The Dali SWA 8 could be the woofer you've been looking for if all you need as far as the low-frequency response is concerned is serious sonic quality and reliable operation and are not looking for either house-wrecking volume or quaking bottom-end loudspeakers.
Indeed, the The Dali SWA 8 is a subwoofer for those who like the good sound of their music and movies without caring too much about other issues which are in the audiophiles' everyday topics; it will offer you good sound at a very affordable price and will provide you with neat LF response... exactly what you were looking for.
The The Dali SWA 8 Subwoofer can be matched with other Dali loudspeakers or can come as a completing element in sound systems made with other brands' speakers – in either case it will do a very neat job, well worth every penny. The The Dali SWA 8 Subwoofer can also be added to both multi-channel surround sound systems as well as used in stereo applications, for more present bass and an overall richer sound.
Despite the fact that the Dali SWA 8 sports a closed cabinet architecture, its response is not at all “chocked” or boomed like in the case of lower quality subs; aucontraire, the LF reproduction is clear and clean as the long-throw woofer can really move a lot of air (like larger units do) yet the bass-blast sports a fast attack and tight punch (a characteristic of smaller-diameter woofers).
This air-dried pulp cone-subwoofer can deliver you sound between 30 and 150Hz creating as much as 107dB sound pressure level and can handle a max power of 120W. While being capable of working with both line and speaker level low-pass filtered signal, the The Dali SWA 8 Subwoofer can also handle mono LFE runs. Even more, you get crossover and phase adjustment controls so this bass machine will sound as good as possible in your room.
