Want to add 2 more speakers to stereo amp- CXA80
Thank you raysmtb1 but I believe this article goes deep into electrical formulas and what have you for an amp that does not have additional speaker options.... my Cambridge CXA80 does have A, B and/or A/B speaker option for a separate room. Do you have any advice on my questions above, or does any other Audiogon viewers have some friendly advice for me? Thanks! |
If you want all 4 speakers playing together the load on your amp will be to low and the amp will most likely shut down. That CXA80 has preamp outputs. You can run a power amp and hook up the ceiling speakers to that amp and there will be no problem using all the speakers together! Something like this for the ceiling speakers would work! https://www.parts-express.com/Dayton-Audio-APA150-150W-Power-Amplifier-300-812 |
Yogiboy, so my amp has a setting for a separate room option for 2 additional speakers... but I can only play 2 room at a time, not both rooms at same time? Is that because the ohms are different on 2 sets of speakers? Will the SQ on my towers be reduced with a 2nd room set up, if I’m only playing the tower speaker room? Thanks. |
You will have no problem if you play one room at a time. If you want to play both rooms at the same time you will have a problem. The reason I showed you that Dayton amp is because it has a volume control so you can match the volume on both sets of speakers when you want to play both at the same time. You can use any power amp but you should find one with a volume control! |
