Broken Hds210...fixable?

[Badseed]

Hey guys, recently threw 2 of my soundqubed hs210's on my hifonics colossus 3200 ltd. They were wired down to 1 ohm but after box rise they sat around 3.5 ohms so they were probably seeing around 1500 watts to the pair as I had my gains set far below clipping.

When I pulled them out after about 30 minutes of listening I noticed one of them had some voice coil rub. I hooked it up to my stereo in the house and on some different frequency sine waves, it is making some nasty slapping noises. I took a video to show you

What exactly could be the cause of this and is it fixable? Or should I just toss the sub.

Weird clicking noise coming from subwoofer - Subwoofers / Enclosures - SMD Forum

Actually I think I figured it out, it looks like the plastic base connected to the spider has become disconnected from the basket, or whatever its supposed to be attached to. The edges of the spider move freely up and down. Fixable?

Just glue the spider back down with some ca glue if it just came unglued from the basket.

1. They should not "sit at 3.5 ohms" if wired to one ohm. You had them wired to four ohms.

2. At four ohms (before rise even) on a Hifonics Colossus, they were not seeing 1500 watts.

3. From the way you describe it later, it seems fixable.

Nope, only pornography.

Like Mazdakid said, just use some CA glue to re-attach it.

They were definitely wired in parallel to 1ohm and at the amp, my dmm was reading 3.53 ohms while off.

I got some ca glue from.hobby lobby and some small clamps. Already glued it down, and for now I'll let it sit overnight. I'm worried the basket got in the way of some of the spots of the spider, but I got a lot of glue on it in as much space as I could so hopefully it sticks ,

Explain to me how they were wired to one ohm, but your DMM read 3.53 ohms

 

[Badseed]

Unless my dmm is broken, my explanation is this: it did.

I have 3 pairs of subwoofers all wired in parallel down to 1 ohm and the reading I get on all 3 of them is between 3.5-3.9 ohms on my dmm

This does not make sense mathematically, just saying.

Do you mean each sub reads 4 ohms, but together they are 1 ohm?

Six 4 ohm subs don't wire exactly to one ohm, no matter how you do it.

DMM leads have some resistance, but not that much.

Are you saying each pair is wired to one ohm, but the final load of six is between 3.5-3.9? If the three one ohm parallel pairs were wired in series, this would give you roughly 3 ohms. If you add in the DMM lead resistance, this is about right.

Im wiring each sub in parallel to 2 ohms and wiring them in parallel again at the amp for a 1 ohm load.

I'm just measuring the spear inputs at the amp when the subwoofers are connected. This is how the guy at my local shop showed me to do it, but that doesn't mean its right. I just took him at his word as I'd never tried to get an ohm reading before.

Ok, I'm just going to stop.

To answer your original question, yes it is fixable.

 

[Badseed]

Or you could tell me what it is that I'm doing wrong?

 

[adulbrich 5,000+ posts]

Measure the resistance of one sub.

When you put 2 identical coils or groups of coils in series, you add the resistance. Dual 2's in series equal 4 ohms.

When you put them in parallel, you divide by two. Dual 2's in parallel equal 1 ohm

With series/parallel, you can end up with the original load impedance.

If you put two pairs of dual 2's in parallel, then put each pair in series, you get 2 ohms

For 3's, it gets complicated and I'm too tired to explain it in-depth right now.

Touch the two probes of the dmm together. I bet it has resistance of 2.5ohm if it's reading 3.5ohm and your wired to 1ohm. Lol not rocket science

Never implied that it was. Just stated the way I was shown to do it, and stated that I wasn't sure if it was correct or not.
