BOZAK COMPANY.  B-4000 Grandeur of Music stereo speaker, also known as Symphony No. 1, for those who seek big, full sound but whose space does not permit the celebrated B-310A  Concert Grand.  No truer re-creation of live sound has ever been achieved.  The proof is in the hearing.

This unique old one page 1962 high fidelity stereo component trade magazine advertisement would display beautifully matted and framed.  It would make a nice accompaniment to your vintage stereo.
