Ascend Acoustics should be on that list. At the price points they hit, there are very few speakers that are engineered as well as them. They have proven quantifiable and subjective performance from 3rd parties. From a build quality perspective their crossovers are built to a MUCH higher standard than a lot of their competition. Overall build quality is excellent. As from a durability and quality control perspective you rarely hear of any issues with their products.\r\n\r\nI've owned several sets of speakers over the years but always end up going back to Ascend. I find their 340SE and 170SE to be some of the finest speakers for the dollar that I have found.
