Ive got the bass on the NEC A-710 integrated turned all the way up (+5, so Im guessing +5 dB at their selected frequency) and have been switching bw A, B and A+ B speaker settings. I really am impressed with the sound of these! I can turn the volume knob to a max position of 9:00 before they start to clip. While it would be nice if it went a little louder, I think I can improve things by adding a self-powered sub and turning the bass down.
// the A-X5 has the door, it was just down(want to rig something up to help hold it shut better). It even came with the owners manual but I left it there lol. Yeah I really like the sound of the A-X5. Would love to hear a A-X5 or A-X7 since I wish my A-X5 had just a bit more power.
/// added a cheapy-from-the-thrift Aiwa TS-45 powered sub to the mix and that definitely helped out. Enjoying it for sure and getting my money’s worth out of all the speaker outputs. Speaker A is doing double duty for the sub portion of the jvc as well as feeding the Aiwa.
