About the Dynacord COBRA-PWH Speaker
The Dynacord COBRA-PWH is a Planar Waveguide Basshorn built around the high-power Electro-Voice EVX 180B 18-inch transducer. Its onboard Voice Coil Tracking Protection circuit monitors terminal voltage and simulates the thermal behaviour of the voice coil, automatically reducing applied power before thermal overload can occur, while exhibiting soft switching so no audible clicks or pops are introduced. Power amplifiers up to 1200W at 8 Ohms can be used to maximise dynamic range safely. The cabinet is constructed from 18mm birch plywood with grooved and glued corner joints, a durable polyurethane surface coating, a powder-coated steel grille and a lockable transport cover. A frequency response of 30Hz to 150Hz allows the crossover to mid-high cabinets to be set between 80Hz and 130Hz depending on application.
Dynacord COBRA-PWH Speaker — buyer FAQs
What type of speaker is the Dynacord COBRA-PWH and what transducer does it use?
The Dynacord COBRA-PWH is a Planar Waveguide Basshorn loaded with the Electro-Voice EVX 180B 18-inch transducer. It covers a frequency response of 30Hz to 150Hz (-10dB), making it a dedicated low-frequency cabinet rather than a full-range system. The design focuses on delivering bass reinforcement within a purpose-built horn-loaded enclosure.
What is Voice Coil Tracking Protection on the COBRA-PWH and why does it matter?
Voice Coil Tracking Protection is an onboard electronic circuit that monitors the transducer's terminal voltage and simulates the thermal behaviour of the voice coil. If thermal overload is likely, it automatically reduces applied power to a safe level. The circuit uses soft switching so no clicks or pops are audible, and it resets automatically once the voice coil returns to a safe temperature. Amplifiers up to 1200W at 8 Ohms can be used without risk of thermal damage.
What mid-high cabinets is the COBRA-PWH typically crossed over with?
The COBRA-PWH's frequency response allows the crossover point to mid-high cabinets to be set between 80Hz and 130Hz depending on the application. Dynacord's own COBRA-4-TOP, COBRA-4-Far and COBRATOP are specifically noted as compatible mid-high partners, giving system operators flexibility to tune the crossover to suit different venue or performance requirements.
How is the COBRA-PWH cabinet constructed?
The cabinet is built from 18mm birch plywood with all corner joints and braces grooved and glued for structural integrity. The exterior is finished with a polyurethane coating described as significantly more durable than standard lacquer. A powder-coated steel grille and a lockable cover protect the driver and cabinet during transport and in demanding environmental conditions.
What should I check when buying a used Dynacord COBRA-PWH?
Inspect the 18-inch EVX 180B transducer for excursion noise or cone damage, and verify the Voice Coil Tracking Protection circuit responds correctly under load. Check the birch plywood cabinet for structural damage at the joints, and confirm the lockable cover and steel grille are present and undamaged. Every listing on this page carries a 21-day warranty covering major functional faults; the buying guide at 10kused.com/used-av-equipment-guide/ covers the full process.
