Hi Bernard,

I did several mods including internal cabinet / bass driver dampening, experimenting with various weights on top of the bass module, adding Mapleshade brass cones to the speaker, and adjusting the vertical rake angle of the speaker. All were significant individually. The aggregate improvement, for minor dollaras, was very impressive and well worthwile.

Go to the search mode and see if you can find.

If you can't, I'll provide details.

Bernard,

No I didn't. But if you get into the bass cabinet, you can vary the amount of "batting" you put back in, which changes the "Q" value.

If you'd like to see just how far one can 'mod' an SL3, please click on my SL3XC element in my sig.

As for mods, upgrading caps and stuff is a good exercise if staying with passives. The other mod I'm eager to do is to upgrade the ESL audio transformer. The stock one has pretty serious HF roll-off that I can see without the factory x-over in front of it EQ'ing.

Gordon - I searched but couldn't find your SL3 mod posts.
I'm interested to see if they can translate to my Ascents. Can you point us to them?

Thanks,
Mike

Jon your mod is very impressive to say the least ...!
I was thinking of opening the cabinet and reworking some of the passive components ...any idea which ESL transformer might be a good replacement ?

GG I bet Holly C was good !?
