I will be handling order fulfillment on these, so you can contact me be email or PM for ordering.

I have had a couple questions regarding some of the subwoofer options. The Stereo Integrity BM-MKIII is one of the best subwoofers to have been manufacturered in recent years. It just so happens to also work in a very small enclosure and it was possible to make it fit in the 928. Unfortunately, it was so popular that it has since sold out, and a new production run is not slated until summer, so the design can be further enhanced with a reinforced carrier and copper motor components. I was able to purchase several of these subwoofers from the last batch, and have been saving them for 928 owners. I am selling them at the original list price, but they must also be purchased with a SharkWoofer assembly, just to keep other car audio enthusiasts from buying them for a different project. I will be getting the new drivers as soon as they are available, and will post an update when they are available. Information on this subwoofer may be found on Stereo Integrity's website: http://stereointegrity.com

For those who would like to use a more modestly priced subwoofer, or just dont need all the performance a 12" driver can offer - the enclosure does accommodate many 10" subwoofers. Dayton makes a 10" driver which works well in the enclosure, the NS270-44: http://www.parts-express.com/pe/show...4&FTR=ns270-44 I can offer a pre-machined adapter for this driver. Alternatively, a blank disc, ready for you to cut for a custom sub application is available. The sealed enclosure volume is approximately 0.60cubic feet, so please use this figure when determining if the enclosure is appropriate for your driver. The only other limiting dimensions are the 314mm opening in the enclosure and the 120mm available mounting depth. If you need a quick volume calculator to check and see if your sub will work, here is a link to the on-line version of WinISD: http://www.linearteam.dk/default.aspx?pageid=newdriver

One thing not mentioned in original post, is that it is also advised that enclosure be loosely stuffed with acoustical stuffing, which also will need to be provided by the customer (polyfill or fiberglass insulation will also work in a pinch).

Thanks
Hans

To answer another question that I have been receiving, I have had very good luck in the past ordering the XR-1S and XR-5S from the seller dis_sound on ebay. Your mileage may very, but all my previous orders from this seller have been excellent, and you are not likely to find a better price. Because I dont know the seller personally, I am hesitant to give it an official endorsement, but it has worked out well for me in the past. This seller normally has the XR-1S for under $220 and the XR-5S for under $340.

Thanks,
Hans

finally!

Trying to locate kenwood amplifiers which fit, cannot locate any called "Kenwood Reference", do you mean the Excelion series?

Never mind, just none on ebay... :P

As an FYI to the others here, the Kenwood amplifier in Hans set ups is the Excelion XR-5S, pretty reasonably priced at around $300 or so...

What could be used in between this enclosure and the wheel well body..except where the batt tray is...to make it as "solid" as possible to eliminate the booming of the wheel well enclosure itself?

In my mind..I see a thinnish reverberating enclosure, within another metal enclosure (the well)..and some unfriendly results from that.


Note..this is NOT a complaint, just seeing in my amateur mind..a secondary challenge that may need some thinking about.

Bloody Brilliant!!!!

You are the master!

finally!

One to two layers of dynamat should solve that...

The fiberglass enclosure is a very rigid part. It is made from a 3-piece mold, which allows the use of a chopper gun (finish and assembly done with wet hand layup). Now that the mold is done, the actual parts are being made by a professional fiberglass shop using quality production resins and glass (they use the same materials at the shop for boat hulls, car bodies, truck cabs... etc). Also, the design with all the curves makes for a mechanically strong part. In short, there isnt a lot of flex in the sealed enclosure.

Vibration may be an issue for some, and others it wont be. Some additional treatments to the area, or to the enclosure itself may be necessary - it will depend on a number of factors. Using a liquid deadener in the box, such as Cascade or SecondSkin would certainly help control vibrations, but it is not necessary for all installations. Similarly, the addition of some simple foam gasket tape either on the mounting board or around the perimeter of the well will also help decouple the assembly from the chassis.

The SharkWoofer is a kit, where most of the hard work has been taken care of, but it still does require and will benefit from personalization to your own particular project.

I do encourage that customers post feedback on how they improve and modify their kits, it is possible that I may add further options to include these procedures as the information base grows.

Thanks,

FG is rigid..but it would take a LOT of FG to be as resonant resistant as 3/4" M/HDF.


But..if it is made LIGHT and rigid not using mat, then the box would 'sing' at a freq higher than the sub...a mat based box would have a lower resonance.


I love second skin stuff.

finally!

WOOT! Order placed! THANKS HANS!

how much is shipping to Germany?

hans14914

I could ship it via USPS to keep the costs relatively low. If you want an exact shipping quote, send me a PM with your address, and what components you would want so I can calculate the approximate weight.

Thanks

On second thought, I think I'll hold. Forgot about the carputer you guys are working on. I think I'd rather reserve the funds for that.

hans14914

If you change your mind in the future, they will be available. I own the mold and CNC files so anytime one is need in the future, I can run them off in even a single quantity with a projected lead time of about 7 business days.

you are a credit to the forum.





Thankyou.

I love the car as well.

BUT I do not deserve to be the surrogate parent of the 928............as you.

The first batch of these has been built, and are on the way out the door. I have another 4 fiberglass enclosures do in tomorrow, and should have the opportunity to cut the mounting plates and adapters over the weekend.

All of the SI BM MKIII drivers have been sold at this time. When/if I can get more, I will post. It is likely going to be August before the new MKIIII drivers arrive.

To those who have already placed orders, thanks for the support. It is greatly appreciated. Also, my apologies for the late ship date, I have been under the weather the past week or so, but making up for lost time with a vengeance this week.

Here are some pictures of a couple going out from the first batch. You will note that one is the 90+ version modified for easier passage of the PSD harnesses. You will also be able to see the new hardware for mounting the amp. This was a last minute change I made, and the hardware came in early last week. There is a barrel screw running through from the top. It has a 1/4" diameter, which is a bit larger than the rubber isolator/spacers, so it holds them snuggly in place, making assembly much easier than the first method. Installing those long screws blindly through the amp and two spacers with all the wiring attached to the amp just wasnt a fun task, so I think the update is a good one. Cosmetically, it is a bit of a compromise, but it is installed under carpet after all. One thing not included in the "kit" but necessary for the new mounting method is locktite. A small bit of the hand-tool friendly locktite should be used on the mounting screws for the amps so they dont back out because of road and sub-induced vibrations.

I had to hand-modify these first pieces for the new hardware method, but the next batch will have the washer bores CNC'd like the other mounting locations.

Thanks,
Hans
