CECAA850 Posted December 21, 2012 Share Posted December 21, 2012 The recommended placement for the THT is away from a wall with the mouth toward the mouth, thus taking up a lot of room. That must be the new THT donut configuration[]. Quote Link to comment Share on other sites More sharing options...
Quiet_Hollow Posted December 21, 2012 Share Posted December 21, 2012 I would think that the F-20, SPUD clone and Lab-12TH would all be close in price and performance as well as being easier to build. "...Yeah....I'm going to have to go ahead and sort of disagree with you there." Everything considered...I stand firmly behind what I said.

Quiet_Hollow Posted December 22, 2012 Share Posted December 22, 2012 My appologies if that came off a little brash...it's just that I've been around the block with the DIY tapped horns and other DIY designs too. While the F-20, SPUD clone, and Lab12-TH would all be excellent choices for a kick-butt home theater system, the design process falls a little bit short when pressed into music service. The SPUD certainly isn't cheaper. The Lab12-TH won't filter any harmonics (been there, done that). And the F-20 doesn't cover any new ground that the THT hasn't already been on. Then there's some mechanics of the the Lab12-TH and F-20's cabinetry that could use some polish. It's not how they perform in the sub bass region that's the problem, it's how they behave on the upper side of their band pass that makes or breaks the design when it comes down to playing music and working well with the mains they're supposed to supplement.

If you're referring to bracing, I agree. I added bracing to the F-20 I built and the cabinet is every bit as inert as any sub I've seen. It's not how they perform in the sub bass region that's the problem, it's how they behave on the upper side of their band pass that makes or breaks the design when it comes down to playing music and working well with the mains they're supposed to supplement. I didn't have any measuring equipment when I built the F-20 but I did have the ability to adjust the cut off frequencies of the upper end of the signal going to the sub. Once dialed in, it was very musical (to me) and I'm fairly critical. If it didn't sound good to me. I'd have no problem saying so. I wouldn't defend it just because I built it.
