Impedance and Extension Cabinets

By Sweetwater on October 6, 2009

When using an extension speaker with an amplifier, be sure to double-check that the amp is seeing the proper impedance. If a single extension cabinet is being used, and the amp does not contain a speaker of its own, then ensure that the cab has the right impedance to match the head. If more than one extension cabinet is being used, or, if an extension cabinet is being used with a combo amp that contains a speaker of its own, then ensure that the total impedance seen by the amp (the total impedance of all the connected speakers) is correct.

Offer applies only to single-receipt qualifying purchases. No interest will be charged on the promo balance if you pay it off, in full, within the promo period. If you do not, interest will be charged on the promo balance from the purchase date. The required minimum monthly payments may or may not pay off the promo balance before the end of the promo period, depending on purchase amount, promo length and payment allocation. Regular account terms apply to non-promo purchases and, after promo period ends, to the promo balance. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
