What airspace? Are you going to be using it for a daily setup? How much power and what kind of music do you like listening to?

i have a db 2000.1 amp and its a daily set up will go to one or two comps just to see what im hitting and im getting the box built so i have no numbers to give him so i was looking for ideas i just want to get the best out of the sub as i can

Well the HDC3's definitely prefer a higher tuning if you want to get the most out of it. I think you should be fine with tuned to 36.

I like 34.

Buck you always like them tuned lower

Proper compression says to go with 41.35Hz, so even 40 would be fine. Yes, they do require higher tuning as kangaroux mentioned.

From my hands on experience(if that counts for anything considering AQ/DD lol) tuning higher with them yield great SPL results and horrible musical performance. However, tuning 30-35 depending on application works amazing for them. The T/S listed on the site are way off and do not look for them to change them or give you more accurate ones as that won't happen.

I know. IMO subs shouldn't play over 55-60 hz. I just think lower tuning sounds better. I have messed with quite a few AQ's in real life and that has been my favorite tuning. Yes they will play low even tuned high, but they don't sound good doing it.

no they do not require high tuning, they require it for break in that is all.

They play flatter and sound better tuned lower to help compensate for their low xmax. I actually have experience with AQ and DD's plenty of it, I maybe ran 20 different boxes for my 12's.

Small chamber, huge port, tune low, that is how dd's and aq's like it.

They best box for them is an abc box how ever

Since when do HDC3's have low xmax?

Depends on which version of the HDC he is talking about. In truth they were not designed for large excursion until this last version which were discussed/designed while I was there.(Not saying I had anything to do with that though...just pointing out that I was there during that time.)

I'm talking the original hd3c's, I forgot they changed them again.

the ones with the dd/soundstream baskets on them.
