My Sonus Faber Amatis have weak bass even though I'm running ML 536s--800 w/ch into 4 ohms


I don't know what I'm doing wrong. I thought the new monos would solve the problem. I still have to use subwoofers to feel like my system has any bass. I've tried speaker placement but to no avail. I realize it could be room issues, but short of packing my room pull of room treatment, there has to be something else. The drivers work, it just doesn't sound full. Should I get a different speaker? At this price, I expected more.

I don’t know if anyone is following this post any more, but i solved the problem and the bass is so much better. Finally what  was expecting, and I don’t even need the subs anymore. I just coupled the speakers to the floor instead of isolating them. Seems too easy to have worked, but it made 1000% difference. 

Glad you solved the problem. What were the isolating and coupling solutions you were using?

@torke Glad you we're able to solve your issues.  Which isolation footers did you have before and when you decided to couple them how did you do it?  Are the speakers on spikes now?  

There is another thread discussing footers and isolation here... https://forum.audiogon.com/discussions/footers-under-new-speakers

I made a comment about how isolation or vibration de-coupling may do more harm than good when it comes to bass weight and impact.  

It was a Herbie’s Audio product, which I’m sure is good for some  applications but the more research I did the more I realized I needed coupling, not isolation. I have hardwood floors glued to a concrete foundation. Anyway, the speakers are on the OEM spikes that are resting on 36 mm spike shoes that cost me about $90. Cheap fix; world of difference. What’s funny is that I was about to spend a mint on ISO-acoustic feet, which would not have solved the problem.

 

If anyone is interested, you can find the spike footers on Amazon
