IMO... poor way to start the message - I don't actually see every post on the forum so I'm not ignoring anyone. In any event - the Xmax is the same as the 12s @ 19mm one-way linear. 1w/1m SPL is not really needed for any reason for subwoofers as it's measured at 1000 hz, IMO - but in case your program calls for it the figure is 83.3 dB

Yep, they are a dealer now. That doesn't change anything about what we do or how our products perform. They will be following MAP pricing like everyone else - this was made very clear. Folks that were going to buy from SSA, dB-R, Tech12Volt, Subtilis, or Powermax still are going to do so - but now there is another option. They have had numerous calls about our products so they tracked me down to ask me if they could carry our products - previously they had steered customers into other products that they did carry since they did not have Sundown Audio. Now they do - so more people can enjoy the product line.

yes I had dual 1.4 coils on the last subs and was expecting my cone rise to go up however it did not? I ordered dual 1 ohm coils so now I am having to run each amp at 1ohm rising to 2 ohms? I am now getting a lot less power but still have a lot of testing to do! Are these D1 a real 0.7 DCR coil ? May have pushed you a bit too far down and would actually maintain your ~3x rise from DCR from before. Tried just two amps at 1/2 each ? Should net more juice than four amps wired up higher.

We are trying to grow slow and steady... spending alot of time on each and every product. I don't want to spread myself too thin and come out with something that isn't the best it can be.

Such as what ? 0.25 nominal ?

We've really spent alot of time on improving glue joints -- it's very critical in this type of woofer. We gained alot of experience with different methods on the v.1 Nightshade -- some worked and some didn't... it was really a huge learning experience in how to make woofers take more abuse. Also, big thanks in order, I spent some time studying the work of David Moore (FixMySpeaker / PSI) down at SBN and took away some good tips from him -- having built thousands of speakers he was a great resource to learn from. I have alot of respect for Dave and his custom work and refer customers to him often -- and I am very thankful for his advise!

Yep ! I started on the 3rd one today. Brandon is tied up building a bunch of woofers for Russia so I'm working on yours myself.

We, Sundown Audio, are putting in another SAX-1200D and a pair of SA-10s.

Did you go with a lower DCR on these than what you had ?

Because it needs 250 amps of fusing - that is alot of fuses to put in an amp Also it is an SPL competition amp and when you run an amp down really low it tends to blow internal fuses. Yes, fuse it shortly before the amp.

Obviously this does not cover EVERY step of the process But you can get a good idea of what goes into it !

A customer ordered four 15s and I am just about done with the first so I took a few pictures along the build process : * Rear triple joint glue and ring - the ring is smaller than the gap and centered so can go down into the gap at extremely high rearward throw. * Close-up of the glue. * Spider pack is pressed with a laser cut steel plate and a Z v.2 motor to ensure good bonding of the glue between the frame and spider layers. * Terminals have a locking toothed washer * Soldered - and a dab of glue added to the stud on top of the nut and washer for long term safety. * Special surround glue - dries flexible and won't hurt the surround material. * Finished cone to spider joint. * Top triple joint ring initial placement. * Some glue added. * Final glue bead. * Leads fully encapsulated. * Leads placed into the cone - care taken to allow adequate slack for high excursion. Suffice to say the NS v.2 is put together quite well.

so 2-3 years? Hopefully not that long - but we will see

I may end up re-designing the 400-watt line before it's release... still working on things.

Plan is to fill out our sub and amps lines fully first THEN do components.

They are available to buy now -- there will be some lead time... at least 5-10 days to build right now. What size ?

The rings actually had a function - to lower inductance. It could get too low, though.

On 12v Derrick was able to get over 3300 out of it at 0.25 ohms -- typically on 18v they get alot more touchy at 0.25 -- I have tested the other SAZ line amps as such successfully with a roll. Just haven't had my 18v system back together to test the 2500 yet.

Working on it... 100 or so done so far this morning between other work.

I haven't caught back up as expected yet.

Yes, on both NS v.2 and Z v.2

Just finished #4 and #5 production units built so far... have many more to build next week. This is a pair of 15s for a Team member - typically the dust caps are silk screened but we ran out so these will get vinyls with the logo tomorrow : May even have test results from these as early as tomorrow.

Terminals are here - they are SWEET... made by "toolmaker" on the forums. We are also working on rear distribution bars for the CRX. I can do initial testing without those, though.

I haven't done 18v testing yet.

That isn't normal... it could be that the value of the knob for 3/4 gain is too high of resistance, though, perhaps a worker grabbed the wrong one. As long as you can adjust it and make it equal though it won't hurt anything.
