Stop Mixing on Low-quality Multimedia Speakers

Get to know them!

Mixing on subpar studio monitors is an exercise in futility that will only lead to frustration. So, do your mixes a huge favor by upgrading to a pair of M-Audio BX4 monitors. Each of these compact studio monitors deploys a 4.5-inch Kevlar woofer and a 1-inch silk dome tweeter to deliver the clarity and detail you need to make proper mix decisions. A computer-optimized waveguide ensures precise imaging; an enhanced rear-mounted port works in concert with each speaker’s acoustically inert MDF cabinet and bass reflex design to yield low-end extension down to 69Hz. And if you need to further dial in your sounds, each BX4 includes a High- and Low-EQ control.

Built to deliver critical detail, nuance, and dynamic accuracy

Each BX4 was meticulously engineered to provide accurate sound reproduction. It all starts with a high-quality 4.5-inch Kevlar woofer and 1-inch natural silk dome tweeter, which ably cover the 69Hz–22kHz frequency range. Imaging is spot-on, thanks to a computer-optimized tweeter waveguide, while an enhanced rear port delivers extended low-frequency response. An acoustically inert MDF cabinet with a bass reflex design also contributes to the deep, rich sound of these studio monitors. You also get High- and Low-EQ controls for dialing in your sound.

Jam-packed with convenient features

Each M-Audio BX4 is jam-packed with convenient features. A Left/Right Active Speaker Position switch enables you to configure which side has a volume control. The 1/4-inch, 1/8-inch, and RCA inputs accommodate just about any audio source — you even get an 1/8-inch to 1/8-inch cable and an 1/8-inch to RCA cable in the box! This set of BX4 studio monitors includes a software suite with Pro Tools | First M-Audio Edition and 20 Avid effect plug-ins, so you can start making music right away.

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. 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.
