I'm with Horst on this -206 'unlistenable without a filter'? What have you been doing to them?

They're not exactly a soporific listen, with that rising response, but they're still one of the best FR units around at the price. A pair of phase plugs improves things of course, and I'm sure EnABLing them will reap rewards too, but stock, they're a good unit. My friend Ed runs an unmodified pair in his Vofo folded TQWTs and they're very effective, even to someone like me, who hates a bright sound. Sure, a filter will flatten things out, but its not an automatic requirement.

Hi,

Sorry for harsh words. I was mostly thinking about ways to cure the rising response, plus something more like a Line level baffle step correction, when these speakers are not used in a horn, but other types of enclosure, ML TL for example. I bet they don't need a BSC when used in a horn, and the phase plug could take care of the top end.

Regards,

Vix

Oh yes, it's useful in an MLTL (TQWT's extra gain is usually sufficient by itself), no argument at all there. Best simply done as part of the BSC circuit -usually it doesn't need much else. The plugs sort out the mids & top nicely too.

Yup regarding Sonido!
Have tested SFR178 on OB and sound is really good. Lacking of bass of course but Q is really low, so no surprise. However a really even response with no shout.

BIB on the way for these so we'll see....

Cheers!
