So my driver side 6.5” started making some horrible noises the other day and when I pulled it to check it out I noticed the surround is separating from the cone. This will be the third time in the last 3 years that I’ve had a mid fail on me because of the surround coming apart. Each set of mids has been around 300$ so it’s not like I’m buying cheap stuff. The last set was a pair of hertz.

It seems like they just start coming apart at around the 1 year mark. Conveniently right after the warranties are up I might add!! Is this normal? Am I pushing them too hard? I’m tired off constantly having the replace mids and it’s getting expensive so I like to figure this out.

Yep, you're pushing them too hard. First of all, you should learn to listen for their distortion when they are reaching high excursion. Second of all, make sure you set a safe high pass filter for them, at the levels you must be listening at, go with 80-100hz to keep them from bottoming out.

I had them set at 100-2.5k so they shouldn’t of been going too low. I set my amps with a dmm, although I think i remember giving the mids a extra lil gain because they didn’t sound right.

Guess I just need to keep things turned down a lil bit. I honestly couldn’t hear any distortion from them but I always have my idmax pounding away so that’s probably making it hard to hear. I just found it strange every pair sounds and works great for about a year but sooner or later the surrounds give up.

How much power are you giving them?

200rms each. I have a jl xd600.6 on them now but it also happened when I was running my old 300/4 and they were only getting 75w rms. I know I’m running a lot more power now but honestly sound wise and how they perform there wasn’t a huge difference going from 75 to 200 watts.

I don’t think I’m clipping the head unit. It’s a pioneer deh80prs and I heard they’re good to pretty much max volume. Regardless I set my amps at 55 and never go over that. Usually listen at around 50.

Might try upping the crossover also, not sure if it will work well with me sub though.

I was just thinking, I listen to most my music streaming on Spotify and notice a lot of differences in loudness and quality. Could it just be some music is recorded louder and causes distortion? Like I can listen to like 50 songs in a row and everything is fine but then every once in a while a song will come on that distorts my speakers and I will have to turn it down or skip the song. This usually would happen on songs with lots of midbass.

I see your location is Spokane. Could this just be a matter of drivers not holding up to moisture in your doors, after exposure for over a year or so?

What were the other two brands?


Is environmental damage a possibility? Water intrusion on a speaker ill-suited? I had that issue recently and the surround was torn, amongst other horrors.


Audiofrog GS/GB are highly durable in doors and so is the Italian company Audio Development, based on my personal findings.


edit: Metanium beat me to it

Yeah I think this has a lot more to do w/ the physical environment rather than crossover points or RMS power. 6.5s are designed to run free-air, so generally the motor will bottom out before the suspension does. And the OP said the surrounds were separating rather than tearing.

Yes, moisture is the most obvious issue, but a year still seems like a short lifespan. Is there any kind of drip barrier behind/above the speaker to protect it from water (not moisture, but actual liquid water) inside the door? Are the weeping holes at the bottom of the doors clogged?

Do you know the slope of the crossover that you're using? You should be fine with a 100hz HPF, unless you have a really shallow slope. Have you ever taken a look at the cones while they are playing at high listening levels? A subwoofer can do a lot to mask the distortion, so it's important that you set your gains without any other speakers playing, you need to listen for distortion, and you also need to watch the cone to see how much excursion you're getting at the levels you like to listen at.

You're observations that going from 75-200 watts didn't change things much are correct, doubling power only gives you a maximum of 3dB more output, so going from 75-200 watts only gave you about 4dB at best more SPL, it's noticeable if you push them to their limits, but you should not have noticed a huge difference.

Some of the comments about environmental issues could be worth looking into, besides being separated from the surround, are the cones warped at all? Also, how are you mounting the mids to the door, do you have a solid, flat baffle that they are attached to?

There seems to be something causing premature failure, considering how many you've ruined so far. If all of them have failed the same way by having the cone separate from the surround, then I would suspect glue failure, or over excursion, maybe a combination of both. Over excursion would mean that you're pushing them too hard, so you'd need to find a safer HPF, or keep the volume lower. Glue failure could be a manufacture defect, but if you've tried different brands, and had the same issue, that seems unlikely. Has there been rust on the magnets, terminals, and tinsel leads of the failed woofers?

You guys get rain in Spokane every other hour. The last time I was there it was snowing too. I'm thinking the weather caused these speaker problems. Would you like to try some marine-rated speakers?

Honestly it only rains in the spring and fall for a little bit. It does come down hard for those couple weeks but the rest of the year is either freezing temps or hot as hell. There’s not much in between. Lol

I don’t think they are getting wet at all, I never see any evidence of water. Could the extreme temp differences effect the surrounds much? I mean my speakers were just basically frozen for the last 4-5 months and now this last month they’ve been baking In the car in 80-90 degree weather and it’s only going to get hotter.

I honestly don’t know the slope, I never changed anything on my deck. I just set all the crossovers and left everything flat, didn’t touch anything else. So whatever the 80prs default setting is would be what the slopes set at. I’m good at installing things but I’m completely clueless when it comes to tuning. This was my first active setup and I was just going to let someone else tune it but it sounded good to me flat so I just left it.

Also, here is how they are mounted. They appear very clean with no water damage or surface rust or anything. I’m not seeing weather damage anywhere unless just the drastic temp differences just make the surrounds brittle over time. It does take like a year typically for them to go out.
