[QUOTE="jonmrk, post: 183966, member: 547325"] I think that was probobly the most logical and intalligent post on this forum yet (including any of mine). First of all I would like to apologize for my term "crap". Obviously in the south it means less than other places. [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] To me crap = "not good as it could be" I am sure (as stated before) that there are many Alpine-R owners out there with well buit sealed boxes that absolutely love them. The post I orogonally made (along with several others) was not intended to degrade the sealed enclosures, but to simply let some people in on some inside information on what some pretty good size shops are having hte most success with. With a sensitivity of only 87db (SWR-1221D &SWR-1241D) a ported enclosure for some, would be very satisfying. But on the other hand, an Xmax (one way) of 13.35mm, sealed will do well also. You who have the time can debate this in another forum at another time. My problem is, when people make statements with no basis of comparison. I will gladly e-mail anyone a graph (though it will be out of car) between the two enclosures. But my recommendation is try them both for yourself. Don't listen to me or anyone else who is a "know it all" because there is no such person. Take the time, do the research and find out for yourself. But actually from a graph (take it for what it's worth), a ported enclosure at 2.5^ft tuned at 26 HZ has a better slope than a sealed (recommended 1.2 ^ft) from 70 HZ to 20 HZ. I'm done. Not trying to promote anything. Hopefully someone somewhere has gotten something from this forum. [/QUOTE]
