I've been working with the Amphion One18s for a couple of years and absolutely love them. Treated room, bass traps - didn't exactly put it all together scientifically but I have measured my mix position using Sonarworks to get a picture of whats going on. I have some adjustments to try with the bass traps at the front of my room (possible phase issues), but regardless my room is fairly large and the One18s have a pretty pronounced roll off beginning at 100Hz and then really significant below 70Hz leading to a fair bit of guessing.
This is leading me to contemplate using a sub with the goal of keeping the Amphions full range and bringing the sub up VERY subtly to just give some low end extension. The $5000 flexbase is not an option.
Curious of other Amphion users experiences with low end and whether you've tried adding a sub from a different brand?
I'm really interested in the newer Dynaudio 9S...

In the right room, they sound voluptuous!
I thought Johnken used a sub with his ?

Yeah - I use a cheap krk sub with mine - along with Sonarworks. Works great!

Try the SVS SB3000 if you have a dealer near you, I really like these things and have fallen for the DSP App. Everything I like better is much more expensive.
On the Cheap a Pair of Used Sunfire subs are still pretty amazing, I almost bought a pair then these demos showed up, I need to find 2K because I don’t want to send these back.

Also I know the crossover point needs to vary based on how your speakers interact with your room etc. but curious where you have your crossover set? Also do you keep the Amphions full range or crossover set with sub?

When I set up my sub, I just turned it up until my mixes stopped being too bottom heavy when I listened on other systems. Job done. Don't let it be overly complicated.

If/when you get a sub, I recommend experimenting with positioning, crossover, volume etc, and taking measurements with REW. It’ll take an entire day most likely, but it’s well worth the effort. I learned some very interesting things when I did that in my room. I got rid of a huge null by just turning the sub 90 degrees, so that it fired perpendicular to my monitors. I never would have guessed that on my own.
You can probably do something similar with Sonar Works but I’m not sure if SW will give you a waterfall plot.
Edit: I should add that in the end I chose the configuration that sounded the best, not the one that necessarily “looked” the best in my measurements. But I never would have got there without the measurements.

Actually, I just found mixes that I trust and love and turned it up until they started sounding amazing. Just FYI my volume is just barely up on the sub. If it’s a 1-100 scale it might be on 10.

I turn mine on and off. If the bass disappears in the mix without the sub then my mix won't translate to smaller speakers. I then resort to RBass or distortion to get the bass/kick harmonics up into higher frequency regions so I can hear it without a sub. I mainly use a sub to determine if there's too much flub and power in the low end, rather than using it to hear lower frequencies.
One producer I like once said that he "uses a 70hz high pass filter on the bass" because "there's nothing down there but mud anyway". I took that to heart and learned to get better bass tones without resorting to using ridiculous low frequencies.

Appreciate the replies! So, I have spent the last few days with the newest Dynaudio subwoofer the 9S (previous generation was called the BM 9S Mk II). I have a Sonarworks reference mic on hand but as you guys had suggested I have started with just playing familiar mixes and experimenting with different positions and placement and using my ear. I will spend a day with REW as well but in terms of overall experience the sub has made a huge improvement.
For anyone interested the Dynaudio 9S is incredible when sweeping a solo'd EQ band with a digital EQ and moving through the bottom end of a bass guitar or the mix (40Hz - 90Hz). I can hear things that the Amphions absolutely do not give me on their own. More experimenting to do but after spending a couple days with the sub I realized quickly I can not go back to just the satellites.

Fair point, I find in modern mixes though (country, rock, pop) there is way more information between 40-80Hz that gives mixes their depth and character. If using a plugin like ADPTR Metric A|B and solo'ing everything from 70Hz and down on modern mixes there's a fair bit going on and not just between the kick and bass. Granted the tone and character of everything is much higher as you said.
