Looking for guidance on what to do with this

Hi all,
I have acquired (inherited) some vintage Mc gear and JBL speakers all enclosed in Barzilay furniture.  I have 4 speakers each one measuring about 24" cubed.  The drivers are JBL Model 075 (1979-82ish) and JBL D131.  The main cabinet is a flip top that holds turntable, mc components and vinyl.  My dilemma is that it is taking up too much space in my climate controlled garage.  I LOVE the way the speakers sound and those tweeters are sweet to listen too.  So my loaded question is:
1.  Does the furniture have any value? Should I keep components and speakers and scrap the large cabinet?
2.  Should I keep the drivers and DIY some smaller, more modern enclosures?
3. Should it all be kept as a furniture set and sold as is, and in memory purchase something like (2) JBL L100 Classic 75's 
Would like to know what I really have on my hands and what its sell-ability is or what the worth is.  

Thanks in advance!
