You said it sounded like 18" Subwoofers strapped to your head. God bless you!
The Pro 900 will not respond to my super slope so they can slam you and deliver low to mid transition very well.
Enormous amounts of Bass are gonna interrupt the delivery of the early mids. Even if the driver is able to articulate them you will not be able to discern them. Your head is shaking and the cups are farting air down your neck...it's not the best way to listen to mids..and anything else.
I said you need 80% Hip Hop library
and a desire to push your eardrums to the limit with the amp.
You were warned. gelocks ..his review shoulda been a warning and mine shoulda too. They are bass cannons. I'm finally getting around to listening to Earth Wind and Fire with a raised mid eq. They play just fine.
So yeah...for impact and mids the Pro 900 will put you there and not allow you to cross insanity bridge. I liked em a lot the 2nd time around but I like my cup farts on my neck where the jaw line and ear meet. I'm an extremeophile.
Did you watch the vid...
Your bass papers....
The SZ2000 were worth a try. I didn't lose too much $$$ and now someone else can enjoy them. I guess in this hobby it's sometimes worth the risk of trying to find that one sound signature that makes you say, "that's it, that's the sound I've been searching for my whole life".
