I'd like to see more like this, with measurements. Anyone else?

Just stumbled across this: Funktion-One | Products | Resolution 1.5

..Uses an 18" woofer in a compact vented enclosure, with a 5" cone in a front horn, instead of a compression driver.

Don't know about anyone else, but I find a 5" cone driver being loaded in a front horn for 500Hz-15KHz at 112dB/watt with 90 degree horizontal dispersion very intriguing..

Also check out the German hifi brand Avant Garde, they also use a 5" widerange driver in their big spherical front horns. If such big horns were cheap to buy, I would be experimenting. The excellent Avant Garde Uno which I heard half a year ago had only one disadvantage (next to WAF) which stopped me from buying it: the price...

Mmmh the idea of a bib-loaded 5" with a big front horn as well is strangely appealing to this geek...

Just came up with a inverted baffelstep compensation circuit which makes the eq'ing obsolete, the result is actually really pleasing an they now reside as my main speakers together with the THAM10 crossed over at 240Hz.

the RC circuit consits of a 8,2uF cpacitor paralelled with a 10 Ohm resistor connected in series on the plus lead, so nothing complicated, initially i tried a 6,8uF but it made the sound to dull and lifeless.

Another thought, I know there's been some time passing since my last contribution to this thread, but how about using one of them new shiny 2" drivers from faital instead, the HF204 och 206 for instance ?

The reson for this thought is that even if the result at present is rather nice, especially with the RC-circuit in place, using a propper 2" driver (as sugested above) wich reaches 500Hz, and using a simillar RC circuit to compensat for eventual horn honkyness, would that not provide a nice and power solution for the 500-18k range ?

Brilliant use of supplys Martinsson, I've thought about a setup like that more than once. Glad to hear that it actually works. I've been having thoughts about a 2" compression driver on a large flat baffle too, Kind of like a flattened out horn.

Hello, not bad that you are still listening to the same setup for over a year and a half(!). As far as your suggestion goes, I don't know if it is worth it though, as you still get a full octave lower with the TB, which gets you very close to that "full range" magic. Otherwise it will just be another horn two-way. And those compression drivers sound a bit strained going below 600Hz or so.

The next logical step would be to get a bigger horn and maybe use a 3" and see if you can cross even lower to cover more of the "full range" driver pass band.
