All three models - including a subwoofer - are designed to resemble small modern halogen type enclosures, providing "the most discrete sound installation speakers yet devised, while employing proprietary Boston Acoustics' technology and engineering to ensure that this is achieved without any compromise to the company's renowned sound quality".
The HSi 430 and HSi 435 are 3½ " hi/mid enclosures, with round and square bezels respectively; the matching HSi S6W2 subwoofer also comes with alternative bezel forms. In addition to their diminutive size, the speakers feature dramatically reduced bezel visibility - making installations virtually invisible - and magnetically fixed grilles for simple installation.
