I would be interested in a test that compared an entire lineage within one companies history. Let me explain. I would like to see how a major brand like Velodyne has progressed over the years. Let's pick a level in the Velodyne line (top of the line is probably the easiest to define) and compare the products from various vintages. For example compare a ULD-18, HGS 18 and a DD18 (and any other top of the heap 18 inch models that they made). It seems to me that a lot of the progress in subwoofers over the past say 20 years has been related to making smaller and smaller cabinets. This requires ridiculous amounts of enginering and cost (multi thousand watt amplifier and drivers with 4 inch peak to peak excursions are tough to build for reasonable prices). Some of the "discount" sub brands like HSU and SVS seem to be doing very well building models based on the model of the old Velodyne ULD's and Snell SUB 1800's. Build a big enough box and even a relatively tame drive with only one or maybe two inches of peak to peak excursion with a "small" 300-400 watt amp can still pound out the bass and have reasonable sound quality to boot. Let's seen if those of us still holding on to our old subs have lost our mind or simply are willing to devote a bigger swath of real estate to our hobby.
