hellp peeps! my first post.
fu_man, they sure made very good suggestions. focals and dls are certainly a cut above the rest. but between those two i would prefer the latter.. i havent heard anything bad regarding their products, starting from their basic line to the deservingly acclaimed iridiums. un dls basic lng sulit ka na sa sql compared sa entry level ng ibang brands. my friend has it in his system, i auditioned it and after cguro ten seconds i asked him 'pare ano sub mo?' i was embarassed and surprised when he told me "wala." he just has the basic and stock rears ng altis! un low notes (bass guitar) tlga defined na defined and very clear (was listening to rock music not hiphop ha).. but of course that could just me the quality of the cd thats fooling me.
but since you are considering focals, u might also want to check the velocity vpc 172 series. 6.5" sya. i had it installed sa civic about a year ago and i am very satisfied sql-wise. it was featured in a magazine where it was compared to focals (sorry forgot which line) and the vpc produced better reviews. ive never been a fun of blaupunkt kc their too matinis for my liking. but this is their competition model and it sure didnt disappoint. if your listening to mellow music like light rock, pop/ballads, classical, this gives you the best bang for the buck (their best model THEN priced mid variant dls). lalo na sa live performances, ganda ng sound stage even the breatdth of the singer is very clear. so kung sql ka, consider this also. you'll be impressed. my 2c.
so its between dls magnesium or vpc for me.. sana nakatulong at gud luck hunting!
