JBL 4349’s used! See here

The amp is 80 watts or 40 watts triode

@traudio , my amp is the Cary V-12 (which I know is not the same as your integrated) but for the sake of comparisons it is switchable between 50 wpc triode and 100 wpc ultralinear (so it’s not way crazy different than yours in that respect). This is something you can easily play with and decide for yourself, but what I have found is that I much prefer the sound of my amp in the 50 wpc triode mode.

With that typed, I don’t have any problems at all using triode mode to drive an old pair of B&W 805s (by old, I mean from way back in the B&W Matrix series) with a sensitivity rating of 87. It is worth noting that a few years ago I moved my system from the living room to a smaller bedroom that is now my listening room and I listen quite near-field, but even when it was in my living room I listened mostly in triode and was happy with that. When I did feel the need to really rock the house down I simply flipped the switches over to ultralinear and it could make those speakers scream.

So I am not trying to sell you on B&Ws, but what I am getting at is that I don’t think that you have to restrict yourself to considering only real efficient speakers.

I, and everyone (not me and ..) The old fat woman with a moustache who taught me grammar would be looking for her slapping ruler.

I know you have subs, BUT, they need to take the low bass out of the line level, then back to amp, some do, some don't.

Some give the speaker's a break, but not the amp. Some give the amp a break which gives the speakers a break.

With borderline power for 'not too efficient' speakers, you want to give the amp a break, so it has plenty of power when not trying to create low bass.

Subs self powered?

front firing?

Fit next to where mains will go?

That will give you Stereo Bass, a wonderful thing, at any volume.

btw, did you see the level controls on those Infinity Kappa 9’s?

I am a big big fan of level controls, so a speaker, which had no idea of it’s intended space, can be adjusted to do a great job ’in that space’. move them, adjust for that space.

I use an inexpensive SPL meter from Amazon, on my tripod, and 29 single 1/3 octave test tones.

final, use your ears.

amazing bytes

$25. delivered is a historic low price, often low is $75. One came up for $9.99. I jumped on it! Gave it to a friend

a/an historic .... who knows which is correct?
