hello sir ito naman tayo..LOL.. sir kung plano ninyo ang 3 way xover ang magdadala sa lahat drivers mo...so your planning as well to get an individual driver(tweeters , mid, woofer)? dahil if buy a 3 way components the manufacturer will not recommend removing the passive x-over coz these are pre-match and design to the drivers and it will void your warranty.. you need to remember may mumurahin na Active x-over at may mamahilan.. if would go sa mumurahin(cheap) na x-over hindi yan maganda magfilter..so more likely makakasira yan ng driver( so need to get or look into what kind of components they using in thier xover network) ..And by the way an active-xover alone will not amplify the frequencies this will just sort out the signal what goes in to your specific drivers. it is best to get the active-xover and has the line driver feature.. and if heard a set-up based on one installer only you need to go out and seek for more.. dyan ka makakuha kung anong ideal system na gusto mo..

Sir, trust me these are not just thoughts..this is based on experience and lots of trial and errors.. Either way its your choice.. Im just sharing..
