2 x 10" woofers - enough low freq SPL?

Room gain brings that back up to near flat. Correct, the bass isn't prominent, it's just right.

Hi there...re wavelengths......
I take it your room isn't made of wood as mine is....then the LF response will basically goes through the wood/insulation and into the garden to disperse...then you will loose alot of your expected corner gain. LF travels through walls! OR are your room walls made of brick/ cement ?

I leave my front door open so any bass that gets out can come right back in again. This doesn't always work out though for I have ocassionally caught it stopping to smell the roses.

Actually, that's already factored in. 6dB increase x sidewall, floor, & ceiling yields 18dB, and we are using 8dB room gain. See http://www.woodartistry.com/linkwitzlab/thor-estim.htm

Just did the sums using the Dayton 10" MKIII, Sd = 340cm^2, Xmax = 18.7mm:
Using Unibox,
1 woofer linear (within Xmax) SPL :
20Hz 97dB
30Hz 104dB
40Hz 109dB
Stereo pair - add 5dB gain
20Hz 102dB
30Hz 109dB
40Hz 114dB
Now add say 8dB typical room gain:
20Hz 110dB
30Hz 117dB
40Hz 122dB

Wow!
