Cabinet type and stated extension, not the number on the amplifier · review
The best-specified subwoofer in this catalog: it publishes a frequency extension figure — 35 Hz — which nothing else here does.
In brief
The subwoofer that publishes what matters: an extension figure, a cabinet material and a filter — modest in size, and the only one here that can be compared on the right number. Key figures: 8-inch driver · 70 W · low-pass filter · down to 35 Hz stated · MDF cabinet · RCA · standby. Amazon.com had a product page for it but no seller on October 25, 2026. Our score: 7.7/10, specification-checked.
Down to 35 Hz. It is the figure that says how low a subwoofer reaches, and it is absent from every other subwoofer listing in this catalog. What would make it fully rigorous is a tolerance — “35 Hz (−6 dB)” — and that is not stated. As published, it is still more than anything else here offers.
MDF, described as reducing resonance. A subwoofer cabinet that vibrates adds its own sound to the music, and material is one of the two things that stop it. It is a modest specification and it is a specification.
On board, which means the subwoofer can be integrated even with an amplifier that offers no crossover control. On a two-channel system, that is the difference between a subwoofer that blends and one that booms.
Fill a large room. An 8-inch driver on 70 W is a small-to-medium-room proposition, and the honest comparison is against the 12-inch cabinet elsewhere in this catalog rather than alongside it.
Automatic. A subwoofer is left powered permanently, and a component that sleeps when nothing is playing is one less thing consuming electricity for years.

Because it is the specification that actually says how low a subwoofer goes, and almost nobody publishes it. Driver size and power are proxies; extension is the answer. Here it is stated as 35 Hz, though without the tolerance that would make it fully rigorous.
It sets the frequency above which the subwoofer stops playing, so it does not overlap with the main speakers. If the amplifier or receiver has no crossover control, the filter on the subwoofer is what makes integration possible at all.
7.7/ 10
The subwoofer that publishes what matters: an extension figure, a cabinet material and a filter — modest in size, and the only one here that can be compared on the right number.
A small to medium room, and anyone who wants to compare a published number rather than infer from a driver size.

12 in (30.5 cm) front-firing driver · all-digital amplifier · 400 W dynamic power · 29–120 Hz stated
A 12 in front-firing subwoofer with an all-digital amplifier rated at 400 W of dynamic power and a stated 29–120 Hz response — the largest driver on this shelf.
Best for: A living room where the subwoofer has to keep up with films — and a receiver with an LFE output to feed it.

Active · 60/120 W stated as a pair · sold singly
A German-made active subwoofer quoted conservatively — 60/120 W — in the two-figure form that makes a rating comparable rather than impressive.
Best for: A small or medium room, and a system built from components rather than bought as a package.

Active · 150 W · front-firing or downfiring · sealed or ported not stated
A subwoofer that can be oriented front-firing or downfiring — a placement flexibility that matters more in a real room than a specification does.
Best for: A room where the subwoofer has to go under or beside furniture, and orientation decides whether it works there.
