Beyma 18WRS600 18" High Output Subwoofer

Beyma 18WRS600 18" High Output Subwoofer

The 18WRS600 features a 3” copper voice coil with optimized pressed steel frame, extended controlled displacement (Xmax ± 8.5 mm), 53 mm peak-to-peak excursion before damage, and is optimized for direct radiation subwoofer applications.

• Low distortion 18” subwoofer
• Power handling 1200 W program power
• Exclusive Malt Cross® Technology Cooling System
• High sensitivity: 97 dB (1W / 1m)
• FEA optimized ferrite magnetic circuit
• Ultra low air noise
• Optimized linear behaviour
• Weather resistant cone with treatment on both sides

Madisound suggests a 4.75 to 6.0 cf3 sealed box for F3 of 55Hz.

The total SPL that can be obtained with these drivers has been significantly increased, because we worked in new suspension systems, able to increase the linear motion of the moving assembly; new membranes with special fiber loaded pulp cones, treated in both sides to resist humid weather conditions, and new motor structure designs with our exclusive Maltcross® cooling system and new voice coils which assure high power handling capacity from the drivers, which combined with the high sensitivity of every model, can result in probably  the most competitive high SPL 3″ coil woofers in the market at the moment, with first quality materials in every aspect and a careful design and manufacturing made in Spain.

Since 1969 Acustica Beyma designs and manufactures from its factory in Valencia a wide range of solutions in the loudspeakers field. Beyma is one of the most reliable company in the audio sector and it is considered as one of the main worldwide firms.

Notes:

1. The power capacity is determined according to AES2-1984 (r2003) standard.
2. Program power is defined as power capacity + 3 dB.
3. T-S parameters are measured after an exercise period using a preconditioning power test. The measurements are carried out with a velocity-current laser transducer and will reflect the long term parameters (once the loudspeaker has been working for a short period of time).
4. The Xmax is calculated as (Lvc - Hag)/2 + (Hag/3,5), where Lvc is the voice coil length and Hag is the air gap height.
