----Hi all there. I have Logitech Z2300 2.1 THX Speakers. I want to change the satellites that comes with it to floor standing speakers, is it possible?

Specs for Z2300:
Woofer: 120W RMS
Satellites: 40W x2 (total 80W)

Total Power output: 200W RMS


----Or is there any recommended speakers to connect?


----Plus how do you connect speaker wires to RCA? So that it can be plugged into the Z2300 woofer. (Z2300 woofer uses RCA plugs)




Thanks for the help! Cheers

What happened to the Logitech's speakers?

Short answer: don't do it

Long answer follows.

Theoretically yes it is possible (in the sense that it is possible to connect anything to anything else)

Also it is quite possible to drive floor standers with 20W per channel, some great sounding amps like the NAD have that much output.

Practically, these are the issues:

1. what is the impedance of the current satellites? the power draw depends on the impedance, until we know that it is not safe to hook up speakers to that amplifier. at best, it could sound bad, at worst there may not be enough power and fry the tweeters of the floor stander.

2. what is the high end extension of the subwoofer? will this overlap with the low end extension of the floor stander? will that produce boominess (bad)? how do you cut that frequency out from the sub?

3. Floor standers usually have good bass. is the low end extension of the floor standers lower than the subwoofer? Meaning, if the floor stander goes as low as 40 Hz, and the subwoofer bottoms out at 50Hz... why do you need a subwoofer, then?

4. "real" (not multimedia) subwoofers have a variable cut-off frequency which makes it easy to integrate and match with the other speakers; if the low end extension of the floor stander is, for example, 40Hz then the subwoofer should be cut off at 40Hz so there is no overlap. (see item #2)

5. lastly, the amplifier in the sub cabinet is not really all that good; a floor stander may be overkill for that application, and also the floorstander won't sound its best

not to mention the NAD amp outputs 20W continuously. the logitech 20W most probably is peak power only

sure can but ur floorstanding speakers may produce mid and hi sound only (not produce bass) cos Z2300 have crossover to protect the satellite speakers.

oh. thanks for the information. i'll still give it a try as theres no harm. since each satellite is able to produce 40W RMS, does that mean that it will produce 20W continuously? or able to drive a stand speaker at 20W?

Plus how do you check the impedance of my satellites?

thanks!

i went over about the crossover thing..but i still dont get whats a crossover for?...

Maybe it will help on the MID/High SQ but not much help for bass reproduction.
The built-in crossover will cut off lower bass frequency to the driver, even you conncet it to the FS speaker.
All the bass frequency will be directed to sub woofer which to me, not sound good for music, the bass produced not that natural compare to normal 2-channel setup.

You may try it out since only 2 normal wires will do the job, don't worry, the speaker/amp won't burn.
