J&M 7.25 speaker problem - blown?

I noticed today that it looks like the cone part of my right hand speaker is flattened. Its also staticy and almost sounds blown any point over half volume. I checked with several CDs, thinking it might just be a bad burned disc, but it happened on all of them. It was fine and the cone was never messed up before,.. but have noticed it in the past couple of rides it looks like its getting flatter. The static noise just started today. Doesnt make any sense because the grill is intact. The only thing I have done recently, was add the J&M amp. I plan to contact J&M about it, but wondered if anyone else has had any problems with their 7.25's yet. Its a bummer and I hope I don't have to send it in and wait for them to send me a replacement. Im so used to kick ass sounding speakers now, I could never go back to stock ever.






For a wounded man shall say to his assailant,
'If I live, I will kill you. If I die, You are forgiven.'
Such is the rule of honor.

I had it happen to one of my speakers as well. I contacted John at J&M and had to send it in for evaluation. Five days later a new speaker showed up.

I was just hoping it was a fluke, but now that I see you are having problems I just wonder how long my remaining original speaker will last. I am running an ELF 2125 amp (same as an ARC and J&M).

I had my doubts about running these with an amp as they do not look that robust, maybe they just had a bad batch.

that's a drag... hope you get a new set without too much trouble.

I'm seriously considering getting an elf amp for more lows.

the guy who sells elf amps, had said he tried the 7.25 J&M's, (he owns a road glide) and ended up with infinity kappa 6.5 and also mentioned polk audio db 6.5 speakers as a lower cost option, both sounding better than J&M...

not sure of the part no, and as far as I know those are both 4 ohm speaker, still looking for the 2ohm part no.'s.

the adaptor rings are around $40, which seems high, but, whatcha gonna do othwise?

Don't get me wrong, the 7.25 speakers sound fine on the bike. I had some Polk audio db 5.25" before the J&M's and the J&M's sound better at highway speed.

I think it is hard to judge the speakers with a static test, I don't think the 7.25" sound all that great in my garage but they do shine on the road. While my polk speakers rocked the house when in the garage, but had no balls doing 80mph.

The only issue I had with J&M was they only wanted the bad speaker back, I would have much rather exchanged the pair for a new set. Now I am doing a waiting game to see if the other one craps out.

Yeah, I think it is hit or miss with all speakers. I had the hogtunes on my 05 and one crapped out after a couple of months with just the stock unit. They replaced it immediately and all was fine. J&M seems to be a stand-up company and I doubt you will get any hassle replacing it.

I will say, I had POLKs on my 05 for over a year (pre hogtunes) and never had an issue, they just didn't do it for me sound-wise but I didn't have an amp. Keep us informed of the outcome, cause I would bet a good majority of us have your same set-up.

This is no joke, mine crapped out on the way home from Sturgis with about 1200 miles left to get home.

I don't know if it helps, but when I changed out my speakers, I went with the ones made my Kicker. They sound great and carry a little more bass than the 5.25 J&M's. I've had them since the end of May, and almost 8000 miles later they haven't missed a beat. I've had the Hogtunes tweeter pod, and no problems there either. Maybe I've just been lucky, but I'll advise if they screw up. And a buddy of mine just went with the Boom spearks from the MOCO. I'll let y'all know how they turn out too

sorry for your loss of your speakers Chain...that sucks the big one. Mine are still rocking (touch wood) but on the stock HD unit with out an amp. (hope i didn't jinx myself there) I don't know how speakers flatten on their own? Is that possible? or did someone say, "wow what a great looking speaker with a shiny dome thingy, I wonder if I can touch it with my key? or other skinny object?" seems a bit strange doesn't it.

I am sure John at J&M will fix you up good...tell him who you are and who your friends are here....he'll get the picture
