Which receiver are more suitable?

[louisgce]

how to choose a suitable receiver?

Hi ALL,

I'm newbie on this, really appreciate if someone can give me some advice.

Plan to get a set of speaker from Jamo, series C 803. On the spec sheet, there are something like this, but can't really figure out what it mean:

powerLongTerm 125
powerShortTerm 250

is it a number of Watt? if yes, what is the suitable receiver to power this pair of speaker? kind of confuse on this. Are there a 80W+80W output receiver are good enough?


Thanks

They are of low sensitivity. Unless your room is very small, you will need something that delivers about 100 watts into six ohms.

125 watts is the maximum continuous power they will take without frying and 250 watts is their maximum instantaneous power.

Like TLS said, 125 watts contimous power without damage, 250watts short duration burts. How big is the room you are putting this system into and how loud do you want it to go. Answering these two questions will give us an idea of the power you'll need to drive them.

Yes, plenty good enough. You won't use anywhere near 80 watts per channel in a normal home installation. Personally, my installation doesn't get beyond 20 watts per channel on the recording watt meter. The ratings on the speakers are maximums measured in watts. Applying more power than that to the speakers could damage them. You would damage your ears way before approaching those levels.

Those numbers are watts. Typically it means a sunstained signal level of 125 RMS allowing for peaks higher than that.

The speaker sensitivity is 87 which is average, meaning is will take a reasonable amount of power to drive loud.

Your speakers are also 6 ohm, normally most speakers are usually 8 ohms

80 RMS power should drive your speakers at a reasonable volume. However, if you like very loud music you might want to consider a higher power receiiver or different speakers.

The higher the sensitivty of a speaker the less power require to drive it , 100 db is very high effiecincy, 90 db is average, 80 db is very low efficieny, logrithmic). You also get more effective power deliverance ( less current) with an 8 ohm speaker as opposed to a 6 or 4 ohm speaker.


Is there a way that you can audition the speakers and the receiver you are considering? If you hook up the exact receiver and the exact pseakers and you can paly the volume as loud o ( or louder than you desire) then no problem!.

I intend to put the system in the living room that is not big. and I just need it to play the music in a comfortable level only.
I think my living room is about 20ft x 16ft.

Thanks for the great help.

 

[louisgce]

I'm not really looking for a loud speaker, I just need it to be in comfortable level. My living room is not big, it is just about 20ft x 16ft in length.

I just need a simple receiver that can make the speaker work thats all.

any suggestion for a good receiver under US$350?

How about this one for $399.75 free shipping.

http://www.amazon.com/Onkyo-TX-SR606-Channel-Theater-Receiver/dp/B0015S8PGW/ref=tag_stp_st_edpp_ttl

or for a little more go for the Onkyo TX-SR705, the Yamaha RX-V861, RX-V661 (under $300)

http://www.amazon.com/Yamaha-RX-V861BL-7-1-Channel-XM-Ready-Receiver/dp/B000PCEG58/ref=sr_1_2?ie=UTF8&s=electronics&qid=1216858540&sr=1-2

The 606 seems like a good deal but I don't like the fact that it does not have preouts so if you found out you need more power you cannot add an external amplifier.

All of the above are 7.1 multichannel receivers. I thought they are more cost effective. If you really only need a two channel one, then take a look of the Harman Kardon and NAD models. They will do well with your 6 ohm Jamo speakers.

PENG has made some very good recommendations

Louisgce, OP (Original Poster), PENG has made some very good recommendations for your system. The Yamaha and Onkyo are both very good receivers. The Onkyo's tend to be able to handle 4 ohm and 6 ohm (higher current) speakers very well.
