Taken care of!

Sub is in transit..you should have a tracking number. It is scheduled to be delivered tomorrow. Email was sent via UPS quantum view to thismikeknows at yahoo.com

It won't die within seconds.. You must consider if you draw 2000 watts out of your battery, then you must have 2000 watts worth of alternators to replace what you have just taken out. Otherwise over an extended period of time things will eventually go..dead Efficiency is somewhat of a joke in car audio anyhow...because you are only getting 1% out of your speakers, vs what you put into them. 99% of the energy in a 94.1dB 1w/1m speaker is wasted as heat.

Definitely will!

Ok, I'll check today.

Uhhh.. You should have had that a long time ago unless it came in with no information and it is in the stack of misfit no home speakers.. If we don't have a name or something to work with there isn't much we can do.

Might already be done...I'll check today.

I've got my BTL tuned to 15Hz personally

Nope.. As it is something that VERY few people are going to need. Unless you plan on running a superstreet burp vehicle the sub simply has entirely too much motor strength. N2 is the way of the previous 2nd generation BTL and will do what it was intended to do. Musical applications.

He is taken care of. Relax.

Don't have anything from you at all. The last email we have from a "Linda" was on 9-23-2009..and that is not with the [email protected] either.. If the question is in regards to an SSD order we are just getting the magnets in on Monday..they were held in customs which is totally outside of our control. What questions do you have? I'm sorry but I cannot help you if I do not get the email...

Need a name..or an email address to look for or something to work with...

Generally don't go over emails on the weekend...sometimes I do. It depends on what I have going on and if I have 10 minutes to run through some. If you have emailed and did not include a subject title odds are it is stuck in a spam folder somewhere..or it simply did not come. What is your email address? Do you need something changed with your order or something?

The problem you are going to run into is the ability to put the sub box into the trunk..unless you decide to build it in the car.

To the OP: I'm not sifting through everything explained in this thread. I'd suggest picking up a solid set of components with silk dome tweets. If you are looking for something with a wide range of adjustability then you are going to need to pop for a set of components that does not have passive crossover networks, but ones that are controlled actively by a processing headunit or external processor (like a rockford threesixty.2) Single ported 12" SSD and a ~800-1000 watt amp will likely be fine for what you are wanting to do. It will be loud..and still sound very clear provided things are setup and tuned properly. If you are planning on hair tricks and moving cups around in the car, you will need to go bigger. But that does not mean that it can not still sound good either.

It used to be on ROE years ago...i don't think it's there now though. I have not been to that shit hole in yeaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaars.

Done things like this in industrial applications with electromagnet(s) and inert gases.. Nitrogen is WAY too cold, you can't do that. Again..the car audio market can barely support what we have going on with Supergauss. A wise man never pushes the market farther than it can support. Edit: Scott did the XMX 6.5 that was a 6.5" woofer that moved 4" linear...which for the market at that point, and still is not supportive. We can do really crazy odd ball make your mind go 'WTF' stuff...there simply is not a market or a need for it at this point and time. It's the difference in truly making your own products, understanding how they really work...instead of slapping UPS labels on pre-built conventional woofers from China. We will continue to do what we are doing now in the car audio segment..when we feel there is a market and it is large enough to support making things for larger scale manufacturing then we will go that route..until then they'll never be seen here.

This is the only black Fiday sale we are doing. Don't ask for anything else..this is it. We use a similar motor design for an OEM client, and now we've got a ton of them...so we thought we'd do another black FiDay sale since people were asking if we were. We're not saying a time frame of how long they will be on the website, once they are on and up they will be available to purchase, once they are gone they are gone. I will announce when they are coded and up on the website for purchase on this forum. Old X series 10's and 12's with pricing: $75 - 12" D4 for one (1) $70 - 10" D4 for one (1) 5 bucks off of each at two (2) 10 bucks off each sub at four (4) Plus shipping to where ever you are.

You can get a glue kit from us in the accessories section... I'd highly suggest using 15 minute epoxy on your first recone though. It gives you way more room for error.

Yea my name should really be AmpSam I could go for days on anything Electric Power but I know very little about how speaker motors work physically other than some diagrams and calculations from a sophomore fields and waves class... I see lots of curving field vectors interacting dynamically with a larger fixed flux and my brain just gives up when I try to imagine the sinal wave in from the amp translating into an accurate sound pulse, I just decide I'm too tired to think anymore Anyway your job is fascinating, I've enjoyed lots of professions, can't say I've gotten to play with as cool of equipment as you guys tho (maybe the 500 MHz NMR in the chem lab, but its kinda boring)... Magnetics is fun stuff once it clicks I'm diving more into your side of expertise of things as of late...keeps the mind sharp to work on other industrial projects

Exactly 3D FEA can only get you so far...if you don't understand the why's and how's behind it..you simply won't get it at all. It's really easy to take a xerox and hit 'copy'..doing something like this is a bit deep into left field for the car audio crowd

I've said this a million times. If you want to have ultra low frequencies, tune low. If the sub has enough coil to move...it is going to play them. None of our subs have any problems doing any of it..

Right off the top of my head I am wanting to say 28ish pounds. I'll have to ask Scott to throw it on the scale though to be totally accurate.

A Q coil, and a ultra low inductance coil as well. The low inductance coil will really kill thermal power handling though...but this is being targeted towards SQish applications.

Sorta.. It's a completely different understanding on how flux flows and works.. Generally speaking it is a fluid dynamics problem meets physics meets mechanical engineering and a dash of electrical engineering thrown in as well..given your background i'm you are all too aware of that one . Scott and I did the very first original N2..and for some reason I was looking at it with a smart ass little grin when I was machining the parts to go together and yelled at Scott to come out in the machine shop.. Simply said "I wonder what will happen if we make this thing a half motor...just to really mess with peoples minds" ..and here she sits now ..simply me being a complete smart-ass and it works beautifully.
