Sda srs amp questions

I am sorry if this has been asked before hand in other posts from the past years.

Im sure i would have my own answer if i took them apart but i have not yet :(. I know how i am and once i start taking things apart money starts coming out my pocket.

I have many many amplifiers at my disposal. But here is the question, if you had a 750 watt 2 channel amp would you run it direct to one the of binding post with the bridges on. Or would you remove the bridges and bi amp the speaker with say a 350 watt 2 channel amp.

I will test in the end my own way what sounds better but just curoius to ask what you guys are doing. My room is still in construction phase so testing is not for a lil bit. Probably spring time..

    If you bi-amp, you have to have a method of assuring that both amps have the same gain; or--at minimum--that the gain differences between the amps is pleasing to you.





    I would rather have one good amp per speaker, than two compromised ones.

    one amp has 2 channels 750 x2, feed each speaker left and right with 750'watts per side.

    Or i have 2 amps at 350x2 each amp will power one speaker removing the bridges and send 2 sets of speakers wire to each speaker totaling 700 watts to each speaker.

    No matter what each speaker will recieve 700 watts. Just curious if the Srs like the power to be seperated.

    None of the amps are compromised.

    Was never the best to explain or to read writing as i have always been a hands on person.



  • I think a bigger question is the quality of the power, not just the amount. What kind of amps are you talking about.
    All things being equal 1 amp on the MW's and one on the highs with jumpers removed should be a little better. In the real world you may or may not hear the difference.
    If con is the opposite of pro, is Congress the opposite of Progress?!

    The amps I'm talking about are in my signature not sure if it's comin up as I recently updated it.

    Amplifier watts cannot be added. Using the two smaller amplifiers as you describe will result in less voltage but potentially more current being available to the speakers. (All else being equal, and it rarely is.) IF (big IF) the big, 700-watt amplifier can supply sufficient current, you'll gain nothing by switching to two, lower-powered amplifiers but you'll lose the extra voltage so the speakers won't play as loud.

    Best course of action: Try it both ways, see which you like better.

    Pro amplifiers like the QSCs are not well-loved around here for home use. The concern is that they have massive power output, but aren't "refined". I can't say, I've never heard them--but the typically-low-price of "pro" amps concerns me. The PLD4.5 in your signature is only $2400 (or less) on Amazon, for a DSP-capable 2,250-watt continuous (8 ohms, 2 channels) amp that you wouldn't want to use for treble 'cause they're almost a dB down at 20K.
    http://qsc.com/products/Power_Amplifiers/Pld_Series/PLD4.5/

    http://www.amazon.com/QSC-PLD4-5-Multi-Channel-Processing-Amplifier/dp/B00EQJWZD6/ref=sr_1_1?ie=UTF8&qid=1422392234&sr=8-1&keywords=QSC+PLD4.5



    ARE THESE AMPS COMMON-GROUND? If not, you're going to need a Dreadnought if you use them on the 1.2TLs in your signature. The original version of the SRS is not Dreadnought-compatible, so you CANNOT use a non-common-ground amplifier unless you remove the SDA interconnect cable from the back of the two speakers.

    I'm not gonna get into a debate over consumer audio amplifiers vs professional audio amplifiers. I know the mc I have are amesome amplifiers but so are the qsc. Their is no way I would spend what Mcintosh wants now for the amplifiers they have.

    The mc amps I have gotten from family and the qsc I purchased myself.

    But I will say this consumer amps only can be used at home, they cannot take the abuse of what the professional amps go threw. Where as a pro amp can be used for both. Maybe a consumer amp does a very slightly better job at home. But not the thousand if not ten of thousands they charge for.

    In my opinion your better of spending a grand or two on room acoustics vs spending it on a mono block mck2w or a lesser model. Imaging needing 2 of these or more Chaaaa chinggggg! I'm assuming some people need to realize sooner or later your paying for name not performance.

    I would use the higher end Mac on them. That's all you'll need. Save my comments on the rest, but right tool for the right job would be my pleasure.

    We all have opinions I came hear to learn about the polk sda srs. I originay asked about if the srs like to see 2 sets of input instead of one. (Not sure how the crossover are setup).

    As far as amps and being ignorant I guess I'll stand my ground you do things your way I'll do things my way. I never was one to say my stuff sounds better or is better then anyone else's.

    Ooklaa,

    Dude, nobody is measuring banana's here. If you want to know what sounds good with your Polk speakers, we have guys with tons of experience with a variety of gear on those speaks. If you don't want to know or care then why ask the question ?

