Is bi amping worth it ?

If I am not mistaken it seems that at the very least , that bi amping my khorns , using one mono block for both low frequency , woofers in both speakers and the other mono block for the midrange and tweeters in both speakers . That should give me the ability on certain music to increase power to the low frequency amp if I desire to ?  I believe this is correct and may be all I need.   Will find out this weekend hopefully.    I am not looking for a big change I am quite happy with the system and I love the sensitivity of the horns  , always have but just feel like could use a touch more low end from time to time.

yes these speakers are set up for easy bi amping . 
 

better quality power. ?  I know there is better of course but I would have thought the McIntosh 601 monoblocks and McIntosh tube pre amp would be of sufficient quality power

that looks like the perfect crossover  . Inexpensive enough to give it a try.

I did reach out to Greg last year when I had vintage khorns .  Were going to upgrade all Component’s with volti and then I can across an opportunity to trade my vintage horns in on a new pair of horns and did that.  The new enclosed horns were much improved over the vintage , especially the bass.   Not looking to upgrade these speakers ( as yet )   
 

I see where if you buy direct from REL they give you a 60 day trial.    I may try a set of the classic 99 . I admit I like the way they look cosmetically ( already have a large  black box subwoofer for theater)  just hoping they will add enough.   Seems two of them should. ? One to each mono block 

Well , from all the comments so far certainly makes sense to try bi amping.  Doesn’t cost anything to try passive bi amping other than another set of speaker cables. Will try that first and see if any difference .  I have the mono blocks and the pre amp supports two main outs.    Have ordered some additional speaker cables and will try this first and report any difference with this first move , probably this weekend. 
 

thanks again for all comments and advice . Greatly appreciated.
