I did a search on this subject but nothing came up.I have a pair of sealed 12s I want to run in stereo with the front speakers set at small.the subs do not have an out for the upper frequencies so I cant go that rout.I was wondering if I could use the tape or aux outs or the zone 2 outs to run R/L subs in stereo and just use the subs crossover.I know I will loose the ability to use the delay and may come across phase problems.I am just wondering if it is possible.I do have a ported sub I am going to use for the lower frequencies that the sealed subs are uncapeable of producing(15hz).I am aware of the crossover problems I am currently working with that but it would be sweet to run the 12s stereo for music and use another sub to help out in the HT department.
