Eminence 15 LFC 4 ohm

TH, TQWP, T-TQWT, & RLH are BP6 type enclosures.
FLH & BPH are BP4 type enclosures.
Notice how the 150 liter TQWP looks like a series tuned BP6.

So does the bandpass order directly correlate with what freq. band that type of enclosure is "tuned" to or is it more just to define a physical difference in design?

And, if you don't mind me asking, what do you mean with "series tuned"?

Both.

Thank you, all these different terminologies are confusing at best!

Sorry last question but could you also recommend and books i could buy to get me stated on the subject as its all terribly overwhelming without any real reference.

Thanks

That 12volt link in Post #23 has a TON of links regarding subwoofers, including books.

I actually have some of the earlier David B. Weems books at home. I couldn't remember his name here at work. I was thinking David WeeBs...LOL! I think I got most of them at Radio Shack which are no longer listed on their site. I got the books in the early to mid 90's. I do try to scope out speaker books at Barnes & Noble from time to time.
