    Boondock-I thought you were over at DIYMA? Really, take the time to read up on the reviews by npdang and shinjohn. There reviews are amazingly helpful and they have experimented with so many drivers. When you search, do an advanced search and makes ure you put their username in an select "threads started by".

    Scott already gave you the big 6.5-7" midbass comparison. and shinjohn has a massive tweeter review.

    If you want a combo that "just works" very well together, it would be hard to beat the Seas CA18RNX tied together with the seas neo 27TAFNCG tweets at that price. The combo is just over $200.

    I had those L18's and they are a great choice too, I just think the CA18 is more fool proof and easier to tune and work with.

    Two other midbass drivers you might want to consider, one of them is in that review scott posted. Here are two drivers I have been looking at. The 6.5" Aurum cantus would be a good choice too. All three drivers are on sale right now. My preference would lean more towards the Usher. Npdang reviewed it and Zaph reviewed it-both seemed to like it. See my link:

    As far as amp power, try to go with something that will give you at least or approx 50W @ 8ohms (so a rating of 80-150W @ 4 ohms works or close to it). Your tweeters won't really need as much power as your midbass since they are more efficient and typically can handle less power thermally.

    Alright guys Im looking through these and it seems some of my best choices would be the: W18NX, Vifa XG-18, Glass or Alluminum RNX, but this is just preliminary. I still wanna look more into it which I am, but first wheres a good place to see the prices for all these... the only place I can seem to find that carries Seas is Madisound... if yall got a good place to look at prices that would be great.

    Then as far as the amp goes... are all amps capable of 8 ohms even if they dont list it? (sorry for the nubness)

    And durwood I am on DIY but just seems to be a slow response on there... thanks again guys this is the most response I have got on any of the 4 or 5 forums I posted this on.

    Amplifiers can handle higher loads no problem, it's actually easier on them then lower loads (ohms). And don;t worry too much about less power going to a higher ohm load, the efficiency of 8 ohm drivers is actually makes them equivalent to 4 ohm speakers essentially.

    More Tweeter reviews

    Places to buy raw drivers, there are a few more places out there, but this is where you will find the bulk of them.

    www.solen.ca (canada)
    http://www.zalytron.com/
    www.timbre-audio.com
    www.partsexpress.com
    http://www.acoustic-visions.com/

    Responses are not normally slow on DIYMA, it's just that 2-way setups have been discussed quite a lot, so people don't respond to those types of threads as much. It's more of a point in the right direction because it's more fun when you can learn it yourself. Otherwise all you will get is differing opinions anyway.

    here are some more good threads to read. Some are very indepth and will take some time to digest if this is all new to you. Just be patient. If you are willing to learn it can be fun and could save you money...or not if you like to experiment.

    great links by durwood

    if you're going to get the f/g rnx solen.ca may be your only choice unless you get it used. if you decide that route (which i suggest since they are supposed to be pretty easy to blend with) get the drivers asap because they dont make them anymore.

    they are about 150/pr shipped IIRC. the vifa's are around the same price but the w18nx are a lot more

    Yes the Seas Reed version of the RNX series looks good. They did some things to lower distortion in that driver compared to the other versions of the RNX series.

    Just so you know, the aluminum version is very hard to use in a 2-way setup because of the cone causes some weird things to happen in the response curves up in the higher frequencies. It's better used in a 3-way IMO unless you are ready to do some serious tuning and the tweeter has to be able to play lower down in the 2-2.5Khz region.

    maybe another option: HDS 810921 + 830883.... smooth curve, laid back sound, but able to produce a firm kick in the right enclosure. The tweeter is pretty smooth aswell, no sharp ends or boosts in the high-range (didn't you review this tweeter one, durwood?)
    Xenia & Isabelle, totally in love!

    CLARION HX-D2
    CLARION APA4300HX => Fountek NeoCd1.0 + TB W4-1337SD
    CLARION APA4300HX => CSS Trio8
    CLARION APA2100 => Dayton IB385-8

    That is a great tweeter (but I didn't review it), and I plan on using it in my fiances car (if she lets me), but since it is a large format tweeter it won't fit in my car. It's a great value tweeter with excelent characteristics. It competes with tweeters that are 3-4 times it's price. The mid would be a good one too, actually almost any mid would work well with that tweeter, it's very versatile.

    Alright guys sorry it took so long to get back my internet had been acting up and got caught up in work and stuff... Well Im thinking either the fiberglass or tweed RNX 7" mids are going to be my best choice. My question is if I do decide to go 3 way later, would these be a good choice? Or is it even necessary? Im going to take another look at the reviews for mids again, especially the ushers and the ACs, but as far as price and quality go these seem like the top choice so far.

    Tweets I really haven't got a chance to REALLY look into but I figure I need to match the tweets to the mids so I should do that after I choose my mids. The Seas 27TAFG/C is probablly a good choice for these.

    Then amps... still looking at them at the moment and I will post up more links as the night progresses but do you think any of these are decent?
    Lanzar Amp 1
    US Amps 1

    Still looking but are there any suggestions yall could make? On particular amps to get or to avoid or even brands to get or avoid?

    Then I still kinda need an idea of what wires I should purchase... I can't seem to find the list that I found previously but Im still looking.

    Once again sorry for the long pause in this, but as always all help is appreciated.
