What they actually do
Compact speakers for surround positions, and the cables and connectors a system needs once the boxes are chosen.
Where the money matters
On cable, cross-section against length is the whole specification, and the returns stop early.
The AS-301, and what one driver means
The AS-301 is the only Dynavox speaker reviewed here. Its listing states a passive satellite pair with a single full-range driver, an “ultra compact” cabinet, wall mounting, and use as surround speakers in a 5.1 system or in an office. One driver covering the whole band means there is no crossover inside the cabinet to get wrong, and also no tweeter to carry the top octave: that is the trade at the heart of the smallest surround speakers.
The listing publishes no power handling, no impedance and no sensitivity, so there is no figure to match against a receiver. Read the review before assuming it suits yours.
Buying Dynavox in the United States
We hold European Amazon references for the AS-301 only, and Amazon.com had no offer for it on October 25, 2026. On the surround speakers shelf, the models with a US offer that day included the Pyle PLMR24B at $30, two Rockville pairs at $60 and $65, and the Polk Audio at $249.
