Default Suggest me a Wideband for OB

To run without crossover, with bass aid from an Eminence Alpha 15 or 2x Peerless SLS-315, or similar woofer(s) for about 30-150hz.

Requirements:
-High efficiency (95dB and up)
-Very linear (also in the HF)
-Low price (pair or quartet must not go over 400, exceptions possible but not by much)
-Available in Europe (please consider european price)

Possible to run two in series if cheap enough, to raise SPL.

Eminence Legend 875 from Spectrumaudio/Breitbandlautsprecher might be worth looking at, if its available at all
Seems to roll off smoothly around 8khz
Cone screams fore coating

Maybe I wasnt clear: I dont want a rolloff before 18k or such. I wont use a tweeter.

So far, it seems that only some Fostex (FE166E and bigger siblings) meet cost requirements, breaking that, there are a few Lowther and Supravox which could do the job, but it's a pity to cut their low end (I do need 30hz).

Default Possible candidates

Possible candidates are:

-Fostex FE166E (single driver per speaker), rolles off at around 18k, 95dB

-Jordan JXR6 HD (2x in series), the most linear response I have ever seen. It should go past 20khz. And in OB should rolloff nicely on the bottom octaves. It may be a little expensive (needing to raise sensitivity)

Maybe the Ciare HX201 with compensation like it is usually done with the Visaton B200.

If you are going to consider those, you should also add Mark Audio Alpair 5 or 6 to your short list.

Added.

The quality of the midrange is for me of paramount importance.
If the plan of using a single widerange (for mid andhighs) wont work, I'll have to go 3-way. In that case I have seen a Goodwins 12" that works marvelous up to 10k or more.

It seems that a wideband with nice response is always very unsensitive, there must be a correlation of sort

Checked. 96dB sens, 5-9 Ohm impedance are acceptable, paper cone (good, its my fav), from 9k up needs EQ. I can do it digitally but i'm trying to avoid at first. Price is also good due to Ciare being an italian company.
Overall is a discrete driver.

Someone has a link to an OB project that used it?

For compensation you mean bass compensation or EQ?

I answer myself about the Fostex.

The 166E seems to whizz, the 167S should be a better choice. I saw it paired with just one Eminence Beta 15. I'm trying to get more information about those speakers.

Default added AN

Added:

-Audio Nirvana Super 8 AlNiCo (which would stretch my budget of a good 100 bucks)
-Audio Nirvan Super 12 Cast frame
-Audio Nirvan Super 10 Cast frame

in this order of preference.
