Hatsan QE backyard friendly?

So i am still very new to airguns. I now have a hatsan flashpup and a hatsan airmax. One of the main appeals that led me to pcp airguns was that with the right moderator they could be backyard friendly. So i bought those 2 assuming. The flashpup sounds as loud as a framing nailer and the airmax a smidge louder. I dont consider a framing nailer backyard friendly. A brad nailer maybe. Are there adjustments i can make to quiet them down but still be accurate out to 50ish yards? Or am i going to have to add a better moderator?
 
Though Hatsan's QE shroud quiets the bark a bit I never found any of mine to be back yard friendly. I put a Donny Ronin on my .25 BT65 & that worked. However it only worked when it was mounted on the shroud end, NOT directly on the barrel end. Made it LOOONG but quiet & even more accurate. Btw, I put a .30 Ronin on my .25 as suggested by Donny.
 
Thanks for tips and suggestions. I did forget to mention both are 25 caliber. Not sure if that would noticeably louder then the 22. I will try to dial back the speed a little before dumping more money into them for moderators. I was pretty bummed when i couldnt let my boys shoot it in the backyard because it was as loud as a 22 rifle. Does anyone else successfully target practice in town with either of these 2 guns?
