I have purchased some MB Quart Q series drivers 6.5,4,tweet which i had to buy separately as they dont offer them as a 3 way set. I was planning to run these active off the 6 channels of my Davinci. Since purchasing them i decided to go back to uni and had to sell the davinci. My main question is should i buy or get built some 3 way crossovers to run them through or should i just wait and try to buy some more amps to run them actively? is there that much difference? Or should i just sell them and get a nice 2 way set with a crossover for half the price?
Go Passive!
Build some crossovers yourself. U'll be able to get a pretty decent response curve without much effort. It'll only cost like $100 in components, and then run it off a big 2 channel

if you wanna do it on a budget why not look at a Cadence 3 way active x-over/line driver. For budget i don't think you'll find to much that comes close. IMO.
www.cadencesound.comi know theres other brands, but you seem to be looking for a budget conscious solution. And i recon this should come in under $250 easy.

If not, Check the online store (Web Audio Direct) for some Hertz 3 way Pasive crossovers
And ill 2nd Bassaholic on his advice

keep the Davinci and go active...
note system design below
once you've got active you'll hear why

ok thanks for the advice i am still unsure which way i will go, i think i will probably end up selling the Quarts as i dont think i will be able to get good enough components on my budget to notice a difference

active is a total ***** to set up and get right but if done properly it can be damn good,
you can set the levels on each speaker perfectly!
but be warned, setting up my gf's 2 way active took about 3 months of me tweeking to get it right!

It's still easier to tune active than to build a 3-way passive to sound spot on.

setting up active is great, but i been playing around with my dynaudios lately and i found that using a crossover made it sound a little better as the crossovers had impendance compensation circuits ... but i used two crossovers so i dont know if it makes a difference ...
all the best but

Once you go to Active, you'll never go back.

Bit of a thread hijack here but I didn't want to start another Active VS Passive thread.
What do you think would be better for a relative newbie wanting to get into SQ competition? I was considering going active using Hertz Air Mille 6.5inch woofers with similar quality tweeters (don't know which yet) but I don't know if I'm capable of tuning it all that well. Equalisers scare me

"equalisers scare me" ..........
i know what you mean, all this kind of SQ stuff can get a little overwhelming to say the least hehehe

as a beginner, i would stick with passives as they are setup by factory trained professionals who know more about phase alignment and speaker matching than you or i will ever know
and even for the experienced, bear in mind - extreme high end home audio systems most often use passive networks, so that says something about thier suitability for natural sound quality.
besides that, active can be useful for un-usual speaker arrangements or mounting, where tweeter and mid etc are mounted away from each other, as the adjustability of the active networks allows you to tailor the respose more effectively.

The difficulty of designing passive filters depends on how accurately you want to produce the desired effect. At the easy end you can just solder a few components together from Jaycar. The most complicated involves solving laplace domain equations which requires university level maths and I don't recommend trying this.
