There is no noise when pushing on the cone. Your thought on such an large enclosure was too my initial thought as well, but I recently made a visit to the Dcon setup with new enclosure, and to my suprise, the noise was still present. Initial setup of the Dcons was done by a shop. I assume that sure, it is possible for the 1500 to damage the pair, but the power is distributed evenly between the pair, and are identical drivers, so in result, shouldn't both be damaged if that was the case? When I tested with my 45hz port, and adjusted the ssf accordingly, I began to slowly turned down the ssf while monitoring the subwoofer, and the excursion on the Zcon looks amazing, as far as to the eye, and did not hear this noise until extreme excursion, where I than adjusted the ssf. But currently, this noise, at 37hz tunning, is present way before reaching Xmech.

I am a proud owner and representer off SSA line of subwoofers. I have owned the Icon and currently the Zcon, and have installed a pair of Dcons. All three sound great, the Icon being my favorite at the moment. The problem that I am encountering right now is the stress noise I am hearing on lower notes at higher volume. This first became apparent on the install of a local Dcon's. Where we began testing and preparing initial gain setting. His setup consisted of 2 12' Dcons on a single AP1500 in a sealed enclosure for his maxima. This "scratching" noise was only noticable in a subwoofer at higher volume on lower notes for only ONE subwoofer, while the other showed no signs off stress. Yes, I am well aware of the amp providing more power than rated, this is not what I am concerned with, the problem relies in only ONE subwoofer, so for only one to show signs of ware, seems strange. That box was built to specs. He then tried moving to another enclosure that Sean DeYoung was nice enough to sell us. It was ported and as well built to specs. The problem still seemed to be apparent in the exact same subwoofer. I didn't know what to tell him as it was strange to me to see how only one could be effected and not the other. On to my setup. I have a build log, that some members have seen or taked a look at one way or another. I have only built one enclosure for this Zcon, and am powering it with an AQ1200, so I'm providing half the power as rated. But the enclosure is a bit on the large size, in the lower 6cuft range. Which was done intentionally to try and compensate for the lack of power. My subwoofer is too making the exact same noise. This noise sounds like coil rub. I first began to think, well maybe its the enclosure being too large, which in result, could cause the subwoofer to lose control of the cone or something, I'm not exactly sure. But once I noticed my local 'ssetup making the same noise in two different enclosure, I'm beginning to think that this may be an driver issue. Either subwoofers are NOT blown. His Dcon was BNIB, my Zcon was a hammy down, but from members here that I have no reason not to trust. IIRC, Ricksi was the original owner > Edouble > Me. So the likely hood of being mis treated or mis used is rather unlikely. Troubleshooting steps that have been taken. His setup, D4 subs wired to one ohm on AP1500. Wiring was tripled checked about 2 times by me. Initialy wired by a local shop. In new ported enclosure, wiring was down by a seperate local audio shop. Coils read fine. Softly push down on top of cap to listen for any abnormal noises My setup, D2 sub wired to one ohm on AQ1200 Wiring has been checked multiple times over and over. Ports have been changed in the range of 32hz to 45hz. Box positioning have been changed. Have attempted different enclosure, the enclosure for the Icon by audible sounded worse (4cuft,34hz,very low port area), and the comp enclosure built by shizzzon wouldn't allow enough port(5cuft) Softly push down on top of cap to listen for any abnormal noises I have asked the local member here, owner of the Dcons to email Support, and here is one of the responses.

Maybe there was an shipping issue, being mishandled by UPS, not sure. So my main question here is what could cause this problem with lower notes at higher volume? I don't really care for whom is at fault, I would be more satisified if this issue could be resolved without the need to purchase a recone out of our pockets as it seems we have had no influence in what appears to be a malfunction of the driver. How do we prevent this kind of incident from happening again? But again, I'm no subwoofer designer or have any idea what could be the issue and what exactly is causing, I am simply looking for an answer. In advance, thank you for your help.

Nobody has this, but I think you should get a Figh BTL

waiting for video

Very nice draw up

Been waiting for clear skies. Looks like it won't be until Monday In the meantime, how about an accidental self-portrait? Was trying to take a video and snapped a photo instead! Upon further inspection, I rather like it. Photographers always say to take pictures of people. Perhaps I should investigate! I have this eerie feeling you might not be wearing pants in this photo... lol I spy someones teddy bear... awwwwwwwwwwwww

Looks great, what will you do for terminals?

nice vid for sure

nice

Sounds good to me sir. Also, in my opinion, theres no such thing as "audio battery", just like theres no such thing as "audio wire". A battery is a battery, now each battery produce may be designed for a different role, but what you have listed will be great, especially with an adittional alt.

I so need to copy this to the desktop SSA Icon Fi BL or Q Ascendant Audio Havoc Incriminator Audio Death Row Sundown Audio Z RE Audio SX DC Soundlab Level 4 or XL Audioque HDC3 Digital Designs 3500 Treo Engineering CSX

yup, lots of sanding will get that fixed. I used 60 grit, may have been 80. Once it begins to slid in, it will leave black marks, from the paint touch the baskets, those are the areas you need to begin sanding down.

40"! I wonder why so many ppl dislike it when people put big rims on vehicles, but not as much negative remarks towards big tires? Can't wait to see pics!

Is that true? He's been holding it for a while now.

sweet!

<p style="margin-left: 40px">Exactly what is the leasing period? 30 days?</p>

amazing scores

Thanks guys! I'm scared to install it though. If you had a million $ ring, would you want to wear it? Is how I feel right now lol >.<

great, will you also post the scores, before and after with equipment used prior to ssa and current ssa, that would be awesome! Great showing Team SSA

lol I know what did it.... Hope it feels better and I'll remember to go easy next time

Muy Bueno in my other language!

So once everything is in, what will the specs be then? I'm curious as how the zcons will perform with so much space and all that power

Nice job julian, We all know your going to want to upgrade 2 weeks from now Might as well through two more in there

I love the progress!
