I've built these in the miniOnken box. They are very good sounding. I like them very much, but I would not use them without a subwoofer. With my Tempest they sound wonderful in my setup.
In my experience I find most speakers can do with a good subwoofer. There is bass and then there is........ bass.

that's sounds really good, what's the sensitivity of those speakers?
80dB.

Is this because it's a dipole or how does these thing work?

That is the sensitivity of the driver I think. But the implementation does change the efficiency a little...methinks.

It depends how you measure it. Hobby Hifi says 80dB, Klang und Ton says look at the frequency graphs (where you can see most of the time it is indeed close to 80dB except for between 100 and 300 Hertz where it goes to about max 85dB)

Despite this, do they still go loud with just 8W of power? I keep imagining speakers with sensitivies that low needing the volume turned all the way up!

Actually my version of the Ladyday is closer to closer to 6 watts then 8 watts.

Yes it goes that loud ..but it's a small little room. However according to Dave Dlugos it does indeed not respond well to little SE amps. On the other hand though I was suprised that a 50watt gainclone did not go all that much louder than my 4 watt SE amp.

I too am listening to the CSS FR125S in open baffles. First for a few weeks with a 20 watt/ch, then a 40 watt/ch gainclone and Channel Islands VMB-1 chip amp, then a Sonic Impact 8 watt/ch, then a Wright Sound 3.5 2a3 SET. Between the 40 watt chip amp and the 2a3 (3.5 watt/ch) SET, the potential gain was about the same (except the sonic impact was weakest). I just do not have any bigger amps around. These days I most like the Wright Sound with the FR125S open baffled.

This setup also in a small room.

Hi,

I think that most of us don't really push speakers past 80db for normal listening anyway. I don't like music too loud and probably don't use more than a watt or so of power.

Thanks
raja
