It is impossible to know the various discounts available on all speaker brands but it is well known that Magnepan does not discount much at all, whether due to low margin to begin with or factory control, I am not sure. But I think this factor has a lot to do with Maggies holding resale.
The argument can be extended by (in theory at least) getting enough data on selling vs list price of all speakers when new. Then, compare the resale value of these at a future point in time, assuming (again in theory) equal condition. I am guessing the result of comparing used resale to new discounted price will be much closer (ie clustered) than you might expect for 80% of all brands.
Similar models can apply to the car biz. For years, M-B held up value as there was no discount available. Since they started discounting a few years ago, resale value has dropped and it varies by model, which variance corresponds quite closely to the selling discount by model.
