darksoul989 Posted August 1, 2013 Report Share Posted August 1, 2013 Hello, First note I appologize for any and all bad spelling and grammer lol! I am new to ported box building and need major help. For starters I listen to just about anythink as far as music and not much for constant high volume, but i do enjoy a good consistancy of bass. I have gone through 5 subs in past 3yrs. So far 4 had been Alpine Type R's and put in boxes that where recommended from both reviews as well through tuning calculators saying it's a close match. 5th sub was a Memphis Mojo 10d2 bought with a custom box built same day, that lasted me a hold 4 months at normal listening levels before blowing out at random! At this point I measured the box myself and it was 0.10cf to small! I got another Mojo for free as a replacement thanks to the shops mistake and this ones in a Bassworx box, sounds amazing, but at higher volume you can hear reverb from port and tuning not being correct. Using my current Mojo (15-Mojo10d2) I'd like to have a custom box built correctly! I have been messing around with many calculators and having bad luck getting the box shape I want. If someone would please help me I grately appreciate it! I'm wanting a wide box with eather a bottom port or two side ports. I'm not sure if should just use round ports or go for slot to give the hole box better stability. Box idea is for SPL or close to SQL, box roughly (Wide 22''-25'', Tall 13''-15", Depth 13''-15'') and will have a rear glass window with LED in the box. Woofer displacement of 0.14cf (Cone/Mounting Hole 9.43'', Mounting Depth 7.5'', Xmax 0.625, Magnet Diameter 8'', Magnet Height 4") SPL - 1.50cf 45Hz SQL - 2.25cf 35Hz ANY AND ALL HELP IS GREATLY APPRECIATED! Needs this monster sub to last!!! (Notes) Stereo Deck - Pioneer: deh p5100ub Mids/Highs - Pioneer D Series (running off Deck only) Sub Amp - Alpine: MRP M500 Sub - Memphis: 15-MOJO10D2 (10") Sub wired to 4ohm running at 300rms...

Hellbilly429 Posted August 1, 2013 Report Share Posted August 1, 2013 See, that wasn't so bad. I would change the thread name to ported enclosure help for 15" Mojo. Also let us know what you are powering the sub with and what vehicle it is going in. I can give a stab at it for you but there are others who are much better at this game than I am, like Joe X 2018 Honda Civic Sport Hatchback (build in progress) NVX Sound Deadener (Front Doors) Stinger FAST Rings Stock Electrical SSA Evil 6.5's Front Speakers Stock rear speakers MB Quart ONX4.80 speaker amp Rockford Fosgate T-1500bdcp DC Level 4 12" D1 @ 2-ohm Box In Design Stage Stock RadioMy Build Log Link to comment Share on other sites More sharing options...

Hopefully can get something made up, blowing out good subs is getting far to annoying and expensive! Link to comment Share on other sites More sharing options...

Hellbilly429 Posted August 1, 2013 Report Share Posted August 1, 2013 It would be much more feasible with a slot port to do a side port as with slot ports you don't want them to be much more narrow than 2", and it is harder to tune low with a slot port without using 3 common port walls, and to do so across the top or bottom of that small of a box 2" wide is damn near impossible. Aeroport would be easier, and you could just double up the front baffle and add dowels for bracing to rigid up the box. Here is my shot at a slot port with port on the side and sub/port facing same direction 2018 Honda Civic Sport Hatchback (build in progress) NVX Sound Deadener (Front Doors) Stinger FAST Rings Stock Electrical SSA Evil 6.5's Front Speakers Stock rear speakers MB Quart ONX4.80 speaker amp Rockford Fosgate T-1500bdcp DC Level 4 12" D1 @ 2-ohm Box In Design Stage Stock RadioMy Build Log Link to comment Share on other sites More sharing options...
Hellbilly429 Posted August 1, 2013 Report Share Posted August 1, 2013 Ah, I asked cause if it was a hatchback or suv some people benefit from a sub up port back configuration, but for a trunk sub/port 1 direction works good 2018 Honda Civic Sport Hatchback (build in progress) NVX Sound Deadener (Front Doors) Stinger FAST Rings Stock Electrical SSA Evil 6.5's Front Speakers Stock rear speakers MB Quart ONX4.80 speaker amp Rockford Fosgate T-1500bdcp DC Level 4 12" D1 @ 2-ohm Box In Design Stage Stock RadioMy Build Log Link to comment Share on other sites More sharing options...
Hellbilly429 Posted August 1, 2013 Report Share Posted August 1, 2013 As for the glass on the back, unless you use 3/4" plexi glass I would say don't do it 2018 Honda Civic Sport Hatchback (build in progress) NVX Sound Deadener (Front Doors) Stinger FAST Rings Stock Electrical SSA Evil 6.5's Front Speakers Stock rear speakers MB Quart ONX4.80 speaker amp Rockford Fosgate T-1500bdcp DC Level 4 12" D1 @ 2-ohm Box In Design Stage Stock RadioMy Build Log Link to comment Share on other sites More sharing options...
