    Okay--I just bought a Bergantino HT112 rated at 300w @ 8 ohm. I'm running it with an Eden WT500, which is rated at 600w @ 8 ohm. Obviously, thats too much power. So since the WT500 is bi-amped, I'm running one side to the Berg, but thats at 4 ohms now. I've been told this will ruin my equipment ( :eek: ) by some, and others that its fine--but I dont know a whole lot about this, why exactly would this ruin my equipment?? And is it really that big of an issue?

    You could bridge that head into that cabinet. I doubt 600 watts would hurt it. It would sound better with more headroom. Just dont put the master volume on 10.

    Running one side of the eden into an 8 ohm load will give you half the power that side would give you into a 4 ohm load.

    I'm not the amp master, but I think the only risk woud be underpowering your cabinet since it would only be getting about 250 watts per side into an 8 ohm load.

    I used to have that head & I always bridged it into my eden 210XLT with no issues.

    Yeah, I could mono-bridge it...but all that extra power gives it this hiss that just bothers the ****e outa me. I think I'm going to try it both ways and see what suits me--as long as I know I'm not seriously screwing my equipment up...the eden customer support said that doing that 4 to 8 thing would "ruin my equipment".

    i don't see the 4 to 8 thing???

    you have two options.

    run the eden bridge mono into the cab. Each side of the eden will "see" a 4 ohm load (1/2 of the 8 ohm load of the cabinet)

    run one side of the eden into the cab. that side will "see" an 8 ohm load. either way you're fine.

    Why don't you contact Eden and ask THEIR advice on your situation. It's always better to speak to the manufacturer about matters like your's. Say how do you like the Bergentino 112?

  6. I don't know the Eden heads but like IvanMike, I don't see the problem.

    First you want to tell us what the back of your amp says (can't find the specs on the web):
    - 600W 8 ohm is probably for bridge (WT-500? Manufacturer tend to market the biggest numbers...)
    - now it seems this is a dual channel amp. Like most dual channels, each channel drives its own load. Is it the case with Eden?
    - is this power rating RMS of Program? RMS is roughly an average (and is usually 1/2 of Program or vice-versa ie Program is 1.5x to 2x RMS). Again for marketing reason the numbers given may not be RMS.

    As suggested, you could also contact Eden and get their opinion.

    Well, not. Why do you think it's too much power? Unless you can play a sine wave (maybe feedback) chances are you would never hit greater than 300w RMS playing anyway.



    So since the WT500 is bi-amped, I'm running one side to the Berg, but thats at 4 ohms now.

    Are you saying that you are using more than 1 cab?



    I've been told this will ruin my equipment ( :eek: ) by some, and others that its fine--but I dont know a whole lot about this, why exactly would this ruin my equipment?? And is it really that big of an issue?

    Before anyone can give you a good answer please give us a picture (idea) of what your complete rig will look lie. 1 cab? 2 Cabs? 3? And their respective wattage and impedance ratings.

    Thanks!

    Joe.

    I'm running the Eden to only a Berg HT112 (by the way, ConeyIslandJoe, the Berg sounds really really great, it gives me the best tone I've heard from my rig so far...but that is of course in my opinion, if you can check one out I highly recommend it! I want one of their bigger ones now...someday...$$)

    <img src="http://img194.exs.cx/img194/9030/edenwt5009jl.jpg">

    Thats the deal with the Eden. So I'm trying to run it to the Bergantino HT112 which has two 1/4" inputs, two speakons and tweeter control. It only says on the back of the Berg that it is "300w/8ohms". If I only run one side to the berg, I think its underpowering it. If I bridge it mono...its getting this monster signal and a bit of a hiss.

    I talked to Eden customer support, and he said - "You cant mix impedances like that. You will ruin your equipment. I recommend you buy a speaker that suits your amplifier." (Damn Eden...always trying to make a sale, lol) I don't quite understand why this will ruin it, but I really dont know jack schlock about this sort of thing. I used the Berg at a gig tonight, and ran it monobridged--I'm just worried I'm going to "ruin" it like customer support said. Sounded fine. Compressor kicked in at about half power. Should I just quit worrying and farking enjoy it for once?!

    Yeah, definitely. Unless...you don't have to turn up very loud.

    Hiss is o.k. Just turn down the treble or the tweeter. That should take care of it. Remember, bedroom tone does not equal gig tone.



    I talked to Eden customer support, and he said - "You cant mix impedances like that.

    What the heck is he talking about? You are running one cab bridged mono at 8 ohms. Just like the specs say.



    You will ruin your equipment.

    What? How?



    I recommend you buy a speaker that suits your amplifier." (Damn Eden...always trying to make a sale, lol)

    Sounds like salesman BS to me.

    The Eden specs say that you can run an 8 ohm cab bridged mono, right? And your cab is 8 ohms, right? You are going through the right connectors, right? One cable from your amp bridged out to your speaker, right?



    Sounded fine. Compressor kicked in at about half power. Should I just quit worrying and farking enjoy it for once?!

    Unless there is more to this than you are saying (unknowingly) relax and enjoy your rig.
