[QUOTE="helotaxi, post: 361532, member: 550915"] First, and I have been holding off on this question for a while, WTF is WAVE BASS? All sound is waves. Tight kick drum bass is a wave. Fart sounding bass is a wave. The crash of a symbal is a wave. Were you in the recording studio reading the mind of the producer when he recorded the album? How do you know what he intended then? A studio uses a ported woofer system because they are working in a very large room when compared to the interior of a car. To get reasonable low end extension in a large space (relatively speaking) ported is the way to go. That does not make it more accurate. The only record we have of the intention of the producer at the time of the recording is *OMG* the recording. If the low frequencies on the recording are exaggerated and muddy, then rest assured that a properly designed sealed system can reproduce them in all their flacidness in the car environment. They will sound as they sound on the recording, nothing more, nothing less. It sounds as if you think that the enclosure and sub should add sound that just isn't there. THIS IS NOT SQ. It may fit your idea of good sound, but it also appears that your idea of good sound is measured in dB. The only "yang" here is coming from you. You have no clue what you are talking about and have hit rock bottom, began to dig and gone back and gotten a bigger shovel. We know about application specificity. For a pure, accurate sound quality system in a car, a sealed enclosure is almost without exception the best solution. If I needed to fill a stadium with sound, especially for live music, I would use a ported enclosure. Now if I wanted a accurate recreation of that concert in my car I would go with a sealed enclosure and play a recording of that concert. If the recording is worth the disc it was put on then my sealed sub will recreate it properly. Just because the orginal music was played through ported speakers at the time of recording doesn't mean that I need ported speakers to replay it accurately. A lot of the people calling you out ARE involved in car SPL! That is a totally different application. A pure SPL application with virtually unlimited power uses a vented enclosure. Why? Because the vented enclosure RESTRICTS the cone movement more at resonance and allows more power to be dumped into the sub. It also requires more power to get the sub to its excursion limits and to eek more output from it. It's really a good thing you aren't in the car SPL business.
