Center Channel Replacement for Logitech Z5500

[hanscau]

Hello, I was recently gifted a Logitech Z5500 with it's sub-woofer and front LR channel speaker. Understand that the system need the center channel speaker to sound good enough but can't really find a second hand center channel on sale. I'm thinking of just using a different center channel instead but not so sure what to look out for with the spec. Need help with knowing what to look out for.

Spec of speaker:

• Left/Right: 62 watts RMS x 2 (into 8 ohms, @ 1khz, @ 10% THD)
• Center: 69 watts RMS (into 8 ohms, @ 1kHz, @ 10% THD)
• Rear Left & Right: 62 watts RMS x 2 (into 8 ohms, @ 1kHz, @ 10% THD)
• Total Peak power: 1010 watts
• Maximum SPL: >115 dB
• Frequency response: 33 Hz - 20 kHz
• Amplifier: Ultra-linear, high-capacity analog
• Signal to noise ratio: >93.5 dB, typical 100
• Input impedance: 8,000 ohms

Does it mean I can use any speaker with an 8 ohms impedance? Or there is more to it than that. Also what happens if I use a speaker that have a larger wattage (like 120w) will it affect anything?
Much thanks

Hi,
It's not like AV receiver have much power to drive external centre channel speaker
Better to go with the same brand if possible .
You can test with other model centre if you can get from your nearest friends before to buy it.

Just read specs as -10W for LR ch 20 something watts for sub into 8 Ohms at 0.1% D
You can connect any speakers with 8 Ohms, Sensitivity above 89dB. Bigger the cone size, more mass of air moved , so anything between 4"-6" full range for LR ch
Don't pin your hopes too high as this 2.1 is made for a particular price point

I have an Z906 and Z2300 which uses similar drivers (speculated to be tang band)
my understanding is they are 69W or so. It is a flagship (in the computer speaker category)
the original drivers are crap and aimed at gamers rather than serious listening . Get a decent 2 way speaker and it will be a significant improvement - I am not using the stock satellites from my Z906 or Z2300. Ideally use it as a pure sub - the sattelite outputs are high passed, and the output from the built in amp isnt that great either

I have had my Z2300 driver almost catch fire during a party because it had a very powerful amp section from the Z2200 but they put a smaller sattelite to reduct costs. It overheated and melted, and eventually started to smoke. The pole piece was incredibly hot and and i burnt my fingers.
I ultimately got a set of Z2200 speakers, eventually used it as pure sub with an NAD 3020 and a philips hiq driver pair
