604s are 515 +802
Most are crossed at 1500

It is with an IB arrangement, and that means the mentioned fr of 20 to 1000 HZ is going to be extremely flat. The 515 series are far quicker, superior, flat-er, and with way more high-end response than any 416x series. Its more industrial grade by design compared to the 416x. The 416x has a bit of (mechanically) equalized response to make it sound bass-y and sweet (?) compared to the 515 which is ruthlessly clinical, and that is the reason why many find the 515 to be lacking in bass.

Yes I know ! GM always,always, replies politely... He Da'Man ! It's just a matter of preference for me personally..I guess the point I was trying to make.. Is I feel the 515's are lacking in the bass department IMHO.. The 515's are more rugged.

FWIW- I'm going to disconnect the 802's in my 19's and measure my 416's to compare.. Could be apples and oranges though with IB and Bass reflex comparison.

Was strictly talking about woofers and not duplex's per say.
