At USD 66, this is a strong bargain against the comparable market: it sits below the USD 74 25th percentile and well under the USD 117 median. Even allowing for the untested status, the price leaves useful room for a repair—or makes it worthwhile as a low-cost project if the seller includes the correct power supply.
The DTA-2.1BT2 is a genuinely handy little system amp, delivering 50 watts per channel plus a dedicated 100-watt passive-subwoofer output, with Bluetooth, RCA, and 3.5mm inputs. It is well suited to a desktop, office, or compact bookshelf setup, and the adjustable sub crossover adds real flexibility. Because it is untested, confirm that the 24V power supply is present and inspect for damage; if it powers up and passes audio, USD 66 is excellent value.

Dayton Audio emerged over three decades ago as a specialist in audio components, with roots firmly in the United States where most engineering and development occurs. While specific founding details remain unverified, the brand has built its heritage on loudspeaker design and production, manufacturing goods across North America, Europe, and Asia to balance quality and accessibility. This American-led approach has positioned it as a reliable source for practical hi-fi solutions since at least the early 1990s.
The company focuses primarily on loudspeaker drivers and related components, offering transducers in sizes from 3 to 12 inches that rival premium models in performance. Its Designer Series emphasizes full power handling at low frequencies without exceeding excursion limits, ideal for custom enclosures. Dayton also produces plate amplifiers suited to bespoke builds, catering to DIY enthusiasts and manufacturers seeking high-value drivers over complete systems like amplifiers, turntables, or headphones.
Dayton Audio holds a strong mid-tier position in the market, delivering engaging sound and robust quality akin to high-end brands but at budget prices. Esteemed by hobbyists and builders for competing with the world's finest drivers, it thrives in the value-driven segment, appealing to knowledgeable buyers prioritizing performance per dollar over luxury branding.
