Hi there. I am new to the forum and was hoping I may get some advice. I am using my old Technics sadx 950 as a power amp from my Pioneer vsx1015. The reason is I have a pair of cv vs120 that are 4ohm. The Pioneer seems to handle 6-8ohm. Is there a problem with using a 5.1 reciever as a power amp in this case? Thanks for any response. Kind regards.

If your AVR is not 4ohm stable it's probably not a good idea to power your 4ohm CVs with it. They will dip below 4ohms with certain frequencies. You might be able to do it at lower volumes but if you turn up the volume you will probably throw the receiver into protect mode.

Thanks for the reply. The Reciever im using is a Technics Sa-dx 950. It is capable of using speakers with low ohms and I've never had it clip once nor have I blew the fuse in the speakers so far. The Technics is what im using to drive the speakers but its in the preout of the Pioneer. Its seems okay thus far so hopefully time will yield the same 20140312_150931.jpg

Cerwin Vega noob here. I just got four sa 140 bookshelf speakers and none of them work even with wires ran straight to the drivers out of the box. do these take a certain signal?

No, they don't take a special signal. I'm guessing these are used speakers? If none of them work the problem is either with the speaker or the source provided to the speakers. It's possible that all four speakers are blown. Especially if you've tried connecting power straight to the driver. As long as your amplifier works and you have a source playing they should work.

Well, the cones move freely and yes they are used. So they're probably burnt out/ blown.

If you carefully move the cone by hand and listen and feel for a scratchy sound or feeling. That's an indicator that it's blown. It can still be blown without feeling or hearing that.
