BishopSound GAMMA 10

The Professional’s Choice — Built for Touring. Designed for Installation. Engineered in Britain.

The BishopSound GAMMA 10 is a serious professional loudspeaker engineered for companies that demand reliability, clarity, and long-term value. Designed and manufactured in Britain, it delivers the performance touring engineers expect and the durability installation companies require — without compromise.

This is not a budget speaker. It’s a professional tool built to outperform lightweight plastic alternatives and low-cost imports, while delivering consistent, high-definition sound in both portable and fixed applications.

Why Professionals Choose the GAMMA 10

Built for Touring

Robust ABS cabinet construction, professional components, and road-ready durability make the GAMMA 10 ideal for hire stock, mobile production, and touring applications. It is designed to withstand transport, stacking, and daily deployment while maintaining consistent performance.

Designed for Installation

Clean voicing, controlled dispersion, and a compact footprint make the GAMMA 10 perfect for fixed installs in venues, houses of worship, bars, schools, theme parks, and conference spaces. It delivers even coverage, excellent intelligibility, and dependable long-term operation.

British Voicing

The GAMMA 10 is tuned for clarity and musical accuracy. Vocals are forward and intelligible, midrange remains natural, and high frequencies stay smooth even at high output levels. The result is a refined, fatigue-free sound that cheaper copies simply cannot match.

Professional Output, Compact Format

Delivering impressive SPL from a compact enclosure, the GAMMA 10 reduces truck space, rigging weight, and installation footprint while maintaining powerful full-range performance. Ideal for both primary PA and distributed systems.

Built to Last

Durable construction, purpose-designed components, and careful quality control ensure long service life — essential for rental companies, touring engineers, and permanent installations.

• Engineered for Real-World Performance
• Intelligent HF protection crossover
• Responsive, punchy low-frequency performance
• Flat, balanced frequency response

The GAMMA 10 delivers true high-definition sound with minimal distortion, even at high output levels, making it ideal for both music playback and speech reinforcement.

Indoor & Outdoor Reliability

Designed and engineered in Great Britain, the GAMMA 10 is one of the most respected polycarbonate ABS loudspeakers for indoor and outdoor use. The sealed enclosure resists moisture and environmental wear, making it ideal for demanding installations.

Whilst not IP-rated, the GAMMA 10 is widely used across UK seafronts, piers, amusements, fairgrounds, and outdoor venues where reliability and weather resistance are essential. The sealed cabinet prevents moisture ingress and eliminates the degradation of wooden enclosures often associated with them.

Acoustic foam behind the powder-coated steel grille further reduces water ingress while protecting internal components.

Custom Engineered Transducers

The GAMMA 10 features purpose-designed British-voiced components developed for clarity and reliability:

• BishopSound 10" ferrite driver
• 2.5" high-temperature voice coil
• Titanium HF compression driver
• Wide dispersion constant-directivity horn
• Optimised passive crossover network
• High-quality capacitors and copper coils

This combination produces smooth highs, defined midrange, and controlled low frequencies with excellent projection across the coverage area.

Intelligent Protection & Reliability

The GAMMA 10 uses a carefully designed internal crossover with HF protection circuitry. This automatically limits high-frequency driver stress, reducing the risk of damage from over-driving. Combined with the responsive LF driver, the system remains clean, controlled, and reliable at all output levels.

This design philosophy has delivered exceptional long-term reliability in touring, installation, and fairground applications.
