They're both vented frontloaded bandpass cabinets. They sound and perform great, but I wouldn't build them again. The 21ds115's move the stack (sub+ARCS=250lbs) around. If you're planning on making a line a cabs in front of a stage they'd all be moving all over the place if you drive them near their limits. I heard the Othorn experienced similar issues. Skram fires forward, so it doesn't 'lift' the cab when the driver is working. Quote Link to comment Share on other sites More sharing options...
rolo95 Posted May 2 Report Share Posted May 2 the Skhorn is a 24x32x54" cab with dual opposed 18 or 21" pro drivers. to minimize vibrations and walkaway of the cabinet!! lol !! it is not the walkingdead, is the walkingsub! Quote Link to comment Share on other sites More sharing options...
peniku8 Posted May 2 Report Share Posted May 2 Yea I have one. Opposed firing woofers is the way to go imo. I have a 2x10" dual opposed sub in the studio, it's great. But kinda required an even number of drivers, which makes subs quite a bit less portable Quote Link to comment Share on other sites More sharing options...
rolo95 Posted May 2 Report Share Posted May 2 Yeah, double the cost and double the weight ...blah blah... laws of physics cant change them Quote Link to comment Share on other sites More sharing options...
Domme Posted May 4 Report Share Posted May 4 @rolo95 For the moving sub problem I would recommend those anti-vibration rubber mats that you can put under washing machines. Cheap and effective. You can even cut them into smaller pieces to save cost. A washing machine is a hell of an unbalanced beast and still I've never seen one move (significantly) even after years of operation. Those mats also equalize uneven floors up to a certain degree and protect your subs from scratching. Or the floor itself if you're ever playing on parquet.

jngggggggg Posted May 8 Report Share Posted May 8 has any builder attempted to update the skram plans to factor in rebates for all the panels? I was watching a video of a boxman in the UK who was a strong advocate of this from a woodworking standpoint as you would create significantly more contact area between each panel resulting in much sturdier connections and a better build - at a price of course. Just unsure if it's actually necessarily or just an overkill? As it'll be complicated (without having SolidWorks) to modify the existing cut sheets to factor in these additional dimensions. The guy recommended 3mm recesses which can definitely cause issues if not taken into account. Quote Link to comment Share on other sites More sharing options...
peniku8 Posted May 9 Report Share Posted May 9 You mean dado joints like on this board? I use them mostly to make the assembly easier, since it's hard to get the position wrong when everything slots right into place. It doesn't help much with structural integrity unless you do like 10mm or so I'd say. I do 3mm too. Doing this without a CNC is a massive waste of time imo. I only drew a sketch on to the floor board when I built my Skhorn and went from there. 1 Quote Link to comment Share on other sites More sharing options...
h3idrun Posted May 9 Report Share Posted May 9 A few builds in here have done it I believe, I didnt bother as Peniku8 said it takes a real long time without a CNC and doesnt add that much extra strength if the rest is assembled properly. If you have a CNC and want the most epically perfect cabs possible then go for it, just add 6mm to the length of each panel and then cut the channels out 3mm on each side Quote Link to comment Share on other sites More sharing options...
Domme Posted May 9 Report Share Posted May 9 Just unloaded the wood for my 2 SKRAMs, starting the build on Thursday... oh boy 😻 Unfortunately I don't have access to a CNC router so I have go with lamellos instead. When it's finished I will probably reinforce some critical edges with glass fiber fabric & epoxy resin. That has to do for now... 2 Quote Link to comment Share on other sites More sharing options...
Tahoejmfc Posted May 9 Report Share Posted May 9 I love how many people have built these subs! Also, I just love these subs as well. https://www.instagram.com/tv/CalY8Y1Bi6D/?igshid=YmMyMTA2M2Y= 1 Quote Link to comment Share on other sites More sharing options...

Starving to see your construction pics 😻 hope you can share some audio measurements when you finish the cabs !! 1 Quote Link to comment Share on other sites More sharing options...

Got some tolerant neighbours and a wide field in front of the house, but unfortunately my mic is only built for 128dB. Should be enough for those civilized measurements, but I will try my best to make it suffer 😉 2 hours ago, Tahoejmfc said: I love how many people have built these subs!

Domme Posted May 15 Report Share Posted May 15 Hey everybody, I am wondering if and how you seal the area between your cabinet and handles, cable terminals and so on to minimize air leaks. I was thinking about using some 1mm neoprene sheet and was wondering if someone here has got experience with it or what you are using instead. Cheers!

From a build thread - that's what I did around the handle area - speaker gasket IIRC Quote Link to comment Share on other sites More sharing options...

jay michael Posted May 15 Report Share Posted May 15 Finally spent some sheckles to have a proper power panel build to run my amps on 240v which isn’t super common up here in most venues. While subtle, things felt a little cleaner and tight and amps ran noticeably cooler. We knocked some bottles off the wall of the bar which was a first so it seemed to have helped https://youtu.be/rqMiTLL15s8 1 Quote Link to comment Share on other sites More sharing options...
Ricci Posted May 16 Author Report Share Posted May 16 I do like 240v for running big / multiple amps. Just seems to do a better job in most cases. Speaker gasket tape FTW! I use that for the hatches, handles, drivers, etc...Always good to have on hand. Quote Link to comment Share on other sites More sharing options...

I use that for the hatches, handles, drivers, etc...Always good to have on hand. Interesting experiment for sure. My personal take away is use 240v if available. If you don't have access you can still get solid performance from 120v plugs, just ensure you aren't overloading your amplifiers with too many speakers. On 120v I run 1 amplifier per 2 skrams on a 4ohm load and can achieve likely 90-95% of what can be achieved using 240v. don't expect to get the most of tough 2ohm loads from 120volt. Of course with 120v you will draw twice the amperage, deal with more heat and that may but extra strain on your gear. 1 Quote Link to comment Share on other sites More sharing options...
h3idrun Posted May 18 Report Share Posted May 18 I always forget how lucky we are here in Australia to have 240v as the default. Not that i'm using enough power yet to max out the power supply anyway Quote Link to comment Share on other sites More sharing options...
