I fully agree I also can't stand it when I go to a manufacturer's website and can't find enough info to build an acurate enclosure. I will be getting with mark in a bit to build a website when we have all of our information verified and get our graphic designing worked out. We will have as much information availiable including Kipple results and charts. We are lucky to have one of the most talented minds in the industry to help with our designing and manufacturing.

The reading on the TL was found to be unacurate. The sensor was bad and reading high. A new sensor reads about 140 on the dash. The amp however is not a kicker zx750.1 it is a kicker zx500.1 wired at four ohms. I will have another unedited video up soon.

Yes this is the first of many lines to come. I have a licensing agreement with ADI and Dan Wiggins designs the product per my specifications. And no this set up is in a 2.25 cube enclosure tuned to 27 hertz as seen in the video, thrown in the back of a 2007 Toyota Matrix with no modification what-so-ever. It is a hatchback so the numbers are a little higher because so, but it is no where near an extreme vehicle. No I would not expect to see a 150 in a trunk, I will however gaurantee it will be louder on less power than anything else on the market in the same "daily" enclosure set up with equivilant xmax. Don't worry there will be plenty of more videos to come in the near future in diffenet vehicles and enclosure designs so everyone can make their own informed decision on the matter.

The sub is first and foremost a sq sub. Because the sub uses xbl^2 we are able to effectively cut the voice coil in half compared to your typical overhung design sub. Because the voicecoil is cut in half the depth of the magnent can also cut in half saving tons of weight and mounting depth. Also when the voice coil is shorten you lower inductance, and moving mass which helps keep rocking to a minimum. Since we have less rocking we can have a tighter gap which inturn creats a higher flux field. The voicecoil is coupled with the lightweight hybrid reinforced paper cone that is half as thick as a normal paper pulp cone. By making things lightweight and with the use of the splitcoil design, which creates a flatter bl curve than any other motor structure on the market, we can use a very soft suspension. This means the spider does its job of preventing rocking with out hindering the in and out movement. All this equates to an audible and measurable decrease in about 30 percent destortion and a 40 to 60 percent decrease in power need to drive the sub to xmax vs any other sub with an equivilant xmax. In short you will be hard pressed to find a better sounding sub with a 24mm xmax and at its price range.

148db 350-450 watts on the dash. The TL don't lie. XBL^2 is coming back with a vengeance. Imagine what 3 of these on a Sundown 1500 would be like!?

I have the specs posted in my forum area. Your typical t/s figures are located on the left of the photo. Pre-order will start with in the next two weeks. Typical turn around to my door is 60 days. depending on Chinese New Year (everything shut down for two weeks) they will be in the beginning or end of febuary

12's and 15's will be offered, I have the specs listed in my forum section. We are still working on final pricing, however msrp will be around 350, map will be around 300. The pre-order sale will start around 200 with shipping included. The 350 price is a real world msrp. This price will leave enough margin in the product so that not only Pinnacle Acoustics can turn a profit, but also our rep firm, and our dealers. This line was designed to not only compete but rival those of the liking of a JL W6. The product will be packaged just as your popular mainstream products in a full color "gift" style packaging. We have spent over a year and a half on r&d with Dan Wiggins to come up with a line that wiould offer superb sound quaility and reasonable pricing, that would save the consumer money in the long run. As seen on the video, Dan's xbl^2 technology enables us to produce decent numbers from a relative small amount of power. The sub in the video is on a Kicker 750.1 wired at 4 ohms metered by a termlab positioned on the middle of the windshield. So it is really only recieving 300-375 watts rms. Most other competitors would use around 1000 watts rms to reach the 24mm of xmax that we are achieving. Just think of the savings involved when you go with that smaller amp, small power wiring, and possibly no need for an extra battery or a large output alternator. Optimal enclosure size for a flat cuve with a 3db rolloff at 28 hertz is 2.25 tunned to 27 hertz. But you can range anywhere from 1.5 to 3.5 cubes tuned anywhere from 27 to 36 hertz depending on your goal.

pre-order sale will be available soon

Due to time restraints Audibel Customs is closing its doors. Over the past year I have been outsourcing the expertise of Dan Wiggins to create a quality line of high performance subwoofers that can be offered at a very reasonable price point. This dream of mine is soon to become a reality. So however I will no longer offer custom built enclosures I plan in the very near future, that SSA will be the official forum for Pinnacle Acoustics.

