Sedona SN28 Teardown: 5-Speaker Surround & Subwoofer Hardware

Deconstructing reference-grade 5-speaker surround systems requires evaluating physical enclosure acoustics, crossover phase alignment, and dedicated low-frequency subwoofer amplifier reserves. The flagship Sedona SN28 5-Speaker Home Theater System represents Sedona Hi-Fi's most uncompromising surround solution.

In this technical hardware teardown, we dismantle the Sedona SN28 System to inspect its dual-cube satellite driver modules, active subwoofer power stage, high-precision center channel assembly, and $3,158.99 MSRP component craftsmanship.

Subwoofer Tower Architecture & Active Low-Frequency Driver

Opening the main subwoofer cabinet of the Sedona SN28 reveals a high-excursion low-frequency woofer mounted inside a heavy MDF enclosure. The driver features double-stacked ferrite magnets, a high-rigidity cone, and a tuned lower front bass port for turbulent-free low-frequency extension.

The internal amplification block is a high-efficiency Class-D power stage mounted to a thick aluminum heatsink plate. High-capacity power supply capacitors ensure massive dynamic headroom during sudden movie sound effects and deep musical basslines.

Key Technical Specifications

Here is the hardware specification summary for the Sedona SN28 5-Speaker Theater System:

• Acoustic System Topology: Uncompromising 5-Speaker Surround System (4 Dual-Cube Satellites + 1 Center Channel + Active Subwoofer)
• Satellite Driver Configuration: Direct/Reflecting Dual-Cube Neodymium Transducer Modules
• Center Channel Transducer: Dual Mid-Range Drivers with High-Fidelity Voice Voice Isolation
• Active Subwoofer Unit: High-Excursion Driver in Symmetrical MDF Cabinet with Front Bass Port
• Signal Decoding & Crossover: Active Digital Signal Processor (DSP) with Multi-Channel Phase Correction
• Enclosure Finish: Matte Black High-Density Polycarbonate & Acoustic Mesh Grilles
• Standby Power Consumption: < 0.5W Eco Mode Standby
• MSRP / Retail Price: $3,158.99 USD

Dual-Cube Satellite Modules & Phase Alignment PCB

Examining the individual dual-cube satellite speakers reveals a clever acoustic swivel mechanism. Each cube houses custom neodymium drivers that can be angled independently to balance direct and reflected sound in the listening room.

Inside the main control unit, the crossover PCB utilizes high-purity copper traces and audio-grade polypropylene film capacitors. The crossover network seamlessly transitions frequencies between the dual-cube satellites and the active subwoofer without phase cancellation.

Enclosure Dampening & Thermal Dissipation

To eliminate cabinet coloration, Sedona Hi-Fi reinforces all satellite and center enclosures with internal acoustic baffles and synthetic dampening fiber.

• Vibration-Isolated Feet: Prevents cabinet resonance from transferring into wooden furniture surfaces.
• Passive Convection Cooling: Aluminum amplifier heatsink ensures silent zero-fan operation.
• Universal Source Compatibility: Connects to A/V receivers, Smart TVs, and high-resolution digital sources.

Teardown Pros & Cons

Hardware Strengths (Pros)

• Uncompromising 5-Speaker Surround Engineering: Enormous spatial soundstage with pinpoint channel separation.
• Dual-Cube Swivel Satellites: Custom directional tuning for optimal room acoustic reflections.
• High-Excursion Active Subwoofer: Delivers deep, visceral sub-bass down to sub-audible frequencies.
• Premium Craftsmanship & Materials: Robust MDF and high-density polycarbonate enclosure build.

Engineering Trade-offs (Cons)

• Dedicated Subwoofer Footprint: Subwoofer tower requires dedicated floor space near room boundaries.
• Wired Satellite Runs: Requires discrete speaker wire routing from the central control module.

Teardown Verdict: Outstanding 5-Speaker Theater Surround

The Sedona SN28 5-Speaker Home Theater System is an acoustic triumph, pairing dual-cube swivel satellites, an active subwoofer tower, and precision DSP crossover design for an MSRP of $3,158.99 USD.
