Cool stuff :drink40: I didn't spend any time worrying about fancy looks on them -- simply a quality cone with good frequency response

I was on schedule to nail it on the head but my container is exactly a month behind... so I ran out before it arrived. Had it arrived right about now I'd be good :drink40:

Measured specs on our WT2 : SD-2 12" D4 : Fs: 35.0 Hz Hz Re: 7.4 ohms ohms Qms: 6.00 Qes: 0.60 Qts: 0.55 Cms: 0.11 mm/N Mms: 186 g BL: 22.5 NA Vas: 29.43 L Sens: 85.3 dB 1w/1m Le: 6.58 mH We used a bit different surface area calculation so our VAS varies from the factory measurement. Also our system measured DCR a bit different too. The main point, though, is that Fs and Qts bothe dropped and the CMS is now close to the goal of 0.12 mm/N I'll measure them all as I get time to break them in for "official" specs on our WT2 device.

SA-12 with D2 coils just sold out about 5 minutes ago. We still have SA-10 D2/D4, SA-12 D4, and SA-15 D2/D4 in stock. A container of all SA series 10,12,15 is due around June 20th. The SA-8s are not due until mid July.

There is as much crap talking in power-lifting as car audio *laughs* 700+ is crazy squatting... I never did below parallel like him and I topped out at 405 for a set of 10 (again, not below parallel - just parallel) @ 195 lbs about 5 years ago. 200 more pounds on top of that and going lower... crazy heavy. Was a bit more of a dead-lift fan myself, though -- not quite record material... but in the middle of a pyramid set maxed @ 545 with no belt or lifting straps (chalk all the way!) -- reps were 225x10, 315x8, 405x6, 495x4, 545x1, 495x4, 405x6, 315x8, 225x10 -- obviously with some short breathers in between sets. No way I'll ever try that again but it was cool at the time when I was younger :drink40: I'll be happy if I get up to 400 again at this point in my life! I have respect for anyone lifting that kind of weight... super hard work involved to get there!

A thin top plate can be over-saturated like in the case of the HCCA so cannot handle all the flux the magnets have the capacity for... also if you have a long coil a shorter top plate will not bring the field out far enough to encompass all the windings and since BL is a product of the flux AND the windings it is reduced. Gauss strength drops with a thicker top plate -- but the BL^2/RE measure may increase or not be effected -- so I prefer it when looking at motor power over Gauss... then take BL^2/RE and divide by moving mass for a good "SPL Ratio" figure. So... moral of the story... top plate thickness depends on what you are going for in the design. With a huge motor like the HCCA, though, for an SPL application a thicker top plate would allow more motor force factor.

Do you mean the BL^2/RE is 92 ? Double the motor force factor would generally result in higher SPL but a bit less low-end extension assuming the same enclosure. It is possible the magnets are not charged well, yes.

You can use an SAX-1200D without turning it wide open -- would be a great match. We are also working on both a 500-watt and an 800-watt amp for release possibly next year... the 800 would power a pair nicely as well or a 500 on a single.

Early price estimates -- MAP price (actual price paid from dealer) (SA cost for comparison) SA-10 v.1 : $185 SA-12 v.1 : $195 SD-2 10 : $150 SD-2 12 : $160 Pre-ordering would be something like : SD-2 10 : $115 SD-2 12 : $125 That would be shipped in the continental 48 states. Once I do some testing we'll have an ETA and a time when pre-ordering will begin.

Yep; sure is broken! Send me an e-mail to [email protected] with your name, address, and phone number so I can send a recall tag to get it swapped out.

Updated List : 2x SA-10 D4 1x SA-10 D2 9x SA-12 D4 3x SA-12 D2 4x SA-15 D2

That is what I have. 2x SA-10 D4 1x SA-10 D2 9x SA-12 D4 3x SA-12 D2 2x SA-15 D4 5x SA-15 D2 These are b-stock subs... some small defect is present on them so don't order expecting a woofer to put in a show-car install.

UPDATED TODAY 5-24-11

It may have been damaged in transit (most likely as we flip all the switches in testing at the shop); send us a photo or post it here.

I will be on the forums and whatnot but keep this in mind this week.

Yep; linear one-way by 70% BL

The specs before break-in period are as follows as measured by the factory (I will break-in and measure again after arrival) : SD-2 10" D4 : Fs: 39.7 Hz Re: 8.0 ohms Qms: 5.45 Qes: 0.56 Qts: 0.52 Cms: 0.09 mm/N Mms: 178 g BL: 24.7 NA Vas: 13.8 L Sens: 83.5 dB 1w/1m Le: 4.06 mH SD-2 10" D2 : Fs: 36.7 Hz Re: 4.0 ohms Qms: 5.51 Qes: 0.48 Qts: 0.45 Cms: 0.10 mm/N Mms: 184 g BL: 18.7 NA Vas: 15.6 L Sens: 83.9 dB 1w/1m Le: 2.69 mH SD-2 12" D4 : Fs: 38.8 Hz Re: 8.0 ohms Qms: 6.18 Qes: 0.69 Qts: 0.62 Cms: 0.09 mm/N Mms: 195 g BL: 23.5 NA Vas: 31.7 L Sens: 86.1 dB 1w/1m Le: 4.14 mH SD-2 12" D2 : Fs: 36.8 Hz Re: 4.0 ohms Qms: 6.06 Qes: 0.58 Qts: 0.53 Cms: 0.08 mm/N Mms: 225 g BL: 18.9 NA Vas: 30.2 L Sens: 86.0 dB 1w/1m Le: 2.63 mH

Prototypes completed over the weekend way ahead of schedule and I'll have them soon ! If these looks beefy to you for a "shallow 500-watt" driver -- they should... the magnet slug is a full 7" diameter x 1" tall slug -- half of the current SA woofer. So it has some heft !

That is something I am interested in making in the future -- as I was getting into audio during the x-max wars with the Brahama, XXX, etc Once I get the rest of the line done -- stuff that sells more and can pay for cool projects -- then I'll get to that

Corey can also do these -- [email protected] Mike may be super busy with his full time job for the time being as this was a side project.

Glad to hear that Jacob, no get to work on those 1000 watt subs cause I want 2-12''s I am still working on some things before launching them.

:drink40:

Just got the accounting system fixed -- so good news there ! Just a bad power supply from the storm we had over the weekend

Shop will be partially closed next week. We will still respond to as many e-mails as possible and as many products as possible will go out. We will not be open for phone calls or be at 100% shipping / building capacity. Don't worry, though, after next week we'll be back to work and we'll have an extra worker at least for the summer ! Also -- bit of a hiccup this week. My accounting / book keeping computer went out over the weekend. I ordered a power supply for it next day air yesterday -- still waiting on it to arrive to start going through orders to enter and ship. Hoping it arrives before lunch so I can get some work done today!

http://www.caraudioclassifieds.org/forum/1238679-post9.html "I have had focal, rainbow,MB quart,and alot of other sets of components and these sound just as good but get ten times louder If u have never had pa mids they have a slight warmer sound then most car speakers and can sometimes sound really flat and vocally mostly because most pa speaker are designed to be in enclosures. But since Jacob designed these to be ran ib these are perfect for car doors. Once u seperate the rear wave from the front (mounting them in a door) they really cone alive and produce very detailed sound. I have my doors sealed up with sound deadened so I have created a true ib environment for the mids. From what I can tell with xover points the Neo pro naturally drops off around 4500-5k and it does so quickly but most tweets should be able to take over from there easily .... all in all some of the best pa mids I have heard Edit/Delete Message" Reviews coming in a bit now.
