Found out that they got held up to be hit with the x-ray twice - fun stuff. It MAY arrive by the end of the week, maybe.

So far the 1500s aren't much liking the 0.25 load. I can roll it and get a score but not high enough to do a GOOD score. So I may just need to wait for 3500s and use the 0.5 DCR load for now and then build some other subs later once I get it all dialed it for the 0.375 DCR load again.

Woops - I made a mistake earlier... must have looked at the wrong data for the subs I was using before. They are 3.0 DCR and not 3.5 DCR as I was assuming before. With those D4 coils all in parallel I had 0.375 DCR per amp, which is more like a 0.5 ohm nominal load. With the D1 Nightshades I built I have an actual 0.50 DCR load per amp, which is more like 0.70 ohms nominal. Even still... it is doing 154.3 dB with a DCR much higher. I may have to wire the amps down lower and try it that way with these coils. Or use a different amp configuration like four 1500Ds wired down to 0.25 DCR each to get a better comparison.

I disabled my PMs. If you sent me a PM and did not get a reply please e-mail me.

Thanks - will look into that!

Unfortunately stuff does happen to delay shipments hence in the first post : "The current ETA is around May 11th to May 20th -- this is a rough estimate. As always, with a pre-order the ETA is subject to change based on shipping delays, etc, etc. PLEASE do not pre-order unless you are okay with any delays that may occur." I will keep everyone up to date I want two for my Jeep as well!

Yesterday customs was still playing with them. So we'll see if they keep to the original ETA.

Yes, they like SMALL boxes.

Either is fine - you really don't need more than 12 awg.

You can buy em when ready!

They were made for 1500 RMS - but everyone loves to run more than rated power on everything.

Wait and see I tore up a sub today @ a MECA show doing drive-by SPL so I'll have to build two new ones for testing.

I trim it down a bit to fit.

Enclosure specs will be very similar.

Not quite in this setup. I am at 0.45 DCR per amp with this setup - so I'd say more like 4k per amp tops.

I am using Stinger HPM 8 awg power wire for speaker wire.

Not quite ready for resin yet.

You can pretty much negate displacement from your calculation as it is so small... around 0.05 ft^3

Use the 1000D as it is rated for 1000 RMS.

Sorry - not yet!

Tried a few things with no success : No change - 155.6 --- LOSS - Down 0.2 to 155.4 --- This has gained me in the past... but not today, did 155.5 dB this way. --- 155.5 dB again --- So no more gains yet!

Yep - any sort of brace, corner piece, etc takes up box volume. So far it has not been enough to significantly alter my frequency or score. I am hoping when I make them into arcs rather than 45s that they will smooth out air flow a bit and add a tenth or two more.

How about IB? We'll see

Yesterday I put in another 45 degree piece: Nothing really changed - did 155.2 dB. Then I drilled holes to get the speaker wires out of the port... no change. BUT they were not sealed up - just holes. --- TODAY I got threaded brass rod, washers, and nuts to make a proper connection : I should add that before I had a smaller wire jumping from one coil to the other to parallel the coils. Now I have two sets of wires going to the common point (this is probably part of the gain I saw). So I am up 0.3 dB from my best score and 0.4 from the score I was doing yesterday consistently. I would say part is due to moving the wires out of the port (this has always gained me in the past) and part was due to the superior connection of running two sets of large wires off the coil.
