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. 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... I don't have enough knowledge about designing horns to be talking about this with confidence, but since the horn opening angle would drop to 6° from 12° if simply cut in half and adding a side panel the interior would need to be redesigned. That is if a horn works the way I think it does, if it doesn't please call me out. As for binding hardware butterfly latches would be great. I actually posted about this modular cab idea using butterflies on AVS some time ago but nobody seemed to be into it. You could even saw the original SKHorn in half and slap like 6 butterfly latches on that to combine it. Use weather stripping to seal it and you have your modular SKHorn. I wonder what it would sound like if just left in pieces But I think we're going slightly off topic here, that could be discussed in a new thread Quote Link to comment Share on other sites More sharing options...

Velmeri Posted July 14, 2021 Report Share Posted July 14, 2021 (edited) I cant say anything about inches but i Have single 21sw152 in My living Room. The box IS 430l (0.43cubic Meters) and reflex point IS about 14.6hz. It has 3 vents witch IS 110mm Wide and about 950mm deep. it yousually Works very fine but when It Goes upper bass, Ports can Make noise (sorry For My Bad english and i am little bit of drunk) Edited July 14, 2021 by Velmeri Quote Link to comment Share on other sites More sharing options...
Antso Posted September 8, 2021 Report Share Posted September 8, 2021 So how this all ended up? I just received my 21SW152-4, and plan is to pair it with my two cubo18 loaded with RCF L18P400. Mostly for listening all kind of music at home but now and then weddings and other partys a bit louder. All I want that the 21" would do, is going ~35hz to down low as down as possible. There is that one drawing, but with slotted port calculator its tuned way too high? Or am I missing something? Wanna try something simple with one port this time tho.

I wonder what it would sound like if just left in pieces But I think we're going slightly off topic here, that could be discussed in a new thread To answer my own ramblings from 3 years ago, since I know better now and I couldn't just leave this as is: since the two drivers fire into the 12° horn in a mirrored fashion, they will each behave as if they were loaded into a separate 6° horn. Sawing the Skhorn in half will technically work just fine. Most hardware rattles and I think it would be really hard to keep butterfly latches under control, so that idea is sadly also a dud. And no more wondering what it would sound like after sawing it in half without adding new side panels: it becomes a vented cab with lots of wasted extra space and a really silly driver mounting.
