Couple questions about Yamaha RX-A3060

[Hasan Alnajdi]

If you want to know more about 9 and 11 channel so called immersive sound, the two articles linked below are good reads.

Your RX-A3060 has the latest DTS:X capability so you are good to go as soon as you get two more channels of amplification.

Wow!! Definitely a great reference! Thanks alot

I hope I am not being annoying but could you guys have a detailed read on speakers and how to choose them? As well as subwoofers.

 

[lovinthehd]

Lots of articles to read in general here http://www.audioholics.com/home-theater-setup

I think if you have no idea what speakers to choose you simply need to go audition as many as you can to get an idea of where your tastes lie; measurements can help. Subs are harder to audition as they're very room and setup dependent (and few showrooms have much choice in subs let alone properly setup IMO), I would chose mostly on specs. You might want to familiarize yourself with specs somewhat, this article might be a good start.

Budget range can determine choice to an extent also....

Dependin on the article from psb my speakers are 8 ohms and have a 90 efficiency (which I believe is the same as sensitivity). That is good in their ratings

The other speaker sure has more but beside loudness does clarity is effected by the other specs?

Not the same, efficiency is related to sensitivity but the better term when quoting the 90dB spec is sensitivity. 90dB and above are easier loads for an amp, which is a good thing.

Clarity is a subjective thing, what may be clarity to one may be brightness or even harshness to another, not everyone uses subjective terms uniformly....

I am confused my friend.. from my online search efficiency is measured as a percentage when sensitivity is measured in db.. now why would polk site refer to efficiency by db? Is it a typo or they mean some other kind of efficiency i didt get to notice?

Look for specs

 

[Hasan Alnajdi]

With powered subwoofers and other self-powered speakers, the power rating, whether FTC approved or WLS (When Lightening Strikes), doesn't really tell you much. Why? Because loudspeaker efficiency is by far the most important factor in determining how loud a system will play. Efficiency (a.k.a. sensitivity) is usually given as the amount of sound produced by 1 watt at a distance of 1 metre. A medium efficiency speaker rating would be around 87 dB from 1 watt at 1 metre. A highly efficient speaker might be 90 dB. Each 3dB increase in efficiency doubles the sound output for a given power input. So a 100-watt, 90 dB self-powered speaker and a 200-watt 87 dB unit would produce exactly the same sound output.

Try this article instead. http://www.audioholics.com/loudspeaker-design/loudspeaker-sensitivity

Polk marketing people, who knows....their engineers probably know the difference.

Its the same thing i read... The efficiency of a system is defined as the ratio between the useful delivered power output divided by the input power, denoted by the Greek letter small eta (η).

You're probably right, marketing ppl

 

[Hasan Alnajdi]

Can you believe i found only one lousy 140 watts two channel power amp in the entire country? Its completely ridiculous.. but i dont know if i should even consider it

 

[lovinthehd]

So what is it?

It looks like this one but i believe its an older version of it

Kind of a waste to use an integrated amp where you just need a power amp. Do you have music stores there that stock pro-style amps like Crown, Behringer, QSC, Crest, etc?

I never even heard about those brands not mention a store that sell them.. i only found two stores selling avrs and both have idiots of employees... with my little knowledge i understand more about devices than they do.. guess i need a trip to dubai

The pro amps are more used by musicians, studios, clubs and DJs (we have chains of such stores to supply this market here, like Guitar Center, Musician's Friend, Sweetwater etc) but have been used by home theater enthusiasts as well. Some really good amp values can be had; I have several Crown XLS amps myself, have used them both for powering various speakers with an avr or pre-amp as well as use them with my DIY subs. Behringer has a very good value amp in the A500 for example if you could get one (and can live with the aesthetics, it's more intended for rack installation in an equipment closet rather than on display in a living room).

OTOH maybe its time for a trip to Dubai

The AH site's definition is correct. It is quite often that people mix the two terms up but as long as they use the term dB/1W/1m or dB/2.83V/1m, you know it is sensitivity and not efficiency. Efficiency is typically expressed in % or in decimal number. For loudspeakers, expect efficiency to be very low, like less than 1%.

The site linked below has some good reads, including the efficiency vs sensitivity topics, and even a conversion formula/table:

Thanks you my friend.. its been helpful a lot

 

[Hasan Alnajdi]

Hey guys.. again

I found a store who sell power amps and he recommended Crown XLi 800
http://www.crownaudio.com/en/products/xli800

based on my setup do you guys recommend it?

 

[lovinthehd]

Yes, that's a good amp and even has rca connections and dual settings for sensitivity, fairly consumer friendly. Here on Amazon right now that one is $185 delivered, how much there?

ps Not sure about level of fan noise on that, so be aware.

here it's 85 K.D. after discount which is almost $280.. good thing you told me I will ask the seller about it
