{"product_id":"syz-slf820-821260","title":"Syzygy SLF-820 — 8\" Powered Wireless Subwoofer","description":"\u003cp class=\"p1\"\u003eSyzygy builds the SLF-820 around an acoustic suspension design rather than a ported enclosure, and the choice matters. A sealed cabinet uses a cushion of trapped air to regulate cone travel precisely — less overshoot, tighter transient response, and bass that stops when the signal stops rather than hanging in the room a half-beat too long. The tradeoff is typically extension, but the SLF-820's 400-watt amplifier driving a proprietary woven cellulose fiber diaphragm gets it to genuine 30Hz in an 11-inch cube. 100dB output from something that size is not a given — it reflects the amplifier-to-driver match Syzygy built around the sealed alignment rather than relying on port tuning to make up for an underpowered amp. The wireless transmitter is included and supports linking multiple SLF-820s to a single source — useful for distributed bass in a larger room or a dual-sub setup without running cables across the floor. Front- or down-firing orientation. Auto standby. RCA line-level input for wired connection when preferred. The SLF-820 is the subwoofer for the room where cable management is the deciding factor and you still want real bass on the other end of the connection.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eWe have two available.
