Why I'm not adding a sub to my 2-way monitors for music

I’ve been fighting with room acoustics and a REL T9x for over a month. I was at the point of selling it until I went completely against the set up recommendations and moved it out of the corner, raised it onto a 1” granite slab and decoupled it with Herbies grungebuster pads under the feet. Now everything clicked into place, bass grip and definition, soundstage are spectacular. best of all, the relentless room resonance is gone. I don’t like the aesthetics of having treatments all over my apartment. If I ever get a dedicated listening room I’d be all for a different approach but for what I have to work with now, a sub is a phenomenal acquisition. I’m sure others are in the same situation.

I’ll just say that if you enjoy listening to monitors without a couple good subs, you either have crap subs or don’t know how to set them up.  My experience is that when you eliminate subs from a well setup system the soundstage collapses along with dynamics and it makes the sound feel like it’s severely compromised and almost broken and don’t wanna listen without the subs.  I’ve found this with full-range speakers as well, so it’s even more pronounced with bass-limited monitors.  But that’s just my experience.  There’s a reason Wilson and others use subs even with their $100,000+ speakers, so for you to say you don’t need them with some monitors — nah. 

Its all room and speaker dependent and room treatments and speaker placement.  I was going crazy with measurements.  I was able to get the Fritz Carrera Be to play -3db at 20hz and damn near flat from 23hz to 100hz in my last house.  
 

Its so room dependent and speaker placement dependent and if you aren’t taking measurements you’re pretty much shooting in the dark.

You definitely were on the right track by avoiding boost and cutting the peaks.  

Just curious how close your speakers are placed near the walls?  

I am not a total sub fiend but even though my mains go to 45Hz as measured, the two REL T9i I have provide the dynamics, impact, sustain, texture and hall ambience that make a big difference for me and my system. The  RELs are more subtle and musically accurate than other subs I have tried as well as being easy to integrate and they avoid coloring the midrange- all reasons why I like them so much.  

I own stand mounts as well as floor standers ,and by asd8ng a subwoofer - A Quality one ,two even better more even bass , the bass fundamentals just donot effect the low frequencies ,but also up into the lower midrange .

when setup properly the music as a whole is much more substantial as music 

as a whole .i  have been into audio for a long time and owned a Audio store fir 10 

years  and have had the opportunities to compare most every type of Loudspeaker type ,and setup in rooms . Whst ever you do is totally up to you ,but there is ample proof out there 1-2 subwoofers of respectable quality is a win win ..

svs 3000s has a great app to find tune your system , JL  Audio,  Rel , Kef , and several others are verygood.
