1 dd9515 or 2 AQ HDC15s in 6 cubes. What do would be louder?

[shakinghorizons]

Right now i am running a small box for 2 15 cause its all the room i have, it is a six cube box with a common chamber tuned to 37 hz. My numbers as of now running 2 IA40.1's @ 1 ohm on my 2 AQHDC315 aluminum speakers is a 150.7 out of the trunk on the TL sealed up at 41hz legal, but i since i have a small box for 2 AQ's, if i were to reface my box and just do 1 DD9515 with 8kw and with 6 cubes and plenty of port, i forget my dimensions btw. Would it be louder do you think or do you just thinking im doing some crazy talk?//content.invisioncic.com/y282845/emoticons/waycrazy.gif.f4a380c3f94043939fd369defd9e6be2.gif

i dont think the 9515 will take that power daily unless this is for comps then disregard

keep what you got, thats plenty loud out of a trunk!

my 9515g in 5cubes in a trunk wall tuned at 40hz burped 147.7Legal on my massive p3000.1 at .5ohm we clamped it at 3750watts rms...

this was in my monte carlo

my next system will me 2 hdc3 18s in 9cubes on prolly a Stetsom 4k2d or 2 saz-3000ds.. im my mag

What about the 9515g, that can handle that daily easy am i wrong?

get a D2 and run it 4ohm daly and 1ohm for burps, if u insist on doing 8kw.. thats what i did when i had d1's in my 9515g.. it was 2ohm daily (the 3000w rms of my p3000.1) and i burped at .5...

i just dont think 8k daily is good idea

Ok, so let's get passed to wattage. I run probably 4-5k daily I don't do 8-9k except when I hit thr tl, I don't have my amps pegged out max for daily obviously that would be stupid. But ehat my question is will 1 15 do better with the proper sized box or 2 15s crammed with too small of space?

you would be better off doing 1 18 in 6cubes then 1 15. and 3cubes a piece for a single 15 isnt really all that small, but yes it is on the smaller side

6cf is pretty small for two 15's so i'm suprised its toned as low as it is. But two 15 all day long will be louder and handle power way better.

If you are putting up more power dont it like smaller boxes?

 

[abrhino 10+ year member]

i would just keep the 2 15s mang

your 2 aq's are not crammed.. 4cf per is rec. now ssince its a common chamber take you need 20% less airspace. so 20% of 8 is 1.6. you are .4 cf smaller than the rec. just give them more power
