I don't have an exact date... just waiting on them to get here. Should be soon.

That was done back in the 1920s... IIRC.

We are going to have a Team get together and weld on it at some point, then it will progress again.

They are 100% sold out for now, sorry guys !

I trim a few strands off an use 8 awg anyway. Not that it makes a different until ~10kw anyway

1) http://www.stevemeadedesigns.com/board/topic/50753-sundown-amp-clamp-tests/ -- More than I tested here at 14.4v 2) No the 1200D is not on sale.

It may be alive again... drove it around a bit today with no issues. So far we have changed: Coil Rotor button Camshaft position sensor Crankshaft position sensor Going to drive it around a few days to see if I'm comfortable taking it to Whiteville, NC for nSPL clamped power classes Then the real no-wall build will probably start after that.

Leaks some oil and burns some oil 251k miles + original motor

Nice work !!

I had an SAX-100.4 bridged on one... which is 320 watts RMS. Did fine.

Around 75 dollars each to pre-order.

About 90-days after I start production... planning a pre-order once I get final preparations in order.

So... who is interested in these guys ?

I manipulated the winding width a little so the D4 actually ended up with slightly higher motor force than the D2 -- good stuff

http://www.youtube.com/watch?v=tCScPpf01k0 Decided to make a video since so many people want to use these in SPL burp applications and high power (50%+ over rated power) and large enclosure (25-100% larger than suggested) applications. For these applications you will want to run a bead of epoxy around the spider as shown in the video. Has worked great for me... have done around 100 burps at over 1kw per driver in my CRX this way... hitting 153 dB. The next run and forward will simply feature a bolted down spider to handle all applications right off the bat.

Should be ~1500 RMS as it is Z v.2 parts in a motor with pretty decent cooling. These are 250 + SH each. Have parts for a few more... if that many are interested I'll go count them.

The frame has a non-standard landing so it was adapted with a steel ring: --- * Center support ring going into place. This locks into place around the extended neck joint on the Z v.2 spiders and is also glued into place at bottom and through it's entire height. * There is a little trough here for glue in the ring... the cone sets down into this area as well and bonds nicely. * Special rubberized surround glue. * Glue trough filled in on the ring - ready for cone to go on. * Spider press doubles as a cone press on the inside of this rig (minus the motor) to make sure the cone stays pressed into the glue trough in the ring while curing. Also used another TSS 15" to press down the trim ring to make sure the surround glue dries nicely.

I occasionally build custom drivers on non-Sundown platforms by request -- few pictures to share These use the Z v.2 light weight 15" cone, Z v.2 production voice coils, Z v.2 production "2 spider" pack, an additional re-enforcement ring at the triple joint, stock T3 TSS frame and motor. With this cone the factory trim ring can also be used unlike the last TSS I built with the wide roll surround. * Top triple joint * Factory trim ring in place * Triple joint ring between cone and spiders. This cone is a bit shallower so there is room between the cone and spider. * The second one being built... this is my spider press rig to make sure the spiders stick well to one another and to the landing. Maybe a little overkill... but I hate to see spiders come off or apart. ----- I'll get a few more pictures before the second one is done too... will also get some specs as the customer requested them. I can actually build a couple more of these too... have a few more TSS 15" frames.

Pre-Sale is OVER -- stay tuned to this thread for updates on arrival. Expected some time soon. More are available for sale @ the regular price this time.

If it's only two channels you may have something - I can check it out.

A pop like that is generally from something else in the system -- head unit or another amp. Swapping in another amp does not rule this out as all amps shut down at different rates.

Did a quick power clamp. 4240 clamped watts = 152.8 dB 1300 clamped watts = 148.7 dB
