Frequently Asked Questions

What payment methods do you accept?

You can pay with any major credit card (Visa, Mastercard, American Express, Discover) or PayPal. We don't take checks, money orders or cash except for in person purchases.

Can I place an order over the phone?

Yes, just give us a call on 415 524 8741 and we'll process your order over the phone. Please note that not all of our products can be purchased over the phone. In general if you can buy a product online then you can buy it over the phone.

How do you calculate shipping?

We use UPS and USPS for shipping. Most items are shipped UPS ground, since this is the best option for heavy and bulky items of acoustical treatment. Shipping costs are based on size, weight and destination.

How fast do you ship?

Shipping time varies by stock status.

  • In stock products ship within 1 or 2 business days.
  • Most other products ship within 7-10 business days.
  • RPGs made to order acoustic treatment ships within 6-10 weeks.

What are RPGs minimum order requirements?

RPG does not accept single panel orders. Any combination of 2+ panels from their product lineup such as two FlatFussors or one FlatFussor and one Absorber meets their requirements.

When is my payment processed?

Your payment is procesed immediately. Many of our items are made to order and therefore we process on order receipt, not on order ship.

Do you ship internationally?

  • Everything except acoustic treatment - yes!
  • Acoustic treatment - we do not ship acoustic treatment products outside of the US and Canada due to their size and bulk. If you try and checkout with these products in your cart and you have an shipping address not in the US or Canada then you will get an error message. If you really want a product then you are welcome to use a freight forwarder based in the US or Canada. We will send the product to them, and they will send it to you.
  • Any brokerage and customs charges are the responsibility of the recipient, not Acoustic Frontiers

Why am I being charged sales tax?
