    hmmm...i didn't wanna wake the nordschows, so i thought i'd throw it to you guys. for some reason or another, i'm getting this really crappy distorted sound from my metro :( i have no clue what it could be...there are no tears in the cones, i can push on the speaker with no resistance, tellin me that _maybe_ there is nothing wrong with the voice coil...and what are the odds of both speakers being blown at the same time? BUT, i did notice that the bulb/fuse thingy on the ?crossover? was blown...so, does blown limiter bulb=crappy distorted tone? i hope that's the problem...those things only cost a buck or two. i really don't wanna chunk out 300 bucks for new speakers. that would suck.

    How have you got your gain, EQ and volume set?

    Hartke aluminum drivers in a Metro? Wouldn't that be a bit like putting a Ford engine in a Mercedes?

    on my profile...hey, munji, you already gave me crap for that, 'member? yeah, i put in a couple of hartke drivers (8 ohm drivers vice 4 ohm, like the stocker eden drivers) to see if it would work. i figured since the 4 ohmers drew more current, i could stick some 8 ohmers in there to make it a little less efficient to keep from distorting...that worked...but, come on! they're hartke drivers...what, munji said! so, will blown light bulb thingies yield a crappy distorted sound?

    to answer your question, munji, i leave the bass and treble controls flat with some boosted mids, and a little bit of tweeter in there...i put the volume to about 4 and the gain to about 3. now, the speakers sound fine for about 3 minutes, then it gets all crappy. weird, eh? i'm about to call eden, too, but don't let that stop anyone from replying...thanks
     
  7. Have you tried replacing the 12AX7 tube? Plus, when I got my metro I blew two sets of speakers because it was wired incorrectly at Eden. Once I called them and redid the wiring (with them on the phone) my amp works great!

    haven't tried replacing the tube...and my amp is about 5 years old, so i don't think they'll be replacing speakers for me :(

    Hmmm ... maybe the tube, but it might be that your speaker coils are heating up from too much power. Can they handle the output of the Metro? BTW, re: your settings. Is that 3 o'clock and 4 o'clock, or 3/10 and 4/10? If it's o'clock, you're really overdriving everything, and your amp will blow up soon ... well, at least the speakers.

    The bulb is there to protect your horn. If you're bulb is blown, the horn is not working because it's not getting any signal.

    Maybe you're trying to compensate for the lack of highs and causing the distortion that way.

    I'd also be checking the tube. A bad speaker won't take 3 minutes to show itself. 3 milliseconds would be more like it.

    hey, munji, that would be 3/10 and 4/10...i took my drivers to a speaker doctor and confirmed they were blown...i got some more bulbs and a couple of 12AX7's as well. if you guys ever need bulbs, just go to an auto parts store...those bulbs are the same thing as dome light bulbs (1 amp). same part number, same markings, everything. plus, you can get 2 for a buck. also, over the weekend, my two and a half year old decided to use my 2 eden drivers as a ladder to sneak some oreos, so even if they were good before, they are crap now. she put her foot straight through the cone material and tore the center dome out! munky! good grief. off to be reconed, i do believe :(

    anyone got some 10" eden drivers? or else, i suppose the hartke drivers are gonna have to go back in there :D
     
  14. How does a Metro sound with Hartke cones? Sounds like a bad idea to me

    I think the Eden guts hate you for putting those Hartke drivers in there. Cripe, this is 6 months old. Haven't you fixed it yet? Have David send you some XST drivers. now that would RULE!

    wow...where did this thread come from :confused: :D yeah, the xst drivers would rule, but i opted for original equipment and got the xlt's. the hartke drivers actually sounded pretty sweet...and i did check the old batteries. that was the second or third thing i looked at, but lo and behold, the voice coils were S-H-O-T. new cones...yeehaw

    Yes, blown bulb may equal bad sound.....depends how the bulb is wired.

    If the bulb is in series with the speaker that is after the crossover, you bet it can make bad sound.

    Unloaded, the crossover (if it is a coil and capacitor) acts like a short at its tuning frequency (series tuned circuit).
    So then the amp protects whenever it sees that short, but only at a narrow range of frequencies, so you might not realize what is up.

    I have seen this, and it was SOOOO confusing until I finally realized what was going on.


    Sounds like in your case the bulb was just telling you that you blew everything, though.
