IH8PunkRok Posted May 24, 2012 Report Share Posted May 24, 2012 im going to be trying a modest sq system i want to try 8s for the substage they will play only 20-55 hz the front stage will handle the rest however i want it to be flat. all the way down. is there a good way or rather a proven way to keep those sub frequencies from dying out with little speakers? -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build Link to comment Share on other sites More sharing options...
Narwhal Posted May 24, 2012 Report Share Posted May 24, 2012 You can use WinISD to get a frequency response graph for a box that you make. Getting down to 20 might be a bit difficult Link to comment Share on other sites More sharing options...
BobbyG2 Posted May 24, 2012 Report Share Posted May 24, 2012 I'd take a look into the TC Sounds Epic 8". http://www.parts-express.com/pe/showdetl.cfm?Partnumber=293-657 *New vehicle and system coming soon.* Link to comment Share on other sites More sharing options...
IH8PunkRok Posted May 24, 2012 Author Report Share Posted May 24, 2012 i have bassbox which i trust more than winisd why do you recommend the epic? -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build Link to comment Share on other sites More sharing options...
BobbyG2 Posted May 24, 2012 Report Share Posted May 24, 2012 Low fs, high xmax, models well at least in WinISD, I've heard great things about their SQ, and can say with experience with the 10" version that they are very clean sounding subs. *New vehicle and system coming soon.* Link to comment Share on other sites More sharing options...
IH8PunkRok Posted May 24, 2012 Author Report Share Posted May 24, 2012 Well here Is the thing. I do believe that with the high xmax it can handle the lows like I need it to but I'm not completely convinced. I could get two tang bands for the same price and I know those perform -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build Link to comment Share on other sites More sharing options...
Sanitarium Posted May 24, 2012 Report Share Posted May 24, 2012 try modeling up a low tuned 6th order and see how ya like it (just a suggestion) Link to comment Share on other sites More sharing options...
IH8PunkRok Posted May 25, 2012 Author Report Share Posted May 25, 2012 its giving me interesting results. but ported is still coming out on top the problem im having is vent velocity i have a confined space to work with. about .8 cubes per sub (i have little pockets i want to fill up in the back) and in order to get the tuning low enough i need to use a very small port. which causes massive vent velocity ie port noise -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build Link to comment Share on other sites More sharing options...
