Dayton PS180-8: what to do with them

The frequency at which the response is 10dB down from the flat bits. F6 is also useful. These give you an idea of their bass reach. You often see F3 tossed around, Toole has shown it is meaningless to the human ear/brain. It is useful if you are using the bass rolloff as part of a filter (ie sya REL-stle subwoof). A vented enclosure will (typically) roll off twice as fast as if the box is sealed.

10 dB means it is half as loud. Anecoic means it will likely not be down anywhere near 10dB once you put it inot a room. In an extreme case, like the interior of a car, it will be flat or even have rising response.

Rooms are our biggist influencer in the bass.

Man I had to look that up "Anechoic". Showing off my Texas education. So as I'm playing with Xsim and the like should I be taken this into account? For example wood floors would reflect more sound back. I'd try to off set that in the XO and box. Maybe lower db level of bass... Maybe I'm over thinking this. Thanks for the help
