Looking to buy a raw 12" sub for a diy project. I have a 1000 watt speakercraft sub amplifier and i would like to build a sub enclosure for a new 12" sub but not sure what is the best sounding for hometheater use. Any recommendations on which 12" driver i should look for?

"Best sounding" is of course totally subjective. What are your design goals? What is your budget? What sort of alignment do you want to build?

Any recommendations on which 12" driver i should look for? take a look at the tc sounds driver. Tc sounds drivers is what svs uses sent from my phone. sorry for the short response

A 12" sub that will fit in about a 3' cu enclosure that goes low not interested in the upper bass frequencies, the crossover is set at 40hz. I don't want to really pay much over $500.00 just for the driver. Thanks

Anything lower and you run the risk of losing information in the lfe track. sent from my phone. sorry for the short response

I have multiple subs and just want one to do the very low frequencies only and let the other subs do the rest. I am looking at vented enclosure.

OK, a couple of suggestions. First off, if you are set on using a 12" driver a ScanSpeak 30W has a nice low fs of 17Hz and would be a great performer in 3 cuft vented @ 24Hz. But my second suggestion is to consider using a largr driver. a 15" or even an 18" and get more output in the first octave. Or if you REALLY want to get that first octave, consider installing an IB system if you own your home...

My subs get that low, i just want more low end. I would rather feel it than hear it mostly! My 1000 watt monster godfather sub sounds very good and goes low but has plenty of the other bass frequencies even with the crossover set low. My other sub is a 12" svs pc plus cylinder and also sounds very good bit i am still left wanting more lower end, feeling more and hearing less is good to me. I love for example when watching star wars i can feel the vibration of the ships engines but cant hear them as much. It feels cool and is damn impressive to show off when i don't feel it at most if not all my other friends homes whom also have systems. Now i am left wanting more shake and less boom so to say.

Adding another subwoofer, especially a 12" driver in a 3 cuft enclosure, is not likely to get you there. What I suspect you need more than anything is to find a better location for your existing system(s) and look into proper room treatments, especially if the space is large. I have no idea what a "Godfather sub" is (sounds like a sandwich from a pizza chain) but an SVS PC12 Plus can get down to below 40Hz in room with ease. Describe your room setup. And is building an IB installation possible?

Monster eleganza godfather 1000 watt sub. Retailed for $5000.00. Looks beautyfull and does sound very good to me, uses a auria 12" driver i believe. I have corner bass traps in all 4 corners and have some pannels in back of my main speakers and pannels where the subs are as well all carpeted floors too. I can do a ib system just need to know what driver i should go with for the lowest possible frequencies.

Like I said, you are not going to improve on what you already have simply by adding another 12" driver. Period. You need to improve the positioning of the subwoofers you alreay have. Unless you are listening in a stadium you should already be getting plenty of sub bass from your system. If you are seriously interested in building an IB system, I can help you or you can go visit the experts at The Cult.

You are chasing the wrong frequency if you want to feel that punch from your subs. The subsonics can be felt but in most movies the 60 to 120 gives you that rumble that shakes the pants leg. What do you have the subs connected to sent from my phone. sorry for the short response

DYohn is right, adding more drivers won't help. Maybe you need to feel the low frequencies rather than hear them. I would recommend some sort of tactile transducer for that added touch. There are a few to choose from (Clark, Buttkicker etc..). I have Buttkickers (fed with an 1100W amp!) installed in my riser. Even with 3 seats on top of it, the low-end rumble can be felt nicely. For me, that completes the whole experience.

Subs are connected to my antimode 8033c which is connected to my umc-1. I don't want any boomy bass. I built a sub enclosure with a older svs sub after i replaced it with a upgraded driver from svs but i get a rattle sound from the old driver at certain frequencies which is anoying but it don't do it with music! I no longer use that sub and enclosure because of that and was hoping to just find a driver to put in it's place so i can use my 1000 watt speakercraft sub amp again. My monster eleganza sub already has it's own 1000 watt amp and the svs pc plus has it's own 525 watt amp. I want to use my speakercraft 1000 watter again with a good sub that will hit as low as possible.

I havn't thought about buttkickers do they work that well how many do i need for that 1000 watt amp i have? I don't know how the butkickers work my 1000 watt amp isn't too much for them?

First, don't worry about the power of the amplifier. That is only a small portion of how a subwoofer system works, and not even the most important one. Secondly, like I said before, depending on the size of your room I suspect all you need is better subwoofer positioning. And third, have you tried NOT using the Anti-Mode device? It is designed to create a pre-programmed output curve, and maybe it's simply not a curve you like...?

IMO, like pretty much everyone has said, adding a 12" sub is a waste of time and money. If there is any way you can build a box, you could re-use you amp and make a proper enclosure for a 15"-18" driver and get what you are looking for. $500 would get you a very nice driver and all the supplies for the box. DIY is not for everyone but it's a great option that will put anything else you are going to do, to shame.
