Introduction

Thank you for choosing the Studiophile Series BX5a Deluxe bi-amplified studio near-field monitor

speakers. M-Audio is well known for digital audio interface technology, digital converters, audio

preamps and mixers. Now, after extensive research and development, M-Audio is proud to present the

Studiophile BX5a Deluxe.

The BX5a Deluxe was designed and tested by veteran audio engineers to meet your needs in a studio

monitoring environment. It is focused on the functional goal of delivering pure, original sound without

any additional coloration. The BX5a Deluxe monitor is self-powered, directly accepting a line-level

signal from a variety of sources.

The Studiophile BX5a Deluxe is designed to overcome all the limitations of conventional studio

reference monitors within the digital audio environment. This system delivers a wide-range frequency

response by employing two extraordinary drivers and unique crossover technology licensed by

M-Audio. It boasts a stable and balanced low-mid frequency response along with a defined mid and

high-frequency response as well. Both drivers are magnetically shielded for desktop music production.

For pro engineers at commercial studios to home studio owners, the Studiophile BX5a Deluxe sets a

new affordable standard in studio monitoring.

Studiophile BX5a Deluxe Features

1. Woofer

The woofer unit is 5 inches in diameter with a magnetically shielded Kevlar cone, high-temperature

voice coil and damped rubber surround. It is designed to deliver balanced mid and low-frequency

response. M-Audio’s new BX5a Deluxe employs Kevlar for low-frequency driver construction. The

same material used in bullet-proof vests, Kevlar’s high resilience makes it ideal for use in speaker

cones—although it is typically reserved for monitors with higher price tags than the BX5a Deluxe.

Needless to say, Kevlar represents a significant improvement over the polypropylene and paper used

in most monitors at this price.

2. Tweeter

By employing a specially developed 1-inch silk dome with magnetic shielding, the tweeter can deliver

distortion-free original sound and offer an extremely natural response. Its design minimizes reaction

time by using a specially shaped silk dome for excellent delivery, and also minimizes resonance by

adapting a unique internal damping technology.

3. Sub-Frequency Port

The air vent hole in the rear panel is called a Sub-Frequency Vent Port and is designed to allow the

discharge of extremely low frequencies occurring below 60Hz.

4. Enclosure

Like the other components, the BX5a’s enclosure has an important role in shaping the overall sonic

response. In order to provide more stable performance, the BX5a’s enclosure employs a special high

acoustic efficiency MDF and unique interior reinforcement designed to absorb vibration and impact

generated under extreme conditions. The custom design on the front panel will aid in diffraction and

will benefit stereo imaging.

5. Network and Power Amplifiers

The active crossover network and power amplifiers for the BX5a Deluxe are specially designed for

its woofer and tweeter. The network properly distributes low, mid, and high frequencies to the driver

components in order to reduce distortion and loss of sound, thus achieving a naturally balanced

sound.

In order to generate powerful, ultra-crisp sound, there are two separate power amplifiers inside the

BX5a Deluxe for driving the woofer and tweeter separately in a high-end bi-amp structure. The power

delivered to the woofer driver at a low-rated distortion is 40W, and 30W is also delivered to the

tweeter.