Sorry to get off topic, but do you have any pics of the police interceptor swap in your vic? I've been wanting to do a swap in my '90. Or did you get rid of the 86 and buy a 2000?

Go with XS, the Metra batteries have too much Margin in their price.

Right the issue is the application. It just ain't gonna happen

I never use a box calculator first, only use term pro to verify my equations. The equations used are ones by Don Keele. derived from T/S parameters to create the optimal flat esponce ported enclosure using the air compliance and resonate frequency of the subwoofer. They are pretty well known equations. VB=(15)(Vas)(Qts^2.87) F3=.26(Fs)/(Qts^1.4) Fb=.42(Fs)/(Qts^.9) Lv=(((1.463)(10^7)(r^2))/((Fb^2)vbin)))-1.463r golden ratio=(2d)(3d)(5d)

The suspension is hella tight with a VAS of 11.97 liters, so the enclosure would be tiny for a flat responce. Here is what I came up with using algebric equations, and term pro was close as well. enclosure would need to be: 8.12 liters or .28 cubic feet tuning : 53 hertz F3 would be around 56 hertz

I am curious to see how it would sound. Someone post the t/s and I will work up the enclosure.

You need to be comparing the BTL to the XCON. The xcon has twice the excursion that the BL has.

depth between the two is not much. On paper the L7's should only be about 12.5 percent louder than the L5's, there is not a huge difference in xmax between the two. If it was my vehicle I would sell the kicker stuff, and get a Sundown amp with two ICON 10's. It will be as loud as the kickers, cheaper and sound a lot cleaner. As far as the custom work goes anything could be done, depending on the installer and your budget.

You don't hear about xbl mcuh because Dan Wiggins holds the liscence to the product and he only does OEM work now. Kinda like a neo magnet, not many companies use it right? But what most people don't know is neo magnets are used on just about every small application from cell phones to the motors on the active braking on a Toyota Pruis. Mr. Sagat, if you miss Adire, I am working on 12 and 15 that achieves 24 mm of one way linear excursion with only 600 watts that might interest you.

This is watered down example of XBL technology. Normally a motor's flux field field is strongest around the center of the magnent and decreases in strength further away. However XBL uses a little tooling in the motor that widens the flux field. There are several advantages to this, here is just a few. Because the flux field is wider this allows for less magnents on a driver. Instead of having two or three magnets stacked together to widen the flux field, XBL can utalize a smaller amount. This makes the woofer lighter, and less expensive. The flux field is distibuted over a larger area than most, this means the voice coil stays inside the magnetic gap as the cones moves farther out or in, unlike a conventinal motor where the coil would be moving out of the range of the magnetic flux. So being the magnetic field is just as strong at rest as it is at Xmax, a XBL woofer can use up to 40 percent less power to reach xmax than a conventinal driver, because a conventional driver looses that magnetic force as the coil moves away from the magnetic gap. http://www.adireaudio.com/Files/XBL2DetailsPaper.pdf The above is a link that explain it better.

I use pretty much the same concept but I would put the bolts about every 5 or 6 inches apart. Plexi flexes pretty easily. You will be able to see the flex pretty well if you just put bolts only in the cormers. If I don't plan on removing the plexi, I use heavyduty liquid nails as a sealant. I find it bonds to wood better than caulk or silicone. And for the bolts I use a bolt with a flat screwdiver head that is similar in looks to a drywall screhead so I when bevel the hole in the plexi the screw sits flush. I also use a t-nut with a teflon insert like a lock nut.

The carpet will act like polyfill slowing airflow making the enclosure seem larger, which would make tuning higher not lower. With the minumum amout of area the carpet takes up, you will not hear any audible difference. And it will not affect port velocity because the carpet does not enter the port.
