WalledSonic Posted September 18, 2017 Author Report Share Posted September 18, 2017 Here's the box for the 8's. Port area is good, build log coming soon. Triticum released his port area thread around the time i was designing this box in WinISD. Had to make an emergency change on the port design but it came out good!

RedFred Posted September 18, 2017 Report Share Posted September 18, 2017 Very cool thread... I just sold my AMM-1, and I've never heard of the IM-SG. Gonna have to look into and see what the thing can do. Link to comment Share on other sites More sharing options...

WalledSonic Posted August 7, 2018 Author Report Share Posted August 7, 2018 Its been a while. Figured I'd provide a comparative Impedance Plot of my old PSI Platform 2 15s versus my new Fi SP4V2 15s. Again, taken with the IM-SG. The plot shows measured values in green and red, and calculated values in blue and purple (to simulate what my 2 amps see). Both sets of subs were very broken-in when I took these measurements. Not sure what about the subs makes the SP4 unload at a higher frequency than the PSI's, but the data dont lie. Very interesting how the curve is much smoother with the Fis. The 36Hz blip (green) from the PSIs is now gone, yet the box hasnt changed. Now I'm curious if that really was a standing wave or something to do with the PSI subs TS parameters. Thoughts? Interest? If anyone wants the spreadsheet, hit me up. Its plug n play. Plot updates live.
