how many cubes does 1 12 displace? would a box thats 2.15 cubes be to big for ported before the sub is put in there?

I'm lookin for 4 type r 12's.....lmk

ok i found out 1 12 displaces .07 so does the box have to be 2 cubes after displacement or 2 cubes before displacement making it 1.93 cubes with sub displacement. this is for ported of course. also what is the recommend freq for these subs. 35?

2 cubes after displacement and they like to peak in the 40's. meter if you can cause i had 4 peaking at 50 hertz a few months ago and now they peak at 43 in my SUV and my friend has a 15" in his truck and it peaks around 46 I think. You can also try to put some blocks in the box to see if the type r likes a smaller box because i've heard of people having a 12 in a box as small as 1.25 cubes.

i believe its more about the vehicle as to where the subs peak at, subs dont necessarily "like" to peak anywhere but where the vehicle itself peaks at. (which in most cases is between high 30's to low 50's.

i understand that. my team has tried type r's in a extended cab truck and a SUV. IMO i think type r's like to peak somewhere between low 40's and at the highest 50 hertz. I have never seen a type r perform good tuned below 40 and the highest i've seen one tuned is at 50 hertz in my explorer a few months ago. For strictly SPL a type r is loudest in the mid 40's. It does depend on what type of vehicle your putting it in to and I agree the it's where the vehicle peaks but I still think that no matter what vehicle you put in it it will stay in the 40's. I would tune to 44 hertz for your best bet but if you can get some time in on the termlab then fine tune it and get a few tenths or maybe another db out of it and then put some bricks in the box to see what size your type r likes. It's just my opinion but my team has been experimenting with type r's for a few years now.

does anyone know how many whats these subs can actually take. they say 500 watt rms but as far as im concerned people are pushing over 1000 watts on these subs. my friend says these subs are next to impossible to blow so im thinking about getting a better amp. would this cause any damage to these subs at all?

If you don't know what you're doing you will blow them.

What's up guys? I'd like some recommendations for a single 12' 1242D w/ 800 wrms. I've already made a 2.6 cu. ft. enclosure (after all displacement) with a pair of 2 in. wide aero ports at 31.5 hz (NO PORT NOISE), but would like to know the best tuning for it? I'm looking for that SQ/SPL balance without sacrificing the low bass. And I know a lot of people say 30-35 hz, but they never say why. I'd like more specifics. I listen to 99% alternative, rock and metal. Thanks folks. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

bringin this back, sooo i have had 2 original 2 ohm dvc 12" type-r in a 1 cubic foot per sub sealed box runnin on an autotek xs550.2 at 1ohm( notorious for makin over 700 rms) for 5-6 years now and have been droolin over the up grades for years but have really been quite happy. welllll the 1223 2010 models came out and i couldnt pass them up plannin on runnin around 600-800rms each in a small ported box maybe 1.3 cubes per(i have a trunk id like to kinda use) tuned to 32hz. my question is with this small of a ported box should i stick with sealed i listen to just about everythin but keep SQ my priority. thoughts?
