sir,ok na rin yan for starter or stop gap measure for a better setup.
pero weakness mo yung small center sa home theater. maliit yung 10cs, try 10cm. importante sa movie dialogue ang center speaker, the larger woofer, the better.
yung av receiver mo, entry level lang yan kaya mahina ang power and worsened by the fact that wharfedale speakers are hard to drive and has low sensitivity. in other words, you cannot get the full potential of the wharfedale speakers.
kung gusto mo naman mas murang good quality sub, try mo marco pilyo sub (12k pesos) with amp4v2 by marco pilyo sa pasay. as to LCR speakers, maganda rin yung anthony audio philippians set sa paranaque/makati cinema square (same price as wharfes).
sa music setup mo: yung 10.2 BS medyo ngongo ang sound (muddy sound) sa mga entry level receiver but excellent when driven by integrated amps.pag my additional budget ka na, try integrated amp for a separate music setup or a tube amp like Sakura amp (5k pesos) modified by rene rivo.
anyway, just enjoy this setup and never listen to other's better setup. otherwise, mapapa upgrade ka ng di oras.hehe
