The only thing I can add here to the otherwise excellent responses is that rears should be used mainly for ambience and are not meant to carry the load. Monitor size speakers should be adequate for this. TBH I have never heard a system that uses floorstanders as rears, so I can’t really justify my claims with experience
Is Full-size speakers for L-R Rears advisable?
I’m slowly upgrading my Stereo setup to HT.
Currently, I’ve full-size (FS) Tyler Acoustics Linbrook System II speakers for LR connected to Luxman M-900u Amplifier (150W @8 Ohm) & matching Center speaker (unused). To match sonically, I’m considering buying a pair of either bookshelf or similar/ better FS speakers from the same brand (Tyler Acoustic).
The questions I have are:
1.) Will a pair of FS rear eliminate the need for a dedicated Subwoofer or it would be better to get a dedicated Subwoofer & buy either a pair of bookshelf or FS speakers for Rears?
2.) If I get a dedicated Subwoofer, getting a FS speakers for rear will make any difference compared to Bookshelf speakers?
3.) Will I notice any positive difference if I buy more expensive fullsize pairs from Tyler & use them as Front LR & move the existing Linbrook System II pairs to Rear or it’s always better to keep the LRC with the same model/ series?
4.) Since they’ll be connected to a separate Amp anyways, does it matter if the Front & Rear speakers have different impedance (8 vs. 4 Ohms)?
5.) How should I drive the remaining 3 channels? Should I get 2 pairs of Stereo Amps (one will remain unused) or buy 3 Mono Amps?
6.) Does Amplifier’s Power Output wattage also have to exactly match for all the 5 channels or it can be close (+/- 50 Watts)?
7.) Do the Amps also have to be from the same brand?
