How many ways can you "invent" a speaker when you start with similar goals and use comparable designs?
Modern taste calls for tight bass down to around 50 Hz, high levels of detail, and wide dispersion. The vast majority of speakers currently sold fall into the two same camps: two way standmounts about 13 inches tall with tweeter over woofer (perhaps the tweeter is offset); and roughly 40 inch tall, narrow baffle ported floorstanders with the drivers in a vertical row (sometimes in a MTM design, and if the woofer doesn't fit the baffle its side mounted). Tweeters are nearly always soft domes and for a given price range, there is a limited selection of good mid/woofers available. Two recipes with similar ingredients should yield two sets of about the same old tired results.
Didn't Einstein define insanity as doing the same thing in the same way and expecting different results?
What intrigues me are unique designs. Single driver stuff takes the cake here as they push to develop enough bass; but other speakers like tweaky open baffles, VMPS extended range ribbon driver and CD lens, active designs, and TBI subwoofers are also interesting.
