Hey I'm putting togeather a front stage at the moment using JBL Power Series Tweeters & GTO 4 and 6 1/6" mids but I need a 3 X-Over for them can n e 1 recomend a good set?

U.S audio makes a 3 way electronic x-over(picked mine up for $200 a year ago), as do PG the X406 which web audio direct sells for $508 or you could contact audioart(sponsors of CAA) and get a custom x-over made up.

yeah, are your wanting a passive crossover to power the speakers from a 2-channel amp?

or do you have 6-channels for a fully-active setup requiring an active 3-way xover?

or maybe 4 channels for a semi-active setup.

off-the-shelf passive xovers can be a bit hit and miss. the xover frequency points and 'flatness' at these points are dependent on many factors including speaker impedence, speaker sensitivity and resonance frequencies. so what may work for one set of speakers may not be so good for another.

a custom passive xovers would be nice, but if using high quality components, it can be expensive too. but a basic DIY one may be quite reasonable (at a guess, maybe under $100 in parts).

trying to achieve spectral balance (ie: nice even volume reproduction of midbass compared with midrange and treble, without one speaker dominating) may be tricky without adding in resistors.

maybe you could contact the JBL distributor (not sure who so ask a retailer maybe) for advice.

good luck
