Large speakers plus EQ, what have you done?

I just purchased a White Instruments Model 4856 graphic equalizer. I only set it up Wednesday so I can't say much about my satisfaction with it. I'll be playing with it for a few days. 

I can tell you it's extremely quiet. I tried a Schiit Lokius and found it produced both hiss and hum, so I returned it. The White added no detectable noise. 

White Instruments was in high end studios for decades. I think they are still in business.

A little follow-up. A few months ago I tried using a HPF and sub to deal with my low end issues. That was pretty successful below 80hz, but I still had other things I wasn't satisfied with. I bought the White EQ to work on those. But I eventually realized I could take a different approach and use the EQ to deal with all the frequency issues. Today I worked on that and essentially eliminated the need for the sub, although I'm still working on integrating it below 40hz. 

My speakers are stand mounted but do have a pair of 12" woofers that put out plenty of bass. I resisted using an equalizer because of potential phase issues so went with the HPF and EQ on just the low end. But the White Instruments unit has excellent phase coherence and I'm not hearing any smearing or imaging issues. I'll continue to tweak, cause that's what I do, but I'm pretty happy with what I'm hearing.

I have 13 bass traps and several diffusion panels in a 10x13 room. Using EQ is a last resort for me. I've been working on my room acoustics for 2 years, trying all manner of controlling low end, but there's not much I can do below 100hz. The HPF and sub was one approach, the EQ another. 

But there were some modes that really hurt the vocal sound and the eq fixed that. I don't consider it a permanent solution but it gives me a reference to compare other speakers. Before this, other speakers sounded so dramatically different, there was no realistic comparison.
