Not to poop on Paradigm's parade, but I find this confusing that 2k pair of large towers rated at -2db 50hz and a cheaper large bookshelves (BMRs) claim to have -2db 34hz bass response.
Am I missing something here? (besides the obvious difference in sensitivity)
Haven't I been hammering away for years that there is an inverse relationship between sensitivity/efficiency and bass extension? Remember that?
These paradigm speakers have a 92 db sensitivity and the BMRs only 85 db. So the Paradigm is 7 db more efficient and that is a lot.
Not only that the paradigm will have a far better power response across the mid band as they have a 6.5" mid driver.
This BMR uses this
Tectonic unit that only handles 20 watts, with poor sensitivity. So I know I would run those speakers out of gas and almost certainly be tired of replacing them by now.
Those units are interesting though as they have a remarkable frequency response. Those units were actually developed by no less than Peter Walker. He was working on them as he got to ill to work any more and sold the patents. He never intended that you would use one per side however! His plan was to make units cheap enough so you could make panels of them. He envisaged 100 or more per side, all packed close together.
I have long had a hankering temptation to do just that.
The real power response per frequency band is something seldom measured, but should be. It is something I'm very conscious of in my designs, and is one of many factors that make for truly realistic reproduction considering the very wide dynamic range of many sources.
I can be certain those paradigms have a far better power response then the BMRs.
As far as the Pardigms, with receivers getting still more miserable, I think Paradigm were right to give weighting to high sensitivity. The only thing troublesome is that dip if impedance after tuning frequency associated with a very negative phase angle. I find that odd and I think Paradigm should investigate the cause. It is not something I would expect. Worst case scenario it is associated with some unexpected resonance in the crossover components, but that would be unusual given how far away it is from a crossover point. For the market these speakers are aimed at, it would be ideal if that could be tamed.
Paradigm speakers have not impressed me previously, I have found them brassy with an over tubby bass. These speakers measure very well, and I have feeling these speakers are a major upgrade from previous offerings.
I would say it is well positioned for the requirements of a lot of customers in the current market.
It seems subs are now pretty much universal. So bass extension becomes unimportant. The problem is that most bookshelves do not have the required power response.
I have designed a system for an area of out new home we are embarking on for my wife. It is in wall and highly compact. F3 is 80 Hz for for the front three. It wall have an awesome power response. Sub will be in wall TL. I'm quite excited about it. It models very well. The sub is the only bit not compact. The front three are pretty small.
