AQ HDC4-15 or DC XL-15

Just making sure as I've seen more then one person get bit by measuring inside the trunk, never thinking about the actual opening and what will fit into there.

Off 1500 a copper HDC3 would do well in 4.5cubes if you can fit that...

Ya, we made my friends box and it would fit in there if you could get it in there. I would make sure that didn't happen to me

This is sort of off topic of the thread, but what do you guys think of the FI BL 15 with all the cooling and junk on it? It costs less than either and is a lot easier to get a hold of than the DC XL. Less power handling, but it's cheaper...

That's a downgrade from all the subs listed so far

I had a hdc3 copper coil and 4 cubes is on the big side they sound great in about 3.75 tuned to 35..

If you can't get a dc just grab the hdc4..

The bl with the cooling and flat would coil should easily handle 2kw..

4 cubes isnt on the big side for an hdc3 15.

Yes, I know. Although, the price is also a downgrade though. Plus I would probably only get around a 1500 watt amp, so what the point of a sub that takes around 2500?

If you arent going to ever upgrade amps then ya, it kinda would be pointless to spend more on something you cant properly power and never will.

Exactly. Do you think that the FI BL 15 would be a pretty good quality woofer though?

off 1500 copper HDC3 and 4.25-4.5cubes net. I've built a ton of those set ups....

What you tuning to in 4.5?

For daily they just don't have the linear excursion to sound good..

I've tried 4.5 4 3.5 3.25 tuned from 29 to 38..

Larger boxes are peaky and sound pretty bad but they slam..

Guess I listen to music now instead of strictly output..

Btw I had 60in^2 of port area might have been alittle to much because it was peaky..

If ya want a good sounding street beater I love the havocs and ssa xcons over the hdc

If you want output the hdc alum coil is a beast for the money..

4.25 tuned to 36 you should be able to do mid 140s..

I usually tune to 38Hz since I don't play much rap stuff or real low stuff. Lately guys have been choosing 35Hz and that seems to work well for the lower stuff they play.

4.25 has been the sweet spot for me, boxes and walls. Musical enough to play anything and put up good numbers. 16-18^2 port area per cube...

yea just not the bandwidth i like.. i listen to rap. rock, and techno its tuff to get the best of all worlds having a flat FR from 26-about 70 and having the output is challenging..

got a prototype im working on using atomic apx motor slightly modified..

the real trick to it is having enough mass to get low but not so much you introduce distortion trough spider packs causing non linear stroke while having enough excursion to be capable of staying linear and still having enough mechanical dampening to avoid any overhang ported enclosures are associated with("tight" sound) along with good cooling and minimizing back emf alll while being able to take abuse.. most times its just not possible without a sacrifice but thats where the customer installer and engineer need to be on the same page.. no one woofer is ideal for every application..
