comparison pictures massive Magnetar coil
MMAG technology. granted this is the spl coil so linear xmax is only ~10mm. magnetic force in both gaps are within a few percent. The daily coil would sit center of the "humps" which are the toplplates. As the coil loses force form one gap it gains in the other. The daily coil offers ~45mm one way linear xmax. What you see below is the magnetic force across the moving range of the coil

I normally hate that type of covering with a Passion but that looks pretty damn good

Ethos 12 and 15 final pricing and preorder
UPDATE AS OF 8/6/13 spoke with my supplier on Monday. Custom embossed dust caps will be in on Tuesday. The only other parts we are waiting on are the frames which are due in on 8/17/13 (my BD woopie!!!!). If I have not heard from Pat by the end of this week I will call and see when he is expected to be completed with his testing and videos. Pre order will continue till the day all parts are in and ready to assemble. As of now that date is expected to be 8/17/13.

Active or Passive Cross-over?
The cross over was designed to give a certain frequency response in a specific environment. Maybe your environment is different or maybe you just don't like the designed response. An active equalizer can be used to compensate being you already have them. If you didn't already own them it would be cheaper in the long run to do an active set up from the beginning.

The Characteristics of Net Volume and Port Area
It's a 2 inch port compared to a 6 inch port. And a 6 inch port is a LOT of port area for a 10 inch driver with 5mm xmax.

All it needs are a set of tubs and a whipple.

The Characteristics of Net Volume and Port Area
I don't agree, as well as Vance Dickason. It's very clearly written in black and white.

The Characteristics of Net Volume and Port Area
^ agreed as shown in graphs

The Characteristics of Net Volume and Port Area
No, at the same tuning it will not behave differently. Below tuning yes it will unload easier as shown above. The pictures above are the same enclosure volume, different port areas, tuned to the same tuning with increase in power. All while measured on a Klippel analyzer. The out come can not be disputed it is actually real world testing via a calibrated analyzer. Arguing hte fact is akin to arguing that apples dont fall from trees.

The Characteristics of Net Volume and Port Area
Most of the information above was in taken from my SSA Evil. Which has a high xmax value. I have a low score in my current setup, which is 8.3 net with only 130cuin of port tuned at 33hz. I am completely flat from 30hz to 50hz. After 50hz it begins to slightly lose output, but anything below 30hz I have a really big dip in output. I ask these questions becuase almost every program I've used, suggests that I use at least 180cuin of port. Which is far more than what I have. And I believe that the programs are correct because right now I don't believe I am reaching max xmax. Which is crazy because of how much power I am applying (5500 watts). So, this all ties in because, as stated above, my theory is that I have too little port area combined with the power I am utilizing. I am "assuming", that thet too little port area combined with high power is causing me to "choke" the air that is being displaced. Or in other terms, I have too much water pressure to get through the water hose. Can you give an example of what you're saying? Don't need to, your on the right track having a larger enclosure is more efficient and also opening up the port will help release more pressure from the enclosure helping you get Max excursion easier. You do have to be careful with how much you do open the port with your enclosure being as large as it is though so you don't run into mechanical issues. At 180in. Sq I think you'll be just fine and should net you some great gains. No, larger ports do not allow the driver to hit xmax easier. Top pic 2'' port. Bottom pic 6'' port. The top lines in both graphs are group delays and the bottom lines are excursion at each power lever. Very clear no noticeable difference in xmax. Again only slight ripple shift due to FS change. Come on guys this book is only like 30 bucks shipped to your door.

The Characteristics of Net Volume and Port Area
LDC7 page 70 Top picture 4 port. Bottom picture 6 inch port. Obvious that there is NO change in bandwith. Only the slightest bit of ripple change at higher power levels due to FS change caused by non linearity. ALL ports are non linear, no way to get around this. (One reason why I post large signal T/S with my drivers)

Ballin on a budget.I don't even know where to get that anymore. No dealers in my area carry it. I see their website in german or whatever, but it all looks cheap as shit.- Ethos 12 and 15 final pricing and preorder
Why thank you sir, invoice will be sent on Monday during normal operating business hours.- Ethos 12 and 15 final pricing and preorder
In the recommended enclosures 1.5 for the 12 and 3 for the 15, it will take ~1,700 watts for them to hit 32mm xmax. So if you couple two the two 12's you can expect them to hit around 16mm one way at ~1,700 watts. Given the slight increase in sensitivity on the 15 and add in the cost of two 12's over the 1 15, I'd do one 15 if you plan on staying around 2k- Ethos 12 and 15 final pricing and preorder
I designed everything so that everything is fairly interchangeable.- Ethos 12 and 15 final pricing and preorder
No worries I'm just excited and curious. Still trying to decide between two 12's or one 15. two 12's will work in the same enclosure as one 15. 3 feet tuned to 32 for relatively flat response or 36 for increased ripple form 50-30 hertz- Welcome to the IHoP v.2
