Match for Von Swcheikert VR 4 top sections


Maybe an odd question but I was able to find some VR 4 top sections that have lost their bass units somewhere in their life's journey. Should I try a set of good quality subs or go DYI  to try to pair up. I hate to see these high quality speakers go to waste. Any suggestions would be appreciated.

I believe the crossovers in these go down to about 150hz or 125hz.

Thanks Ozzy,

I will have to think this through a bit. Maybe experiment a bit. I can always part them out for what I paid for them.
I had a pair of these back in the mid 90s. I remember one time disconnecting the woofer module to see what was what. There was absolutely no midbass to speak of. I'm not sure that midrange plays down to 125 hz.
