1000w 12" driver that gets low?

Have A b&w asw cdm missing the driver and looking for something to put in it. I have a idmax 10" I can put in with a adaptor ring but wondering what my options are.

If the original sub was ported (and i think it was), then any driver going in that box will be a crap shoot. It is best to stick with the original driver... Otherwise the sound will most likely be way off.

If it's not a BIG screen, it's not a theater...

19.5 kb limit for attaching pdf's...WTF? ;-)


spec sheet in here: http://www.bwgroupsupport.com/manuals/bw-archive


1000 watt small sealed enclosure.


the trick would be to know what impedance the amplifier is set up for.


I couldn't find the impedance of the original driver. an email to the company/tech support should bring that up.


then you want to make sure the driver that you get will fit in the cutout.


there are a whole crap ton of 12" drivers that would be good in a small sealed enclosure like that.


with only 1000 watts, not too much xmax is necessary.

Listen. It's All Good.

this is the sub if anyone needs the info.
http://www.woofersetc.com/p-2030-idm...subwoofer.aspx

the cdm is a sealed enclosure and i believe it was a 4ohm driver when i did my research awhile back but will try to verify.

Also i was thinking since i have two idmax 10" subs, put those in boxes for the higher bass frequence and put a 12" in the b&w that can go low. I looked at re xxx 12" but it will want to much power.

Or you can contact B&W directly via their super secret squirrel support portal and get an exact replacement:
http://bwgroupsupport.com

If you have warranty they will probably do it for free, otherwise it will cost you some coin.

I run my TC-1000 with a exp3000 (about~ 1500W true RMS) in a sealed box about that size, works great. Is that a 4ohm amp in the B&W sub?

if it is a 4 ohm, the swr12d2 (wired in series for 4 ohms) and the tcsounds epic 12 (also dual 2 ohm coils, so wire in series for 4 ohms) both have around 20mm or so xmax. the swr street price is about $150 or so and the epic 12 is just under $200.

Listen. It's All Good.

Thanks for the recommendations! How low are you guys getting with these? And with a budget of $400 would there be better options?

there really isn't "how low"


if you have the power and eq, you can shape the response to whatever you like.


the spl will be limited when the driver runs out of excursion (xmax) or the amp runs out of power.


both those drivers have about 20 mm of xmax.


that is good for about 100db at 20hz, more or less.

Listen. It's All Good.

Ugh. I meant to say Epic. That wouldn't normally be embarrassing except I came up with the name, lol.

The tc1000 and epic are more similar than not and perform about the same.

"Ok I found some info on the idmax and found out they have decent output till about 15hz"


they have about 25mm xmax so about 2db more spl than the other 2 drivers mentioned.


saying a driver has output till 15hz is meaningless. every driver has output at 15hz. the question is how loud. in the low frequencies excursion limits spl, so just look at excursion if you want to know how low a driver can play.

Listen. It's All Good.

here are the three drivers, each in 1.5 cubic feet, sealed, 1000 watts power.


that is without room gain and with no eq applied.


with eq, the responses can be made more flat. room gain will help with that too.

no problem.


those are the tcsounds epic 12", the alpine swr12, and the idmax.


there is only about 1.25 cubic feet of volume in there after the driver, so with 1000 watts, no need for more than about 20mm of excursion or so.


i'd probably go with the epic 12".

Listen. It's All Good.

Would it not be better to use the idmax since it is a little louder and I already have it?

Either would be fine, the biggest question mark is what the amp can do,and what filters are designed into it. You may have a subsonic on it that rolls everything off at 20hz anyway. I would fist be concerned about matching or besting the old drivers sensitivity because if even if you have a capable driver, you still need the power behind it. I think any of the 3 or 4 mentioned here are great, also Dayton brand has some great choices for a solid price.

Also make sure the driver mounting holes match up. I think at least the tc sounds mount diam. are in the pdf spec sheet. I dont know about the others

ok so the asw wont fit where i need it to so i am going to move it to the real and ut a idmax 12 in it (to keep all the drivers the same).
i will put each idmax 10 in 1.3 cubic sq ft of space and run a total of 4 for my front stage (purchase 2 more).
here are pics of the front stage layout to help you guys understand my situation. Also put a pic of a car sub box to help get a visual of what i want to do.

one other option i was thinking of is 2idmax 10s for 50hz down and 2 id10s for up till 250hz.

let me know what you guys think
