Why Don’t You Post Your System on Your Profile?

Hi Kota,

Yes I wish I could describe how amazing the sound is. I’ve never seen DSP results like this before. I didn’t come close in my old room. It helped using the processing power of my computer I built. I let it run for 30 min at a time working on creating the filters. I played a lot with the settings in Multi Sub Optimizer to get this result. The secret to getting the system to fix these issues is using four subs + the main speakers when measuring and then the mains are running full range and the DSP is applied to the subs which are strategically placed (they are running full range as well). The only way to fix the room nodes is with multiple sub woofers, traps can help but only so much. The other key here is that the dspNexus is running at 192K which allows for a lot more flexibility than processing at 96K. The system has hair raising realism at this time. I haven’t heard better anywhere. The process is a pain but once complete you don’t have to mess with it until you move. I’m looking forward to having some friends over to listen. My dad is visiting now, he’s a trained concert pianist, and he can’t believe how perfect the system sounds. We’ve had a lot of fun pumping out classical, rock, alternative, dubstep, you name it and we have played it, everything is jaw dropping. I will say that this system is very unforgiving on poor recordings but even older recordings that are mastered well sound great.

Thanks,

Steve

That’s what I call a "budget worthy" component, when it can transform everything. Also interesting that you are running everything full range instead of using a crossover on the mains. Earl Geddes recommends that in addition to multiple subs. You get a result like this and you simply lose all desire to change anything. You know  changing gear will be different, but why bother. I think having a dynamite FR in your room should be mandatory in this hobby.

Thank you for the compliment, it has taken a long time to get this where it is. I really wouldn’t change a thing except one day to get a pair of Clarisys Auditorium speakers. I heard the Minuets at AXPONA and was blown away. I do have a crossover on the main speakers on the highs/lows each has its own channel with the amps vertically bi-amping them. It is unusual that I don’t have a hard crossover on the subs but they attenuate themselves due to their limited range. Yes I wouldn’t change a thing really. I learned a lot in these forums and to piece meal information together to actually execute the idea of an active system was not easy. Hopefully my documentation can help others who want to try. It’s certainly a process and the results are incredible. There are some amazing people who make this all possible namely John Mulcahy who created Room EQ Wizard and Multi Sub Optimizer and keeps them updated and responds to people personally on AV Nirvana. He is a champion of our passion and should be lauded for his dedication to promote and encourage people in the audio world.

If you had to start over what would you do first, second, etc?

I just uploaded my HT system on my system page.  My HiFi rig has been posted for a while now.  I update my HiFi system as I make changes.  I know some leave their older system pics posted so others can see the progression over the years.  I tend to just move on.
