*Dear Valued Customers*

We would like to inform you that due in part to the passing of both Phil and Daniel,

We are currently looking to sell the whole lot or large sections of our inventory.
If you or anyone you know (including businesses) are interested,
please email us at:

Once our inventory has found a new home,
we will gladly provide an update below as to where it has moved.

We sincerely thank you for your understanding and continued support since 1971!

and "Foam Surrounds" have now moved to Innovative Audio!
