I will try to save you the headache of buyers remorse.
I have been thru about everything mentioned here,
and I would say hands down, Hawthorne Audio Silver Iris.
I have been using OB about 5 years,many different
size baffles and many drivers,for me nothing came close
to Silver Iris. by the way stick with U baffle at bottom
and flat baffle on top about 50% U and 50% flat at top.
I use 1 Eminence Alpha 15a per side.

I seriously doubt this.
Maybe *many* of the drivers mentioned here, but even then we would need a listing.
The silver Iris isn't a "full-range" driver, it's a co-axial 2-way (..which has it's own set of advantages and disadvantages.)

Besides, the most important thing is to listen to the different drivers and enjoy them for what they are. Just different flavors for us to savor.
I have to agree with Dave. I don't dislike the Silver Iris, but it certainly wouldn't be on my short list of drivers.

According to MJK, the crossover point should be low to avoid the quarter wave resonance, and I think it's sound reasonable. So a 4.7mH and a big capacitor (can't remember value at the moment) will feature the alpha15-crossover. Not really sure where the f3 will be since of the uprising respons of the driver.
I will go for driver with atleast 6" or bigger. small drivers sounds small, thats why I only wrote 8" drivers in first post
Jordan, Audio Nirvana and supravox, are these available in EU?
The fullrange needs to be 92-93dB/W/m to be a proper match to Alpha15, a few dB/W/m more are optimal. the TB-1808 has 92dB/W as mentioned, could the just enough? The FE206EN has best sensitivity, great candidate.
Where is it possible to get the phase plug for B200? or is it standard for the driver, doesn't see any plug on the picures...

Jordan is a Swedish company (drivers made in Asia), SupraVox is French (made in France AFAIK), Audio Nirvana is a US house brand of Common Sense Audio (made in China), a distrib in Denmark (ALTOHT.DK - ALTO)

email me.

Thanks for the reply!
SO, now I got even more drivers to choose between
I'll send u an email if I choose to order the B200, not sure yet. And I probably want order any this year, I may soon move up to Luleå (to study) so I'll wait until I know how it turns out.
Here's my current project using the Tangband w8-1808 and Alphas in H-frames.

Hi
As I am using Visaton B200 with Eminence Betas on OB, well..Visaton is a love-hate affair. It can do some things very well and it is suited for OB, but on the other hand it suffers from uneven response that can get on your nerves. Phase plugs make it easier up to an extent, but you may easily find that you need/want more equalization to cure this. Passively, it is usually done with an inductor/resistor combination so it shelves frequencies above a certain point, but then you may find out that you don't quite like the effect, as it can sound grainy...so you start tweaking..and turning in circles...
So, my recommendation is to find a driver that can sound smooth without needing a lot of EQ/correction. Alpair 12, despite having lower efficiency, seems to be like that. On the other hand, you can try to find second-hand car speakers (blaupunkt comes to mind) and experiment with the upper baffle which can be just a stiff cardboard, until you hear what your preferences are...

Have you considered the Fostex FE-166En or the FE-168E Sigma? If you want to use a passive crossover then I believe either of these drivers would work well. I would be concerned that an 8" driver might be too efficient.
If you want to cross the full range driver in the 250 to 300 Hz range I recommend that you size the baffle to be consistent with that goal. I do not believe a "nude" driver is going to mate well with the bass system at the frequencies you specify. This type of system is dead easy to simulate and design, you can avoid many potential mistakes by doing the engineering first.

What I meant was that if I order the B200, not from you, I might be interested in order a pair phase plugs from you. Not the drivers.
Thanks for the link! Looks really great!
yeah, the less crossover components needed the better.
I'll not go nude, all comments here have changed my mind (even thou it would be rather cool). I looked at them, but its hard to "see" how they sound like from datasheets. The FE166 was actually one of my first choice when I started looking around what FR drivers that was available, not sure why I dismissed it...
Just for the record,
I have tried about everything you guys have mentioned.
over the last ten years,Open baffle,frugal horns,Saburos,
Buschorns MK1 & Mk2 voight pipes, BIB,
Anyway for me I always come back to Silver Iris on Open Baffle,
I owned and operated a professional
recording studio for 15 years, I know good sound when I here it.

What is it with Silver Iris you find better than the other? Midrange, dynamics or something else?
The thing about Silver Iris,they have such an
easy and full presentation,extremly dynamic,
very smooth from top to bottom after about 60 hrs of breakin,
I have tried a bunch of full range drivers
out there many Fostex , Hemp acoustic,Audio nirvana,
a few of the Mark Audio, B200,
My opinion none of these even come to silver iris
in smoothness across the spectrum, Silver Iris
have great mids,buy a pair and judge for yourself.
on Open baffle the other speakers mentioned here
sound toy like in comparrison.
you are going down the same road I did,
I am just trying to save you some time and money.
I wish I would have discovered the Silver Iris before
I went thru all the drivers and enclosures I did.
to sum it up. I am very content with Silver iris
and I am finally finished chasing my tail,and spending money.
and that makes my wife very happy indeed.
