Dynaudio fans, I have a question for you.
Does anyone of you have any experience with the Sub500? There is one for sale on a dutch used-products website for a decent price: http://www.marktplaats.nl/a/audio-tv...reviousPage=lr
My current sub is an Adam Sub10mkII that I run sealed, because ported really doesn't work with my Special 25's. I get some deep bass, but below 30Hz it loses efficiency quickly. There is some 20Hz output, but barely. Some movies really drive it to it's limits. It distorts badly, even before it's protection kicks in. It wasn't designed to be used sealed.
I have a plan to upgrade somewhere in the future, maybe by building my own subwoofer. Those plans are described in more detail here: http://www.diyaudio.com/forums/subwo...scanspeak.html
Ofcourse, unfortunately there are the usual problems of the availability of time, funds and the Aurasound NS12 driver I intend to use. This driver will, in theory, be capable of giving me approximately 110dB at 20Hz, due to it's HUGE Xmax. Which is probably (much) more than I need. (I do like headroom and clean output - I hate distortion; and I have no idea what -3dB figure I need to get flat in-room extension to 20Hz.)
But since this Sub500 is up for sale... It's been on my wish list for quite some time. I haven't been able to audition it yet, and I'm really interested in it's real-world performance. Can any one with hands-on experience tell me about it? How does it handle dynamic ELF passages when wide spectrum SPL averages at about 85dB? My current sub is in danger of dying at that point... And what about integration and sound quality?
Any info is very much appreciated!
