Title: DFR-8 Full Range Driver Questions Post by Steve Deckert on 01/05/15 at 21:18:59 Quote:
No crossover is required or recommended with these drivers. I think the coherency and matching speed of the single point source, such as the DFR-8 greatly outweighs the multi-driver approach despite it's ability to cover the extremes better and achieve lower cone distortions at high SPL due to the power shared among 4 drivers. DFR-8's get loud enough on a couple watts to be satisfying long before cone distortions become an issue. Getting the 20-30 Hz bass without an esoteric enclosure shouldn't be a problem at least at 30Hz, however it will be greatly rolled as is the character of Acoustic Suspension enclosures. Sadly I don't have any measurements in an AS enclosure, but it should be fairly easy to model. The bigger concern is the interior of the enclosure as all sound must be reflected away from the speaker cone. The cones on these types of drivers are too thin to block sound, so everything inside the enclosure will be heard. Enclosures are "voiced" for this by removing the DFR8 and talking into the opening. Listen to your own voice and make changes to the inside of the box until you get the best sound. Not too dull, not to bright, listen for texture. Thanks, Steve |
