Your sub experience: Easy or hard?

Two Hsu subwoofers - using one to handle 90hz and below with Quad ESL63s and a smaller one in my recording studio/office with JBL 4401 monitors (old school).  Very easy integration. Both sound great. Transition between the mains and subs can’t be heard. And taking the low end load off the ESLs opened them up even more and lets me push them a little harder, when needed. 

If was difficult at first. I tried to follow the manufacturer’s suggestion in the beginning which was a good starting point, but once I started listening to what pleased me sonically that’s when the magic happened for me. Everything became enhanced highs, mids, and of course bass. 
 

Good question, Erik.

I'm running two JL Audio F110s with auto room optimization, which is the main reason I say sub setup is very easy. The JLs are active and non-ported so they work pretty much anywhere I put them. The ARO adjusts for room modes. I also run a JL Audio CR1 active crossover to set the LPF & HPF, which I think is also a reason why my subs are so easy to integrate. My speakers are Magico Mini MkII, which sound great on their own but the subs add a lot of dimensionality and grip. 10/10 would recommend. 

Great topic. 

I have been running 2 REL T9is for a few years.  Setup, now, is a breeze.  I could turn them off and reset them and have them integrated again in 15-20 minutes or so. At first, however, I had trouble because I kept fussing with them.  As I gained more experience, I picked up more intuition and my ear got better trained. 

Disclaimer--I only use them to bring out the lower octave or so. I have them tuned so they are not particularly audible.  

The difference with the subs is remarkable and I would never go back to not using them in this setup. 

Gotta point out that choice of sub used is key. The right sub is one that is designed to supplement your mains as needed. If monitors with limited extension you might get away with a smaller sub needed to fill in the low end well. If larger near full range speakers you will need a bigger more extended sub to do that. Room size also matters. The bigger the room the bigger the sub needed. Sub should have level and roll off adjustments at minimum. Phase is a big help for placement flexibility. Very important to look at sub frequency response specs to identify good candidates. It’s almost always about filling in the missing low end. So be sure to lock the right solution for the problem which is different case by case. From there it is not hard. Otherwise, may be impossible.   To get good bass more consistently across the room multiple subs might be needed.  For just the “sweet spot” just one may do fine.  Gotta have the right overall integrated design to start.  I suppose that part can be somewhat hard. Good luck !
