Dunlavy SC-IV minus SC-I = a good sub?

The bass out of dunlavy 4 and lower is weak anyway I think. You have to go to the 5s to get any real bass

I think I did not do a good job of asking this question.

If I add a sub to an SC-1, which used lets one try the Dunlavy sound for a few hundred bucks (and less than a hundred shipping), I am afraid that the area between 100 Hz and 300 Hz will still be deficient of bass, and so an SC-1 plus a sub will still be much more lacking in bass than an SC-II, III, or IV.

Maybe nobody is answering because they are embarrassed for me for asking such an easy question. :-)

No, the SC-1 with a subwoofer will not give you the sound of an SC-IV. As far as bass output, it has a lot to do with the room, equipment and the person setting up the system.

I was a Dinlavy dealer back in the day. We sold very few SC-1's. Mainly for surround channels or for owners who already had the larger Dunlavy speakers and wanted a smaller monitor speaker for a smaller room.

The SC-1's with sub will not only have less bass, but no where near the BIG, FULLNESS of the larger models. The SC-2/3/4 are large speakers. Tall and pretty deep cabinets. Very dynamic with a large soundstage.

Will the SC-1 with sub give you "taste" of the Dunlavy sound? Sure, but nothing like their bigger brothers.

If you have the room, the SC-IV's are truly outstanding. The SC-III's are probably my favorite of the bunch and fit better into most rooms.
