What receiver/amplifer can I use to push M20?

sunnyskyhome

I am interested in knowing what receiver/amplifer I can use to push Polk M20?

Currently, I am using Yamaha HTR5920S to push a pair of M20 speakers and it seems to be okay when I listen to music but when I sing karaoke, the speakers seem not able to produce normal alt sound. Is this because the output of Yamaha HTR5920S (110 watt/channel at 6 ohm) is not large enought to push these speakers (20-150 watt/channel)?

If so, can you recommend some receivers to match M20 speakers?

Thank you very much in advance.

2- mice on a wheel can drive those speakers.Most use the M20 as a surround speaker.Nothing wrong with the yammie,just your singing abilities.

Thanks. I am not singing karaoke alone with M20 and a couple of friends also do. My wife is professional singer and everytime she sings in alt, the speakers become noisy that I feel like the speakers cannot stand the high frequency in alt sound.:mad: Compared to low or medium frequency singing, the high frequency singing is no longer soft and appeasing to ears. So that is why I am wondering whether it is the output of Yamaha receiver that has caused the problem.

The M20's are like a chevette, LSI's are like a Corvette. Same brand but very different performance. You should upgrade to RTi's, or LSI's They are more musical. You could be having problems with your Mic or mixing board.

My first question is: are you sure you aren't overloading the mic pre-amp? (or anything else in the chain? not necesssarily the power amp)

Second question is: how is the sound when you turn down the volume?

And note that those speakers are suited for modest home audio use. Not suitable for PA applications.

I am new in audio stuff. Would you suggest to use lsi25 for karaoke?

Digging up a 2 1/2 year old thread...... Using LSi 25's for karaoke is a pretty bold move unless you are going to use it for other stuff too. Like a good 2 channel setup or something. The LSi series is Polk's flagship, and there are many other choices for speakers for what you are looking for IMHO. That's a lot of coin to drop on drunken party singing, lol. Welcome to Club Polk.

Hi Jeff,

Thanks for the reply. I don't mean to use lsi25 solely for karaoke. I am thinking about getting lsi25 for music and HT as well. I am wondering if karaoke usage will damage the lsi25.

In order to bring out the best of lsi25, I heard that there is miminum spec requirment for avr Can you suggest the range of avr's that will work well with the lsi25 (from the low end budget of $700 and up).

Is there avr with feature that allow to switch the setup from HT to 2 channel on the fly without changing the cable hookups?

mr.bojangles

could it possibly be your microphone?

just taking a stab at it.
i have a karaoke machine too, and two mics. one is old but sounds clear. the other is new but sounds "hollow".

As for a "low budget" AVR for the LSi's, there are none, lol. In all seriousness, if you are going to get such nice speakers, you will need an equally as nice AVR. The price range you stated will get you a quality AVR, but you will need an external amp to really have your LSi's perform to their potential. Look into the Onkyo TX-SR 806/805, 706/705, 876, and their new NR series. The 700, and 800 series will work for you because they have pre-outs which are needed for adding an external amp. Also Denon, Pioneer (Elite and SC series) and HK make my short list. Every AVR has it's own sound, so if you can get your ears on them before purchasing, that would be a plus. The "problem" with the LSi series is that they are rated at 4 ohms, and most AVR's are rated at 8 ohms. While some can handle the 4 ohm load, they will not do it well, or for long before damaging your speakers or the AVR. The LSi's can handle a lot of power and are worth every penny, if powered properly. As for amps, check into Adcom, Sunfire, and Emotiva (ahh I said the E word, lol) 200+ watts will be a good place to start, but the more the better, IMHO. Hope this helps and any more questions feel free to ask.

I wouldn't suggest any of these for karoake. Get some crappy speakers that you don't care about blowing to pair up with the inferior microphones that come with these setups.

Thanks Jeff.

What is your personal opinion on Denon 4310CI? http://www.usa.denon.com/ProductDetails/4844.asp. The power spec indicates only 130 watts.

I do not understand the "pre-outs" and "external amp". Do you mean I need another amp in addition of avr?

Thanks,
John.

What is alt?

A small PA system would be a better fit as far as karaoke is concerned. Your local music store will carry them. If you don't have a local music store google Zzounds or Music 123.

Grrrr, I had one hell of a reply all typed out, hit post and the internet dumped on me. I'll try again, lol. That Denon is a beast!! They are usually pretty accurate with their power ratings and come highly recommended by many mebers here for their musicality. The term "external amp" refers to an external "power source" for your speakers. The term "pre-outs" refers to the connections on the back of your AVR that are required to run an external amp. The good news is, along with just about every other connection you could ever hope for or need, the 4310 has pre-outs, so you are good for an external amp. Brands to look into for amps would include Adcom, Rotel, Sunfire and Emotiva, in no specific order. The LSi's can handle pretty much as much power as you can throw at them and the amp will give them better/cleaner power than most AVR's on the market can. Also, with the speakers being 4 Ohm and your AVR being 8 Ohm, it wouldn't be impossible to run them with the Denon, but it would only be a matter of time before something went wrong and you damaged one or the other. 200 Watts or so will get you started, but is in no way a limit, those LSi's can hadle pretty much as much power as you can give them. Hope this helps, and good luck.
