Audioque HDC 15"s.... holy shit

:fyi:So I was sick of not having any bass so I threw one of my new HDCs into a ported box I have laying around. I had also picked up a JBL BP1200.1 recently and I wanted to see if it worked so I threw it together in about an hour. I wasn't expecting much considering the box is tuned to 32HZ and it would only see about 1200 watts at 2 ohm. Well... these things are insane. This 1 15" is way louder and lower than any subs I have tried. My moonroof is flapping so bad I have to crack it to play full tilt. Sounds much better than my old DD 3515 and it had an Orion 2500d or an IA 20.1 on it. I can't wait to see what happens when I put in the other one and my 40.1:crazy: Things are falling off my interior and a few years worth of bugs came out of my domelights while playing Gorilla Zoe. THis is also the first system in my new MDX.

The only thing I have noticed is with tuning your box this low it will not play much above 50HZ. If you have a ton of midbas up front this won't be an issue, otherwise you may notice some things missing from the music.

Cliffs: threw a temp setup w/ HDC 15" in my car w/ 1200 watts. Extremely:veryhapp:

Be very careful with that low tuning...

DJ recommends tuning way above that.

I still gotta pick one of these up one day to play around with.

these have the aluminum coils too so I was worried about the high fs but it plays so low I don't think it should deter anyone from getting these

I am in the process of building a box for a pair of these that will be tuned higher. It almost sounds exaggerated on the low end tuned this low. I think tuning higher will blend better with my front stage anyway.

what are you going for with tuning? 38hz?

Are you saying that in a box tuned to 38-40 that they will still play the low low notes?

If so, I'd love to have 1 please, sir.

tuning low doesn't decrease bandwidth, the woofer wasn't designed to be tuned that low thats why its lacking... try a smaller box tuned to about 36... low Q high FS usualy means 4+ cubes tuned to 40+ but don't be scared to experment with it a bit.. 3.75 tuned to 36 should do nicely... subs just aren't very musical tuned that high.

its in 3.5 cubes right now at 32hz with 87 square inches of port.... the new box will be 9 cubes tuned to about 35-36 with 150 square inches of port for the pair

They can be very musical tuned at 38-40Hz. Either your front stage can't keep up/blend properly or the box was on the small side which made it "peaky" sounding.
