Hertz SPL Show SV250.1

Hertz SPL Show SV250

This kit is made specifically for the Hertz SPL Show 10" woofers. These speakers are nothing like conventional car audio type speakers. They are a pro audio design that have a number of distinct advantages in this application.

  • Light Weight Cone Allows for Very High Output
  • Voice Coil Designed for High Frequency Performance (Up to 7 Khz!)
  • Progressive Surround Allows Much Higher Output with Superior Cone Control
  • Very Powerful Motor Structure
  • Extreme High Thermal Limitations

Hertz ST25 Bullet Horn Tweeters

Hertz ST25 HornsExtreme high output in a very compact size. These tweeter horns are the perfect compliment to the Aggressor Pro 100 speaker system. Efficient compression loading horn and a very powerful neodymium motor make these tweeters spectacular performers. Beautiful, bold and brilliant, the ST25 horns are amazingly accurate and capable of unreal levels of output without distortion. These horns are quite effective when mounted next to the 10" woofer in the bag pointing in at the wheel. They can also be mounted in the top of the lids or in the fairing. Multiple sets can be added. Sold in pairs.
