Not yet, im putting up all the basic treatment first, and ill evaluate from there. Im also integrating dual 10" subs/ddrc-88a mimidsp. I'm hoping i can smooth out the LF response at LP with sub placement and then let dirac help with alignment and any other hiccups.
It would be good to run REW right now, to get an idea of where you are with the treatment, so you can still change it if it is not doing what needs to be done. It would have been great to have an initial "baseline" REW test with the empty room, so you could compare the results at each stage in the treatment process. Sometimes a treatment does not produce the effect you were expecting, or it does produce it, but then it does other things too that you were not expecting... If you don't have that "baseline", all is not lost! ... It's still not too late to stat testing as you build: that can often show up things that you were not expecting. Digital tuning can only help if the acoustic problems are already taken care of, fully. You cannot EQ anything that has a phase problem, for example.... - Stuart -
I must start checking the dates on these threads. Those photos show a very 'Pro' look. Well done. What speakers are you going for? Have you bought them and the subs and minidsp already? DD
Yes, i already bought everything. 2 x eve audio sc208, 2 x krk krk10s, 1 x ddrc-88a BM minidsp. I dont really want to install speakers till construction is done. Its a tight space and i dont want to damage anything. I could clean everything out, install speakers, test, and remove, but thats a HUGE pita. I'll roll the dice and trust physics and the advice/knowledge Ive received from all my smart friends. I think it'll be good.

Wow! V-E-R-Y cool! Love the "ultraviolet" look. - Stuart -
Thanks Stuart! I'm really happy with the asthetics. Now lets just hope i can tune her to sound as good as she looks. So far i'm about +/-8db except for a 20db cancellation at +/-700hz. Only ringig i have is around 20-35hz. Im pretty optimistic about the minidsp having a positive efdect. I'll play around with sub placement a bit and tgen post a before dirac mdat.
ok, here's about the best I can do with positioning the subs. It looks pretty good to me but I'd like to hear what you think. Do you think this is a good enough starting point to start using my minidsp with dirac, or are there any big red flags I need to address first? The big dip I had at +\-700hz was from that tiny little flat part where the computer keyboard/mouse go. I put an angled piece of wood over it for the test. I'll make a new top that looks nice to be permanent. The attached *.mdat is all speakers together. 2x Eve audio SC208 and 2x KRK10S There is a -6db low shelf on the mains for baffle step compensation No other crossovers have been set other than the ones on the subs themselves
