Mesa/Boogie Split Back Cabs: A Review of a Legend Reborn

Mesa/Boogie has recently re-introduced their iconic Split Back series of guitar cabinets, much to the delight of players who remember their impact on the sound of 1980s rock and beyond. These innovative cabinets, available in both 2×12 and 4×12 configurations, offer a unique design that blends the sonic characteristics of both open-back and closed-back cabinets into a single unit. This review will delve into the features and sonic performance of the Mesa/Boogie Split Back cabs.

Features and Design

The core innovation of the Split Back cab lies in its divided back panel. The top portion of the cabinet features an open back design, while the bottom section is closed and, in the case of the 2×12, ported. This configuration aims to provide the airy, articulate high-end response associated with open-back cabs and the tight, punchy low-end typically found in closed-back designs.

Construction: Mesa/Boogie is renowned for its high-quality construction, and the Split Back cabs are no exception. They are built using void-free marine-grade Baltic birch plywood, ensuring durability and optimal tonal resonance. The cabinets are covered in tough Bronco Tolex vinyl and feature hand-formed leather corners for added protection. A sturdy expanded metal grille protects the speakers while adding a touch of classic Mesa/Boogie aesthetics.

Speakers: The speaker configurations differ between the 2×12 and 4×12 models:

• 2×12 Split Back: This model houses two Celestion C90 speakers. The top speaker resides in the open-back chamber, contributing to the open and clear high frequencies. The bottom speaker is placed in a sealed and ported chamber, enhancing the low-end response with added punch and girth. The 2×12 cab has a power handling of 180 watts and an impedance of 8 ohms, with a parallel output jack for connecting an additional 8-ohm cabinet.
• 4×12 Split Back: The larger 4×12 cabinet features two Celestion C90 speakers in the open-back top section and two Celestion Vintage 30 speakers in the sealed lower section. This combination aims to deliver a broad tonal palette, with the C90s providing clarity and the Vintage 30s contributing their characteristic midrange scoop and powerful low-end. The 4×12 has a power handling of 300 watts and can operate in mono (8 ohms) or stereo (4 ohms per side) via separate inputs.

Portability: Despite their robust construction and powerful sound, Mesa/Boogie has considered portability. Both the 2×12 and 4×12 Split Back cabs come equipped with removable Track-Loc casters, making transportation and setup significantly easier.

Sonic Performance

The Split Back design truly delivers a versatile sonic experience. Players can expect:

• Clear and Airy Highs: The open-back portion of the cabinet provides a spacious and articulate top-end, ideal for clean tones, chimey chords, and nuanced lead work.
• Tight and Punchy Lows: The closed and ported bottom section ensures a focused and powerful low-end response, crucial for driving rock rhythms and maintaining clarity at high volumes. The porting in the 2×12 adds an extra dimension of low-frequency punch.
• Balanced Midrange: The combination of speaker types in the 4×12 model offers a well-balanced midrange response. The C90s contribute to overall clarity, while the Vintage 30s provide a distinct character that many players find desirable for rock and heavier genres. The 2×12, with its dual C90 configuration, offers a more consistent midrange character.
• Versatility: The unique split design allows the Split Back cabs to excel in a wide range of musical styles. They can handle everything from pristine cleans and ambient textures to aggressive high-gain tones without sacrificing clarity or punch.

Review

The Mesa/Boogie Split Back cabs are a welcome return to a design that offered guitarists the best of both open-back and closed-back worlds. The high-quality construction, premium Celestion speakers, and thoughtful features like removable casters make these cabinets a professional-grade choice for discerning players.

The 2×12 model provides a more portable option while still delivering a potent and versatile sound. The combination of the C90 in an open back and a ported closed back offers a balanced tonal spectrum with a focused low-end.

The 4×12 Split Back is a powerhouse, offering a massive soundstage and the distinct tonal characteristics of both the C90 and Vintage 30 speakers. The added stereo capability further enhances its versatility for players with more complex rigs.

• High-quality Baltic birch construction for durability and tone.
• Premium Celestion speakers (C90 and Vintage 30).
• Removable Track-Loc casters for easy transport.
• Versatile sonic performance suitable for various musical styles.

Cons:

Conclusion:

The Mesa/Boogie Split Back cabs are more than just a nostalgic re-issue; they are a testament to innovative cabinet design and high-quality craftsmanship. Whether you opt for the punchy and portable 2×12 or the massive and versatile 4×12, these cabinets offer a unique sonic footprint that can elevate any guitarist’s rig. If you’re looking for a cabinet that delivers both open-back clarity and closed-back punch in a single, well-built unit, the Mesa/Boogie Split Back series is definitely worth considering.
