Built for Midrange Performance

One of the biggest mistakes in car audio is expecting a single speaker to do everything.

The PRO-X6.4BMSL focuses on the most important frequencies in music:

• Vocals
• Guitars
• Drums
• Brass instruments
• Midrange detail

This makes it ideal for:

• SPL systems
• Door speaker arrays
• Pro audio builds
• Competition audio systems
• High-output daily drivers

When paired with dedicated tweeters and subwoofers, the result is an incredibly dynamic and powerful soundstage.

High Power Handling

The PRO-X6.4BMSL offers:

• 250 Watts RMS
• 500 Watts Max Power

This allows it to handle substantially more power than traditional factory replacement speakers.

Compared to common OEM replacements that typically handle 30–60 watts RMS, the DS18 is built for serious amplifier power.

Benefits include:

• Increased volume capability
• Reduced distortion
• Greater dynamic range
• Better performance under heavy load

For enthusiasts running large multi-channel amplifiers, this power handling is a major advantage.

MIDRANGE THAT HANDLES IT ALL – A mid-range driver that may answer the call to care for the most significant a part of the audible sound spectrum. A speaker that sounds great with just instrumentals and, even better with vocals.

High-Temperature Voice Coil Technology

At the heart of the speaker is a:

1.5-Inch CCAW Voice Coil

CCAW (Copper-Clad Aluminum Wire) provides:

• Lower moving mass
• Improved efficiency
• Better thermal management
• Increased durability

The high-temperature design allows the speaker to withstand the heat generated during extended high-volume listening sessions.

That’s especially important when you’re spending hours at a car show demo lane trying to shake nearby license plates loose.

POWER YOU CAN COUNT ON – The PRO-X6.4BMSL delivers an impressive 500W Max Power with 250W RMS at 4 Ohms, enough to tackle a full range of audio.
HIGH-QUALITY VOICE COIL – 1.5” high-temperature CCAW voice coil can care for extreme heat and handle its structural integrity meaning long life out of your speakers.

Slim Mounting Design

One of the standout features of the PRO-X6.4BMSL is its slim profile.

Benefits include:

• Easier installation
• Improved fitment in factory doors
• More flexibility for custom builds
• Reduced clearance issues

This makes the speaker popular among:

• Trucks
• Jeeps
• Custom door panel builds
• Show vehicles

The Aluminum Bullet Advantage

The distinctive red aluminum phase plug isn’t just for appearance.

The phase plug helps:

• Improve midrange dispersion
• Reduce distortion
• Increase efficiency
• Improve cooling around the voice coil

It also gives the speaker the aggressive pro-audio appearance that many enthusiasts love.

Let’s be honest—car audio people enjoy showing off their speakers almost as much as hearing them.
