Replacing Logitech z2300 speakers!

[artazzzzzz]

Hello, at first I want to say that I am very very new to music equipment!


Yesterday my Logitech Z2300 satellites blown and I am thinking of replacing them (subwoofer stays). So I have 2 questions:
1. What satellites do you recommend for Logitech Z2300 subwoofer (price range 50-80$)?
2. Does subwoofer have an amplifier inside or I need a new one?
I tried to surf and found these, http://www.amazon.com/Sony-SS-B1000-.../dp/B000OG88KY. Are they gonna suit?
3. A new good amplifier would increase my sound quality or power?

Thanks for your answers!

1 - most bookshelf speakers will do - I wouldn't look at more than a 4" midbass, as you have a sub for bass.
2 - yes, the subwoofer has an internal amp for the satellites.
3 - A new amp may well increase maximum volume available, but it would get messy as you'd have to re-adjust the volume of the sub every time you changed the volume of the bookshelf speakers.

Thanks for your reply!
So I dont really need a new amp. But I cant decide what speakers to buy then. Logitech z2300 sub has only RCA outputs so I would change cables to most of the speakers. Any advice what to buy? Sub is only 120 watts power.

You say only. I run my sub on 50W, and I can get furnature visibly vibrating. The sub also gives 40W per channel to the satellites. Dependant on where you are, I'd try (as I said before) something with a smallish woofer, maybe 4". You won't need anything more than this as they will be crossed over.

If you got some RCA plugs, then soldered speaker wire to the connections, you'll be able to connect anything you want, which is a nice prospect.

I don't really care about where I am I can listen music to the max sound. Also, what is crossover? And how to know is ur sub giving W per channel?

The specifications for power are on the ligitech website.

A crossover is a filter to stop low frequencies going to the tweeter (and cooking it) and high frequencies to the subwoofer (which would muddy them)

In the Z2300, the crossover would be around 120Hz. This would be where the amplifier begins to stop sending signals to the satellites, and starts sending signals to the subwoofer instead.

Okey Chris, thank you for the useful info! I think I have decided now

okey I am lost a bit what RMS should be on the speakers? If I buy speakers with same rms as sub has it will limit the sound loudness?

[chris661]

I wouldn't worry about it too much. Typical bookshelf speakers take 50wRMS (would mean 100W peak, without damage) and they'll be fine.

The sub is --meant-- to give 80w per satellite, and 120w to the woofer, but these ratings are well into distortion, to a point where it becomes unlistenable, so the ratings mean little.
You'd be surprised at how little power it takes to get a decent amount of sound, then how much power it takes to get a little more.

Hey again
Are you sure sub gives 80W/channel? I Googled it and found that it gives only 40W. Z2300 speakers were 40W and they were unlistenable at ~60% volume. What rms speakers must have to listen on ~80-90% volume? Or this thing depends on the speakers quality?
