Hi! new to the forums. been reading a lot, but lurking. just registered to ask a question. I'm looking for a receiver and compact woofer for my small 5.1 system. Currently running 4 NHT superzeros and a jbl northridge n-center. My sub is currently a crappy Aiwa powered sub. Can anyone give me a rec on a receiver and compact sub for this setup? Would an Onkyo Tx-sr307 suffice? My budget is $300 for the receiver, and $150 for the sub, but cheaper is always better. thanks!
