    Good Morning Everyone,

    I have an Eden WT 800C and I'm made my own cabinet with four Eminence CA1059s (the 8 ohm version). What is the most best method to wire the speakers? I've included a picture of the back of my amp to give a little more context. Thank you again.

    Sincerely,

    Darren

    Series-parallel is the most practical if you will be using the cabinet with any amp that can not support a 2 ohm load.

    If this is the only amp you will use it with, 2 ohms is the better option but be sure to clearly mark the cabinet as 2 ohm so that down the road it doesn't become an "amp killer"

    So please forgive my ignorance - it appears this amp can run at 2 ohms. What would be the benefit of running the cabinet at 2 ohms over 8?

    That amp delivers considerably more power into 2 ohms than into 8 ohms.

    The WT800C is a bridgeable stereo amp. 550 watts per side into 2 ohms, 1100 watts bridged into 4 ohms. 880 watts bridged into 8 ohms. Whether it's wise to have that much power for an 8 ohm cabinet with those drivers, I'm not sure, but the amp does produce more power bridged into 8 ohms than when running one side of the amp into 2 ohms.

    Being stable at 2Ω per channel means the amp is only safe into 4Ω when bridged. if the OP wants to use bridge mode then Series/Parallel for 8Ω is his only choice.

    Thinking about this more, you are probably better off wiring as 8 ohm in series-parallel so that you end up with an 8 ohm cabinet. Use the amp in bridge mode, just use good common sense. I forgot that this driver was changed from the original CA-10 which is quite a bit lower power (at low frequencies especially).

    Thank you so much - So the idea is if I run this as an 8 ohm cabinet. I'm sure it'll be fine volume-wise and if I want to run another cabinet there's less of a likelihood of something going wrong?

    Correct.

    That is a dual power-block amp - it has two power sections in it. Each Power channel can go down to 2 ohms and will put out 550-watts rms at 2 ohms. Each channel will run 300-watts into 8 ohms, 440-watts into 4 ohms, or 550-watts into 2 ohms. Or you can bridge that amp and it will deliver 1100-watts rms into 4 ohms. If you bridge it into an 8 ohm cab it will deliver 880-watts rms. The Eden WT800C is an extremely versatile amp!

    That's not quite right Paul. That amp will put out 300-watts into an 8 ohm load; 440-watts into a 4 ohm load, and 550 watts into a 2 ohm load. You are more than welcome to plug a 4 ohm cabinet in either side or even two into each side if you like. You just can't go below 2 ohms per side in that amp.

    It never hurt a solid-state (SS) power section to run a higher ohm load on it than it is rated for, it just delivers less power. Tube amps (all valve) can be hurt if you don't match the ohm selector on the amp to the ohms load you're subjecting it to, but it's no problem for SS power sections. Just don't subject it to a lower load than its minimum ohms rating.

    You can bridge that amp into an 8 ohm load if you like and it will deliver 880-watts into an 8 ohm load. It will bridge into a 4 ohm load with 1,100-watts. It can't bridge any lower than that because both power sections will be operating at 2 ohms to produce bridged power at 4 ohms.

    I have an older Eden amp that is 400 watts @ 4ohms per side and 800-watts bridged at 8 ohms. It can only bridge at 8 ohms because my individual channels only go down to 4 ohms and they are both operating at 4 ohms to come up with the 8 ohm bridged power.

    Please be so kind as to reread my post my friend. You are repeating pretty much what I posted. :)

    LOL...right on Paul! When I read that I thought you meant that you could only run a 4 ohm load on it when it was bridged and not run a 4 ohm on one side. Feeling a bit foolish now...

    Sorry about that bro!:thumbsup:

    Are we not human and prone to error?

    Oh no! Where did that come from? LOL
