Hello everyone, Im looking for some input on new woofers.

 

Looking to do two 12's in 6.5 cubes, ported to 29 hrz.(havnt designed yet) I am stuck between FI Q's and BL's

 

I understand that its not entirely fair to compare specs of subs as there are many variables involved, but how does the BL's motor compare to the Q's? The Q having 28mm of Xmax and the BL having 19mm xmax. Is the BL's motor just much more powerfull?

 

What are the real world diffrences and which one is better for my application?

 

Amp is: 4,000 watts rms(1ohm). they will be wired down to one ohm

with that power you might want to look at xcons or zcons.  The BL would do alright though.

Either is fine for that amp of that power just set the gain right.

he wants to run 6.5 cubes..

A fully loaded BL would put up with the power better than a fully loaded Q?  why?

 

how do their motors compare.

Yea I know he doesn't need to run that big of a box but setting the gain right and listening for stress he should do fine if he does it right.

I do agree on some xcons or Zcons tho.

With that large of a box you are going to end up shredding the soft parts on that amount of power.

well i wanted to stay at 15's but it seemed like there wasnt room.

 

I dont need to do 6 and a half cubes, but I cold if I needed to.

 

How about 5.5 cubes with a huge port.

Why do you want such a large box? 

5 and a half is .25 cubes over the recomended size. I could go to five cubes and be within suggested size.

look into xcons

 

power rating is legit and they sound great. 

 

The BL is more spl based but still a great sub for daily driving.  Their cooling options takes the power handling to 2k at most, but they still rate them at 1500. 

 

The Q is a solid 1500 rms woofer that focus' more on SQ and maintaining linearity at high excursion.  With your power, you could go with the Q, but I would suggest the BL over the Qs for your application. 

 

I would use about 5 cubes @ 32 for the BLs.  Wouldn't tune much lower than that.
