The best of the pro audio and car audio worlds are combined in this compact 8″ speaker! The 8CX380-4 SLIM’s coaxial speaker has a built-in tweeter driver, an innovative design that delivers amazing sound clarity.

For a countless number of applications that require high output sound in small locations where conventional drivers wouldn’t fit, we have carefully blended a super tweeter with our PRO Audio shallow midrange speaker in a compact package. This is the greatest 8″ compact coaxial for custom systems that is both small and loud.


  • Slim Design – Perfect for tight space applications that require PRO Audio sound quality in small areas where conventional drivers wouldn’t fit.
  • Built-in driver tweeter with in-line capacitor attenuates perfectly with the speaker, giving you a rich musical response.
  • 380 Watts RMS Music Power Handling, with a 97 dB Sensitivity, capable of generating a lot sound with a small cone!
  • Grill and Mounting Screws Included
  • Also available in 6.5″- 6CX380-4 SLIM

By combining elements from the PRO Audio and Car Audio segments, we have developed a new type of highly efficient coaxial that is able to give high levels of output in compact spaces.Its slim design makes this coaxial the perfect speaker, allowing it to be utilized in endless ways.

Loud and clear vocals are all within 2.76′′ of mounting depth without sacrificing quality or performance.

Its specially composed spider reduces distortion on midbass frequencies, and its double roll surround keeps cone travel linear, while its premium tinsel lead wire is capable of high temperatures.

This makes this speaker not only unique but also gives it all high-performance characteristics and high-quality components, providing exceptional clarity, detail, and dynamic sound.

8CX380-4-SLIM Frequency Response
  *Nominal power handling is defined as the maximum RMS power that the speaker can handle in a 2-hour test with a pink noise with 6dB of crest factor and a bandpass filter with 12db/oct tuned in its usable frequency range. **Continuous Program Power (RMS) is the maximum power that the speaker can handle considering a regular musical program using our recommended filters, this power can be used to define the optimum amplifier power to avoid a clean signal without clipping or saturation. ***Max Peak Power is the maximum power operation for the speaker, this power is allowed just for a few fractions of a second, usually found just on the peaks of the music. Keeping this power for a little longer timer will damage the speaker.
