Twelve-speaker passive set for distributed audio

The Theater Solutions TS30B ships as twelve identical passive speakers designed for whole-house or multi-zone installations. Each unit uses a traditional passive topology that draws power from an external amplifier or receiver. Spring-loaded raw-wire terminals accept standard speaker cable for quick connection. The package includes mounting brackets and hardware for wall or ceiling placement.

Steady output across long listening sessions

With a rated impedance of 8 ohms and a sensitivity of 89 dB, the speakers maintain consistent output when driven by an amplifier delivering between 20 and 200 watts per channel. The 2.5-inch poly-treated cone woofers cover a frequency range of 140 Hz to 20 kHz without compression during extended playback. Sealed ABS cabinets prevent port resonance that can color sustained mid-bass material.

Low thermal load and silent operation

Passive construction means the speakers generate no heat of their own and add no fan noise to the room. Power dissipation occurs entirely in the connected amplifier, keeping the listening area thermally neutral. Compact sealed enclosures measuring 3.5 by 3.375 by 4.25 inches allow discreet placement without obstructing airflow around other equipment.

Questions about this item

How much heat or noise do these TS30B speakers add when running all day?

As passive speakers with no built-in amplifier or moving parts beyond the 2.5" drivers, they produce no fan noise and negligible heat; all power dissipation occurs in your external amplifier.

What must I already own to make this 12-pack work?

You need an amplifier or receiver with raw speaker-wire outputs capable of 20–200 watts per channel into 8 ohms, plus CL3 or raw speaker cable for each run.

Will these 89 dB, 140 Hz–20 kHz speakers integrate with my older amp and existing subwoofer?

Yes — the 8 ohm nominal impedance and 89 dB sensitivity suit most legacy amps, while the 140 Hz low-end lets a separate sub handle bass below that point.
