Well...when I look at a speaker that is officially listed as having a - 3dB at 85 Hz, I think:
"Oh, it has no bass"
"Officially listed?" Oh, I guess from now on I should just go by what manufacturers "officially list" and not bother a) to measure and b) listen. Is that what you are saying?
Especially when combined with a tiny cabinet of limited volume, a small woofer, and a sealed enclosure.
Which is what I said at the outset: this has the makings of a poor sounding speaker due to those factor. My objective and subjective review confirmed that.
How it performs with a sub is not the subject of my review no more than it is with any other small speaker.
I asked for suggestions of budget speakers to buy and test and this speaker was recommended. So I purchased it and tested it like any other budget speaker. Now people know: it is not a proper budget speaker. And that it must have a sub that will sharply increase its cost. And aggravation in setup.
These are starter speakers. It used to be that this all we could do 30 years ago. World has moved on and we can do so much better. In this day and age I see no need to leave allowance for such. We know how to make excellent sounding cheap and small speakers now. I have tested a bunch.
I can't fathom those of you defending this speaker. To what end? Who are you going to tell to buy these over say, a low cost active speaker?
