At US$73, this looks fair-to-good rather than a bargain: used BA735 sets show up around US$45 on eBay and US$10 on Reverb, with some higher local asks around US$100. For a clean, complete, fully working set, US$73 sits in the sensible middle of that spread, though it isn’t the kind of sub-US$50 steal that would make me jump immediately.
The BA735 is a well-liked compact 2.1 PC speaker system from Boston Acoustics, and the appeal is straightforward: small footprint, easy desktop use, and a reputation for solid sound for the size. At this price, the real value is in condition and completeness—make sure the powered unit, satellites, and original cabling are all present and working, since those older multimedia systems are only a good buy when they’re ready to plug in and play.

Boston Acoustics emerged in 1979 from the innovative spirit of America's Northeast audio scene, founded by Advent veterans Andy Kotsatos and Frank Reed in Lynnfield, Massachusetts. Drawing on their experience at pioneering firms like KLH and Advent, the duo established the company to craft high-quality loudspeakers that balanced engineering precision with musical fidelity. Their early flagship, the A70, quickly earned acclaim in the 1980s for its exceptional sound, setting a foundation rooted in MIT-level expertise and a commitment to superior design at accessible prices.
The brand focused primarily on speakers across diverse categories, including home bookshelf and floorstanding models, custom architectural installations, and robust car audio systems. They expanded into surround sound solutions for home theater and even ventured into compact computer speakers and outdoor options like the SoundWare series, while maintaining a core emphasis on transducers rather than amplifiers, turntables, or headphones.
Positioned as a mid-tier powerhouse, Boston Acoustics built a sterling reputation for value-driven performance that punched above its price, appealing to discerning audiophiles through dealer networks and later direct sales. Acquired by D&M Holdings in 2005 and integrated into Sound United by 2017, the brand's legacy endures among vintage collectors for its engineering excellence, though active production has ceased.
