14 watts is good enough for small room and personal use. I'm using M1335 30w RMS 14w + 2*8w. Shake shake bit bit if you crank up the volume. Enough to annoy your neighbour but not very sure though because my laptop has higher volume output compared to normal laptop (not very sure about this too but i compared it to few laptops of my friend) Something like 10% for IEM for normal listening volume and 30% for 32ohm headphone. For my M1335, i fix my laptop volume at 50%. Speaker volume goes between 50%~100%. 100% is my limit for the max volume I can go because I don't dare try 100% on both laptop and speaker. Maybe will destroy m1335 ==. Just my 2 cent. It's quite sufficient for a room. Bass doesn't sound really nice at lower volume but it did well at high volume. Never audit P3060 deeply but shouldn't be a bad one.

Another speaker i own is... M3400. Speaker volume 40%, Nokia N82 output with the song Boom boom pow, enough to vibrate my wooden window grill at my hometown, a size of living room of a double storey terrace house. Just "vibrate" cause I tested it last night, around 12am xD Maybe will try some time later and see how it vibrate my living room.  Just a RM160 speaker, I won't ask for too much but it's already too good for me at that price point. RM160 for 6.5" sub 18w+2*8w but it comes with mid range/tweeter and bass unit intead of just full range on my m1335. Produce better mid range and highs to my ear and also more bass. But... for RM250, you can go for higher end ones. Just try them out and you'll know it.
I read review about e3350 sometime ago and they seems to be complaining about its weight. The bass unit is too light to handle the vibration produced by the driver. I held it before and really... It's too light. I will think that it's more towards design than sound quality. Personal viewpoint xD Tried it long time ago. Not really like it for its price too. For the same price I'd rather get something like m3300 m3400 or the newer p3060. I have also audit P3060 some time back. For me i think it's like... ok ok la xD It has got usb input and better looking with the golden drivers. What you loss in that is the remote control which I think is important for me. Bass level can let it be fixed but I prefer to control volume in the speaker rather than on my computer so the volume knob must be accessible for me, especially if you're planning to put your subwoofer somewhere not that accessible. If I remembered correctly, both volume and bass knob of P3060 is at the back of the speaker which I dislike a lot.
Bla bla bla... Bored at home and answer something simple with something that long to waste my time xD

M3300SF is actually quite recommended by many reviewers. Try search for the keyword M3300 and you can see quite a lot of post on it in this thread. Not to mention... I FORGOT WHO IS HIM AGAIN... Who modded his M3300SF to the max. (Nismo? Cosef?? Forgot xD) Maybe you can try to get some review from them. M3300SF has more WATTSSS compared to P3060. My friend said his friend's M3300SF pawn his HCS2330 kaw kaw even though 2330 has more WATTAGE. Afterall... The figure doesn't really represent everything all the time. Of course... Don't compare those 300++W with those 30++W la... Then sure got difference.
Someone here also said ONE DAY OLD M3400(18W sub) bass can pawn M3300SF(30W sub) bass. I think it's just few page back. Try search for it.
haha... I never liked AL sound but heard ppl here said old AL sounds nice. For boom boom and clear sound, just look for something from edifier M/P series or S series but S series I think quite over budget (S330, lowest end for 400+-). HCS/C series produces better treble and mid but less bass. Best for you should be M series.
