   Thanks for the responses to you both - have been digging around a bit and considering the Othorn loaded with the 18SW115's. Does anyone have experience with these drivers in these cabinets?

	You’re going to need to pole mount the PM90 for reasonable elevation. If you’re doing that, with an M20 threaded insert in one cabinet end, then add some extra handles on that side and the opposite. You’ll appreciate it, especially if moving things alone. For a small stack, with lower extension than both the Keystone and XoC1’s TH18 and some variation to other rigs, I’d personally look at this design which has really nice AutoCAD drawings: https://www.diyaudio.com/forums/subwoofers/232219-325-lab-12-based-pa-tapped-horn-35hz-extension-54.html Extra details here: https://www.diyaudio.com/forums/subwoofers/232219-325-lab-12-based-pa-tapped-horn-35hz-extension-55.html It’ll be relatively heavy, but you get a height of 1.546 metres which is much more friendly for ground stacking with a pallet or stage deck underneath. You can always split the box down the centre line and build them as singles - which also avoids the need for 5’ x 5’ sheets. You can also leave out the ‘cone correction’ and make all of the corner reflectors simple 45 degree angles. Changing the external width to be 584 mm probably won’t make much difference to the output, but will make them super van & truck pack friendly. Those are basically the dimensions of a KS28, which is built for touring. That makes it a pretty easy build. Edited by toastyghost - 20 September 2021 at 3:51pm

	Can confirm that th18 with castors is very easy to move by myself, even load and unload from car height is doable. It has a 45 degree panel on the back to fit wheels that will not protrude from box shape. If you go with th18 put some handles behind the upper reflector on the back!

	Depends on your definition of "move solo". If you have decent casters, even surfaces to roll them on & suitable ramps for vehicles then even fairly big bass bins like the Keystone or TH-18 can be moved around solo surprisingly easily. I weigh under 70kg's and I can shove these around ok on level enough surfaces. Stacking them definitely takes more bodies though.

	Hey all, Looking for some enclosure recommendations for the 18SW115. Some notes below. System will be used to play primarily house & techno, Have 4 x 18SW115's to be housed Sub amp is an MC2 E90 Subs to be paired with 2 x PM90's We originally set out to make a system that was compact enough to move solo. But it's beginning to seem as though the SPL / range compromises won't be worth it for a cabinet that can be installed solo. We originally were thinging 4 x S18BN's - but reading around the reviews don't seem to be exceptional. Current front runner alternatives were either Keystone or Xoc1's TH-18. Would love to hear opinions on these cabs, or any suggested alternatives.
