And for the lazy here is a summary:
"
The RS drivers are not perfect but they are pretty good for the money. There are a lot of distortion components that are -50 and -60 db down or better where the fundamental is above about 100 Hz at least. Below 100 Hz -40 db is more typical but that is still a very good result for lower frequency where the cone excursion is higher. These results are not $30 ~ $40 driver territory. This is $100+ driver territory. These drivers look great and measure great. Just listening to them on the tone generator they sound very pure so I have to think they will sound good on music. I'm planning to build several projects using these including a low cost dipole. I'm also planning a number of conventional box speakers. For the money, these drivers are going to be really hard to beat. Dayton really out did themselves this time. Way to go guys.
It should be mentioned that any rules of thumb you may have about cost of associated drivers will be skewed by these. If like me, you would normally choose a $20 tweeter to go with a $30 mid-bass you will end up with a quality mismatch. Until an "RS" tweeter is introduced that can keep up with these you're going to want to spend probably double of the mid-bass to get a matching tweeter. So, the RS line is not a total solution for building an inexpensive system it's just a way of reducing the cost of a more expensive system. Hopefully an RS tweeter will arrive soon and will live up to the RS line quality to price ratio. If so then you will have the ultimate solution for a very low cost speaker with high-end performance.
