BETTER SOUND THAN FACTORY

Factory speakers are often built around cost and weight rather than sound quality.

The HELIX CB K165.2-S3 gives you improved:

Vocal clarity

Midbass impact

Treble detail

Soundstage

Overall listening quality

The 3 Ohm design also helps compatible amplifiers deliver more useful power to the speakers.

🟡 A GREAT FIRST STEP INTO PROPER CAR AUDIO

6.5 INCH MIDBASS

The 165 mm midbass driver uses a lightweight polypropylene cone designed to combine good stiffness with low moving mass.

This helps produce controlled midbass while maintaining clear reproduction through the vocal range.

The steel basket includes additional ventilation to improve voice coil cooling and power handling.

SILK DOME TWEETER

The included 20 mm silk dome tweeter provides smooth and detailed high frequency reproduction.

A neodymium magnet allows the tweeter to remain compact while still delivering strong performance.

This makes the tweeter easier to integrate into factory locations where space can be limited.

FLEXMOUNT20 COMPATIBLE

The tweeters are compatible with the HELIX FlexMount20 system.

With the correct optional adaptor, the universal tweeter can be installed into many original factory mounting locations for a cleaner and more professional installation.

🟡 UNIVERSAL SPEAKER PERFORMANCE WITH VEHICLE SPECIFIC INSTALLATION OPTIONS

DEDICATED CROSSOVERS

The included crossovers are designed specifically for the midbass and tweeter combination.

They feature:

12 dB tweeter high pass filtering

4 stage tweeter level adjustment

Integrated tweeter protection

This gives the installer additional control over the amount of treble depending on the tweeter position and vehicle acoustics.
