full at high volume without going muddy.
