i have a 6th order in my s10 with 2 12's. it was designed by fallen at rcb enclosures and built by me. like many have said here if designed properly output will be awesome. oh and did i mention that the 12's are some 8 year old audiobahns!! and im only throwing 200 watts a piece. it gets decent loud.

There is nothing inherent about a 6th order parallel tuned bandpass that will make it shitty on music or lack bandwidth.

Well the group delay of the higher frequency ports can make them sound not very musical. The 6th order I built had a pretty flat response and pretty decent range but sounded pretty muddy on complex bass tracks on some bluegrass I was listening to. This will vary on design and driver but there really isn't a way to avoid a pretty high group delay in the 50-80hz range.

if that's your issue, i suggest reducing Qa. possibly by adding stuffing. next, ensure the resonance is out of band and not excessive. seems like a logical thing to do at least.

5th order(4th order bandpass with a low pass filter)

6th order parallel tuned(bandpass with the rear chamber ported while the sub is playing into another ported chamber...both ports are seen)

6th order series tuned(bandpass with the rear chamber ported playing into a front ported chamber...one one port is seen and its fron the front chamber)

7th order(bandpass with the rear chamber using a passive radar while the sub is playing into a ported chamber..only the passive radar and the front chamber port are seen)

8th order( bandpass with both the front and rear chamber ported and both ports playing into another ported chamber...only 1 port is seen but theres 3 ports all 2gether)

Ahh yes, was just thinking in terms of output, thanks
