10" Type R in TCAB - Freq response - vid
Something that has been requested is for a vid showcasing the frequency response of one of the setups... they are proven to get LOUD, but what about the frequency response, your typically peaky/loud setup?
Well, here is a vid showing the frequency response of an alpine type R 10" woofer in a 2007 toyota yaris LB in a typical TCAB Classic design enclosure. Power is from a cadence z8000 amp - but of course the test was done at low volume. The mic was on my lap in the drivers seat, facing toward the front of the car. This placement was easy to film Vid also upped to realm, and a graph is in the works. http://www.youtube.com/watch?v=PJSzrzOOcqM The response is very satisfactory - although the type R isn't the "tightest" sounding woofer, the response of the box makes it an awesome rap/etc setup. |

do you want the cut off that low? or is that ideal when you have your mid bass set up right and everything?

Right now the deck xover is set to 60hz (as can be seen by the slow roloff) and the amp xover is set to 75/80hz... it shapes the xover well for my particular uses. That being said, my midbass (stock - lol) can't keep up... its just that I prefer the sound of a low x'd over sub... this is another reason why I like the type R - it doesn't offer much beyond 50hz (as can be seen by the slight dip in the graph). I design to compensate as much as possible for the R's shortcomings, but it is what it is. As I've experienced before, the 10" R exhibits a big fat impedence rise and is tough to get power to. I'll have some more test data (actual power, actual impedence) soon... along with a comparison to a sealed box, and a prefab ported box. |
