I would go for around 1 cube per sub then. Depends what you listen to aswell, if it has alot of double kick you'll want to reduce the overhang with a compact enclosure but a low tuning. It'll make for good upper and low end performance, along with 4 drivers that will cover the 'L' part in 'SQ'

What application, SQ or ""SQL""? 0-6-1.2cf is what we suggest, with 28-32Hz tuning. Smaller enclosure will provide a tighter sound with the larger giving more boom and overhang. I would probably go for a 4cf enclosure with a 30-32Hz tuning for all 4 :-)

Big well done for supporting your family through the tough ordeal, cant have been easy for you. Wish you and your family the best for the future. Good to have you back!

Hey guys. Been doing this build since way back in December 2007. I thought it be about the right time to start a build thread. Being the UK/EU Rep for Ascendant Audio, Fi Car Audio, XS Power, Powermaster, KnuKonceptz we saw it only fit to make something to challenge ourselves.. We had a bunch of ideas initially and I started on a relatively small scale of equipment which grew, grew and grew! Scott made me do something I didn't even think was possible but I'm not one to bow out of a challenge although looking back at it I would think twice about doing it again! Went through 10-15 different designs, ported walls, clams, bandpass's etc.. nothing was looking easy.. Measured things over and over till we knew for certain what we had to play with. With the design in mind I went ahead and drew it up in Sketch and worked out the volumes etc.. along with working out the tuning points for the rear chamber. We had a nice healthy 110cuft before anything was placed inside the 50mm thick shell.. tunnel taking out around 25cuft add to that the subs, braces, subs and we have a good 6.3-6.5 per driver. Before I begin with the pics I need to say a huge thank you to Scott @ Fi, he doesn't need any introduction the man is a legend in my eyes. Thanks also to the other people who have been involved in the creation of this build, in no particular order, Mike at CAD (SPL Dynamics), Scottie Johnson, Nick Morgan, Marshall Joyner, Edward Preston, Russ Taylor, Bill Greenberg and my other half.. who has been very understanding with the 1000s of hours spent on the build.

The Clamshell creates what I would call a Phantom port length. The port is calculated on port area and box volume. In my case 462 sq.in of Port and around 65-70 cubes. Nets us a tuning of around 28-32Hz give or take.. This is with 0" port length. The Clam itself is is around 40" long if we measured the angle/slopes. The distance from the end of the port to the back of the enclosure is 20" (it was 30" reduced it to raise tuning and stop the windsheild from breaking every time we went over 158+) So, in my case any port length drops the tuning. This is not to say it wont gain me, It might. The enclosure is far from finished. We have a bunch of tweaks to make and test with and without port length, try some phase plugs and 45s.. A combo of these or few of them will gain us, but this year was about having fun and making a noise.. we'll be working on things over winter for dB Drag next season.. So WATCH THIS SPACE

Video produced by Reelmotion from the ACE Cafe meet few weeks back If you cant hack the sick ass VWs/BMWs/Audis/MERCs... fwd to 3:13

I think ALOT of people forget that when they compare like for like from other companies with anything made by Fi Motors aren't pulled from the shelf and bolted on a basket, it spends certain amount of time being machined and dialed in per application. So add in the cost of the machinery, labor, and TIME. And they wonder why there are some of the worlds most exotic cars bannerised on the Fi website Looking fwd to the NEOS

Oooops! http://www.youtube.com/watch?v=kGYG1N6CIKw

Well.. After seeing the floods on TV throughout Delhi I would just hope they dont get wet LOL Let us know when you get them safe and sound, and when you install some SMDs into a riksha or a 3 wheeler

Manish has the details.

According to the seller it does. Got the following in an email from the seller: I can tell you is that RE Audio aka Destij Engineering designed and build subwoofers for Ascendant Audio when they first started. The first generation of the Ascendand Audio Atlas and Avalanche were engineered and built at RE's location in Henderson. These were the exact same dustcaps. This custom prototype was designed for Ascendant Audio as something bigger than the Avalanche. Perhaps, the prototype version of the Havoc. Whether or not Ascendant Audio is willing to admit it or not, it is clear and evident that the engineering behind their first few generations of subwoofers were not in house as Chad and his father Dale has no manufacturing experience and relied on the build house of RE Audio. This is pure fact and can be confirmed by hundreds in the industry. This prototype was designed and built by RE Audio for Ascendant Audio. And as me and Nick alread said - It doesn't!! This guy is talking utter CRAP!!!!!!!!!!

Enjoy

That has nothing to do with Scott when he was at RE, nothing at all.

Patience!!! Theres not 1 person to call theres hundreds. Since the magnets arent available as there in customs dont panic, there should be no reason why there not with you before the show. Dont go expecting a phone call, or get worried you didnt recieve one. Everything is being done as swiftly as the gods alllows. Thanks.
