Im ordering it today just a few questions. Its nominal is 1000, how much can i run to it daily if i get it fully loaded. I have a BXI 2010d which is sadly underratted to around 1700 Rms //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif can i run that to it daily or will it freak the **** out?

 
I would say enclosure is going to help with power handling,also if u have the cooling options and send the subwoofer a non clipped signal I would say it could take the power. If the box is on the smaller size it will help. I say try it out and if u start smelling woofer then turn the gain down some lol.

 
you should be fine. set gains right. hifonics amps clip very badly
On this you are correct my friend.. Im hoping for my birthday soon my dad will either buy me a saz 3500d or a new alt.. and ill buy whatever he doesnt buy.. But you think around 1500 rms should be good?? im hoping to be louder than my two chunty *** type r's //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif my box is 7.37 cubes internally tuned to 31 hz i believe i might have to check really quick..

 
The BL line is pretty much a lower power alternative to a BTL or a higher power alternative to the Q series of woofers. This is more of a street jamming type woofer that “fills the gap” if you will between these two series of subs. Keep in mind this is what we recommend, this is NOT what you have to do.

Available options and what they do:

P Chamfer: This is a chamfer on the end of the pole, it helps to bring the air down around inside of the motor and helps cool the coil better. It also helps relieve the pressure underneath the dustcap. We recommend at the bare minimum to get this option if you choose this series of woofers.

Hyper Pole: This is an extended version of the standard P Chamfer. It has 1.250” more pole and chamfer resulting in an increased compression ratio for better cooling.

Cooling: Self explanatory, the cooling channels are machined into the inside of the sub to help cool the coil FAR better. But there are some things that you sacrifice. There is less metal inside of the motor so it is a little weaker. If you are looking for a tone/burp only scenario for SPL we suggest that you do NOT get this option. Stick with only the P chamfer or Hyper Pole. Now if you are looking for a daily sub to beat on and you have less then 2000 watts then this is the option for you. 2000+ watts you need to look into the BTL series

Flatwind: The flatwire coil option simply helps the power handling of the sub. The coil has more surface area to dissipate heat and will take more power then the regular round wire coil that comes in the ‘stock’ version of the sub. If you are looking to do an SPL install we highly recommend that you use choose the flatwound coil option. In testing it is louder then the regular roundwire coil and takes the thermal abuse much better.

SPL: Simply put, if you plan on listening to any type of music you MUST choose the daily option. If it is strictly for a tone only scenario then choose the SPL option. The reason we have these options is the gap tolerances between the two are different. The gap in the SPL woofer is much tighter and FAR less forgiving in comparison to the Daily option. The Daily option simply gives the coil more wiggle room inside of the gap to deal with the non-linearity tendencies that you can get into when you are using a sub in a daily driving scenario. Typically SPL applications deal with 1 note and it does not change, therefore we can make the gap much tighter and get all of the motor strength that we can out of it.

Extreme Lead: Is normally only chosen for high power applications. It adds an extra set of leadwires to the pack and helps in higher current applications. There is no problem in using it for daily, other than it normally isn’t required given the normal power used.

Universal: This option gives you the choice to later chance the impedence of your voice coils. You can change from dual 2’s to dual 1’s and vice versa by reconing them. If you do not choose this option your motor(s) will be optimized per the coil resistance that you have chosen. (Dual 2’s will forever be a dual 2 motor, Dual 1 will forever be a Dual 1 motor).

First off we do not recommend using a sealed box for any of the BL or BTL series of woofers

Enclosures:BL 10 – Ported box we recommend using .5-1.2 cubic feet from 30-37Hz tuning with ~15 square inches of vent. (IMO 33hz tuning daily driving is optimal)

BL 12 – Ported box we recommend using 1.8-2.5 cubic feet @ 30-37Hz (I personally think that a 33hz tuning is optimal, and has the most output and is still the most musical daily driving). Use 12-16 square inches of vent area per cubic foot of volume.

BL 15 – Ported box we recommend using 2.8-4 cubic feet @ 28-37Hz. Again use 12-16 square inches of vent area per cubic foot of volume.

BL 18 – Ported box we recommend using 5-10 cubic feet @ 30-37Hz tuning, you can tune a little higher if you wish but we recommend keeping it close to 33hz for a daily driver. Again the same 12-16 square inches of volume applies per cubic foot of volume.

 
Im about to order this sub as we speak does it matter if its universal or not?? and what about daily or spl option also?
go with the daily option, the spl isnt made to run daily. From experience I had a bl 18" in 7.5 cubes tuned at 35hz off 1500 rms and it slammed it did get a little warm after about 30 minutes at high volume but never hot, as long as you don't clip the sub it should do just fine.

yah, the hifonics amps clip horribly. i had one and my sub would smoke all the time and get hot. my friend has one on a re sx and it smokes all the time and gets hot. now, i have the aq 2200 and the amp nor the sub even get hot after banging for a long time. the 18 should get lower. idk if theyre 12s or 15s. but it should be a very nice setup with the right box. but, change your amp in the future
