Ricci Posted August 26, 2020 Author Report Share Posted August 26, 2020 You could do something similar and shrink the cabinet and slot volume somewhat to better fit the 18". The 18 doesn't need as much airspace to work in. Quote Link to comment Share on other sites More sharing options...

Chris Posted July 8, 2021 Report Share Posted July 8, 2021 Hi all I am looking at a DIY FOH build. For the top boxes looking at the Peter Morris PM90 and was wondering if this sub in two per side would be a good match. I plan to bite the bullet and spend once so the Eminence NSW6021-6 will be the driver. On that what would be ideal power amps to run the show Chris Quote Link to comment Share on other sites More sharing options...

I've not personally heard the PM90's but I've looked at the design and talked with guys who have built and heard them. The feedback and measurements are positive. Amplification will depend on budget, channel needs and available mains supply. You've got everything from Behringer at the cheap end on up through something like a PS X8. Would the PM90,s be active?

Nicholas Posted August 8, 2021 Report Share Posted August 8, 2021 Is the front panel necessary or can i use without it? How does affect the frequency response? Quote Link to comment Share on other sites More sharing options...
Ricci Posted August 9, 2021 Author Report Share Posted August 9, 2021 You can use it as a vented cab without the front panel. It is designed to be used either way. If you read the initial (LONG) posts I made it goes into some detail about what the front panel "should" do. I never had a chance to fully GP test this cab design yet.

CoastalJay Posted September 29, 2021 Report Share Posted September 29, 2021 With a massive shortage of available drivers, the Dayton PSS545 Velocity models quite well. I am going to try it and build 1, any chance of the DXF files to make my life easier on the CNC? Thank you Jason Quote Link to comment Share on other sites More sharing options...
Ricci Posted October 5, 2021 Author Report Share Posted October 5, 2021 CJ, Everything is in the first couple of posts. FYI. The Dayton has a large amount of inductance. It will modify the performance significantly if the effects weren't included in the model. Quote Link to comment Share on other sites More sharing options...
M88@FL450 Posted October 6, 2021 Report Share Posted October 6, 2021 Any Burst Output numbers to compare to SK and Skram? This is a great design without leaving much on the table for size. Quote Link to comment Share on other sites More sharing options...

Ricci Posted October 13, 2021 Author Report Share Posted October 13, 2021 I do not have DXF files developed for this. Your CNC provider would need to roll their own. This is the simplest design though. It shouldn't be very difficult. Quote Link to comment Share on other sites More sharing options...
Victor Posted November 25, 2021 Report Share Posted November 25, 2021 First post on this forum, hi Guys! Really like all the content here and wish I would find it sooner. Looks like a pair of Ckrams is my next dream build. Big thanks for the design and detailed information! Frankly would prefer to build Scrams instead but the size and weight scares me (me and my spine, to be precise), don't think I can handle it. The biggest sub I built so far is vented B&C 18DS115-8 and so it's very interesting for me to see how a couple of NSW21 in Ckram cabs will sound. I will do some measurements after I'm done and will post here. Quote Link to comment Share on other sites More sharing options...
Ricci Posted December 3, 2021 Author Report Share Posted December 3, 2021 Excellent Victor. Welcome to the forums. I look forward to your build. Quote Link to comment Share on other sites More sharing options...
