I also have a pair of OHM L bookshelf speakers that I have owned for over 30 years. I custom upgraded these myself a couple years back with some very good Morel woofers and the OHM sub bass activator circuit (similar in goals to Merlin BAM). These are not teh smoothest of my smaller box speakers, but for pop/rock music, they may just be the most rewarding. Of course, I am not a speaker designer and would not claim my custom enhancements to be teh best. OHM sometimes offers these completely refurbished with new drivers and circuits for $599. They sold for $499 and were my favorite smaller bookshelf speaker back then in 1978, so you can get an idea of teh potential value factoring in inflation, etc. with these nowadays. I'd like to hear a pair of OHMs professionally upgraded Ls. or even larger C2s or Hs.
