I have a set of main/front speakers with specs of 20W to 150W
8 ohm, 35Hz - 22 KHz, 88dB.
Do I need to match these specs with the center i.e be exactly the same ?
or can i get away with a variance in any of the areas ie watts

Logically if you would have a 2 channel stereo system with different speakers left to right you would have no imaging, same rule applies to centre and front to rear. But in the real would this is not always possible, Good luck Re: Matching Center speaker with fronts 3Feb 22, 2011 9:12 pm Cozmo, What Barry has said is pretty much correct. Matching the voice coils is important if you can. It depends a little on th espeakers you have as to what will suit. What are the speakers you have now? What sort of speaker did you want? Re: Matching Center speaker with fronts 4Feb 23, 2011 8:50 am Yeah, what Matt said (and Barry). Matching the specs is not really where your focus should be, and if the speakers are of similar quality then that really shouldn't be an issue. Even if the speakers differ in their sensitivity or volume output that can easily be matched using the AV Receiver's configuration. You should try to ensure your centre covers near the same frequency range as the fronts, or at least performs close to the fronts until they get clearly below 80Hz, as below that point you can let the subwoofer take the load from any/all speakers if you want (many experts believe you should have all of your speakers set to 'small' in the AV Receiver, then all low frequency, below whatever crossover point you set, is redirected to the subwoofer). What you really want to do is to match their voice characteristics if you can so they sound the same (so when a sound pans from left, through the middle and then to the right it won't be obvious that they are different types/brands/make of speaker). In saying that, really good speakers should sound quite natural and not add any real colour of their own to the sound, so if you already have good fronts then an equally good centre, no matter the brand/make, should fit in quite comfortably. Re: Matching Center speaker with fronts 5Feb 23, 2011 2:23 pm What a great subject, speaker design is something I have been interested in for years. Adding to the above comments, the cubic capacity or enclosure size will affect the over all performance and output of the speaker including imaging. This affects SPL, Imaging, sensitivity, frequency and so on. This applies in front to back, left to right and centre imaging. If you have a Tannoy system 1000 on the left and a Tannoy system 800 on the right, can it image with each other? No it can’t yet it has the same tweeter. Also an Amplifier can not change the characteristics of a loud speaker yet it can change the performance in SPL, Imaging, accuracy and of course volume, that comes down to the performance of the amplifier not necessarily out put. An Interesting fact is if you double your amplifier out put the extra volume you get is only 3bd. As for the sub you are looking for a flat line response, it is recommended you role the sub in were your speaker finish, in this case 35hz, personally I would find that a bit boring so I would head up to about 50hz. The thing that will affect the performance of the system is the room and that a whole new conversation. Anyway I have dribbled on way to much, I’m sure everyone is ready for sleep now. I have included a site for you to have a read by none other Mr Floyd Toole, very good read http://www.theaudiocritic.com/back_issu ... c_28_r.pdf Re: Matching Center speaker with fronts 6Feb 24, 2011 7:17 am Thanks for your replies guys. As your answers suggest it is a very ambiguous subject this reproduction of sound subject and I guess people can spend far too much of their time and money trying to tweak their systems to achieve a "better sound" . Barry that link is gold! "Audio Engineering: Science in the Service of Art" the title sums it up really, as it will not matter how much science goes into it there will always be the perception of what is a great sounding speaker that is different for each and every person.
