I have had Eric's fe167e monitors & 2 of his 10" BASH plate BR subs. The fe167e br is good, & is what got me hooked on Fullrange drivers. I installed Dave's phase plugs in the 167's & they are a big bonus, they do take along time to break in, just throw heavy , loud, fairly high power to em ..get your boat anchor out..his subs are good also for the money,, but bass quality, NOT slam..was the deciding factor in my letting them go. The subs are great for 80hz down, but any higher you will have problems. I listen to all types of music & many bass involved, so quick , clean & fast is a biggie for me, I discovered Open baffle & that is were I live..I dought you will beat Eric's fe167e for the money..Also PERFECT for small rooms...They also have 1"+ baffles so they are not junk, very tough finish that does not scratch easy..He packes extraordnary. My subs came by truck , triple boxed, & a custome OSB outer shell with a dang crate under. He uses solid -core hookup wire. I hint about Eric..He is life long friends with the boys at ZU...they have been doing audio together side by side since they were children. If you have not experienced the Fullrange way, this is a great way to get in.. & a quaulity product. & you can actually talk with the builder,, ..He is actually capable of building anything one would want..but his intro stuff is great for everyone. I would say if you are looking to use subs.. ask Eric to do a sealed version & use sealed subs.....Then down the road try Open baffle w/ a FR, & with bass augmentation..I did have the monitors on 100lbs filled stands & they will amaze, just hard to get the bass a s fast & tight as I want..
