Yeah sorry about the link forgot to put it in. Glad you found it, but it is possible just takes time and no rushing to get it finished, which can provide problems as you just wanr to hear the dam thing play.

Mostly Parts Express; they're generally the best option. They don't carry SB so I used Madisound's prices on those.

See this for an intro; generally LR4 or steeper at about 2kHz is desirable to avoid cone breakup and directivity problems on a six inch woofer. That's also about as low as most tweeters will comfortably go. Easier and often cheaper to throw down a few Sallen-Keys and a couple extra 3886s than to get the impedance matching right in a passive crossover. Another relatively low cost option's buying something like an Ashly XR-1001.

Won't improve the iPhone's DAC any, but that can be dealt with separately.

I havent really looked into them before, but it would certainly keep things simple, do they perform well? im a little skeptical of 'full range' drivers but that is probably just cause i never used a decent one before.
I haven't heard the CHR-70 drivers. I do have a pair of CSS wr125st drivers, and I think they are quite the performers.

The CSS fr125sr runs $49 each. The SDX7 runs $100 each. If you got 2 of each that would put you at $300 but you can cross them with a single inductor and cap and you wouldn't need a separate amp dedicated for bass (see here) or go active given your background.

The SDX7 will work in a sealed enclosure as small as 14 liters (A thread for Tysen and variations on FAST).

Its been a busy couple of days...

I have been looking at pasts express - good prices until i add shipping to Australia over US$90 to ship (about 100 aud) and i wanted to get everything for around AUD$200 so i need to work out what will be best for me ie import from us or buy local. The fr125s look pretty good.
Have you had much experience with visaton drivers? (i ask because i can get them locally for reasonable prices)
as for my existing crossovers im yet too have a close look at them to see what filter arangement they are - i belive they are 12dB but ill check them out.
