Gotta pick two LFE, small box, and high efficiency -- can't have em all.. I picked more LFE and small box, so they aren't incredibly efficient. Of course, on subs, efficiency is kind of a misnomer... as a sub with a lower "sensitivity" will usually have more output down low. For instance, I modeled two sets of parameters -- one set lost 3 dB of sensitivity but had more output under 50 Hz at even one watt levels. That is the one I went with as most people consider "sub" output to be pretty low. They are IB compatible in-car. IB requirements are a bit different in-vehicle, notice how low the Qts is on the Adire Koda 6 midbass? Ever heard one? I talked to Dan about this and IB is totally different in-car than in-home due to the small cabin and how the doors actually behave as enclosures. Extension will likely be limited by cone resonance around ~200 Hz on the top end as it's not a cone made for anything more than low-end work.

Probably stamped, the proto will be stamped. A nice one, though

He can get 300 - 325 for it as long as it is in excellent condition. That seems to be the going rate.

Hmmm... didn't think about that! I'll have to ask James about it.

It's alot... ~33-36 mm or so. It can move more than the 12-spoke basket can handle.

Sure does look alot like the TB T/S specs, huh? Didn't notice that before. I know mine will look nicer *laughs* Shooting for better motor cooling as well. We'll see how the proto pans out. I might have to work on it some more but I'm thinking I like the idea.

*ponders* I may be able to match that price... this woofer is pretty well comparable to the RE-8, although, it has WAY less moving mass than the RE-8 does.

What was the RE8 going for ?

I usually worry about stage second in my cars. I don't compete in SQ so it's okay I prefer mild or no T/A even if stage is off a bit. You are right, it does sound funny with too much processing and T/A going on! As long as I get a good sounding response and a reasonable stage I'm good to go.

I had to tame the LPGs to get them just right, but with a few hours of EQ work... I didn't experience any ear fatigue to speak of at incredibly loud volumes in his car! Very impressive for me as my ears are pretty sensitive to harsh and fatiguing tweeters. Even used the aluminum dome LPGs in there... relatively off-axis in the A-Pillars and I did EQ separate left to right (right is more on axis with the driver). It's phenomenal, really I simply can't get the SS drivers right... fatiguing no matter what I do and I have a 3Sixty.2 for processing and active crossover ability to boot. They sound quite good @ low volumes but just wear on my ears rapidly when turned up. If I can figure out how to get an 8" driver in my door and still get the panel back on, I'll do it! I already have my window blocked up so that is no problem -- my concern is the metal bar behind the speaker hole and getting the panel back on. Not trying to hack up my car too much at this time... the other item in the works should do very well for midbass without resorting to an 8" driver.

Sounds like under-voltage protection if adding electrical upgrades made it better. What size alternator do you have? Power wire size? Upgraded big-three wires under the hood?

Don't worry, I've got something in the works to get rid of those... oops... did I say that out loud? I can't take em' much longer... they sound pretty good but are fatiguing as can be. I can't listen to them loud at all... after installing some Seas midbass / midrange and an LPG tweeter in a friends car (awesome, by the way) these defiantly have to go!

I've got a proto coming in just to see it I'll see how it does. Best part is I would be able to offer it at a really great price... I considered building them and selling them direct as a "specialty" item as I'm sure that 99% of my dealers will never sell an 8" woofer.

I believe it was a 7KD Stetsom, which is rated 5000 @ 12v and 7000 @ 14.4 volts. It is their big boy.

The XXX coil has to stay the same length to effectively utilize the XBL^2 motor. The BL curve will get all wacked out if you make the coil longer.

Come on now, guys! Am I going to be in Indianapolis all by myself? *laughs* Someone will be there with my stuff so I'm likely going there

0.5 or so should be good to go mechanically.

This is an option I only suggest that much power in tiny enclosures as the woofer doesn't really need tons of juice to get moving!

Gotta follow demand No worries... I'm still developing amps as well, but I need sub lines to satisfy my dealers.

Sure will You can run them to a 4 ohm load on your 100.2 no problem. Like I said, they are just as efficient as the original SD-1 (actually 0.1 dB higher on sensitivity) -- but they have the potential for more thermal power handling and more x-max.

Sure did It will move a surprising amount for a 4.5" deep speaker! The primary target market for this woofer is under-seat or behind-seat truck enclosures, especially for those who still want a great sounding woofer for this application. The 4-spoke cast basket allowed me to make this woofer even shallower than the original SD-1 AND increase linear excursion capabilities. The same narrow profile surround from the original SD-1 was utilized to avoid "smacking" the floor of the truck, or the bottom of the seat (depending on orientation) -- it still allows substantial travel beyond the actual linear capabilities of the motor. The two prototypes will quite likely go directly to a customer through one of my dealers... at which point a good 3rd party review will be available on the protos to see if I met all of my goals!

Thread cleaned up... Re-Coned 15" SI Mag added.

You'll be good, especially running the 3000D @ 2 ohms.

There are still SD-1s in stock, any more love for them?
