The single 4 Ohm Anarchy with 10" PR in .6 cubic feet would work well since the 8 Ohm is apparently out of stock.R = h/(2*pi*m*c) and don't you forget it! || Periodic Table as redrawn by Marshall Freerks and Ignatius Schumacher || King Crimson Radio

Pete, how much added mass are you looking at for the PR? I ran some sims in Unibox that look really good but I haven't seen any information on how much mass the DS PR can accommodate.Comment

What are you seeing for the F3 & Fb? What are you using to model them?
I am using Unibox to model the 4 ohm in .6 CFT and I am having to add a lot more mass. I think I am using the T/S parameters that you posted but I may still be doing something wrong...Comment

I was using WinISD and the parameters pulled from the PE website for the SDA270 PRs. The pair of them tune 1cf to 41Hz which in this simulation produces F3 at 38Hz. But that's with a pair of 8 Ohm.
Using the parameters I measured for the 4 Ohm Anarchy, and the same 120 grams on a single PR in .6cf, F3 extends to 35 but with an EBS alignment (shelving of the bass response). Nothing at all wrong with that.R = h/(2*pi*m*c) and don't you forget it! || Periodic Table as redrawn by Marshall Freerks and Ignatius Schumacher || King Crimson Radio

Who's using them,,,count me in.
Super woofers....fabricated several boxes and now using three MTM's in the HT.
(pic)
The woofers are beautifully made and with a few crossover (passive) parts have a very nice, flat response.
*Don't even bother to turn on the subwoofer on most of the time..
Actually I wonder why more people are lined up to try them.1 PhotoLast edited by HIFY GUY; 01-13-2019, 01:42 PM.Comment

They also work well in a .5cf sealed enclosure."He who fights with monsters should look to it that he himself does not become a monster. And when you gaze long into an abyss the abyss also gazes into you." Friedrich Nietzsche
