The M-Audio BX4 is the third entry in this guide, and it is a pair of powered desktop monitors rather than a single box: two 4.5-inch Kevlar woofers, two 2.54 cm silk dome tweeters, bi-amplified per the bullet points, in MDF cabinets with a bass reflex port. The listing's Unit Count reads 2.0 count and the price is £99.99, so that figure covers both speakers. The comparison worth making on this page is the one the guide makes: the M-Audio BX5 in the same round-up is listed at £92.00 for one 5-inch monitor, which is £184.00 for a stereo pair, against £99.99 here for two cabinets.

The spec table is worth reading field by field, because not all of it describes a wired desktop monitor. Controller Type says Remote Control, while Control Method on the same listing says Push Button, and none of the six bullet points mentions a remote. Maximum Range is given as 2 metres. Subwoofer Speaker Diameter is 11.5 cm on a product with no subwoofer in it — that number does line up with the 4.5-inch woofer, but the label does not. The 120W figure appears once, in the Product Features field, with no split between the two drivers. Everything below is taken from the Amazon listing as it stands, not from any testing of our own.

## Questions people ask

**Does £99.99 buy one M-Audio BX4 or two?**

Two. The title says 'Pair' and the Unit Count field reads 2.0 count, so the £99.99 covers both speakers.

**What size are the drivers on the M-Audio BX4?**

The listing specifies 4.5-inch Kevlar woofers, recorded as 11.5 cm, paired with 2.54 cm natural silk dome tweeters.

**How much power do they have?**

The only power figure anywhere in the listing is 120W, and it appears in the Product Features field. The bullet points say the amplification is bi-amplified, but they do not split the wattage between woofer and tweeter, or between the two cabinets.

**Is there a remote control in the box?**

The listing contradicts itself here. Controller Type reads Remote Control, Control Method reads Push Button, and no remote is mentioned in any of the six bullet points.

**What inputs does the M-Audio BX4 offer?**

The Product Features field lists Aux in and Headphone Out, and the bullets describe a wired, zero-latency connection for streaming, gaming and studio work. The Maximum Range field reads 2 metres, and no wireless connection is claimed in the bullet points.

**What does the listing say about warranty and spare parts?**

Warranty Type is 'Limited' with no length stated, and EU Spare Part Availability Duration is given as 7 years.
