I need to pair speakers with semiconductor amplifier but not matched. Please advice me!

Visaton bg 20 + visaton bg 13 p + visaton dt 94.

Sensitivity 92 db. I listen to jazz and country music should match what li reasonable for the capacity of the speaker. Please teach

The problem here is that when the sound of bg 20 will be interrupted by the sound of dt 94 and power amplifier will not be enough to download all 3 speakers, the sound will be very dazzling and difficult to hear, I need help on amp

No, I don't think so. But the BG-20 is meant as a midrange driver (so says Visaton) and isn't going to have much bass, unless it's in a rather large box - like 145 liters. Add to that the fact that it has a lot of midrange response, and your going to hear a lot of midrange, it will overwhelm the bass. You just have too much midrange coming from the BG 20 and the DT 94. The crossover needs to correct that.

You could try to make it work with a better designed crossover, or you could replace the BG-20 with a real woofer, and a better crossover.

I agree with your comment. Maybe I have to replace bg 20 with subwoofer to get bass. With 38hz, can not be better!:sad:

Visaton Drivers? Not hard to run this combo up the flagpole! 😀

With no effort to optimise at all, it looks promising. If a bit bass light. Which is fine for Jazz and Bluegrass. Nothing awful in the impedance. Most amps could cope with that. 😎

Thanks System7 for your design. 🙂

I *fear* Miss just connected all 3 speakers in parallel, maybe used a small cap in series with tweeter, that´s why he´s finding the (now very low impedance) cabinet hard to drive, too midrangey and bass shy.
Hope to be mistaken.

Just the BG20 alone , with its whizzer cone, can be a decent full range speaker ; a real tweeter will extend range upwards; hope that midrange speaker both is fed from a proper crossover *and* lives in its own tiny isolated "cave" , away from woofer backwave pressure.

Miss -

Is this a commercial speaker ?
Or is it a home built design ?
What size is the cabinet ?
Can you show us the crossover and its schematic ?
Can you describe to us just what you think is wrong with the sound ?
What is the rest of the audio system ?

The more information you give us, the better the help that can be provided.
