Okay so I've done some major research in the past 2 weeks since first discovering this site, and I've learned alot. But there is one way to really learn how to do stuff and that is to just do it. So I'm gonna start cheap with some drivers that I won't cry over when they break but can still yield some satisfactory results. What I'd like to do is start of my diying with a simple 2way stereo setup consisting of a driver that goes pretty low, so as not to need a sub, and a tweeter that can cross the mid at 3Khz or so. My budget for this "starter set" of speakers will be very limited so I have cash left for actually building my real HT setup once I get felling better about my speaker building skills. I'm looking to spend about $100 total, so the way I figure I have maybe $60 to spend on speakers. Can someone recomend a quality woofer and tweater that fits the bill? A speaker combo that has been used often is also good so I will have acess to some crossover diagrams as I have never done them before either. Thanks to all who take time to help 
I forgot to mention that I would like to use these drivers in a ported setup, the amp I have is an old kenwood 100x2 stereo amp, but these speaker by no means have to handle that.
One setup I was looking at was:
woofer: 2x dayton reference
http://www.partsexpress.com/pe/pshowdetl.cfm?&PartNumber=295-362&DID=7
tweeter: 2x HI VI TN28
http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=297-409
will these work well together?

$30 per channel on drivers is really low, but not impossible. If you build something, it is no more trouble to build it right so you needn't think in terms of throwaway test units - build a pair of keepers.
If you would consider increasing the budget a bit, I offer the following for your consideration.

Of course there are loads of other possibilities.

That RS-150S 6" speaker you chose will probably need a 3rd or 4th order crossover to get past that cone breakup starting at 5K...
The SPL matches the tweeter .
The box is small - .4 cu. ft. or 11.5 Liters..
If you could wait a while the guys at Madisound or Parts Express or busily building speakers with that woofer...

RJ are you saying to email those guys with a question and they may design a crossover suitable for the woofer? Would I still need perhaps a 4th order crossover if I plan on crossing the woofer at 3Khz?
Bill that adire link looks interesting, but what can be said about the sq? I'm a little worried about the quality of drivers used in the project, sure the response is flat, but as I've heard this isn't all it take for a good sounding speaker.
Are there any other projects like that with perhaps slightly better drivers that can easily be reproduced? And lastly is there a good program you all use to help calculate crossovers for certain drivers, or what does it take to know what kind of a crossover will work well with a certain driver?

I realise that my first post wasnt very helpful.
No what he means is that in time someone will come up with a design that you could use.
Yes, crossovers are not instant and roll off at various rates. If the resonance is at 6khz using a 1st order will have the 6k peak down by 6dB. This isnt very much. A fourth order network has it down 24dB which is much better. Steep slopes with notch filters are required to tame resonance peaks associated with metal cones.
Yes there are many kits available that use better quality drivers which can be easily made.
Speaker workshop by adua is the only free simulating program out there so maybe you should have a go with that. You will need to use SPL trace to copy the response of the drivers from picture files.
What it takes is knowledge learnt over time.

The Dayton RS Drivers just came out late last month. Theres not enough speakers built yet to come up with a solid design. There are advanced DIY'ers that are building speakers with these drivers right now.
I'm following xgecko on Parts Express Tech Talk and his project.
I want to know how the BG Planar/Ribbon tweeter matchs up with these aluminum drivers.
My idea was to use 2 8" RS drivers and 1 BG Planar/Ribbon in a tower speaker. Like the Dayton 8's--- http://www.wadsnet.com/~dtenney/dayton_8MTM.htm
There's a bunch of free speaker design software here;
http://www.pvconsultants.com/audio/frdarticles.htm
You'll need Microsoft Excel Spreadsheet program to use most of them..
Hope This Helps ---- rj
p.s. If you need more help keep asking....

So whats the chance that a person who has never done a crossover before can start of on a complicated looking 4th order (when I say complicated I'm sure I'm not talking about the same complicated as you guys think of
Okay so if I up my budget a bit are there any recomendations for a tweater/woofer combo that will require a more simple crossover to complete? I have no problems with any of the other construction process as I've done it many times in car audio, just the crossover thing still has my head spinning and I'd like to start off in baby steps. The plans from adire sure do look good, if I can get a vote of confidence from someone on my ability to complete the project sucessfully I just might take it on
Otherwise throw some more 2 way options out that can utilize a much more simple crossover please.
Oh and btw, I do have some adire extremis on preorder, am I just being to impatient and should I wait for those to build? I'd like a practice round first though and could always use the extra speakers and something to do
You guys have been most helpful so far, much appreciated.

what about something simple?
I'm just about to order the wideband CSS 4.5 drivers. They go up to around 15 kHz and don't need a crossover. They should also go low enough in the bass, depending on tastes and box configuration. You could always match them with a sub later if the bass is insufficient.
I've been in communication with Bob, who I guess is the owner of CSS, and he suggests that many people who have listened to both prefer these over the Jordan JX92S, at least in ported applications. Bass with the CSS driver is better do in part to Adire Audio's patent pending XBL driver technology. I took a look at the patent application, too, before ordering. It's pretty interesting.
The cost is right up your alley and no crossover makes it hard to mess up I've done some modeling of this driver and it looks like in the smallest parts express box, in a sealed configuration, it will be down 3db at roughly 77 Hz.
