First one is complete. This should take care of alot of common and uncommon questions about our woofer dimensions. I am looking into printing them at full scale on our packing boxes as well. I'll be adding them to the X thread when the X drawings are done and will also add them to our site for pretty much every model woofer we make.

Our ETA is roughly the end of June on these; as always this can vary a bit based on parts supplier production times, transit times, customs times, etc. Based on our average shipping time that is our best estimate. That being said this pre-order will ONLY be open to the public until April 15th, 2013 -- OR until a given size / coil configuration sells 50% of the quantity being produced. I do not want to be out of stock instantly so we are running this much shorter than our other pre-orders. This pre-order is for the USA ONLY -- check with your distributor if you are outside of the USA; if you do NOT have a distributor in your country you can check with us. The below rates are shipping in the continental 48 states; e-mail us or your dealer for AK or HI pricing. Pricing as follows : PART # // REGULAR MAP // PRE-ORDER RATE X-10 (D2/D4) -- $329 -- $280 X-12 (D2/D4) -- $349 -- $300 X-15 (D2/D4) -- $389 -- $330 X-18 (D2/D4) -- $409 -- $350 You can pre-order from any participating local or online dealer OR directly with us via Paypal to [email protected] -- you MUST include a note stating EXACTLY what you are ordering. As is typical with a pre-order the sale is final ; make sure you are not placing yourself in a bad financial situation by pre-ordering. Do not pre-order if you are on a tight schedule ; the dates are NOT set in stone. An adjusted date is not considered a valid reason to request a pre-order refund. If you have ANY doubt about waiting or your financial situation DO NOT pre-order. ---------- The X series is our 1250 RMS rated line -- they feature a 3" diameter CCAW round wire coil and our new frame, spider, surround, and cone platform. Linear x-max is around ~30mm one-way by 70% BL with a total mechanical clearance of 50mm in the motor. These woofers are designed excel in high output DAILY low frequency applications. If you are looking for a burp driver or a driver to excel on “higher” bass frequencies; this is NOT it. We will offer SPL burp style re-cone kits for them at a late date – but the stock format is not made for that. * Z v.4 12 on the left and X-12 on the right. * Z v.4 12 on the left and X-12 on the right. * New terminal blocks ! * Essentially looks like a "mini-Z" style motor... 190mm magnet vs. 220mm on the Z series / 66mm tall stack vs. 75mm tall stack / thinner steel / less expensive round wire coil vs. flat wire in the Z, etc, etc. ---------- Preliminary Specifications : ** The production models have a stiffer surround which will result in an FS about 5-10 Hz higher, higher Qts, etc. They will also have a slightly tighter gap which increases the BL a bit ** X-10 D2: Re : 3.63 ohms Fs : 27.9 Hz (Stiffer Surround = 32 Hz) Qes : 0.43 (Stiffer Surround = 0.49) Qms : 4.7 Qts : 0.39 (Stiffer Surround = 0.45) Le : 4.11 mH Sd : 366 cm^2 Vas : 19.47 L BL : 21.67 NA Mms : 317 g Cms : 102 uM/N (Stiffer Surround = 75.16 uM/N) Sens : 81.66 dB 1w/1m X-10 D4: Re : 5.96 ohms Fs : 29. 15 Hz Qes : 0.54 Qms : 5.26 Qts : 0.49 Le : 6.14 mH Sd : 366 cm^2 Vas : 19.06 L BL : 24.45 NA Mms : 297 g Cms : 100 uM/N Sens : 81.14 dB 1w/1m X-12 D2: Re : 3.7 ohms Fs : 24.35 Hz Qes : 0.37 Qms : 4.38 Qts : 0.35 Le : 3.76 mH Sd : 457 cm^2 Vas : 38.02 L BL : 22.35 NA Mms : 333 g Cms : 127 uM/N Sens : 83.35 dB 1w/1m X-12 D4: Re : 5.84 ohms Fs : 26.43 Hz Qes : 0.48 Qms : 4.48 Qts : 0.43 Le : 5.18 mH Sd : 457 cm^2 Vas : 34.38 L BL : 25.16 NA Mms : 313 g Cms : 115 uM/N Sens : 82.96 dB 1w/1m X-15 D2: Re : 3.68 ohms Fs : 20.51 Hz Qes : 0.42 Qms : 4.81 Qts : 0.39 Le : 4.00 mH Sd : 729 cm^2 Vas : 107 L BL : 21.79 NA Mms : 422 g Cms : 142 uM/N Sens : 85.17 dB 1w/1m X-15 D4: Re : 5.78 ohms Fs : 20.88 Hz Qes : 0.52 Qms : 4.94 Qts : 0.47 Le : 5.99 mH Sd : 729 cm^2 Vas : 103 L BL : 24.85 NA Mms : 422 g Cms : 137 uM/N Sens : 84.34 dB 1w/1m X-18 D2: Data not available X-18 D4: Re : 5.85 ohms Fs : 20.5 Hz Qes : 0.57 Qms : 5.61 Qts : 0.52 Le : 5.92 mH Sd : 1140 cm^2 Vas : 237 L BL : 24.79 NA Mms : 470 g Cms : 128 uM/N Sens : 87.22 dB 1w/1m ---------- PHYSICAL SPECIFICATIONS :

Looking good !

Didn't even try it sealed up ; I don't think he's ever even played it with the windows up *laughs*

As a low tuned setup it's not super strong sealed up but we did meter it at a show over the weekend : Two Windows Down = 144.5 dB Driver Window Down = 145.1 dB Both done @ 30 Hz -- we'll be trying two of them on an NS-1 at some point; shooting for 150 dB with driver window down @ 30 Hz I believe Derrick took a good bit of videos of it from the show too !

I didn't read the whole thread; but I just got back at a computer. We sold one X-18 D2 prototype to a dealer in Florida (Migraine Customs) for them to try out, install in something, and give some feedback on (each prototype has two of each size, one of each coil config). Occasionally we'll let out a prototype to a customer or dealer to get some outside feedback after our testing is done -- this is not unusual or unique to this driver. I do not know what it was sold for @ the dealer to the customer so I have no input on it's asking price. There are a total of two X woofers floating around outside of the shop -- the X15 D4 from SOTM and this X18 D2. The other 6 prototypes are in my prototype room here @ the shop.

If you have a built item ~2 weeks; in stock items usually 1-3 days.

I am working on a 6.5" subwoofer, yes. One with a reasonable depth as well (similar to older JL 6W0 depth).

ETA is ~3 months from now on the X and Z v.4 line. The NS v.3 will debut a little bit after that.

SAX-125.4 active right now ; so 125 per side on the mid and tweeters.

I put the prototypes in my truck -- the midbass is pretty nuts from them. I need to take my doors back off and do some super heavy dampening... we did a layer of Audio Technix new product already (which helped a ton) -- but these things make my doors go bananas.

You cannot re-cone the 8s to any other size.

I am working on a tweeter to pair with the NeoPro mids at some point (likely this year). We'll also eventually sell our SA and NS series tweeters as separates. I don't have a date on the above, though. Just for reference our component set power ratings are 8-hour @ 20 Hz to 20,000 Hz full bandwidth -- we use the highest number that passed the full 8-hours.

We do not have any original parts for them -- yes the specs will change. I don't recall ever measuring one that has been re-build, though, as we haven't really done a ton of them.

Theoretically we could do something like a single NS v.1/v.2 style spider -- it will lower Fs considerably.

Quick video we did on Derrick's phone last night. Lighting isn't fantastic but we wanted to get something up as soon as it started playing. I'll have to work on getting another with my HD camera and some better lighting. SAZ-3500D v.2 (original prototype) on the Z v.4 12" D1 prototype woofer -- single 6" aero-port box tuned to ~30 Hz in a box around ~3 ft^3 or so. The VW has a stock alternator and an XS S3400 battery so we went big on the box to avoid pushing the amp hard enough to drop voltage super low and clip (we had clipping / 11.5v drops in the smaller box). We were getting some very high excursion levels; not to the point of maxing out the suspension but quite a bit beyond what our older platforms are capable of. The video doesn't show this the best so stay tuned for more videos. The goal with the new frame and suspension platform was to create drivers that you don't have to worry about hitting suspension limits -- and that is what we achieved. Even in a big box with a ton of power mechanical stresses are almost non-existent. Jovanni drivers this car daily and is not easy on it so I consider it an excellent durability test !

It's a v.1 model -- we haven't done this test in some time.

It's very difficult to thermally damage an SA series woofer ; I'd go as far as to say that it almost cannot be done "by accident" without hearing severe signs of stress. Are you indicating that the woofers had VERY little output and also smelled ? If so you likely have coils wired out of phase; which will rapidly fry them. In order to diagnose anything we would need DMM readings and pictures of how the wires go from the woofers to your amp to attempt to figure it out.

As Mike mentioned; you can get a re-cone with the D2 configuration, yes

The new NS-1 production run started last month and is due mid to late April coming up : NS-1 -- Website page with details. 6500 watts rated @ 1 ohm Regular cost is $1900 PRE-ORDER COST IS $1500.00 shipped in the continental USA only. AK and HI get quotes from us or your favorite dealer. During the pre-order you can order from us via Paypal to [email protected] or call 704-528-9700 Ext : 3 and order with Debbie over the phone. You can also order from any local or online dealer. International contact your local distributor or online dealer.

For SPL competition and maximum thermal capacity the Z v.3 is still a superior driver. For low-frequency output the X would be superior.

The E8 v.3 is similar to the SA-8 v.1 model but has a bit shorter coil and less motor force -- it uses the same cone, surround, and spider.

We do not sell the SA-6.5CS as pieces at this time. The NeoPro won't quite fit IIRC.
