So, while the PB13U sealed may be on par with the SB13U at 20Hz, it is 13dB louder in the 20Hz tune config... there is a reason people without enclosure size considerations still pay the extra for the PB13U
All the discussion has been helpful, but, alas, inconclusive... would somebody please loan Josh Ricci their SB13U already?!
i know that the pb13 is louder in port mode, i have done my research and plenty of it...you are simply missing the point.
"In terms of “value”, the SB13-Ultra is in a difficult price bracket. There are other Internet Direct subwoofers readily available that would likely rival the clean output of the SB13. Including the likes of the HSU ULS-15, Epik Empire, Rythmik Audio F15HP Direct Servo subwoofer, all at lower price points. Having said that, most of these subwoofers are larger than the SB13-Ultra (the Rythmik some 30-40% more volume and the HSU much closer at about 15% more volume after taking into account the wall thickness), and simply do not offer the same amount of signal shaping, amp power, and in some cases fit and finish that the SB13-Ultra does. Further, in the case the Epik Empire (and possibly other comparable sealed subs), we have seen that the frequency response of these sealed subwoofers have been modified and have a much steeper roll-off than the SB13-Ultra, almost like a ported subwoofer. At the end of the day, what you need for your own room and listening habits is really going to dictate which subwoofer is best suited for your particular application. In my opinion, once your room starts to get larger than 1,900-2,000 cubes, if you want reference level bass at 15-20Hz, either look at larger ported systems, or multiples of the smaller sealed variety.In closing, I did want to thank Audioholics for setting up this incredible and fun contest, and SVSound for allowing us “regular Joe's” a chance to review their subwoofer! Most of all, I have to thank Ed Mullen for his patience in answering all of my questions, I had lots as you can see from the above!"
This quote above is my point. all we can do is post the information thats available and go with that. i doubt anybody has legit direct comparisons between the e15 and sb13. You might be waiting for a long time before ricci gets his hands on them. why not just buy both and return the one you do not like?
