Welcome to CP!

So, you're looking for info on rotel 1552 & 1582? I don't have any info off hand, but I would suggest typing those model numbers into Google.

Good luck!

been there done that. but that info didnt specify 4ohm capability. really want to know what will an amp do for a ht setup. does it make the system louder or increase speaker performance?

After quick jaunt over to Rotel's site, I looked at the specs, and neither of them lists specs for 4 ohms, which %99 of the time means they won't push 4 ohm loads...

Are you willing to look at used amps? What is your budget?

When I Googled that phrase, the first link was to the manual of said amplifiers on the Rotel website.

The manual said that both are 4 ohm capable.

The amplifier powers the speakers. jk.

does it make the system louder or increase speaker performance?

Louder compared to what? Increased performance compared to what?


Please provide some more detail, and we will be glad to continue assisting you.

An external power amp may allow you to play your speakers louder depending on the receiver you have. Some amplifier manufacturers list the power into
8,4 and 2 ohms. Most really good amps will produce more power as the ohms decrease. A speaker rated at 4ohms may actually dip to 2ohms depending on the frequency response being played.

don73 thanks for the info. i guess what im really hoping for is that an amp will add warmth and spaciousness to the speaker setup. is this what a good quality amp does? keep in mind i am new to this world of high end audio so forgive me if my ?s appear to be open ended.
