We are working on other baskets, yes. No public info yet.

http://www.extech.com/instruments/product.asp?catid=14&prodid=109 There is none with my meter -- it reads out power in kW

The finalized frame tool with production finish is done so I'm starting a thread to hold photos of all the parts as they finish up... we should have the rest of the tooled parts done the week of the 24th and the motor likely before that. So as I get images of the final parts I'll put them up!

That is the output filter inductor -- looks like the solder may have broken loose. If that is all that is wrong Chris could fix it easily. If it's major we actually do have a few complete spare boards for those still.

These are due in less than two weeks so get your pre-orders in now !

Truck On -- we believe one of his alternators is going out as it usually holds 13s to 14s but he has two Mechman 300-amps and two XS D3100s.

:drink40: Hope he doesn't get in trouble for it, though!

0.33 nominal load -- DCR is 0.28 ohms (D4 SPL Coils) So it's not a ton lower than a typical "half ohm" load DCR of 0.35 ohms.

Also... a Class A/B amp can be up to ~65% efficient (counting the power supply) at FULL power but when used at lower levels can drop to 20% or so... sounds weird but using less of the maximum potential of an A/B amp can cause it to over-heat. Say, for example, you are crossing over most of the bass region for component sets you are in turn using very little of the capacity of the amp so are likely running around 20-25% efficiency at best. Example : 1000 watts @ 65% = 1538 -- 538 watts heat 500 watts @ 20% = 2500 -- 2000 watts heat So at half the power you are dissipating nearly 4x the heat.

What you are seeing is a higher % of the total ownership of the brands like Sundown, DC, and AQ on the forums -- you always hear from 100% of unhappy customers but only 1% of happy customers For every 1 problem you read about on the forum there are 99 other guys with their amps running around every day with no issues at all.

Yep, we made a few small tweaks and all new units in stock are as such.

Here is a newer one we did recently.

Were you plugging the RCAs in with the amp on ?

With the 8s we've noted it's MUCH harder on them when housed together in large numbers like that -- we had a heck of a time with Jared's wall. Subs were moving a TON with way less power than when houses alone. If you can try to fit a bunch of SA-12s -- we've seen much better reliability this way.

Phone hours will be 8 AM - 2 PM minus 12-1 for lunch the rest of this week (has been this way for a week or so already) -- but will be back to normal next week. We've had to work around a bit of an odd work schedule for a bit but we'll have it back to normal next week

Right... sorry about that. The original frame is 1/8 bigger -- I'll make a note.

Testing 400-watt E-15 prototype in free air. As per my comments in the video we'll have 8mm more rearward clearance on production (16mm p-p) so the driver will support even more throw before any mechanical tapping.

I am looking into starting production in less than 30-days... so keep your eyes peeled for a pre-order special.

Z v.2 / v.3 and NS v.1 / v.2 can be sealed with decent results ONLY on 15s and 18s -- but it's still not optimal. Z v.1 can be sealed no problem. SA series on down works great sealed.

Congrats to the winner and thanks to all who contributed ! Watch the video to see the winner (don't post and spoil it when you watch) -- Nick will be in touch with you shortly via e-mail

We just drew the winner... video of drawing is uploading.

Sorry to hear the bad news -- but I was glad to help with SOTM

Doing the best I can to reverse calculate the BL on the 1500 series (had to guess on the DCR as it's not listed) it seems the most comparable to these; assuming the same DCR the BL is darn near dead on even with these -- the 1000 has a weaker motor and MUCH higher Qts. I am not up on the coil spec of the 1500 series (winding length) but I don't imagine it would take much more if any more juice than these thermally as these have one of the highest I've seen out of a 2" coil yet; even from longer wind lengths. Sound-wise the DD will vary tremendously as DD drivers usually do as a result of the non-linear performance of their spider pack (which also happens to be beneficial for SPL at higher frequencies) -- it creates a "punchy" sound which many people enjoy (also described as "warm").
