    No the response is not poor. Tom linked the S&V article showing the 20-80 response was even better at a 4db spread, not 6.They probably added DSP to achieve that. And in bringing 20-25 "up" to match...it limits maximum output.I would like to see an absolute output curve without DSP. But...doubt you can bypass the DSP.

    But you haven't heard the Hsu and you are assuming you will hear some kind of distortion in that that you aren't getting with your current sub. IE you are attributing to physics that which is best explained by marketing. I'm not trying to be a jerk here Arjun, I'm pointing out there are assumptions and biases that we all forget we have but which are brilliantly illustrated by your post.

    Oh I'd bet there is some signal manipulation going on there. A little over 3 cu-ft, it would be tough to get flat to 20hz without some assistance. That's common though, all of our products have various bits of EQing here and there as well.

    "Might" be the accelerometer?

    Sorry, I'm a little lost here. Is this a reference to the Jamo servo circuit? Not sure what the question is?Tom V.

    To even out the FR.

    We don't know what you are talking about Arjun, please step back and write it in a whole sentence or something, we have no frame of reference. What you have quoted and your reply don't seem to be linked quite right.

    Oh okay, you are implying that the servo circuit in the Jamo might also be responsible for the signal manipulation to get the FR flat down to 20hz or so? Yeah, I suppose that is possible. Usually the "servo" is a separate circuit/loop in of itself but there are many variations.

    The end result will be the same regardless though(in terms of amplifier demand).

    It does actually have something called MFB that post 106 at AVS says does something to make it sound better than the HSU on particular music tracks.

    I believe most of the listening tests where two Jamo versus one Hsu.

    That should also be considered when comparing the two products.

    Makes the Jamo half as good?

    A real scientific test would involve two of each sub.

    I take my words back. I would not read any post comparing two subs to one as even remotely indicative of their abilities. This is not to say which is better or worse. I can only make a judgement when comparing one of each sub. If anyone has heard both subs they can make a better decision..

    Most of the time the budget in one of the top considerations when shopping for anything. In this case I believe the Jamo subs were on sale and you could get two of them for about the same price as one hsu. So everyone will need to make their own judgement on how to best compare these two products. I'm not even sure if the jamo is still available?

    What about a SVS pb 2000?
