hmm yes i do also have listen to ACS45.1 before but i think it has been damaged so i don't really know well. ADA885 the bass is not so loud, but is deep, that's why i like it. it really goes down to 27hz (depends on the room) which is important for me. now i keep the ADA885, just upgraded to megaworks 550.
hi, well as always, with foobar2000 EQ i only encourage to increase the 55hz slider only. and you must click auto-level. thing is, im not sure about DA5000Pro, whether it has EIDC like Edifier C3 or not. because if it has EIDC, im sorry but foobar2000 will not be able to add much bass.

typically, this is what i used:


but with different speakers and different room acoustic, i can use other settings too. if you want more punch, try to relocate the subwoofer. do note that different room have different sound feedback. i.e. small rooms with thick concrete wall will cause the bass to be over-boomy. in this case, it's not the speakers' fault.

bump! updated first post.
