well i took the box dementions from pre-made boxes for memphis subs- just a bunch of dimentions written on a chart giving the optimum box volume and tunings for all of their subs. i got them from a friend that works at an audio shop. the box was 3 cubes, ported at 34 htz... the port dementions it asked for was 14.5x1.25x15.... so if that isnt correct dimentoins then i'm not sure what to do..... but the box i BUILT is 3 cubes and has a port demention of 2x13.75x10 (and yes, the slot port is on the same side of the speaker).... so what is that box tuned to? (the box is 3 cubes AFTER port displacement)... if there is any other info u need please let me know, because it's going to help me set my amp's xovers and filters.

it was 14.5x1.25x15, and i switched it to 13.75x2x10

sorry- The box is 3 cubes, and i took the cubic inches of an older 3 cubes boxe's port and basically just switched the #'s around to come up with a new port with the same area of the older one.

ok. i built my boxes (still unsure about the subs), and the port came out looking funny. I'm almost sure, but just to be extra sure, i figured someone could help me out. when i ported my boxes, i took the cubic inches of a different boxe's port (3 cubes at 34 htz) and used the same on my 3 cube box (also at 34 htz) the difference is that it isnt as deep, but longer... even though the dimensions are different, because they both have the same cubic inches of port, it's still tuned to the same freq, correct? thanks

i'm running an elemental designes nine.1... (i've heard) it pushes around 1200 rms @ 1 ohm, and i was feeding about 200 a peice to the pr's... so i'll be using more wattage running the two d3's.... i went ahead and did a little more researching and looked at the d6's and in the same box it would take for one d3 12 i could fit 2 d6 10's... and i looked at www.realmofexcursion.com and a guy hit i think it was like 136 w/ a pair of tens!! and i'm almost sure that's what i was hitting with my 3 12's in my truck which is almost unbelievable (well, comming from some 10's in that small of a box)... So if that's the case then i think i could get away w/ putting 3 10's in my trunk and be King of the streets around here lol... most of the people around where i live stay with kicker, mostly comp vr's... well i'm definitely not a big fan of the vr's and will NEVER run a set, so i'd like to get some more options in mind before i buy.... so If i was to bump up the price range on some speakers to compare to the 3 pr's (around $400 shipped) what would be my options? i'm pretty much limited to only about 6 cu feet max, my trunk openings REALLY small, so aside of building in the trunk, i'll have to put 2 3 cu ft. boxes in seperately... thanks -d

I know I know... This is the 2nd time i've asked this question, but noone seems to read old forums so I figured i'd ask again and see if anyone can help me out.... So has Anyone ever heard the Diamond Audio D3 12's? i'm switching from 3 memphis power reference 12's in a ported box (40 htz) in an extended cab truck to 2 D3 12's in a ported box (34) in a trunk of a grand prix... can anyone give me a heads up as to the loudness difference btw the 2? i'm hoping to get at least just as much sound out of the d3's as the pr's...

P.S. the d3's are now going in the trunk of a car.

Yea, but the d3's are $200 shiped for the pair... that seems really cheap, but that's about what the pr's cost too... So am i really looking at that much of an upgrade? i was running 3 pr 12's ported to 40 htz in an ext. cab truck, and i'll be switching to 2 diamond audio d3's tuned to 34.... is it going to be at least AS loud?

daamn, i figured that.... i just wanted better low-end... but i guess i would have gotten that just because i was switching from a car to a truck... so about 40 would give a lot more spl than a box tuned to 34 huuh... well it's not bad i can just build another one later on and decide which one i like better.... so u think i'd get better output from a box @ 3 cubes tuned to 40?

Less power. Efficieny increases and cone control decreases. You have a greater chance of reaching mechanical limits of the driver in the larger enclosure. <{POST_SNAPBACK}> Correct. I understand that, but is 24 htz a good tune to port the subs at? or will i gain more sound out of a higher tuned box?

right. well, i've read that the diamond audio's are geared more toward sq, so i'd like to get as much spl as possible.... so would it be better to port them a little higher?

the diamond audio d3 12's i'm getting are asking for 2 cubes in a ported enclosure.... well I have some extra room and I made up some plans for a box that's 3 cubes and ported at 34 htz..... is going bigger than the recommended volume actually worse? same thing for the tuning freq..... i don't know what they're SUPPOSED to be tuned at, but i think their response is 25-250... so i thought 34 would be low enough to make 'em pound... what do you think?

in a truck, i used to run 3 memphis pr 12's in a ported box around 40 htz. the subs were awesome, i loved them, but since i can't put all 3 in my new car's truck, i'm looking for a new pair of subs that will give the memphis' a run for their money. i've done some reading on the diamond audio d3's and liked what i've heard so far. a few people said they slammed, but mostly i've heard a lot of compliments on their sq. well it's all good w/ the sq and all, but i'm looking for something that'll straight up S L A M !! will these do the trick in a box ported around 35 htz? and if you have any suggestoins that's cool too... i'm buying off of e bay, so i'd like to keep it around 200 for the pair.

right... yea i figured that'd be the easiest way to go, but it still might be a space issue, so i was thinking about "aiming" the subs upward toward the trunk... would that be a problem? because if not i'd have to put the speakers more towards the middle of the trunk, taking away both access to the spare and the actual trunk itself (by the way, i'm running 3 memphis power reference 12's).
