Murmel Posted February 6, 2019 Share Posted February 6, 2019 Skhorn with one or two ports blocked. Do you have an amp already? Quote Link to comment Share on other sites More sharing options...
Leimahmood Posted February 6, 2019 Author Share Posted February 6, 2019 i have qsc rmx5050 looking for dual sub Quote Link to comment Share on other sites More sharing options...
Murmel Posted February 6, 2019 Share Posted February 6, 2019 Dual loaded or two single loaded? Ricci is in the design process of a single driver version of the Skhorn, don't know when it's gonna be(or if, but probably from the very generous person he is) it's gonna be available, last time I read something about it it was rather close to being finished tho.

Leimahmood Posted February 6, 2019 Author Share Posted February 6, 2019 two single loaded mean two sub with one in each b&c 21 driver Quote Link to comment Share on other sites More sharing options...
Leimahmood Posted February 7, 2019 Author Share Posted February 7, 2019 do rmx5050 will do a good job on othorn Quote Link to comment Share on other sites More sharing options...
Ricci Posted February 7, 2019 Share Posted February 7, 2019 It should be fine powering 2 21SW152. For HT in a home you may want to build a simple ported box with a tuning in the 15-20Hz range. 1 Quote Link to comment Share on other sites More sharing options...

I'm going to work on it again soon but it will probably take me months to get the SW's design and prints done and it may not be what you are looking for anyway. It's not supposed to be a HT sub. I wouldn't wait on it. Quote Link to comment Share on other sites More sharing options...

Father Francis Posted February 9, 2019 Share Posted February 9, 2019 I’ve never really seen, any need for putting subs more than 50cm from the wall if they are not ported in the back , Quote Link to comment Share on other sites More sharing options...

I wouldn't wait on it. I'm curious as to what you were thinking of. One dead simple idea is to just take the double driver Skhorn, cut it in half and add a 3/4" wall where the center used to be along with maybe some extra bracing. An additional idea would be to make mirrored pairs of these along with tensioning buckles or other hardware to bind a pair together into a temporary D.O. sub. You'd want some soft material between the cabinets so that they can be bound together tightly without any buzzing or rattling. So basically a pair would get you a Skhorn that you can more easily move as two separate parts. What's not to like? I think the hard part would be finding what kind of binding hardware works best. Something ratcheting might be a good idea. Maybe nylon strip like for tying down loads? Ideas... Quote Link to comment Share on other sites More sharing options...
