Hi Guys!

This is my first post, so Hello.


I am very inexperienced and do not know what I need to expand my setup.


I live in a small apartment now and use a receiver with two JBL 880L speakers. Sound great, never need to put the volume over-5dba. really loud at that. Use a cheap sub woofer too. that does what i need. Im moving to a house and want to buy two JBL 830 bookshelves to use as surround on stands behind the couch. 880Ls in front of the couch L and R with tv mounted. I use for movies and music.


YAMAHA RX-V573BL 7.1-Channel

Now the big question is, is it worth it to get the two surround with the receiver I have. Will the two front channels be underpowered? I have no extra money for a new receiver. Whats the deal with amplifiers, i see my receiver supports it for the two front channels. And can someone please explain how the high and low frequency inputs work on my 880s? My livingroom wont be too big i just need to know if I made a bad choice with this receiver. I know amps can cost alot, and hope to hold off on buying one till i need to power the front channels in my basement in the far future when i build out my home theater.


Thanks in advance.

You should be fine with your receiver and the speakers you are planning on getting.  It is now driving your front speakers already, and there tends to be little content in surround channels.


As for the connections on your speakers, that is for bi-wiring (see your manual ), which is a stupid and pointless thing to do that many delusional people believe improves the sound.  Just forget about it, and use it as you have been.  Manufacturers put such things on speakers because some fools won't buy the speakers without them, and they do not hurt anything to be there (except that they cause a small pointless increase in cost).