    Mcintosh is not the only company that makes amplifiers. You can get amazing performance from others as well. If you really want to get the best sound from the TL's, we can help. If you want to just get them to play loud, looks like you have your answer, so why ask the question?

    You pay for engineering R&D costs, wages, warranty costs, taxes, factory upkeep, parts inventory, dealer network profit, advertising, etc. Buying used usually halves that list price. You could go to a boutique amp builder that sells direct. Hopefully if you ever need service you can get it. Lots of advantages when buying a quality product with pedigree.

    WOW you guys are serious. Have fun buying your aesthetix or your krell or whatever you like. Their is a product for everyone. I know professional gear more cause well I toured for 10 years as a monitor engineer, as far as consumer gear I have limited knowledge on. I have been around all over and have seen and heard some expensive setups with 90 percent of having 6 figure budgets but none of them living up to hype the price the owners paid for.

    But if your telling me that a MC 1.2kw which goes for around 22,000 dollars sounds 20,000 dollars better then my 2,000 dollar qsc pld4.5 then I would say Bullcrap.

    I own older Mcintosh amps so I speak for them.

    You are nothing more than a troll! You JUST said "as far as consumer gear I have limited knowledge on". There are experienced people here trying to tell you something and you call BS.

    You are JUST like a lot of car audio guys I know. They, as you, think its all about WATTS. The higher the wattage the better the amp right?? lol

    Why ask for help if you will not listen to what people are saying. Hell hook your pro amps up and see what you think about them! lol

    Well, most of this forum is consumer gear. Pro audio and consumer grade audio are 2 different worlds.....provide different functions. We have many Mac lovers here as well.

    If your goal is to get your 1.2's to sound like your pro audio setup by pumping mega watts to them, ain't gonna happen my friend. If you want good sound however, listen to the guys who live and breath these speakers for 30 years.

    Following your logic, if one could even call it that, why aren't you using pro speakers at home? I mean those consumer speakers can only be slightly better and certainly not worth the money, right?

    You know, as a Mac fan and former monitor engineer I'm surprised you didn't know that the Grateful Dead toured with consumer Mac amps, the MC2300.....48 of them to be exact. What's that...oh snap!

    In the Sterophile forums there is an older thread about audiophile gear versus pro gear. Some of the things mentioned that stayed with me were...

    "Pro gear is built and marketed for dependability and reliability first despite rough handling and folks that may not know what they are doing hooking it up.

    Audiophile gear is built and marketed for its sound quality and appearance.

    There are differences in quality and price with pro gear.

    The audiophile makers through advertising conspire to get us to spend more money.

    A Crown pro amp will sound as good as a [ fill in the blank ] audiophile type amp."

    If you compare and think a Crown amp sounds better than your old Mac gear, more power to you. Some of us have compared and went with audiophile type amps.

    Not that old to be around the wall of sound. The mcintosh used where also personal preference and Mcintosh gave it all for free for what I have been told by my mentors for marketing purposes. I stated in my introduction as a new member of what I believe in as good sound. I'm not all about more power like some idiots start calling people names and other stating to bring a gun to a knife fight. Let's not start that cause I will break you real quick. Let's be gentlemen and some ladies maybe.

    Again I asked for bi amping the srs I did not ask what amp is better.

    Last time I checked (line array) JBL vertec won't fit in my house or yours. It's also doesn't have the style or design appeal people are looking for home audio. So thats how much you know about buddy.

    I grew up in car audio and that's how I ended up in the professional world.

    To be honest with you I'm sure the Mcintosh will sound somewhat better then the pro amps. But not at the pricing they demand.

    If you guys are spending 20,000 grand and up a amp more power to you. Don't Be mad that a 2,000 pro amp does just as good or maybe not as good to the stereoholics.

    What your ears hear and mine are different. Look at spec sheets and compare everything. What your room is like is different etc. but last time in checked my ears and my skills are what got me my job. I'm not on a forum board like a bunch of grumpy old men complaining and have no real professional skills in audio.

    I'll take the money savings and do other modifications.

    Also I don't mean to be rude to members who answered my original question thank you.

    Read the rest of your posts. They contain the attitude. What you fail to realize is that YOU asked the question. And did not like the answers. Simple as that. Take it or leave it. It is what it is. People that have owned SDA's for decades are trying to help you. So do what you want, try those amps out. You'll never know until you try right?
