I wonder if anyone can tell me what bi wired is?I see it being mentioned on the threads if it is something that should be done?
:confused:

    there are alot of searches you can do regarding bi-wire&amping. Many are very funny and will put you into hysterics.

    Since I'm the only one sober around here....

    Bi-wiring is simply adding a second set of wires (or a special bi-wire cable) to your speakers and removing the metal straps that connect the binding posts together. Failure to do so will cause serious damage. (Check your manuals for a better/more technical explaination.)

    Some people feel that there is an increase in sound quality. Another one of those try it and see if it sounds good to you kinda things!

    Yep. It looks kinda like this... :)

    In most cases, the top set of wires sends power to the top half of the spectrum (mids/highs) and the bottom set of wires sends power to the low end (subs, or drivers crossed over on the low end).

    I could be wrong, but I think the principle behind it is seperating the signal/power before it enters the crossover so the crossover has to do less work? *shrug* I dunno....

    Phuz crushed this answer............nice photo quality too! That is exactly the reason to bi-wire - to bypass part of the crossover and send a supposedly less processed or "purer" signal to each speaker.

    Yes,
    In a nutshell.Bi wirng is it's simplest form is just that 4 conductors from a single amp out.Speakr is hooked up like the pic.One pair top posts and the other pair bottom post.

    I have found bi wiring to make a great difference.Clear high's,punchier and tigher mid range and the bass seems more controled.I never heard it make the sound worse.
    It's a good technic for one looking for a good relatively cheap upgrade.(depends on what wire you buy to support cheap or affordable,bi wire cables can break the bank).

    Good for you Dan, we are all impressed. Now if you were to take your RT1000's and perform Ken's biwiring test side by side with the LSi's you would understand why we said you couldn't biwire them.

    BTW, I am curious about one thing though. Before you got your LSi's, it seemed that all you could do was rave about the Dynaudio's and B&K (allday). The search was over, that was the perfect setup. I'm curious what prompted the purchase of the LSi's? If I remember correctly, the demo or two that you had was pretty lackluster.....Don't get me wrong, I think it's cool that got them, I'm just wondering why.

    Tiger,

    The principle behind it is this: In a two way design, at a certain point the crossover essentially crosses the signal over from the mid/bass side to the tweeter side. The theory with biwiring (biamping works on the same principle) is that you have a set of binding posts for each side allowing you to power them independently.

    Having said that, I think if it is offered as an option on your speakers, you should try it. How much actual benefit there is, is a subject to debate.

    Troy,
    I feel good about how I wired the rt1000p's right, wrong,ghetto,whatever term you want to call it...It was speaker level to both binding posts,I got a sonic tonal improvement and that was enough for me......I really don't want to open that can of worms again.....I'll just say it sounded better and that the goal of any upgrade isn't it.??????can we agree with at?I'll leave the TERM out of this to save another pissing match over wiring.

    The Question you asked about why I went Lsi over Dynaudio ...well there are alot of reasons......I will tell you a couple of them.Before I get started.....B&K is always a fine choice for alomst any system.they make wonerfull products and give you a ton for your money..........Rotel won my heart in sound quality only.I feel Rotel has a much cleaner more dynamic sound then B&K....Not to take anything away from B&K,I feel there pre amps smoke Rotels for inputs,features,etc......but they lack that ever last bit of purity I desire...I'm willing to sacrfice inputs and features for sonic purity........

    Now the Dynaudio and Lsi thing...........I went back and forth..yes you are correct with my demo's on Lsi.......the Dynaudio had Rotel runing it most of the time,B&K,and Mart levinston....then Pioneer Eltie vsx49tx......At Soundex where I used to work before I desided to return to Tweeter.The Lsi 15's had Yamaha rxv1,Pioneer Elite vsx47tx running them where I demo'd.The room sucked **** as well.But They did catch my attention when I started to run Lorenna Mckennitt.Man the female voice choked me up inside.......They moved me.....The dynaudio Audience 72's would be a perfect vs battle for the lsi 15's...the Audience 82's might have the last word in detail and bass responce.....close....The Lsi15's I desided to bring home for the ultimate demo ....after hearing them crap out my Denon avr3801,I went to the Stereo Exchange as I wanted to test Rotel on them as I have Installed Rotel so many times for Soundex and was WOWed everysingle time....Match made in heaven..........not at first......when I first hooked it up.....I said o **** what have I done...it sounds like hell,then the amp warmed up and look out...dude I was so Impressed with the sound,I just knew at that moment that this was what I was searching for.....This is the short version by the way.

