bandpass

I still have one of these, it still works, but I want to mess with it:D so I took it apart and noticed a few things: - there is no reflection damping inside (thought that was needed with a bandpass?) - the woofer is a DVC 8" 2x2 Ohm (and I lost the pic showing the markings...:mad:) I've been...

Hi all, newbie to the forum here. I'm working on a couple of small 4th order bandpass enclosures for a couple of 12" subs for my car at the moment (size is quite a constraint) and I'm curious about how the box sizes affect the frequency response. I used a 4th order bandpass enclosure...

hi everyone, prol a really stupid question, but im new to 3 way active. i have an alpine pxe-660: using it as a processor for a 3 way active front stage. my amps dont have band pass capability, just hp and lp. fine for tweets and sub. but not good for full range and mid bass. how can i...

My curent ongoing project is a 1990 VW Bus (transporter, vanagon, T3, T25... whatever you call it where you are from :D). The goal was to make a dynamic sounding system that is SQ orientated, but can play at quite high sound levels. The curent setup. Source: Intel Atom D2550MUD2, 2GB DDR3 ram...

All, Long time reader, first time poster. First of all, allow me to thank everyone for providing an outstanding forum for learning and research. I bought my latest project, a 2013 Scion FR-S, and as usual, the factory audio was sorely lacking. I was impressed with the factory use of 3 way...

Been looking for an SQ oriented 3 or 4 channel amplifier for a reasonably small system in my station wagon. I'm looking for a bridged 320 watts or more to power a subwoofer. I also require a subsonic filter or comparable bandpass capability for running ported. I'd like for feed not much more...

Long story short is that I'm building a 4th order bandpass enclosure for my car. My plan is to have the enclosure in the trunk and port the box directly into the cab through the rear deck where the 6x9's sit. The theory to my madness is to reduce trunk rattle and overcome certain issues with...

I was wondering if there would be a way to calculate spl of two or three different sound sources. What I'm calculating is spl from small bandpass boxes. I have to use bandpass because I need to vent the sound into the cabin of the car. I'm going to be using two or maybe three 4th order boxes to...
