Did I? $39 ea?

I got them for my 802-8Gs. I thought I might like to try them with a large format horn...if I ever get one.

Ah, I see that now. I just did a 'completed listing' search. I didn't even look, I just bought them.

I'm going to bolt them right up to my MRII564s when I get them. It will be an interesting experiement to A/B the 802G with the 288s, all else equal. I might need hardware.

The 288s are amazing, but they are very hot. I have to keep the attenuation knob almost off on my A6s to tame them. It might work in an outdoor environment or a big auditorium where the extra HF might be needed to cut through the ambient noise, but that's not the case in my LR.

I should try increasing the crossover freq. too. Maybe running them at 800 or 1200 will take something off and give the 3156s a chance to catch up.

My adapters arrived today and I wasted no time trying them out with my 802-8Gs. I left the XO at 500Hz for the time being.

Needless to say, I had to turn the attenuator knob up from about 1 to 6, but they sound great. Not as in your face as the 288s and I'm thinking a bit more extended on the top end. I think I'll let my ears burn in for a while...

To be fair you should build fixed pad for the 288's to try to get the L-pad somewhere in the middle of it's range with the 288's.

To balance a passive system i like to start with the HF way low and bring it up slowly to more or less a point of balance. It sounds like the L-pad is hugging an extreme to get the 288's close to their balance point which is gonna make it pretty hard to make a fair assessment.
