Bi amping my ML SL3 speakers


Few questions for the ones that know the answers :)

If I’d like to bi-amp my speakers how do I know how much power should I send to the woofer and how much to the rest of the speaker ? (for mids and highs)

Currently I am using a Rotel 1582MKII and if I really crank the volume woofers start to distort so I’m thinking this amp is too much power ?

Info on ML site is misleading one place says 80-200 but I also saw 20-400 WPC so which one is it. My rotel amp is rated for 200WPC at 8 Ohms and no 4 ohm rating.....my speakers are 4 Ohms rated

Also I am guessing that the amp dedicated for lows doesn’t have to be as high end as the one for the electrostatic panels ?

 

Last but not least I will need a pre amp that has two sets of pre outs so I can feed same signal into both amps correct ? I really don’t want to get RCA splitters because that defeats the purpose of having a nice set of RCA’s - this question has been resolved thanks to riley804. I will get some but amp cables :)

 

Lots of questions any answers or wisdom is much appreciated !

Thanks for your feedback. Agreed panels can go as low as 1.5 Ohms

. I was hopping with that big toroidal transformers rotel can handle it but maybe not. Interestingly enough when I crank it its not the panel that is having an issue it's the subs, they bottom out....to answer your question.

They sounded like when you provided to much power to a subwoofer

Great this is really going to right way, one person says my amp is no good another says replace your speakers :)

I just really needed some help to understand some concepts which I kind of got so I do thank all of you for chiming in !

I already have a rotel amp that is overpowering the wiofers so I really think I would benefit from bi amping. Just need to figure out how to devide power between bass and mids/tweets ....

 

Would be nice to be able to use a crossover and drive the lows with specific power as opposed to full range. For the electrostatic panels I would like to get something nice might even go with tube so I can get the best sound out of my speakers 

Interesting read I know I shouldn't have gone down that road this is not car audio where I use to ran active crossovers as opposed to the passive ones that came with my 6.5" component set all the time for precise control and SQ results. 

So to get back to what really matters....do you guys recommend I get one amp for the woofers and another maybe class A or tube amp for the mids and highs.

 

Speaker posts in back encourage that since there is a dedicated pair of inputs for woofers and another one for the panel ?

Thanks guys seems like aftercreading the article provided by Mike I should try bi wiring with my 1582MKII Rotel amp see if sound improves....

Try not to jump on the what better train...there is always something better

I would like to make what I have work. If it fails for my ears or I see problems will make the necessary moves. I am open to amp change for now :)

I could. I am waiting for some alone time so I try different type of music see if distortion still there. Not in panic mode yet. I had the smaller version 1552MK2 and I was able to turn music on full blast no distortion thatsxwjen I realized I need more power.

Any idea why these speakersxare rated either 80-200 or 80-400WPC on various ML documentation. That is a significant difference !

 

I am not comfortable of taking on such a big project unfortunately.

My experience is that when I take something apart it never goes back the way and always end up with extra pieces. I will do some more testing and come back with some results!

That’s one way to look at it. It’s another one if you need to buy an amp that’s 200WPC or 400 :) You wallet will suddenly feel the weight 3db carries:)
