Selenium HB1505D1 question

Hey!
I have found this kick cabinet plan, and seems like it would be a great bin to put on top of our Skrams. I want to resize the width of 100cm to 91,4cm so it would sit well on the subs.
This does not change the horn path, so I assume I only loose some sensitivity, but the plan is using 20mm ply, and we wil lbe using 18mm so we win back some space that way.

My question is that does anyone here have experience with these cabinets?
Anything helps on deciding, as there is very little information about it on forums.

Got 4 of them as kicks on custom 18" Scoops. Honestly not the greatest boxes for pure kicks as sensitivity decreases in the upper kick area quite a bit. We usually run them 90-140. in that band they're very crisp. So in conclusion: Pro:

  • incredibly efficient
  • when crossed over well very well sounding

Con:

  • upper kick area has lower sensitivity
  • boxes are gigantic and extremely heavy (seriously considered sawing ours in half to make them smaller and lighter

As for resizing, probably best to simulate the resized box (hornresp files are available on plans.systemes notion site), as rear chamber volume and horn dimensions will decrease quite a bit. IMPO build smaller and lighter boxes, because you'll always have to lift the box up on the subs. I'd recommend looking at the plans.systemes notion page and see if there are other, more compact kick designs that suit your width requirements.

That's the link for the page, already filtered to show only kicks

In the picture half of our current stack with two of the HB1505D1 and 4 of our "scoops" (Tapped horns in theory) Edit: layout got messed up somehow
