About the Infinity Kappa Perfect 5.1
Sonic sizzle from Infinity! The Kappa Series Perfect 5.1 5-1/4" component speaker system delivers stunning detail and pinpoint accuracy from deep-anodized-aluminum woofers and tweeters that hold their shape regardless of power level, ensuring superior clarity of output for years.
Each 1" tweeter features an edge-driven, anodized-aluminum dome suspended by a butyl rubber surround. A powerful neodymium magnet drives the tweeter for clean, shimmering highs. Infinity's patented I-Mount tweeter-mounting system allows for easy flush, angled, or surface mounting.
A precision outboard crossover is used to divide frequencies seamlessly between the woofer and tweeter (24 dB/octave high-pass/low-pass at 3,500 Hz). You can adjust the tweeter output level to maximize system performance and imaging based on location.
The Perfect 5.1 system can handle plenty of raw power (up to 100 watts RMS), making it a great choice for the enthusiast looking for a system that will sound every bit as good at high output levels as at moderate ones.

Woofers: The deep-anodized-aluminum woofer cones ensure incredible detail and accuracy. This material holds its shape regardless of output level, unlike more commonly used materials.
Surrounds: The butyl rubber surrounds have greater internal loss than standard urethane, preventing harmonic distortion at higher frequencies. The butyl rubber more efficiently absorbs edge reflections that can cause audible distortion, resulting in clearer bass performance.
Tweeters: Each 1" tweeter features an anodized-aluminum dome suspended by a rubber surround. The tweeters are driven by a powerful neodymium magnet, resulting in higher power handling and superior detail. The rubber surround helps reduce the resonant frequency of the tweeter, giving you cleaner, more accurate sound reproduction.
"I-Mount" Tweeter Mounting System: Surface mounting involves mounting the surface mount cup (using the supplied screws), then snapping the tweeter into the cup. Flush mounting is made easy through the use of the threaded flush mount adapter and plastic locking nut. For flush mounting, the tweeter is snapped into the flush mount cup. Then, the cup is secured to the flush mount adapter with a nut and clip washer. Once a cutout is made, the flush mount adapter (with the tweeter installed) is inserted into the hole. The large plastic locking nut is threaded onto the adapter (from behind the mounting surface) to hold the complete assembly securely in place. When flush mounted, the tweeters may be angled for optimum response and imaging. There are no provisions for angled surface mounting of the tweeters.
Tweeter Mounting Dimensions:
|Surface Mount||Flush Mount|
(0.334" screw depth)
2-Way Crossovers: Each crossover features a 24dB/octave, 3.5kHz high-pass network for the tweeter and a 24dB/octave, 3.5kHz low-pass network for the woofer.
Selectable Tweeter Output Level: Each crossover has 3 adjustments that allow you to select the tweeter output level according to system requirements and personal preference. The adjustments may be set to "-4dB", "5dB" or "0dB".
Crossover Connections: The crossover inputs and outputs are gold-plated screw terminals.
Mounting: There are four mounting holes in the base of each crossover.
