Elso, I failed to calculate the very precise size of enclosure necessary to make all the system work properly. Generally speaking, if you have a very very small listening room and very up-close position, and if you still do not play very loud then it might be wonderful near field monitor.

That's exactly what I'm doing. I have a small room, walls close to the speakers, big sofa, etc etc.  Recently I moved my seat even closer than it was so now the head is about 2m from the tweeters. To my surprise it did not spoil the coherence. I also attempted that Sumiko speaker placement method. Was quite caricatural in my case as I cannot move the speakers much due to the constraints and the changes were rather small but I did reach some interesting point where the sound was definitely louder and cleaner. Playing Bruckner 8 by Wand (Harmonia Mundi LP), I could touch that madness that struck me when I first heard that LP through my Stax chain. I did not experiment with the volume either, sticking to your initial recipe. I only added 10cm mineral wool at the back wall and 20cm at the bottom (almost covering behind the ScanSpeak) to decrease the MF output through the PR. I did not detect anything re the base extension and measurements were rather unreliable, but the MF output was gone. The main motivation to look for the base extension is my hope to add some "LF breathing" and add spaciousness to the sound. 2nd motivation is add more of that "motor", the driving force of an orchestra. The idea sis to add a woofer with the same Scanspeak PR to match one to the other. Stacking PR woofers seems doable, REL shows it with one of its series for whatever it's worth. Another idea to open up the sound is to add a supertweeter. There are Fostex with big alnico magnets.

Paul, my turnover times are only a bit shorter than changes in the catholic church, so I'm looking for a modelling tool first. Looks like I've found something- WinISD. Fortunately PR's are quite popular now, so there is some information on the web. I don't think I'm buying the one-note description of the PR.
