xpr-7 or xpa-2

[manu]

hey bros.
i have xpa-5 now and want to expand my audio to 7.1 but little confuse should i choose xpa-2 or sell xpa-5 and buy xpr-7
any ideas how much it costs
i have polk rtia5(250watts max),csia6(200 watts max) and fxia4(125 watts max) surrounds

so please reply i'm waiting for ur reply

Well, we can't decide for you, but IMO, adding the XPA-2 for LR would be all you need. This said, maybe you WANT an XPR-7! I doubt you'd hear much difference, though.

Announced price is $1,999 for the XPR-7

[ausman]

upa-2/5/7 would suit the fxia4, I'd probably go the route of replacing fxia4 with csia6, then either buy xpr-7 or 7 upa-1's otherwise you'll have to replace the center and surrounds, use the xpa-5 to power the center and the surrounds and the xpa-2 to power the mains...

[manu]

thanks for ur replies brothers what i properly want to ask is i want to spend on amps so that i can have them for atleast ten years so for that much time xpa-2 and xpa-5 is good choice right but if i buy xpr-7 and sell xpa-5 it will be also for next ten years right

totally totally confuse and bro can't replace speakers now coz just a month ago i bought rti series of polk audio
so mmmm lets say if next year i bought higher end speakers with much power handling capacity in this point of view does xpa-2 and xpa-5 do justice or xpr-7

and bro are u sure xpr-7 is 1999$

[ausman]

the xpr7- has yet to be released, so the only options I would consider would be:

xpa-2 and xpa-5

7x xpa-1's

7x upa-1's or wait for the xpr-7 same power..

alternately you could go:

1x xpa-1
3x xpa-2's

Your telling him to get rid of some very good bipole/dipole surrounds and replace them with two center speakers? And your doing this because of a mfr's power rating?

There's a better chance of damaging those fxia4's driving them with a lower powered amp than a high one. Send them CLEAN power and forget about the rating.

I happen to own fxia4's and they are great with my XPA-5.

The UPA 1 is 200 watts so that would be 200 x 7 with seven of them. The XPR-7 is going to be 400 x 7 right? Pretty big difference in power there unless I'm wrong about the XPR-7 power ratings.

[ausman]

I was on the assumption the max rating of the speaker 125 watts, if that was the case then chances were the speakers would of sh** themselves on a 200-300 watt amp, as the max in 4 ohms would be 165-180 watts if that on the speakers, so I put forward a suggestion of upgrading the surrounds as most center speakers can also be used as surrounds as well,,

you'll notice that is the 8 ohms specification for the amp, 350 watts is the 4 ohms value..
you might get away with the fronts a bit long though the surrounds aren't rated for any of the xpa series and nor the upa-1... the option you can go with is either buy speakers rated for the amps or completely replace every speakers when you blow them.

[ausman]

according to what I heard was the xpr-7 was 200-350..

bro fxia4 is 125 at 8ohms so should i choose upa-2

[manu]

if i use 7 upa1's will i hear any sq difference than xpa-5 or i'm fine with upa-2 for rear surrounds or xpa-2 and xpa-5 or two upa1 for both fronts aaaaaaaaaaaw confuse confuse

"The ratings that were given at EmoFest were conservative as quoted from Big Dan:

"XPR-7: 350 watts RMS @ 8 ohms per channel, all channels driven
600 watts RMS @ 4 ohms per channel, all channels driven. Projected price $1999.00

XPR-5: 400 watts RMS @ 8 ohms per channel, all channels driven
800 watts RMS @ 4 ohms per channel, all channels driven. Projected price $1699.00

XPR-2: 600 watts RMS @ 8 ohms per channel, all channels driven
1200 watts RMS @ 4 ohms per channel, all channels driven. Projected price $1499.00

XPR-1:1000 watts RMS @ 8 ohms per channel, all channels driven
2000 watts RMS @ 4 ohms per channel, all channels. Projected price $1299.00"

Folks, stop confusing Manu already! Not everybody wants a stack of 7 UPA-1. IMO, both the XPA-5/XPA-2 combo or the XPR-7 are very good choices for $1,999. Unless you want to run your own open-air 100-seat cinema, the XPA's are good. It was hinted that XPR would not necessary sound better than XPA.

hey bro thanks for reply
can u please clarify my polk rtia5's have 250 watts max power so should i go for xpa-2 or two upa1 is there difference in sound signature of upa and xpa will two upa-1 sufficient for 250 watts power speaker at 8ohms
please reply i'm waiting

This is pretty easy choice, I think. If you enjoy simple stereo music, get the XPA-2. Use it for L/R and be happy.

If you want an all in one box, with tons of power and a light show, wait for the XPR-7; just recognize this amp was first pre-introduced a year ago and now it is part of a whole family of amps. My guess is its coming out quite soon but it is not here yet..... So XPA-2 is the easier immediate choice.

Also, there are tons of comments on this forum regarding powerful amps but just to restate. Too much amp power israrely a problem. In general, speakers blow diue to distorted power at clipping from underpowered or poorly protected amplifiers. The Pols mentioned above plus many other speakers will do fine with any of Emo's amps. I guess you could flat out overpower a speaker but you are more likely to destroy a speaker with bad, distorted power from a lesser amp.

thanks bro lets wait for xpr-7 when it comes then i decide right i'm not a stereo guy only movies and ps3

I haven't heard all the amps, but those who did said that the differences in SQ are very, very subtle. Look, even a UPA-7 would be adequate, better than 99% of AVR out there. XPA-5/XPA-2 is great. XPR-7? For very big power-hungry, unsensitive speakers (85dB is 10x more silent than 95dB). IMO, monoblocks really shine with stereo or multichannel audio (5.1 SuperAudio CD's). For HT, it's debatable.

If you start from scratch and want 7 channels in 1 box, the XPR-7 will be great. If you have the XPA-5, I think the XPA-2 would be the best option. But waiting for the XPR-7 can do no harm! If you have full control over the volume button! What if a kid turns it up to eleven behind your back? Your tweeters could be fried!

BTW, I don't know those Polks, others could enlighten you better.

That's not how amplifiers work.

I don't think his surrounds will ever see 125w going to them, and it's easier to blow a speaker with too little power than too much. He could connect XPA-1's (1000w RMS) to his 125w surrounds and I still highly doubt he would ever blow them in any realistic scenario.

[ausman]

you think a speaker that is designed with a max level of 125 watts wouldn't fail on a amp designed to to push 1,000 watts at a reference level, basically you are comparing a avr amp section to the power amp and the max rating to what the speaker will work at before failure..

if you feel safe connecting a 125 watt speaker to a 500-1,000 watt power amp that's your right to do so, though suggesting people follow your advice and do the same is your folly...

I've seen people do as you do and wonders why smoke is flowing from the speakers...

I would even suspect the limitations of the speakers the OP has to eventually fail given the the specs of the xpa line amps.. never mind pairing the current speakers with the xpr line amps...

[jeffakamax]

This is such a misconception. Wattage does not destroy speakers, distortion does! A 50 wpc amp that is clipping and distorting will take out a speaker much faster then an amp supplying clean power at 10x the wattage.

My rule of thumb for HT systems to have good dynamic headroom and avoid clipping/distortion is to amp speakers with 2 times their required wattage minimally.
