The 12P are (at Strassacker, Germany) 229€... I'm just not sure if it's per pair or per piece. At chr70 it specifically says it's price per pair, but here nothing, so it shold e per piece. Also, Slovenian distributor told me that 10P are 150€/piece...

By UK dealer you mean Oak Audio?
 
Fullrange TB for 2015

Good link, thanks.:)

They are very reliable and have fast shipping. I have bought my drivers from them.
Before buying I suggest you to compare characteristics of FR's with different diameters.
Smaller FRs than 5 inc have not enough bass range.
Beyond 5 inc FRs have high frequency enhancement. It would be 6-8 dB over 10kHz and bigger enclosure needed.
In my opinion the best choice is around 5 inc.
And it depends on your wallet as well. :)

I like these w5-1611saf, almost dirt cheap, biger than my chr70's and stats look good, too. Might try them. Plus, these Bulgarians are cheaper than any store I ever saw. Again, thanks for the link. :)

This W5-2143 driver is better than the W5-1611. I have already heard both of them. The price difference is not significant.
Come and listen to it. You are not too far from me. ;)

What causes the spike above 200 hz then sudden drop down towards 70 db on the 2143 in karlsonator simulations plot posted ? In Latest design for 2143 post #1573

Thanks...
I just did two sims of the W5-2143 in a MLTL and a Karlsonator, and a MLTL for the W4-2142.

2143 looks like an impressive performer in K'nator with 91dB bass (after baffle step losses) and f3 of 60Hz.
 
It's still quite new, so presumably hasn't established itself yet. I'm a little surprised at that; while the 5in category isn't the most popular, there are a few units that do well (Jordan, MA etc.) so the market exists. The impression I get with TB is that as far as FR driver sales go, the majority tends to be in the 3in & 4in category (with some 8in). The 5in, 6in models don't seem to appear as much in terms of projects etc.

Agree. Most people use FR as PC speaker or add a FAST, "helper", sub, whatever. IMHO.
 
I'm not having the good results I was expecting...My w5-2143 are in ported (2" or 50.8mm) boxes 14L with 9" (228 mm) width baffle. I am going to experiment further with dampening/stuffing inside and then baffle step compensation (paralleled inductor/resistor in series). I was hoping for a better point source image and wide soundstage...However, maybe I have too high expectations comparing to my other two-way ScanSpeak sets I've build. To their credit, I have beginning to appreciate the details the 2143 is capable of for movie dialogue -- makes a great center channel. The bass is a little weak and there is a slight (and I emphasize slight) excessive mid high frequencies that could be tamed for better coherence...The bass frequencies is what contributes to a good soundstage, and without it, they sound uninvolving. I'll update when I have more time to experiment..

cheers!

Sound absorber

To improve sound quality is important to deal with room acoustic. I made experiments with a sound absorber sponge. Results are astonishing. Deeper stereo space, bigger and deeper subsounds and the higher range is smooth and realistic. This application is decrease the effect of room acoustic.
I go on testing and make a pretty coating on it. :)
