The CoAx-12 pair delivers professional-grade sound reproduction for musicians, DJs, and sound engineers building custom speaker cabinets or replacing worn drivers. These 12-inch coaxial speakers feature an integrated T-yoke design that positions the high-frequency driver at the center of the woofer cone.

Each speaker handles 300 watts RMS (600 watts peak) with 8-ohm impedance, providing the power handling needed for live performance applications. The coaxial design eliminates phase alignment issues between drivers, creating consistent sound coverage across your listening area.

The 50Hz-18kHz frequency response covers the full range of vocals and instruments, while 97dB sensitivity ensures efficient power conversion from your amplifier. The pressed steel chassis and paper cone with cloth surround deliver reliable performance in demanding environments. Dual voice coils — 3-inch for the low frequency driver and 1.75-inch for the high frequency — handle power distribution effectively.

These speakers work well for live sound reinforcement in venues up to 200 people, studio monitors, DJ setups, and karaoke systems. The 11¾-inch cutout diameter fits standard 12-inch cabinet openings, while eight mounting slots provide secure installation options.

Each speaker measures 12¼ inches in diameter with 8-inch overall depth and weighs 16.4 pounds. Standard speaker wire connections make integration straightforward with any amplifier or powered mixer. Seismic Audio backs each pair with a one-year warranty and direct technical support.

Frequently Asked Questions

What size venues can these coaxial speakers handle?

The CoAx-12 pair works effectively for venues up to 200 people when properly powered and positioned. Each speaker's 300-watt RMS handling and 97dB sensitivity provide sufficient output for small to medium live music venues, churches, school auditoriums, and DJ events. For larger venues or outdoor events, consider adding a subwoofer or using multiple pairs.

Do I need a subwoofer with these coaxial speakers?

These speakers reproduce frequencies down to 50Hz, covering most bass content for vocals and many instruments. However, adding a subwoofer enhances the low-end response for bass-heavy music genres, kick drums, and electronic music. The coaxial design makes them excellent full-range speakers when a subwoofer isn't practical or necessary.

What amplifier power do I need for these speakers?

Match these speakers with amplifiers delivering 200-400 watts RMS per channel at 8 ohms for optimal performance. The 300-watt RMS rating means they can handle substantial power, while the 97dB sensitivity ensures they'll produce good volume even with lower-powered amplifiers. Avoid exceeding 600 watts peak to prevent damage.

Can these replace blown speakers in existing cabinets?

Yes, these work as direct replacements for most 12-inch speakers with the standard 11¾-inch cutout diameter. The eight mounting holes and ¼-inch slot dimensions fit common cabinet designs. Check your existing speaker's impedance and power ratings to ensure compatibility with your amplifier setup.

How do I wire these coaxial speakers to my amplifier?

Connect standard speaker wire from your amplifier's speaker outputs to the positive and negative terminals on each speaker. The coaxial design means one set of connections powers both the woofer and tweeter internally. Use 12-gauge or thicker speaker wire for runs longer than 25 feet to maintain power transfer efficiency.
