What Is Bose 901 Series III Speaker Worth?

The typical price range for Bose 901 Series III Speaker is $300 - $500 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Physical condition of the wood veneer and the integrity of the iconic wrap-around grille cloths.
• The functional state of the foam surrounds, as original Series III drivers are prone to 'foam rot' over time.
• Inclusion of the original tulip pedestals or matching floor stands which significantly increase market desirability.
• Presence and working condition of the dedicated Series III Active Equalizer, which is essential for proper frequency response.

How to Identify Bose 901 Series III Speaker?

• Verify the 'Series III' designation on the rear terminal plate or the distinctive wood-grain cabinet finish.
• Check for the presence of the required external Active Equalizer, which is specific to the Series III circuitry.
• Inspect the nine internal drivers to ensure they feature the correct foam surrounds used during the 1978-1983 production era.
• Confirm the 'Made in USA' origin marking typically found on the back of the enclosure.
