Diy Watt/puppy clones: follow up

They are 'developing' in very good direction. And in my room/amplification situation, which is far from ideal, i can already separate speaker characteristics. Soundstage is wide and deep. They are 'sweet' and detailed in same time. I cannot pin-point any faults from top, midrange, lower midrange....and ! Well, last octave of audible bass (Measured 31Hz) is not very good. Still 'boomy, probably room and somewhat design are to blame. As you can see lively room stores a lot of energy, and with the woofer just inches from the floor it's probably bad combination. Any suggestions and advices are welcome!
