Rockets for Den?

I do not know about the JVC receiver, it might be a little too low in wattage, but the room is small, so you will probably be cool.

I think you will be quite happy with that setup, have you thought about doing 450s instead of the 250s? For only $100 more it seems a no brainer...a good set of stands is that much.

Those things are too damn pretty to be outside!

Two potential issues I can think of.

1. These Rockets are HEAVY, pretty much industrial stength, HT equipment. Powering them with a 75RMS JVC is not advisable.

2. . These Rockets are HEAVY, pretty much industrial stength, HT equipment. Moving them around is not advisable

On the plus side, their tweeters are sliky smooth to extremely loud levels, so you'll have no problem powering a backyard dance party with them

How would a Yamaha RX-V995 which is 100w x 5 do with the Rocket 450s?

I think it will be fine, unless you like to really crank it up, then I would add an amp. I have a Yamaha RXV-757 hooked up to mine untill I got a Emotiva LPA-1 amp.

I had the Yamaha V2500 powering my Rocket 760s for a bit, I added 200W amps and for me there was a substantial difference even at low listening levels. Reference levels need more power but even at moderate levels, the speakers just seem to come alive.

My rockets were good with the V2500 but they were great with the separate amp.

The Yamana RXV-995 is a nice heavy receiver and powered my Rocket's fine.

I guess the next question is, will I be content with the 450s?

How heavy is the JVC? Thats your best indication of how large your transformer is.

The Rockets are not efficient speakers, so you need a decent transformer in that receiver....
