Guest Posted April 14, 2014 Report Share Posted April 14, 2014 Why is your sub making weird noise :/ this Link to comment Share on other sites More sharing options...
DubNDodge Posted April 14, 2014 Author Report Share Posted April 14, 2014 That's the reason I was pulling it. I have NO clue. Never bottomed out, never blew smoke. Coil was bright and shiny. But Nate, remember how I said mine got stinky after 15 minutes full tilt? Maybe it was that one. I am disappointed in how these handle the 2200 when they are rated 1200w a piece. I talked to soundqubed and whoever I talked to had their head up their ass. They act like I was clipping out my ass. I told them that I know when I clip because I'll drop lower on my voltage. They said that just because I drop lower on my voltage it doesn't mean I'm clipping, actually I'll pull up or convo because it pissed me off that much. Hi, just recently I noticed one of my HDS300 12's producing an odd noise. Much more noticeable at the higher frequencies such at 70-80hz. Down around 35hz it isn't as noticeable, but still there. Before I purchased these I asked if they would be a direct drop in for the same box I had for my sdc2.5s; 2.25cuft per sub tuned to 35hz with a center port. On a 2200 tuned with a DD-1 -5dB tone. Subsonic @ 26hz, LPF @ 80hz. Most my music I play is about the same recorded level. Note, none of the settings were changed when I swapped out from the 2.5s. Here is a video of that sound I was talking about. I am assuming it is the dust cap, without any further inspection. Also a side question. I realize these are a 3" coil, but do they use less copper then the sdc2.5s? After 15 minutes of playing them they start to smell just as my sdc2.5s did with the same amount of play time. I assumed that they would handle the power much better than what the sdcs had. Considering these are rated for 2400w rms (together) and I am maybe giving them 2000w with rise and the voltage drop (down to about 13.1). I can tell when I am starting to clip because my voltage will plummet down to 12.6. But that isn't the case for these 15 minutes of play time. Thanks for your time, Grant K That smell you are getting is not from the woofer being at fault the smell is from having inneficiency in your power. What charging system upgrades do you have? Also voltage dropping does NOT constitute clipping. Clipping is due to a dirty, distorted signal, voltage dropping can effect the amount of clipping but is not the primary factor. D1200 up front. D3100 in rear. 120a stock alternator. Big 3. Ordered a mechman 240a and putting that in this weekend. All 1/0 Knu. And what do you mean by inefficiency in my power? The reason I mentioned clipping and voltage drop is because the amplifier is drawing more current than it would normally playing a clean signal D1200 up front. D3100 in rear. 120a stock alternator. Big 3. Ordered a mechman 240a and putting that in this weekend. All 1/0 Knu. And what do you mean by inefficiency in my power? The reason I mentioned clipping and voltage drop is because the amplifier is drawing more current than it would normally playing a clean signal Also, You could be going non linear once you get up in to that range dependent on your box. Else fails pull them out, check the coils. If they need to come back here for us to give them a look over please fill out an RMA located under the warranty section of the site! So that is the coils making that noise then? More than likely. We would need to get them on the bench to see what's going on with them.

Swordlordboy1234 Posted April 14, 2014 Report Share Posted April 14, 2014 If you knew what my alternator guru in Fort Lauderdale and a couple well respected guys in the audio industry (that will remain unnamed in this post) say about almost every single alternator company except 1 currently, you wouldn't want to nut hug any one particular brand. That goes for both Nate and grant.. This coming from the guy with the tenney alternator of course. (For now) I mean if it works it works, great. But there is only 1 company that uses every part brand new with proper spacers and doesn't use old stock alternator casings with inferior cooling. A good example is a singer 320hairpin I ordered. Directly from singer. Looked beautiful, but after my alternator guru tore it apart it didn't look so amazing any more. In fact he took out a 160amp alternator from in his office and it was identical. Singer is known for his large case GM alternators and this was a brand new 320a hairpin of his. But after dissection, my alternator guru wouldn't let me leave with it unless he put proper lock washers and spacers behind the pully. There was almost zero meat for the alternator to bite on to the pully. It was brought up to his spec and its a great alternator, not that singer did a bad job but it makes me wonder how many other alternators don't have a safe set up behind the flashy powder coating or flashy pully caps. I'm just saying no one brand is God, but this is just what ive seen from the multiple HO alternator disassembles I've had him take apart. Once I save up $700 I'll purchase that last brand that uses all 100% new parts and see what he says about that alternator build and parts quality.

soundstream15 Posted April 14, 2014 Report Share Posted April 14, 2014 Yeah dude your not clipping at all, maybe a soft clip but that's not gonna do it. I got 3k maybe a tad more to mine and I havnt had any issues man:/ they move a shit ton tho!! But no issues Sounds like It's a defective sub man.

I just went with mechman because they were affordable and have been proven. No they are not DC, but then again I've heard complains about DCs CS and their attention to alternator mounting. Honestly I'm not drop dead impressed with it right now anyways running at 2 ohm needless to say. We will see once I get everything up and working again.

soundstream15 Posted April 14, 2014 Report Share Posted April 14, 2014 I never smelled my coils man. I don't bump for 20min solid tho. But they should take the 2200 with zero issues.. Link to comment Share on other sites More sharing options...
