akuma4u Posted March 9, 2019 Report Share Posted March 9, 2019 hey , i am thinking of picking up two of these 12s and running them sealed off 1750-2000rms.. i specifically want to know how loud these can get and how low they will play in a sealed enclosure that is build to spec (i can go a little bigger than spec as well but not much). These call for 1.15 per sub sealed. so if someone can graph these for me.. that would be much appreciated!

CstrokerV Posted March 9, 2019 Report Share Posted March 9, 2019 You can’t really tell how loud something will get by a graph and being sealed you will lose output and sealed boxes aren’t meant for lows in my opinion my build http://www.stevemeadedesigns.com/board/topic/142505-small-build-log-4-dc-lvl3-10s-tl-update-link-to-rebuild/ http://www.stevemeadedesigns.com/board/topic/154258-rebuild-6-lvl3-12s-update-small-video-nothing-spectacular/ new build http://www.stevemeadedesigns.com/board/topic/188181-03-trailblazer-slow-build-8-dc-lvl3-12-m1-motor-m2-parts/ Link to comment Share on other sites More sharing options...

CstrokerV Posted March 10, 2019 Report Share Posted March 10, 2019 If a sealed box hit lower then a ported box the ported box wasn’t built right and the tighter and cleaner isn’t always accurate either my build http://www.stevemeadedesigns.com/board/topic/142505-small-build-log-4-dc-lvl3-10s-tl-update-link-to-rebuild/ http://www.stevemeadedesigns.com/board/topic/154258-rebuild-6-lvl3-12s-update-small-video-nothing-spectacular/ new build http://www.stevemeadedesigns.com/board/topic/188181-03-trailblazer-slow-build-8-dc-lvl3-12-m1-motor-m2-parts/ Link to comment Share on other sites More sharing options...
k58.cross Posted March 11, 2019 Report Share Posted March 11, 2019 I used the ts params you posted up there and got the -3 dB point at 48 Hz. SPL wasn't very high in a sealed box of 2.3 cubes (for 2 subs) maxing at 116 dB (not considering cabin gain). But there were some ts params not included, not sure if they would make a difference. Honestly for $270 each, that's not much power handling, unless they are under-rated. I'm not familiar with this brand. Also, it says up to 150 DAYS wait time....Damn I could not wait that long myself. I'd suggest Deaf Bonce or Sundown, I've used both and they're great. Deaf Bonce will be a bit cheaper, Sundown more rugged. Edit: Just noticed SA V3 12's are on sale for $195 right now. That's a "750 wrms" sub, but I'm sure you could easily slap it with 1k.
