I have a stupid question...
If I measure one speaker in room with an RTA, everything measures fine.
If I measure the other speaker in room, it measures almost the same.
If I measure both speakers at the same time, I get destructive interference from around 900 to 2.3 KHz. Strange.
I've already tried the following:
1. Check the crossover. Fine.
2. Check speaker impedance. Both are identical.
3. Check individual speaker FR. Both are identical.
4. Connect both speakers to the same channel of my amp. Same result.
5. Move speakers closer to one another. This does help. The closer they are, the less interference there is, until finally, it disappears and measurements are flat again.
I'm thinking that measuring both speakers using an RTA is creating destructive interference from 1 KHz on up. Reason being, one needs to place mids and tweeters as close as possible to the woofers for them to sum up, so, can I assume that the distance between the speakers mean it's impossible to measure both speakers simultaneously with an RTA?
Or, is it something else? Can stereo speakers be measured with an RTA? Should I still keep looking? for a solution?