    I wasn't looking for just 2 channel speaker but a home theater package......the Audience line doesn't offer a Bi poalr/DI polar type speaker, the Lsi 's do....and I so loved my fx/500's,they are on e bad **** speaker.I listened to the Lsi/fx's and they just blew me away.....god the Lsi line is good.......I'm completely got them in my SOLE...........I'm all about them.Even picky **** liv4fam listened to the Rotel/Lsi combo and said WOW/Damn there good.......he normally beats everything up, but he was hard pressed to do so.He even felt they destroyed his new Def Tech's and B&K setup,which we both agree is a fantastic sounding system.....
    I feel all you guys should one day own Lsi.....what a achivement from Polk........my hat is off and I'm kneeling on one knee.......

    'when I first hooked it up.....I said o **** what have I done...it sounds like hell,then the amp warmed up and look out'

    That much difference, from 'hell' to 'look out' on a cold vs warm Rotel (ss)?

    'Even picky **** liv4fam listened to the Rotel/Lsi combo and said WOW/Damn there good.......he normally beats everything up, but he was hard pressed to do so'

    Well, thats just funny in and of itself, and I imagine is pretty much on-target...

    Cheers,

    OK help me out here guys... Is Rotel a tube amp or something? I did not think so but what the hell do I know anyway. If there are no tubes then what needs warmed up? its solid state right... For me I figure the power supply caps take a few msec to charge and thats it???

    Confused is the HBomb

    No you aren't missing anything HBomb, it's a solid state amp. It must be some special cap that Rotel has. Either that or Dan had too much of that special tea....

    I'm just saying as things warm up the noise floor of solid state devices will increase hence the reason for huge heat syncs and fans....

    OK, so lay it out for me. Just what is it in a SS amp that needs to warm up? Do tell.......

    I have to agree with Mantis, to a degree.

    <choke, sob>

    I can definitely hear a difference in my sand amps after they've warmed up. It takes a couple of hours to get most of the way there. So, I leave 'em on 24x7 [unless we're expecting a lightning storm].

    Unfortunately, I can't explain it. A friend of mine, who builds high-end gear [Bob Crump, of CTC Builders and ParaSound], explains that on SS gear with multiple output transistors, the bias current on each one varies a bit until thermal stability is reached.

    I can't say that the sound goes from hell to heaven, or whatever, but there's an audible change.

    I dunno, I've never listened for it to be honest but I will say I've never really honestly experienced it and certainly not to the extent where it would make a drastic change in sound quality.

    I'm not saying there isn't something to it but I'm a little skeptical.

    Hey, there is nothing wrong with agreeing with Dan, it just makes for good fun when you don't.

    mantis, I'm not being sarcastic in any way at all. It just seems counter intuitive to me for warmup time on solid state.

    Example, does a computer work faster after its been on for a while? I don't think so but would be the same analogy... would it not? you guys have a hell of a lot more experience than me and I'm just trying to figure this whole thing out.

    I think it's a matter of voltage regulation among the caps and such. More than likely there is a variation of voltage until the parts come to a "normal operating temp". Just like computer parts are tested at temperatures, they have a "normal operating temp" that they work better at (CPU is included, as if it gets too cold, things happen too slow... even though that's wayyyy down there).

    Hey Tiger ,
    I know your relatively new to the forum, don't mind the fellas arguing and sniping, to most of us it is in fun...........One thing I thought I might mention is that you don't have to go out and spend a fortune on special cables to bi-wire, you can use just 2 sets of speaker wires to accomplish the relatively the same thing, and somthing else I am not seeing is that both cables will originate from the same posts on your amp. Good Luck
