Newbies Biamp question.


I'm considering to biamp my speakers. If I have a preamp that has two set of outputs, can I just feed them to poweramp and then send one output to the High and the other one to the Low binding post on my Speaker? Or I need other special equipments like active cross-over, etc. Then what if my preamp don't have two set of outputs can I achieve that with y-cable? Thanks for your help.

I kmow biamping can have it's benefits, but I have to ask. If you are new to this, why worry about biamping? I think you should just try to put together the best, simplist system you can. After all, you will probably be changing it shortly anyway. You will find system matching of equiptment and cables to be quite a task, if done correctly. You can always add an amp later if you must, but there are great systems out there that aren't biamped. It seems to me that you may end up losing money if you start out by biamping, unless you make very wise purchases, that you will be able to recoup.
Hi Blbloom: thanks for you suggestion. I forgot to tell you that I've been working out with my separate system for a while. I've been changing 4 multi-channel poweramps, 2 receivers, 1 processor, 4 pairs of speakers and 4 external DACs within 4 months period. I should have read you suggestion 4 months ago. Well I never try biamping, so I'm considered myself a newbie for biamping. I'm also doubt in performance of biamping (100watts x 2 each speaker) compare to 200 watts directly to each speaker. If anyone have this kind of experiment, please share your experience. Thanks a lot...
I've got to give all of you folks credit. We've got a great bunch of folks here who REALLY try hard to do their best ( and i like that ). Kudo's to all that "give a damn" and do what they can to help folks out.

I'd like to add some comments to those made above. Passive biamping should be done with two identical amps with ONE major catch. Even if your using two identical Super WamaJama 150's, those two "identical" amps can have different gain curves even though their input impedance and input sensitivities are similar. This is due to mass production and parts tolerance. As such, there really is NO way around this other than to have the two amps "gain matched". Since this typically requires electrical testing and circuit modifications, your better off going to active biamplification. This gives you variable output levels for each frequency range and DRASTICALLY increases the efficiency of the system. Since this has gotten even more expensive now and far more involved, Blbloom hit it right on the head. Concentrate on building the best "simple" system that you can initially. If getting fancy strikes your fancy, you can always do that at a later date. As mentioned, getting a basic system to perform optimally is quite a task in itself and reminds me of a motto that i use at work all the time: "Before investing in a lot of frosting, make sure that the cake tastes good first." After all, adding onto a system that isn't pleasing to start with doesn't make much sense and just gives you more places to go wrong. Sean

Hey Supakit. Thanks for your post. I guess you already know what I was talking about. I often learn lessons the hard way, too. Good luck.
Hi Sean,I guess biamping is "a piece of cake" huh? I'm frosted. I want my cake---.Life is short "eat your desert first". Never heard yours before ;but I like it.
