[Dormie]

i have advent/1 + sansui sp3500 3 way with 15"woofer

on denon receiver, experiencing some clipping

the denon ran the advent/1 + sansui sp2500A with 12"woofer fine

how many wpc do i need to run these 4 speakers

You are probably running them in parallel with a 4 Ohm load. So, first you need a receiver or amplifier that is stable at such loads and probably lower. I'm running 200 watts per speaker with four New Large Advents, but only in an effort to gain "dynamic headroom" not ungodly SPLs. What is the power rating of your Denon?

wired in parallel

denon DRA325 40 watts/channel

with toshiba SA-420 receiver 25 watts/channel

drives this no problemo

the toshiba also drives sansui sp3500 with 15" woofers

+ sansui sp-x6900 with 12" woofers together in parallel

(to satisfy my wood lattice grill fetish)

I believe the Denon DRA 325 has pre amp outputs which means you can add a power amplifier to gain more power. SLA ART-2 and Behringer A500 are a couple of inexpensive pro audio amps that many people are incorporating into their home theater set ups. Otherwise, a good home audio stereo power amp from AudiogoN is a possibility.
