Here's an interesting experiment [message #18829]

I hooked up the Altec/Great Plains 902's in place of the JBL 2446's.
And slightly (hah!) different horns.

Same 1200Hz crossover. Same, 111 dB efficiency.

The Stenway Grand I was listening to became a tinkly upright and the voice went from warm and rich to nasal. Okay, that's an overstatement but the 2" format and great big horn creates an utterly different sound.

Money can't buy happiness but it sure does control good sound!

My wife would shoot that if she saw it in the living room.

BTW - you didn`t tell us how you (finally?) solved your capacitors vs crossover puzzle? Specifically, did you try those Mundorf Supreme?
Review?

Nothing was solved but the GIANT speakers put me off the puzzle!

I tried the Mundorf Supreme .33 uF in the attenuation and there was very little difference between them and the Kimbers.

I am about to try 10uF Obbligato oil caps from DIYHIFISUPPLY in an amplifier circuit. When funds allow I will order more plus 20uF to try back in the crossover. They're quite reasonably priced.

Hi Bill - I'm confused about your experiment... [message #18834 is a reply to message #18829]

Unless I broke another tooth off in the 'ol gear train, the 2446 is 2" with no real throat development and the 902 is 1" with the old RCA throat development?

Is that a fair comparison?

Why don't I believe you would get away with that?

About a month ago my wife was looking for a new truck for work. She wanted a Dodge Ram but was unsure due to its size. At the dealer she was standing next to a Ram Big Horn 4x4 w/extended cab, and I made the comment that her butt looked much smaller. She bought the truck, and, yes, it does have Hemi.....
