Real-life speaker measurement report!

Today I took a visit to a local pro audio shop in Riga – Discomania. The shop sells everything that is related to sound and light equipment and from many brands, but today we decided to have a look on some real budget speakers, since they are one of the best-selling ones these days.

I went to them with our hardware unit, the APEQ-2pro, a two channel equalizer, and everything I need for taking measurements. You can see my set-up below (move the mouse over the picture to see the notes). It consists of a laptop with software, an omnidirectional microphone and an external audio interface.

After one minute of measuring and about 30 seconds for the PC to calculate, we see the graph.

Well, as expected, it’s not anything fancy, but that’s where our technology comes to work. We generate an inverse filter and upload it to the APEQ-2pro unit via USB. The next measurement is taken with correction applied.

The result was great - a budget class speaker with a quite flat frequency response.

Then it was the next speaker's turn. The initial measurement looked like this.

As you can see, there are quite some problems with the high frequencies. It looks like the speaker itself isn’t able to produce that range because of the characteristics of its design.

Anyway, I decided to level it up and see the result.

Well, a lot better, isn't it ?

Here is how my set-up looked like.

We look forward to your comments!
