A lot of people concentrate on fronts but I have found that by reducing the rears power and range slightly enhances the sub in in boot and improves the lower frequency and omni directional effect to the ear. I am running rears mid to low approx 75 hz- 14Khz at a slightly reduced output compared to the front mid drivers and the higher frequencies concentrated around the front tweeters.Sub running between 30 - 70Hz .Still trimming slightly with DSP but sounds awesome just preference tweaking as I am driving out more with more intense listening !
isn’t it always the way…
Did you go with the Helix amp set up - Mk1 or 11 …
