Dunlavy SC-IV bass problem


Hello,

please help that I bought a Dunlavy SC-IV speaker. But, I found the bass of the speaker is not enough. It seems missing some range. I am sure that the speaker driver (Vifa) is work well.

Can someone explain bass problem of Dunlavy SC -IV and teach how to modify it to new version(to use scan speak woofer driver)?

Thank you.

Hello all,

I am using Accuphase power amp P600 and pre amp C240. I think the power of amp should be enough.

The speaker is bought in second hand shop. It is like new. I trust there should had no user to modify it before.

Can someone give me information to identify my own one?

As for bass response,

1) I found that the sound of mid and high driver is louder than the bass. I just hear the mid and high driver. I need to tune them down and then the bass will be better or more bass I heard.

2) I feel some stranger in bass range. It seems missing somethings but I do not know how to say that. I need to open it to check is the wire out of phase? However,

Before opening it up, I would like to point out that both side speakers are same sound quality. So.........

My friends and I feel problem in bass!!!! But, I can not find other users in Hong Kong to make comparsion.

Can someone instruct me how to do it?
