alenv10 Posted January 10, 2014 Report Posted January 10, 2014 Single soundqubed hds312 2 cubic feet lot of port area 34 htz anything im missing? other than displacement which i dont know what it is for the hds312 NOTHING DOWN HERE YET OBSIDIAN FTW
youngbass98 Posted January 10, 2014 Report Posted January 10, 2014 I dont know what the exact displacement is but would assume it is around .2 06 monte carlo 2 12 rockford p3s soundstream rubicon 2500 crescendo audio mezzo 6.5 ct sounds 125.4 execution audio and shca wiring 2 xs d3400 on stock alt
ChrispyShimp Posted January 10, 2014 Report Posted January 10, 2014 It would help us help you if you listed the exact brand, model, and size/ohm/voicecoil(s) of the subs. The TS parameters of the sub are almost as important as box parameters, knowing the brand and model will help us find the parameters. Also, Might I suggest building a 3-D model of the box first in the free Google Sketch-up, Here's a link to a how to video to get you started https://www.youtube.com/watch?v=ZCeUB63Sjks Hope this helps, good luck. Knowledge is the greatest tool in any garage. It's also the most priceless, and most easily shared. Here's my latest build. http://www.stevemeadedesigns.com/board/topic/181273-89-c1500-build-log/
alenv10 Posted January 10, 2014 Author Report Posted January 10, 2014 I know how to design it with google sketch up. i was asking about the frequency, port volume, box volume. soundqubed hds 300 12" D2 NOTHING DOWN HERE YET OBSIDIAN FTW
alaskanzx5 Posted January 10, 2014 Report Posted January 10, 2014 Avoid more then 1 port bend with slot Ports to, port bends can hurt port efficiency. less bend the better. t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.
alaskanzx5 Posted January 10, 2014 Report Posted January 10, 2014 bracing or a double baffle and the box will need to be a but bigger due to sub displacement and any other bracing displacement our baffle displacement. t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.
alenv10 Posted January 10, 2014 Author Report Posted January 10, 2014 you lost on that last response, but there is only one bend.. i was thinking double baffle flush mount sub NOTHING DOWN HERE YET OBSIDIAN FTW
alaskanzx5 Posted January 10, 2014 Report Posted January 10, 2014 Figure out sub displacement and do the flush mount with double baffle. Then post new specs for the box and a sketch up of it. It will help people visualize things that could help. t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.
alenv10 Posted January 10, 2014 Author Report Posted January 10, 2014 woofer displacement is .13^ft I am at work and won't be home until 630pm tonight, if anyone wants to design one as well i would appreciate it NOTHING DOWN HERE YET OBSIDIAN FTW
alenv10 Posted January 11, 2014 Author Report Posted January 11, 2014 okay here are the new numbers with the sub displacement, and the box design. everything looks great to me except the space i will have between the sub magnet and the port wall... i will have about 4 inches from back of magnet to port. will that be a huge issue? other than that, its 2.04 cubic ft. 34.72 htz 18.38 in^2 of port area double baffle, flush mounted Does it all look good? NOTHING DOWN HERE YET OBSIDIAN FTW
