  1. 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. 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.

  3. 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

  4. Starving to see your construction pics 😻 hope you can share some audio measurements when you finish the cabs !!

  5. 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=

  6. 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.

  7. @rolo95My subs are my own custom designs. Imagine Skram with half the horn length and the driver downfiring. ARCS Wide/Focus have been replaced by their new A series, which fills the gap between point sources and line arrays less well than WiFo did imo. But Martin Audio released the Torus series, which seems very similar to what ARCS WiFo is, with some additional features. Probably in the same ~4k price range depending on your region/dealer. ARCS are quite a bit heavier than Torus though. As for SPL vs money I've been saying that 21" has been most cost effective for quite a while now, even before covid. Two 15ds115's will surely outperform a single 21ds115, but look at the price. I personally think it doesn't get much better from a cost per SPL point of view than 21ds115 or the very similar LaVoce driver.

  8. I'm pretty happy with my 21ds115 powered subs (similar to the Skrams I guess, just a bit smaller) and l-acoustics ARCS wide tops. PM90 components are obviously top of the line, but I personally prefer scalable solutions (the ARCS wide can be used as single 90x30° loudspeaker or in a fixed curvature line array with ARCS focus (15°) speakers). PM90 won't achieve uniform audience coverage over a large area, but it'll do exceptionally well for small clubs or small outdoor shows. Or when you just want higher SPL closer to the stage.

  9. The PM90 would be my go to choice if I was doing PA for a living on a budget. Other than Peters Line Array I would say its the best sounding speaker I have heard in a PA lineup. I got to hear it compared to a 10ft tall Krix pro cinema speaker and it sounded quite similar at 1/4 or less the size. PM90 only goes down to about 120hz but that is a lot of fire power in a small package. Sadly I havent started building my Skrams yet due to pricing of lumber and divorce. Hopefully will start towards the end of this year.

  10. No, even the Skram won't make a 21" driver sound like four 18". Looking at the specs it should outperform or be on par with a single 828 though, as long as the Skram has an adequate driver with adequate amping. That depends on your subs, your tops, the location and the kind of show you're producing. But I guess 2:1 is a good ratio for these kind of shows. Also, the guy you're describing had 4 18" drivers for 2 tops, so it's 2:1, isn't it? No, not really. Indoors, setting up subs in different locations will make for a better spatial average across the room. In wide rooms or outside, where some of the audience stand at the sides at a heavy angle to the PA, you'll run into lobing issues unless you stack your subs (you'd stack them center). But since your room isn't that wide and I suppose the subs were set up rather close to the side walls, you won't have to fight lobing. Also putting tops on your subs means you won't have to bring stands Even more of a reason to get high efficiency PA drivers over a bunch of cheap car audio ones. It means you'll get a few more db out of the subs within your available power.

  11. the worst is that in 2022 prices skyrocket high and salaries have not. that su.... big time. how many watts you need to feed the skram's, and what is the headroom you need to have .

  12. By saving a few bucks on drivers you'll end up having to bring twice as many cabs to a gig. You'll end up spending more on wood than you saved on the drivers. Plus having to haul more subs around. Definitely not worth it imo, not even taking the difference in sound quality into account.

  13. I have Memphis Car Audio SR10S8 in mine, they are just <$100 basic car subs that I had laying around so obviously have nowhere near the power handling or sensitivity of the proper PA drivers these are made for but the frequency response looks similar to other graphs in this thread Only modifications I made was omitting some bracing and cutting 4x 10" holes instead of 1x 21" hole. If you search my previous comments in this thread there's a bit more info
