Italian speakers can you help me out?

Can any one help me - Are these speakers the same?

• I am tempted to buy a 2.1 sound system for my new led tv (i only have room for 2.1) I linked up my 5.1 system to the tv (using the headphone to aux and just the left and right speaker) and WOW its truley amazing ciompared to the built in speakers. When a gun fires to the left of the screen you hear it to the far left. When some one is talking in the middle of the screen it sounds like you have a centre speaker (i didnt have that one plugged in) MY 5.1 speakers are (logitech x-540) cost about £70-80 a few years back and the 2.1 im looking at cost around £45 and are Logitech z232. Will the 2.1 sound the same quality as the 5.1(with just the left and right speaker in)? with the sound positioning etc. Seeing as they are about half the price and for half the speakers. Here are the specs. if you can let me know Ill buy you all a drink :D Logitech 5.1 Product Features Frequency Directed Dual Driver (FDD2) technology produces a uniform soundfield anywhere in the room Create 5.1 surround sound from common 2-channel stereo sources with Matrix mode Satellite speaker stands rotate for easy wall mounting Dynamic, real-time bass equalisation maximizes bass response while minimizing distortion High excursion, ported, down-firing subwoofer displaces more air for deeper bass Master volume, subwoofer level and matrix button are all conveniently placed on the control centre Connect headphones to enjoy your games and music privately Technical Details Total RMS power: 70 watts RMS Satellites: 45 watts RMS (2 x 7.4W front, 15.4W center, 2 x 7.4W rear) Subwoofer: 25 watts RMS Total peak power: 140 watts Frequency response: 40Hz - 20kHz Drivers: Satellites: (2) 2" drivers per satellite Subwoofer: 5.25" ported driver Speaker dimensions (H x W x D): Satellites: 8.4" x 3.2" x 5" Center channel: 7.8" x 4.75" x 3.75" Subwoofer: 11.25" x 6.5" x 9.75"` Logitech 2.1 Product Features Product Type:2.1-channel PC multimedia speaker system Dimensions (WxDxH) / Weight Details:Right/left channel speaker : 8.6 cm x 13.4 cm x 20.3 cm Subwoofer : 15.2 cm x 18.3 cm x 22.1 cm Product Description: Logitech Z 323 - PC multimedia speaker system Product Type: 2.1-channel PC multimedia speaker system System Components: 2 speakers, subwoofer Speaker Type: Active Nominal Output Power (Total): 30 Watt Response Bandwidth: 55 - 20000 Hz Audio Amplifier: Integrated Connectivity Technology: Wired Speaker System Details: 2 x right/left channel speaker ¦ 1 x subwoofer Manufacturer Warranty: 2 years warranty Technical Details Main Specifications Product Description: Logitech Z 323 - PC multimedia speaker system Product Type: 2.1-channel PC multimedia speaker system System Components: 2 speakers, subwoofer Speaker Type: Active Nominal Output Power (Total): 30 Watt Response Bandwidth: 55 - 20000 Hz Audio Amplifier: Integrated Connectivity Technology: Wired Speaker System Details: 2 x right/left channel speaker ¦ 1 x subwoofer Manufacturer Warranty: 2 years warranty Extended Specifications once again ty

• Answer:

  Sounding good is all about the frequency range of the speaker. You gave a good spec list, but they only tell you a "so called" range. (55-20khz) What they are forgetting, or whats missing is the amount of power difference it takes to reachest the highest, and lowest values. Usually it would look like this 55-20khz +3db, or +6db. 3 is double the power it takes to reach that frequency, 6 is twice the power. Point is, without a power range, it could be 1 hz - 30khz the speakers could reach, we never know how much power they require to reach. anything below 3db is awesome, they will reach more frequencies better and respond close to perfect.
