No, the program takes into account driver displacement, so the numbers are correct. Only real issue with the program is the fact that port area is based off of Xmax so you dont have a simple way of overriding their sizing/recommendation. Id say youd be fine with just the pole chamfer as well if its only doing 1250W. More, and Id look to the cooling or flatwind to pick up the balance.

Fast beats is debatable as the BL seems pretty good on doubled up stuff as well. Q has more linear excursion and bottom end performance than the BL. But the BL can handle more abuse mechincally due to the beefed up suspension.

bdawson72... you know me and my ratings. Gotta stick to my guns As for the RF or Kicker, both are solid amps and would do well with a pair of BLs. While not as much power as a pair of the other amps, if you can get a really good deal on them, Im sure youd be happy with their performance. The only issue those amps have is the lack of an adjustable subsonic filter. Both are set rather low and at too low of a filter slope as well. Most people simply deal with it, or some add an additional filter like one of the Harrison F Mods or one of their new adjustable F mods. If you are active and have some EQ ability (either a standard multiband EQ or a parametric filter, you can do the same thing). Thanks, Scott

At 7 cuft tuned to 28 Hz (I pushed it a little lower to flattne the response a little more) you will be about 4 dB up on the sealed enclosure. 4+ at 40, 2.5 at 50 and 2 at 60... about even at 70. The ported enclosure will definitely be louder, but itll have a bass hump in the 30-60 range vs a relatively flat and more natural response from sealed. Thanks, Scott

Often in trunk cars sub and port back is the way to go. Im assuming that you can fit a 40" X 22" X22" box through the trunk opening??? How much clearance and space top to bottom, front to back, and side to side does this give you? I have seen plenty of people that max out their trunk space and the box fits so tight under the rear deck that they trap a good portion of the sound in the trunk... trunk rattles like crazy and would be very loud for whatever kidnapped person was stuck in it... but not so much in the cabin. Plenty of space for a single BL18 though. Thanks, Scott

Yes, please send it on in and we can see what coils we can fit in there. I do love their "3" peak to peak excursion"... exceedingly wishfull thinking given that it is a 10" basket with what appears to be a 1/2" spacer for the dual spiders. I have mentioned before how the 10" subs have geometry issues, and they simply made it worse by getting rid of 1/2" of rearward clearance with the spacer (yes spaced spiders are a good thing and help with stability, but on this basket, it comes at the expensive of rearward clearance and excursion as well... maybe 2" of p-p).

Thanks, Scott

Not sure if I can recone that one or not. Like most things... if its standard US sized coil IDs, then I definitely can. Looks like gravity got the better of that basket

Yes it is... thanks...lol

Id stay away from a pair of Qs if you are going to have that much power. The BLs with cooling and flatwind coils would definitely be the way to go. They will take the power much better. Thanks, Scott

lol... Im not a fan of humidity. We have actually had some with the little bit of rain we have had over the past week or two. Ill take 115 with no humidity over 80 with 100% any day. Let me know when your in town next time.

I absolutely love IB HT setups. But I can see where you would have issue with the vibrations in the drop ceiling. But... even with the BFD you still have a low qts setup with the Assassins. I would look to find a driver with a higher qts of .55-.65 for a solid IB setup. You will have the same issues with using the Brahmas for IB subs as well. Their Qts is too low to be a great candidate even though they have plenty of linear excursion. Pics of the sealed box?

Yes, in most cases the pair of Q15s would be louder than the single BTL18 with that amount of power. You definitely have the space to do justice to either setup. But... with 1500-1700w a pair of SSDs might fit the bill better as well and save you some $$$ at the same time.

Its hard for me to keep the customer names and forum names straight half the time...lol Just keep beating on the sub. It wont mind the spider tears. We normally use a 5 spider combination on the BTLs now. Seems to provide the best durability. Some SPL apps have even more. Having wear, cracks, tears, or anything in 1 spider wont amount to much in the grand scheme of things. Just keep punishing it Things sound OK so far?

Glad it arrived in good shape. Please let us know how it sounds/works when you get things going. As for the felt, we use them on all of the daily subs. SPL is optional.

Got them squared away... Hows Wasco?

lol... that is exactly what I drive Im a big fan of sealed for clean/SQ oriented applications. But I have noticed that most people tend to favor the bloated bottom end of a ported enclosure. If output is a concern, ported will get you there with a larger box. Sealed will have a more natural response curve when cabin gain is factored in and will still be loud overall... just not as "fat" around tuning like a ported enclosure.

Should make for a solid setup with that amp. Pole chamfer should be enough with that power. Thanks, Scott

Looking good! I got 8 of these motor thingys machined and assembled. Gonna start all the soft parts and fumes tomorrow

What kind of 4 door is it and how much height do you have to work with?

How much power do you have to work with? Ill see if I can come up with anything that might work...

ANeonRider... Ive got a $5 that Ill put down on that bet lol... Im not much of a gambler The Q has aluminum round wire coils. Not copper or flat. While flat might help a little more with power, other things need to be worked on to handle the extra power as well... hence the BP option. Copper simply would weigh far too much to be useful. Not much of a difference with the specs for the flatwind... copper allows things to drop deeper and does have different specs. But as mentioned above, we go more by what we have tested over the years and know to work well vs what the programs tell you to use. Vehicles transfer function will dominate the pretty response curves from the box programs

Thanks for the review. Please keep us posted as to how it does long term... itll break in some over time and the sound will slightly change. Most say it drops a little deeper after break in.

Im assuming that is 3.75 net after port and driver displacement (if thats not the case, change all the 15 recommendations to 12") The BL would be a little bit flatter overall with probably closer to a 50/50 split. The Q15 would need to be tuned a little lower to try and knock out some of the 40-50Hz hump it would have (BL has a flatter response in that sized enclosure, although not as much overall linearity)

Glad they are working well for you. Solid score. How do they sound for music?
