...55 Hz - 20 kHz. Sensitivity: 88 dB. Crossover Point: 2 kHz. Crossover Slope: 12 dB. Tweeter Dome Material: Aluminum dome tweeters deliver great sound with increased reliability.
Speaker Surround: Butyl rubber surrounds provide durability and deeper mid-bass impact. Voice Coil: Pure Copper voice coil creates a strong magnetic field with a very thin extrusion. Voice Coil Former: Kapton voice coil former is lightweight and efficiently dissipates heat. Spider: Natural fiber allows flexibility while the infused epoxy gives strength during the manufacturing process. Cone Material: Lightweight thermal-formed polypropylene cones enable faster midrange response.
Surround/Cone Coupling: The cone/surround connection utilizes a high temp adhesive which assure the cone and surround do not separate in high power uses or extremes of weather. Gasket: A textured ABS gasket assures a rigid linear seal to the mounting surface. Tinsel Leads: Highly conductive while remaining flexible during high power applications. Cooling System: Over-coil cooling system allows air exchange over the voice coil through the spider.
External Component Crossover: External Passive Butterworth crossover for a smooth transition of frequencies from midrange/midbass to the tweeter element designed....

Special dual-resonance design One coil acts as woofer and other as a tweeter Extended range of noise-canceling Less magnetic pull Clean, clear, bright sound Output: 140mV.
But if you're the player who's up for something more modern with no 60-cycle hum, string drop-outs or sustain-killing magnet pull, The Cruiseros designed for you.
Harmonic overtones are right where you expect them to be from a "true" single-coil, and the mid-range is open and vocal-sounding.
No humbucking pickup sounds exactly like a vintage single-coil, but the Cruiser is about as close as it gets.
The special dual-resonance design allows one coil to act as a woofer and the other as a tweeter.
