Amps and Speaker matching!

[anToNIcHeN]

Hey guys,
was just browsing thru amps and speakers made by different companies.... all the places i see that amps are more powerful than their respective speakers...
any reasons for that?
for eg...
SoundStream REF1600.2 (full range amp) has around 480 WRMS per channel, but no speakers match upto that rating?
or
am i missing something?

regards,
ant.

Full range amps like that are often also used to drive subwoofers.

relax these ratings are quite "flexible" :-)

true sir, i bought that crap called Audiobahn back in US, claiming 300 X 2 RMS in bridged mode.....i was under the same situation, so bought "matching" Audiobahn AS96Q speakers, having the largest magnet i cd ever see in a speaker....claiming to handle 200 W RMS; just to realize after returning back that my XPLOD sound better with my Silicon amp!!

True.... but then why not make it a monoamp... which has only limited frequency.... or is it that... its costly to build filters which would do the same?...

navin, these could be 'little' flexible.... but then again... 480 WRMS..... even if you take the half of it... say 240 watts.... still you dont find any speakers that match it....

A stereo amp stable at 2 ohms in stereo and 4 ohms in mono, for one, has far more flexibility in usage than a mono amp that would have been stable at 4 ohms.

B&T, but nowadays all the mono amps that you get are 2 or 4 ohm stable....

Also this is the amp rating
Sound Stream REF1600.2

No. OF CHANNELS: 2

OUTPUT (watts): RMS @ 4 Ohms : 480x2
RMS @ 2 Ohms : 800x2
RMS Bridged @ 4 Ohms : 1600 X 2
T.H.D:. < 0.02%
SIGNAL TO NOISE RATIO: 115dB
DAMPING FACTOR: 500
FREQUENCY RESPONSE: 10 - 70K
INPUT SENSITIVITY (VOLTS): 0.15 - 12.0
CROSSOVER SLOPE : 18dB

CROSSOVER FREQUENCY (Hz): 30 - 4k

Yeah Right!!! Those numbers are seriously questionable!!

Agreed. But can you do a tri-mode with a monoblock? There was my point.

Gunbir,when i was reaching out for my ICE i saw ss reference series amplifier in very high demand on ebay.com and bids used to be quite high for older & used ones.Sounstream may have gone down with their quality now.

[Autophile]

Soundstream is doing wonders if they are making amplifier with the specs mentioned . What price are they offering for this state of the art product?

O/T

Is this when the amp in question allows the subwoofer to be powered in Mono mode WHILE the speakers will play in stereo?
I remember reading something to that effect in the owners manual of my 2 channel US amp.

p.s : I know its not as simple as I have made it sound

yeah old is gold when it comes to many of the brands... most listings highlight the year, location of manufacture etc. Cant comment on the SS.

I am not pretty sure whether these are CEA compliant!... no where that I have seen mentions this!....
have any one out here used SS amps?

Also this is priced around $550 in the US

I would suggest to select any other brand and leave the SS as they not so good as they used to be.....
