DVS 118 SW iSP

Compact self-powered subwoofer



High-efficiency self-powered subwoofer (1500 W EIAJ, PWM power amp module).
1 x 18″ long-excursion low frequency transducers featuring innovative technologies to provide premium electro-acoustic performance to reliably deliver very high SPLs over extended periods.
Very high power handling (2800 watt AES peak) and maximum sound pressure level (142 dB SPL peak at 1 metre in half space)
Equipped with Outline’s iMode technology, providing complete monitoring and control via any Ethernet connection.
Direct control of all Outline iMode enabled speaker systems via iPad, iPhone and iPod Touch (with dedicated app).
Real-time control over a series of parameters – levels, delay, eqs, shelving filters and group functions.


The DVS 118 SW iSP is a single 18″ subwoofer enclosure using phase inversion type loading, which, coupled with the use of several innovative loudspeaker technologies, allows it to deliver consistent performance at the highest levels over many years. The particular aspect of 4th order loading enables a wide band pass and great extension towards the bottom end of the frequency response. The high quality components used, allow a useable bandwidth reproduced at -10 dB from 26 Hz to 118 Hz, with remarkable linearity: +/-3 dB from 35 Hz to 82 Hz (factory preset), this enables the system to be used in a wide range of applications for sound reproduction from low to mid/low frequencies. The maximum continuous AES power of 700 W gives 132 dB SPL in half space while peak values even reach 142 dB SPL. The DVS 118 SW iSP’s high quality build finish is constructed from 18 mm (phenolic-glued) Baltic-birch plywood. The outer finish applied is a scratch resistant, waterproof black paint and the front of the cabinet is protected by an anti-resonant steel grille.
There is a receptacle for mounting the optional support of a satellite (if used); integral handles and an optional trolley facilitate transport, even on uneven surfaces. The high-efficiency amplifier is able to deliver a total of 1500 W EIAJ power to the transducer. The system embodies the iMode technology, thus allowing a comprehensive and reliable control and monitoring.



All the DVS iSP series is equipped with Outline’s proprietary iMode technology. Utilised extensively throughout the Outline range, iMode is a truly “intelligent” digital loudspeaker control platform which combines advanced digital signal processing and TCP/IP protocol to provide comprehensive control capabilities and a huge choice of interface devices. Users have real-time control over a series of parameter (levels, delay, eq’s, shelving filters). iMode also allows the user to monitor performance parameters throughout the system (including VU-meters, clip and limiter status, amplifier overheating and protection) by using an iPad with dedicated Outline app. With standard IP-based communication, the iMode platform is truly future-proof, offering control via netbook, smartphone, and many devices yet to appear. iMode operates on a Linux operating system with an Outline-customised kernel, chosen for its extreme stability and compatibility, and providing a robust foundation for iMode’s advanced functions.
