About the Boston Acoustics ISTS
If the music in your car leaves you uninspired, here's a great way to brighten things up. Install Boston Acoustics' ISTS tweeters in a good location in your interior, and you'll hear a whole new world open up. These 1" tweeters add the high-frequency details that create a stronger stereo image and give you more realistic sound.
These dome tweeters are made from Kortec®, a strong, lightweight material that's well-suited for high-frequency reproduction, so your highs can really sparkle without sounding shrill. The included crossovers prevent lower frequencies from reaching the tweeters and compromising sound quality. The package includes hardware for flush-, surface-, and angle-mounting your tweeters, so you can choose the best configuration for your soundstage.

Features
Overview: The Boston Acoustics IS Type-S (ISTS) Imaging System contains two 1" tweeters, two passive crossovers, speaker wire, and mounting hardware. The Boston Acoustics ISTS optimizes the soundstage height in your vehicle and easily incorporates into any existing car audio system.
1" Tweeters: The tweeters feature 1" Type S-1 Kortec domes for smooth high frequency response and linearity. Kortec is a specially engineered material with the rigidity of a composite dome and the smoothness and detailed response of cloth.
Mounting Cups: The supplied Quick-fit mounting cups simplify tweeter installation. The tweeters come with flush, surface, and angle mount brackets.
Passive Crossovers: On each tweeter crossover, you can adjust the tweeter output by -3, -6, or -9 dB. The crossover's top-cover is removable to adjust tweeter output and to make speaker connections. A small philips-head screwdriver is required to connect the included speaker wire to the crossovers.
Speaker Wire: The Boston Acoustics ISTS includes two 5' lengths of speaker wire to attach the tweeters to the crossovers. The speaker wire features male and female quick-slide connectors.
