Guys.... you have lost your way!!
As keyboard players don't you remember the days you used a keyboard amp?
Remember that full sound?
Remember the bottom and punch?
Remember it sounded like it came from the keyboard you were playing?
And not some mystery location in the air..
PA systems are "public announce" systems.... designed for voice and general background sound.. Today's standards... make it louder.... not better..
The newer gimmick concepts are designed for a solo instrument like guitar and a vocal..
Years ago we were peaked at sound on stage..
The bass player had his bass amp (near him and you could locate the bass player by the stage sound..)
The guitar player had his perfect sound with his own guitar amp...and yes we knew were he was on stage..
The keyboard player had all the detail sound he / she needed with a keyboard amp...an amp designed for full range sound.. usually two way, many 3 way systems.. and the sound was right there at the keyboard.. It felt like you were playing the instrument you were hearing... No need for the monitors usually needed with the current sound systems if you want to hear what you are doing.(maybe with the auto/ push a button stuff today ..you don't care..)
I still have the same Keyboard amps for the last 32 years.. As a keyboard player there is nothing better.. Especially on stage..
Buying lighter stuff... good for your energy use, but do you really think it sounds better?
There are reasons why the old gear was built in cabinets with design features, and extra components as in 3 way.. tweeter , horn, and woofer.. with crossover points... and 15" speakers (yes there is a difference).
I have never been happy with my keyboards coming from PA speakers up on polls... it leaves me unattached with the sound and keyboard..
Just rethink where we are going.. and for guys that still have keyboard amps (Bill you still have your Crates?)... listen to them again and compare to the new gimmick stuff...
