22 wpc mono-blocks enough power ?

This is the doctor writing. Sure you can get 100db out of your La Scalas from a watt but as Joe (Trelja)- my very good buddy, also a conissuer(sp? they don't teach that one in Med school) lover of fine fast cars and..... well no he is a devoted husband.... put it- from where? Its almost all squawker which carries the bulk of the sound by design. The crossover frequencies in the AA type are set that way. So you can make your ears bleed before you hear any real musical bass with low wattage. I find a muscular solid state amp works best. That being said, I generally only need about 50 watts from an old Mac amp, but I am looking to buy the 105 version, it rocks my jelly roll soul. If you think that's nuts I play them in paralell with vintage JBLs C36s (with the 030 drivers) with about 100db sensitivity. That being said I have heard my very pair driven by EL84s with very pretty sound but at relatively low levels and auditioned them with 2A3 bottleheads playing Grover Washington's Mr. Magic at reasonably loud levels, the guy admitted to blowing a tweeter diaphragm at one point, because "it wasn't clean power". When I want my cochlea to take it easy I use other equipment. I couldn't be more emphatic, the 15 inch woofers in these speakers simply will not move correctly without the power and I will add you can and will cause almost any low watt tube amp to clip, even in the midrange, if you listen to loud music. Joe and I like it at 90-100 db, sorry if its not audiophile but we also insist that its clean and all there. As a side note Joe doesn't really like the La Scalas, power or not and makes me play my JMs when I hang out with him.

I want to get real "technical" here and tell you all that the La Scala is rated at a nominal impedance of 8 ohms not 4 . I don't know why Sean started with that assumption. Thus whatever data was measured at 8 ohms is as accurate and reliable as its source and no assumptions, formulae,or other manipulation of the numbers need apply. The second part is that they are loud as you would ever want a speaker to be. 22 watts sure, go ahead, especially from an 845/211 SET. 222 watts even better but its not the volume its all in the reactance over the resistance which is = Q, I gather from their behavior they are low Q speakers, but I will have to look that up. Or I can ask Trelja or Joe as I know him what he thinks.

Sean: I am just quoted the manufacturer claim for the K-33 and if you check out the website for Klipsch under current production of the Heritage series they still claim a nominal 8 ohms even if they changed the woofer. BTW all La Scalas are "vented" not ported, inside the back of bass chamber the cabinet , I have seen some with the point of the bass cabinet open if that's what you mean. I have no doubt that they pull more current than the tweeters or sqwaukers, that is probably the reason they sound much richer with more headroom.
