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.

Explain what the exact problems are. Are both speakers not producing bass or just one?
What amplifier are you driving them with, could be underpowered??

Don't change woofers unless you are prepared to redesign the crossover.

If you really want more bass, I suggest having the woofers' T/S parameters measured to see if it's feasible to port the cabinets. Otherwise, woofers that give you "more bass" in a sealed box will also be lower in efficiency, necessitating a significant crossover modification to restore correct balance between the woofer and the other drivers.

The easier solution is... get a sub and use it to gently augment the low bass region.
