Hope everyone is stay safe and healthy.

I currently is running a JBL 4350AWX and the HF is clean, detail and just beautiful , however the LF seems to be lacking clarity and that round glorious bass,
I am currently running a boulder 2060 Class A 600w on it... but I honestly can't say that I am not " FEELING " it ,,, so just want to check in with you guys if
there was experience from the community.

I am planning to use a CROWN XLS 2502 , or a QSC RMX series to see if the higher power will create a better control over the dual 15" woofers on each speaker.
or something like the Crown https://www.crownaudio.com/en/products/i-tech-5000hd

Thank you for any advice !
