How should I calibrate my setup?

[bows3r]

Hi,

I have 805 diamonds in front which are 88db sensitivity and XT4's in back which are 86db sensitivity. Should I try to add some dB's to back since the 805's are more sensitive?

I tried XT4's in front and noticed that I had to put much more volume to get the same result than with 805's. Setup is Rotel RSP-1570 & RMB-1075 amplifier.

Thanks for answers,

Mika.

Ps. I use 2 channel with music. XT4's come to life with movies.

Mika,

A fairly simple and relatively inexpensive thing to do is get a sound meter. I prefer an analog meter.

You would then need some test tones to measure each spekaer output at the listenening position. This process will tell you whether to add or take away Db's for each speaker.


Many processors come with their own test tones. However, my experience is that good calibration disks have better test tones. And calibration disks also have video adjustments in them. So you could do a whole system.

Here are some links for products to consider. Hopefully you can find something comparable in Finland.

Moi Mika,

Marek Sound in Helsinki sells radioshack meters http://www.mareks.fi/tuotteet/radios...naloginen.html

You can also find spl meter apps for smart phones however these are not as accurate as the real thing, but doesn't hurt to try them out, right?

Hope this helps!
