BL Enlcosure Recommendations
BL Series: Available options and what they do: 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. 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 fart/burp only scenario for SPL we suggest that you do NOT get this option. Stick with only the P chamfer. 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. This option will also make the sub tend to be more prone to ‘peaking’. 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. Daily or 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 fart/burp 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 tendancys 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: ONLY choose this option if you plan to use the woofer for SPL ONLY applications. This option tends to yield really bad tinsel slap and rubs holes in the spiders (especially on the 10’s and 12’s) it is not intended on using in a daily driving scenario. 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). Enclosures: First off we do not recommend using a sealed box for any of the BL or BTL series of woofers BL 10 – Ported box we recommend using .5-1.2 cubic feet from 30-37Hz tuning with ~15 square inches of vent. (IMO 32hz 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 32hz 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 32hz for a daily driver. Again the same 12-16 square inches of volume applies per cubic foot of volume. Pictures and cut sheets for some enclosures coming soon.

BTL Enclosure Recommendations
The BTL line is our flagship woofer. Its whole design is based on and focused on being able to throw tons of power to something in a Bass Race or �Street Jam� situation. Options Available are as follows: 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. 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 fart/burp only scenario for SPL we suggest that you do NOT get this option. Stick with only the P chamfer. Now if you are looking for a daily sub to beat on and you have 2000+ watts the BTL series is for you. Flatwind: The flatwire coil option is standard in the BTL. HiXmCoil: This coil is simply much longer than the normal dual 1ohm or dual 2ohm flatwire coils and allows for more xmax. If you are using this in a daily scenario we suggest that you choose this option, especially in the 15 and 18 inch models. Inner Heat Sink: Its a machined aluminum ring in the gap that lowers the voicecoils inductance (allowing it to play up higher and have a little better overall transient response). It also reduces the volume inside the magnet gap of the motor increasing air speed with the cooling as well as allowing the coil to kick off heat to a more receptive thermal mass rather than magnets. Daily or 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 fart/burp 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 tendancys 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. 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). Enclosures: BTL 12 � Ported box we recommend using 1.75-2.5 cubic feet @ 30-35Hz (I personally think that a 32hz 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. BTL 15 � Ported box we recommend using 3-5 cubic feet @ 30-35Hz. Again use 12-16 square inches of vent area per cubic foot of volume. BTL 18 � Ported box we recommend using 5-8 cubic feet @ 30-35Hz tuning, you can tune a little higher if you wish but we recommend keeping it close to 32hz for a daily driver. Again the same 12-16 square inches of area applies per cubic foot of volume. Pictures and cut sheets for some enclosures coming soon.

more mods are being made to the forum
Yeah that was annoying as hell...cant handle a big GOOGLE add in the middle of a post.

15" Q Dustcap Getting Very Warm
Clipping? Yeah it can hurt it...it can burn the coil . Drop the substage output on the headunit down to 0 and set the amp accordingly, i honestly think your clipping it.

15" Q Dustcap Getting Very Warm
might be clippin it a bit

BTL or BL help asap
No If you are running 1 amp per sub and you need a final 1ohm load to each amp, you need to get dual 2ohm coils and wire in parallel. (+ to +; - to -)

Scott or Nick Please Read.
As long as you stick to our enclosure recommendations you are in good shape. Use Winisd to determine the length to the given port area that you have chosen to. As far as graphing to look for any sort of response curve it's pretty much useless..and inaccurate in a car environment. Thanks -Nick

Tensil length on recone?
No problem man

Lost information
http://www.soundsolutionsaudio.com/forum/i...?showtopic=7104 Thanks man! Hopefully i'll get everything as far as box info, suggestions, options etc etc etc up by Saturday or Sunday.

Tensil length on recone?
ummmmm...they might be ok I'm not sure how long the coil is though... see if the cone in the forward position will pull on them or not
-
Question? Box tuning vs different subs
no the tuning will be the same...possibly a smidge higher or lower due to different woofer displacements, but so little i doubt you'd hear a difference

Welcome to the IHoP
No chit buddy I cant touch anything until i get this exam and 1 hour presentation out of the way tomorrow, then i am making my way to the grocery store...cookin' kabob's for the girls & company, and proceeding to get fudgeED up. This has been a week from hell, i'm not gonna lie.

Lost information
Ok guys, looks like we lost a lot of the information we had, I will work and get all of the enclosure information back up, explaining the options and everything else that we previously had. I apologize for any inconvience this may cause you. Feel free to post questions and register for the forum if your account has been lost. Once again i'm sorry this happened, but it did and we need to build this place back up to what it once was! Thanks! -Nick

Welcome to the IHoP
Well, at least we still have a board .

whats the benefit of the flatwound coil?
Neil hit he nail on the head. -Nick

My 15" Q's
Gained 6dB of output at 29Hz when i opened the port up in the thunderbird 80 more square inches ...length only changed 6"...
-
My 15" Q's
Not with only 70sq in of port with a pair of 15's in 8 cubes... It can't breathe...it's choking it and throwing tuning off.

Welcome
Thanks for the welcome guys - Scott will be registered and here sometime tonight. Special thanks for Aaron letting us use SSA for our official forum. I've got a ton of stuff to do right now, but i'm sure scott will come on here later on tonight and we'll probably do a little bit of history and background on everything. -Nick
