Features
The Lotusline SW15 is a subwoofer designed with the latest state of the art simulations tools in terms of acoustic quality, mechanical strength and optimized cooling. The SW15 incorporates one high excursion and low distortion 15-inch driver installed in direct radiation enclosure and loaded by a critically damped bass reflex incorporating multiple vents (MVC™ technology) for a better cooling. The 15-inch transducer has an 3 inch (76 mm) copper sandwich voice coil on black Kapton former for low power compression and double treated cone for water protection. Triple demodulating rings combined with 8mm excursion capability, die cast aluminium basket, massive vented magnet structure offer the best performances even in very low frequencies. Its power handling capacity of 500 W (AES) long term and 2000 W (Peak) all other the usable frequency bandwidth from 43 to 500 Hz (± 3 dB) offers a permanent 123 dB SPL and 129 dB SPL peak. The loudspeaker enclosure constructed of 18 mm birch plywood with internal braces remains free of vibration at extreme sound pressure levels. The enclosure has 2 aluminum integrated handles on the sides and can be fitted with 4 optional rigging parts on the sides.
Applications
The SW15 is ideal for applications requiring compact subwoofers with low frequency extension and impact. The SW15 is the companion subwoofer for CL16 array and can be installed at the top of the line. It is also possible to use top to tail configuration to get a cardioid front oriented directivity system, eliminating unwanted reflections. Due to its compact design and critically damped tuning, multiple SW15 enclosures couple effectively while providing the bass definition and musicality that only a direct radiating subwoofer can provide. Different low pass crossover presets allow to optimize the power distribution of the whole PA system. The SW15 provides a very dynamic and punchy sound reproduction for the sound effects that are commonly found in electronic music where the whole dynamic capacity of systems is used. This subwoofer offers full flexibility for low frequency reinforcement of Lotusline speakers and Line Array systems.
