How Much Do Your Subwoofer(s) Cost Relative to Speakers

I am using my old REL r305 in my second system.  It was in my main system for 16 years.   That is a 2:1 ratio given the subs original $1600 price.   

My main system has a pair of Forte IV.    I needed a sub last year but my daughter was getting married so I needed to keep the budget tight.  

I don't always use a sub in that room.   Mostly for movies.     I ended up buying an Earthquake MiniMe dsp12 for $675 delivered.   It turned out to be a really good sub for the money.  Has DSP room EQ.    So that's about 8:1.   

In a perfect world I would have a REL Carbon or something like that in there but maybe someday.  

Dynaudio Confidence C2 Platinum: $16k
REL S/510 six-pack: $18K

Not counting cables, and ignoring what I actually paid for them.

How would I list a price for Do it Yourself Subwoofers? To me they are priceless. I use the best subwoofer drivers available at the time, build an enclosure with the most solid material and bracing possible, and finish them in solid Oak hardwood boards.

I have three rooms but my 2-channel room speakers and stands list for $25,000 and I use a 3rd identical $12,500 speaker for a center channel for when my stereo preamp is in Home Theater Bypass mode.
