Hindi b sir sobra yung hk990 kse sa specs nya up to 300w pag 4ohm? Masisira b speakers sir pag full vol sya? Sensya na sir kse dont know how omhs works on speaker-amp setup. Just basing my thinking sa numbers of the specs.
dodie,
if i may: any speaker will likely toast its voice coil if driven by any amp on full volume, either from being under-driven(too little power) or over( too much amp power)...the 4-8 ohm rating matching is not critical in your case. by the time you near the full volume mark, your ears are likely to give up first.
the 990s are reasonably powerful and should have sufficient power for your lsi9 (is this polk audio?)....the key point to remember is to have enough power, with enough headroom for those louder parts of the music you listen to. like a car, which is comfortable running 120 kph in the expressway, but has enough reserve for those moments you'd like to kick faster by a few moments so you can overtake a car in front of you...
cheers
