There's a lot more bass in a 6.5" driver than most of you think

Unexpectedly, however, I did notice an improvement in my system’s midrange clarity and the level of detail within the soundstage illusion, too.

I literally just read a posting that explains this. Look at the comments from Dr. Kippel:

I quote him below:

For the same reason amplitude modulation (a bass signal f1< 100 Hz modulates a high frequency signal f2> 300 Hz) generates much more differences than phase modulation, aka Doppler).

Of course, it is possible you just had higher order room modes too. :)

I’m currently hesitant to add EQ to my system since my system currently just requires adjusting the cutoff frequency and the volume on my 4-sub DBA bass system’s sub amp/control unit, I don’t believe it’s necessary for bass improvement in my system/room and I believe simplicity is a benefit.

Honestly you’ve done plenty, besides, doing EQ correctly requires a great deal of measurement and fine judgement. I’m not religious about adding EQ when none is required either. In my own space I have a lot of GIK and have lived happily with no EQ until recently adding Roon. The EQ changes I’ve made anyway have been pretty subtle. Now play some Holtz or the sound track to Battlestar Galactica. :)

Hello Erik,
     Thanks for the audioxpress article, very interesting about phase and zero phase in recording and playback. It seems like the effects of phase linearity and accuracy are subtle, also.  
     Yes, I liked dealing with Mike Major of GIK on my free room analysis and I'm very impressed with the effectiveness and quality of their room treatments thus far.  I'm very optimistic about the detailed room treatment plan I created with the very capable assistance of Mike.  
     Phase one was the installation of the stacked GIK Tri Traps in all 4 corners and some GIK 244 bass trap panels along the front and rear walls.  Phase two will be having a local Indianapolis hi-end shop, The Audio Solution, install the remaining 12 combination of a balance of absorption and diffusion midrange/treble frequency wall panels throughout my room, with the strategy being mainly diffusion at the front and rear of my room and mainly absorption in-between.
      I'll probably start a thread of the perceived results in a few weeks.  My intent will be to just be honest and describe my impressions as I hear them.
   Thanks again for your honest and useful advice.

You are welcome. One thing I like about Toole a great deal is we hear the same things. Others may find phase and phase linearity big deals, and for them it might be but after lots of listening to Thiel and Vandersteen it is not that big a deal for me. I was thinking of playing with rePhase and Roon to attempt this digitally, but after reading that I'm going to forget about it.

Thanks again for your honest and useful advice.

My pleasure. Glad I helped, I envy your ability to get so much gear installed.  Much more than I can do in an apartment.

Happy Saturday to all...*S*

Hey, Eric...this appeared in the 'cunning trick' forum...

...and I thought you'd enjoy it.  The speakers shown over a major mix board may be just a 'trade trick' (sic), but it definitely fits within your proposition. ;)

Cheerfulls, J
