The speakers and enclosures formely branded as QSI Solutions have been re-branded to TDS. The actual products are the exact same speakers and enclosures. So many of you may be asking why the name was changed.

It's simple really.

These have always been distributed by American Hobby Distributors (AHD) and were originally given the brand name "TDS".
When AHD purchased QSI Solutions, which makes sound decoders, it was natural for AHD to change their branding to "QSI".
AHD later sold QSI Solutions, so the speakers were re-branded back to the original "TDS".

Until all previous inventory is depleted, some speakers and some enclosures may still be in the previous QSI Solutions packaging.
