[QUOTE="helotaxi, post: 355634, member: 550915"] But, we, you and I, are not talking about the mass majority, now are we. We are talking about accuracy. Most anyone who would know group delay would not be asking about a $100 woofer, you are correct, but you started this post with a bunch of big words and said you wanted to discuss accurate bass and the merits of different enclosure types. That pretty much goes beyond the level of the $100 dollar woofer guys, so why bring them into this. In a ported enclosure, there is basically massive cancellation below the tuning freq. The driver is completely unloaded as well. Result: no output and a destroyed woofer to show for it. Now if all you listen to is rock and hip hop, then a ported enclosure might work well for you. The impact from the drums and the drum machines will be accentuated. It can sound pretty tight. It might give you the sound you want, but it will not necessarily be accurate. If you listen to classical or any kind of synth music that has really low frequencies (think subsonic here) then a vented sub will just flutter and will sound terrible and likely get damaged in the process. A 16Hz fundamental on a pipe organ will eat a ported sub primarily set up for rock/hip hop for lunch. A truly accurate system will reproduce it with correct tonal balance and with authority. The ported system will reproduce the 32Hz harmonic and you will think that the fundamental is there. It isn't. Psychoacoustics at work. There is a reason that most SQ competitors go with a sealed or IB setup. You want to talk SQ then talk SQ. SQ is tonal accuracy, dynamics, detail and linearity. You cannot honestly argue that a vented enclosure beats a sealed enclosure in all, or even most of those areas. Yes, there are sealed sub systems that sound like crap. There are far more vented systems that sound even worse. [/QUOTE]
