Anyone have some experience with DD1512a & 515b

[RooTxBeeR]

i had buiilt a box for 2 10s tuned to 32hz and it got down to about 24hz with no problem.....

it was an L ported type of box...and i loved them

Oh dayum, what woofer where those 10's?

why do you want them to hit that low? even though DD subs get down. that is still very low and risk damage unless you tune your boxes low. but with DDs port needs that is very hard to tune low. and the DC 2k may be pushing it for those 2 1500 12s. box rise may be your friend. dont wire to .5. if you wire to 1 ohm you should be fine

I want to tune the 515 that low, or either the IVX-15, I want to be able to get down that low, so that I can see if I really like it or not. I can hit down to about 30-31Hz on what I have now, and I really like how low end feels. I just want to get a feel for how I will like it to make a final decision on my future end build.

Also I would be wiring to 1 ohm, don't want to waste money on eletrical to support .5. And as far as tuning, If I get the IVX-15, 2.5Cu ft box 29Hz tuned 14.9cuft per foot. The Fs on those is also a lot lower than the 515 so I would at most tune the 515 30Hz sinze that is it's Fs and will tuning there will atleast let me dip into the 20's. Hopefully with a good box and good DD product if I go that route, I just might be able to get down to 23-24 where I want to play around.

you should be ok if you tune that low. goodluck man!

Thanks for the input!

what about aq woofers?

I looked at them, the SD2.5 seems nice. I am trying to get a 300-400 watt rms woofer and over power bit a bit. Along with that, I am really looking for woofer this lower Fs's so I can take advantage of being able to play low without a problem.
