Up for sale is a beautiful Dali Helicon S600 Subwoofer in excellent condition. The Helicon S600 enclosure is made according to the same principles as the other Helicon speakers – very strong laminated panels, veneered and high gloss polished. The beautifully curved top can also act as a perfect cradle for the Helicon C200 center speaker. In a stereo set-up, the importance of a subwoofer is often underestimated. It is regarded as an option, rather than a necessity. However, in listening sessions with direct comparisons of a stereo set-up with and without a subwoofer, it is commonly agreed that a subwoofer increases the overall sound quality significantly. All we can do is to advise you to listen to stereo with and without a subwoofer and then make up your own mind. In surround, there can be no doubt about the need for a subwoofer. You need deep bass to reproduce explosions, car chases, etc. when viewing movies. The S600 has two 12” long-throw drive units firing sideways in opposite directions in the sealed enclosure. Powered by a powerful 300 Watt amplifier. The S600 is capable of a maximum SPL of 117 dB from 25 Hz. This is a subwoofer not only to be heard, but also to be seen and felt. S600 is the ideal stylish subwoofer for your Helicon (or any other) stereo or surround system. It will be a great addition to your home theater system.
