I ended up getting a X-20 yesterday.(guy told me it would work 2 subs)Should come tomorrow.And I got the LFE-1 today.Total investment is like 130 or so.I'll try them both,but most likely stay with the m&k.Prolly put the other in my wifes system.Then everyones happy.Judgeing by pics,the M&K is alot better looking unit.
