The Unity speaker line offers an ideal solution to upgrade the speaker system in a vehicle having factory dash speaker locations by including two wide-bandwidth speaker options. The 3.7-inch Unity U3, featured here, is a high-performance driver designed to function as the in-dash speaker in a 2-way or 3-way front stage, in conjunction with the various Unity midbass drivers, and optionally with the Unity U1 tweeter.
Also available are the U2x-W and U2x passive crossovers, offering flexible options to create the ideal 2-way or 3-way front stage solution when passive crossovers are necessary. The Unity U69-S is a shallow-mount option to the Unity U69V2 6×9-inch driver, and with a mounting depth of just 75mm is the shallowest high-performance 6×9-inch woofer of its kind.

Cast ABS plastic. The basket is a high-quality cast ABS design, which plays a critical role in aligning the voice coil in the magnetic circuit. Additionally, the cast ABS frame allows for better clamping strength versus stamped steel frames and ensures that the voice coil remains centered in the former. The midrange frames (Unity U2 and U3) are a proprietarily-tooled design owned by Hybrid Audio Technologies, having no OEM industry equivalent, and share standard mounting hole diameter and similar mounting depths to the Legatia and Legatia SE midranges for potential/future upgrade potential. The midbass frame (Unity U5, Unity U6, and Unity U69) is a shared technology with the Imagine Powersports-series coaxial sets allowing for immediate upgrade potential due to having the same size footprint, mounting depth, bolt circle diameter, and motor diameter as the Imagine systems.
Cone and Dust Cap
Pressed paper with waterproof treatment. It is widely acknowledged that pressed paper cones are the best marriage of lightness, stiffness, and the ability of the cone to damp unwanted cone and edge modes and resonances (read: distortion). The paper cone, known for its excellent sonic attributes, is waterproof, thanks to a polymer developed exclusive and proprietarily by Hybrid Audio Technologies. The treatment does not change the look and parameters of the driver like old-fashioned “glossy” polymers which added an appreciable amount of moving mass and significantly colored the sound. No, the Unity cones look like any “normal” paper cone, but in reality, are likely the only high-performance waterproof paper cone car audio speaker systems on the market. The treatment protects the cone from periodic drips (such as inside a door panel), as well as accidental splashes to the front of the cone. Likewise, the paper dust cap is also treated for water resistance. The cone is a shared technology with the Imagine series coaxial sets. Check out this video of an actual water-proof demonstration, where we pour two liters of water over the driver and then connect it to a musical source.
Inverted high-loss rubber surround. The inverted high-loss rubber surround (in concert with the spider, detailed below), helps to provide the compliance and “restorative force” needed for the Unity drivers to play effectively into the lower midbass, and even upper subbass frequencies (depending on in-car cabin gain and other factors). You’ll also know a Hybrid Audio midrange and midbass design by its inverted surround; this design feature allows for the use of a smaller height grille, better clearance with OEM panels, and more flexibility in mounting options. The surround is a shared technology with the Imagine series coaxial and convertible component sets.
Phenolic fabric and tinned tinsel leads. The spider is the brownish/yellow corrugated (rippled) fabric that attaches the cone and voice coil. The spider for the Unity designs was the subject of a considerable amount of our research and development. The spider is a phenolic symmetrically-rolled fabric which provides excellent restorative force during excursion. The spider is vented courteous of the speaker frame; a design element not typically found in this price range of speaker system. The spider venting increases the thermal power handling of the Unity midbass driver. The tinsel leads are connected to real epoxy PCB, not flimsy cardboard. The spider, tinsel leads, and terminals are shared technologies with the Imagine series coaxial sets.
Voice Coil and Motor System
The voice coil used in the Unity midbass is a 2-layer aluminized copper wire coils on a round former. An “overhung” voice coil was selected to improve sensitivity while still keeping distortion to a minimum. The voice coil and motor system are shared technologies with the Imagine series coaxial sets.
