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.

Best Regards,

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)

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 Luleĺ (to study) so I'll wait until I know how it turns out.

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...
