Sigma Fabrications MB4 — buyer FAQs
What is the Sigma Fabrications MB4 and what is it used for?
The Sigma Fabrications MB4 is a 15-inch wedge stage monitor designed for live performance use. It is used by musicians and sound engineers who need reliable on-stage audio monitoring, and suits both solo performers and bands. Its wedge form factor is intended to sit on stage flooring and project sound toward the performer, helping them hear their own mix clearly during a live show.
Who makes the MB4 monitor and where does it fit in the market?
The MB4 is made by Sigma Fabrications, also referenced in the market under the SSE brand name. The monitor sits in the professional live sound sector, aimed at musicians and sound engineers working in stage environments. It is a 15-inch wedge model focused on consistent audio fidelity and robust construction for demanding live performance conditions.
What amplification is the Sigma Fabrications MB4 typically used with?
The MB4 is a passive wedge monitor and requires external amplification. Used packages sometimes include Camco Vortex 4 amplifiers fitted with UCA cards alongside the MB4 monitors. If buying a single monitor rather than a complete package, amplifier compatibility should be confirmed separately before purchase.
What should I check when buying a used Sigma Fabrications MB4?
When buying a second-hand MB4, inspect the 15-inch driver for damage, check the cabinet for structural integrity, and confirm whether the unit is sold individually or as part of a multi-monitor package with amplification. Used listings vary in configuration and condition. Every listing on 10K Used carries a 21-day warranty covering major functional faults; full details are in the buying guide at 10kused.com/used-av-equipment-guide/.
How much does a used Sigma Fabrications MB4 cost?
The used price of an MB4 varies depending on condition, whether the unit is sold individually or as part of a package that includes amplifiers, and overall age. A complete package with multiple monitors and amplifiers will naturally carry a higher price than a single monitor sold alone.
