renehollan's Journal: Subwooferitis!

Well, trying to mate a sub to my new B&G Radia 520dx speakers has proven to be a hassle. See, I'm too cheap to spring for a Velo HGS-12.

But, I came across a fellow that designs and builds subs, with a good reputation, to boot: kyle AT acoustic-visions.com (Please don't spam him, but he welcomes inquiries). With his help, and an on-line crash course in speaker acoustics (I now understand Fs and Qtc, among others), we came up with an 85l (19" cubed, outside) enclosure (Qtc = 0.6 for tight bass) for a 12" Dayton Titanic Mk. II driven by a Hypix HS 200 plate amp. Should go down to around 18Hz, room loaded.

The HS-200 is nice in it's own right: Linkwitz-Reilly cross-over, with adjustibe high and low pass frequencies (though 80 Hz for the mains is fine), infrasonic filter, and adjustable bass boost. This should be a breeze to mate with my main speakers. (Perhaps I should get two and run a stereo pair! -- nah, let's start with one).

Best part is price: under (significantly under) $1000, assembled, and shipped to my front door.

Oh yeah, the people at Bohlender Graebener are REAL nice: I ordered a set of spiking kits (they DO make a difference, esp. in tightening up what little base the Radias have). Well, instead of standard shipping, they Fedexed them second day air, but only charged me standard shipping. The difference was only around $4, and I was happy to get them sooner, but still: this is customer service at it's best (i.e. "we made a small mistake, you don't pay for it") Great company.
