Joe X Posted April 24, 2014 Report Share Posted April 24, 2014 You could do the following for those subs, power: to subs rated, amp subsonic filter to 28Hz, port clearance 5", figure is just an assembly guide, bracing is 1 1/4" wooden dowel rod, standard 3/4" MDF for the port brace: Link to comment Share on other sites More sharing options...
jdshott Posted April 25, 2014 Author Report Share Posted April 25, 2014 So I am open to different subs . And yes running between 0.9 and 1 ohm . My price range is questionable. I have looked at a lot of the subs available and I am not impressed with the engineering of the components I.E. foam surrounds don't last in Texas weather (DC Audio . SoundQubed. Sundown) All foam surrounds and I Have never used a sub with copper coils . No 1 But me paid for this stuff and NO FREEBIES so no brand names (No Free Advertisement ) A SQ head unit 6 5.25 2 X 6x9s 7804 P400.4 4001D 1 34s (Maybe time to change brand) 4 X 15" s !/0 @ 2/0 OFC Wiring :morepower1: :morepower1: ill say it like i always say it. F##K the DD-1. I don't care if you or anyone buys one. (well i do, but that isn't my point) Get an O-scope in the very minimum and learn how to use it or you are just guessing your settings like every other noob. once you master the O-scope then step up to a DD-1 or even better a DD-1 Plus.

Joe X Posted April 25, 2014 Report Share Posted April 25, 2014 THANK YOU Joe X !!!!!!!!! When I get a chance to build this I will post pics . You're welcome, it will improve over your current box some but the best advice is upgrading subs - definitely - You may use 4 Sundown SA-15s on the box above without any modifications and it would be a compelling upgrade. If you have any questions let me know. Link to comment Share on other sites More sharing options...

Guest Posted April 25, 2014 Report Share Posted April 25, 2014 http://www.soundqubed.com/HDC415-D1-A_p_136.html 2 of these, not 4, 10-11net 180sq" port, 35-37hz should come close to a 34x25x30 box assuming OP uses 7000w, this will smoke everything op is talking about. instant 150s Link to comment Share on other sites More sharing options...
Guest Posted April 25, 2014 Report Share Posted April 25, 2014 no idea what he's talking about...never heard of GOOD foam surrounds tearing because of heat and humidity Link to comment Share on other sites More sharing options...
jdshott Posted April 25, 2014 Author Report Share Posted April 25, 2014 I never said tearing , my issue would be deterioration over time . I dont have desposable money, so to buy subs, just to test them is out of.the question in my case. although i would LOVE to try (Sundown, SoundQubed, and DC Audio) Amongst others . This is just My opinon because all the subs i have used in the last 15 years all had rubber surround... (BTW Please DO NOT trun this into a V.s. ) but im all ears on personal opinions and experances No 1 But me paid for this stuff and NO FREEBIES so no brand names (No Free Advertisement ) A SQ head unit 6 5.25 2 X 6x9s 7804 P400.4 4001D 1 34s (Maybe time to change brand) 4 X 15" s !/0 @ 2/0 OFC Wiring :morepower1: :morepower1: ill say it like i always say it.
