Just placed an order for standard black M60s and a VP160 center. I'm replacing Energy speakers from about 15 years ago that were much less expensive. I hope I have an immediate WOW factor!

I'm using an old Pioneer Elite receiver (120 watt at 6 ohm; $2300 MSRP in 1999). However, I use an OPPO 103D Blue Ray and send signal to the "decoded input" on the receiver, basically making it an amp. The OPPO has all the modern deciding, so this works great. We listen to music and will use these speakers for surround sound.

My questions:
Should I also buy a subwoffer? If so, should it be ported or sealed? Any suggestions on make and model that would fit my new speakers? I have a very cheap $100 subwoffer that I've used for years, but I'm sure it won't help these new speakers sound great.

Thanks everyone! I'll let you know my thoughts on the M60s as soon as they arrive. Now the big wait...
