If it's still on the list I still have it. I will mark items as sold when they are sold/

I am going to revise my suggestions a bit... honestly 0.5 - 0.7 should be used for pretty much ANY power level. Based on more real world testing with customers -- a heavily abused SA-8 can mechanically damage itself in the larger boxes even on lower power.

Update posted !

For the most part Team membership is for SPL competitors - with a few exceptions for large builds that don't necessarily hit the lanes. Although, 90% of the emails I get for Team membership include zero SPL experience.

* 8, 10, 12, 15 left to right * 8 and 10 * 10 and 12 * 12 and 15 * Close-up of SA-10 cone / surround --- 15s are not yet available... likely will be around end of the year.

I know it's way early, but have you set any price on these and have any specs for enclosure size been tested? I assume they will come in D2 & D4 configurations. Boxes similar to the Nightshades... so about 3 cubes ported. Could go a bit smaller if needed - to 2.5 to 2.75 I haven't set pricing yet.

15s should debut around years end.

Okay guys... ran through a TON this morning and I have less than 10 not replied to. So almost everyone should be taken care of. I am delegating some emails to Brandon for responses so don't be shocked if you hear back from him and not me Thanks for your patience everyone!

Was caught up for a short time but they are backing up again - have been pulled away to build alot of subs recently... Nightshade v.2 orders are coming in quick. In any event - be patient if you have emailed me and I'll get back to you as soon as I can.

Funny thing... coils aren't totally destroyed, just really black. Did not completely unwind yet. The one on the right started to come unwound a little at the top -- both coils still read but read lower than they should (shorted windings). The one on the left still reads normally on both coils ! The former got so hot it bubbled out - this is why they locked up at the end of the video. We hadn't quite reached total coil melt-down yet - but we had exceeded what the former will handle !

It's not an amp - that is why We put the guts of a 1500-watt light dimmer inside that case and used the terminals as connections for it. This way we can adjust the power coming from the wall socket to the woofer.

Once I finalize a few tweaks to the thermal design of the SA series I will begin production... so within a month I think.

So it's not a total waste I took some pictures of the Type-R after we blew it... Brandon took the hammer to it before I got many "before" pictures *laughs* It is worth nothing that you cannot remote the Type-R motor from the frame as far as we could tell. * Around the edges you can see where air vents to the outside in the slits between the top plate. * The special curve on the pole flattens BL * One piece frame / shorting ring assembly... the magnet was busted out to see this... magnet is multiple V shaped pieces.

Well here it is... I was very sad that it didn't last longer thermally : http://www.youtube.com/watch?v=os4TZTpLNSI "Done to compare with SA-12 results... we dialed in power as close as we could but the Type-R didn't last long. Few samples of actual power applied : 28 seconds = 497 watts / 51 seconds = 667 watts / 1 minute 18 seconds = 717 watts -- woofer didn't last much longer when exposed to a hair over 700 watts. Conclusion... SA-12 coil cooling is more effective."

I'm not planning to test other brand subs at the moment... but I was interested in the Type-R for my own information as I was actually pretty impressed with the design behind it. Still am impressed with the way Alpine worked a one piece frame / shorting ring into it... split magnets are cool too... as is the nice BL curve. But I was let down that it wasn't stronger thermally.

A bit saddened... the brand new Alpine Type-R failed after about 1.5 minutes of the same testing (as close as we could get it anyway). I'll put the videos up after lunch for that.

This is the voltage adjustment rig - Brandon's custom creation

So... how many people want 15s ?!

Building a pair right now... on that note - I really do not plan to make any more of these until I get the spiders I'm designing for 10s as it is a bit of a pain in the butt to make these! In any event - someone talked me into making them a pair so here are a few pics :

Glad I can help.

The power clamp reads in kW -- so 0.90, for example, is 900 watts. I kept playing it for 5 or 6 more iterations of the track after the video as I always measure T/S on at least one woofer per run to make sure everything is on track. I've already measured this one once but I've been breaking it in more to measure again

I am designing both -- and both will be excellent quality. I just don't have an ETA for either.

Good stuff Walt !

Just tried the same thing with a brand new Type-R... a D4 model even (this is a D2 SA)... already started to break the triple joint.
