Sample motor due soon... pretty excited.

I don't think a video of a comp set is too exciting Nick has been testing them in his car the whole time for durability. So far so good.

I am working on alot of things.

It can make noises -- also if the driver relies on the pole vent for air cooling it can hinder thermal performance.

Part II... only took a little over 24 hours to upload *laughs* AT&T DSL Upload speed fail.

Either.

No problem Glad you like the sound of them ! If these sell well I may design a more high-end version of this line as well -- just need to see if this type of thing will sell well for us

Making it "look cooler" with a cone coating, different cone, different surround, different dust cap, etc... would make it sound worse or at the least make no change and cost more. Same with a "cool looking" frame -- the one used supports all the throw we need and these are super light so no need for cast. Anything else would be throwing money down the drain, IMO.

X2 The only thing I don't like about the looks is the surround. Wonder why Jacob went with the "W" shape. Waiting to see what you say about their performance. It's a cloth PA style surround -- those are generally in W or multiple ridge shape. They are lighter and more efficient for this type of driver.

My DSL connection upload speed is SLOW so I may need to re-start it on my work system. I'll check on it later as GoToMyPC is also down this morning so I cannot remote in. In any event... the depth issue is a large reason for no vent. Then way this driver is set up the coil still gets cool very well as you can tell.

That was the triple joint ring hitting the top plate. Correct. I designed it so that ring hits before the coil -- coil smashing steel is alot more damaging than plastic ring smashing steel

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!

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.

Could not break it... part II uploading now as well. This thing is super rugged.

Taco, Paco, and I have spent the last half hour trying to break the SD-2 prototype with no luck... two YouTube videos coming up. Ran out of camera memory on both of them trying to break it *laughs* PS: Taco and Paco are summer interns.

Little bit of testing while breaking it in for T/S measurements. Getting on it pretty hard here in the video.

Debatable... I don't really want to make 18s but may eventually do it if people keep bugging me *laughs* The next line up will have 18s

Perhaps get a custom made fiberglass box with an aero-port ? That would look really good Scott Bowman from Team Nemesis could make one I'm sure -- he just did some nice door panels for Johnathan Price : http://down4sound.com/forum/showthread.php?t=5619&page=10 Highly suggested guy for this type of thing as well. Yes, we do sell kits for the NS v.1 still -- we have full re-cone pricing here: Yours looks like one of the first run of them from the profile picture. If you want a Sundown tatoo that is okay with me

Yes and Kinda Following Sundown tradition they will be pretty rugged too... obviously with less x-mech and a smaller coil not quite SA level but more than you would expect from a 500-watt "shallow" driver in this price class.

These are much deeper than the BM MKIII and also do not feature a linear BL topology. So in effect they are quite different woofers.

The UPS return tag should be in your Inbox.

Motor diameter is the same, actually. SA looks a bit wider with the boot on is all -- both use 180mm diameter magnets. The SD-2 literally has one SA motor magnet slug. For sealed the 10s will enjoy about 0.5 cubes and the 12s about 1.0 cube or so... can go smaller with poly-fill if you like.

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:
