Blackstone frequency coverage

The low end on these speakers is 115hz. How can you cover the low end with these speakers? 100hz is the typical sub frequency but these don't hit 100! I'm concerned about how to round out the bottom with out needing an extra speaker.

Am I just supposed to accept this when. I get satellites?

    Yes, but you will wish you had a sub.

    a good small sub like the Polk PSW111 will have no probs reaching that so you wont have any hole as long as their all properly set up

    EDIT: oops didn't notice that you did not want to use a sub. I think with satellites, its really a prerequisite

    They are really meant to be ran with a subwoofer of some sort. You will want to place the sub close to the front running a higher crossover like they need. An Epik Legend would be a great choice as it can be crossed-over higher than most other subs due to it's design. 20-200 Hz +/-3.5 dB

    Check out this thread about a review. It was very impressive for satellites and a sub.

    I actually have a sub and don't mind using a sub. But subs tend to start at 100Hz and go down from there. This leaves some gap between the sub and the satellite. This is what I am concerned about.

    Furthermore, aren't sounds above 100Hz localizable? If so, isin't it a mistake to have satellites that don't drop down to non-localizable frequencies?

    I would listen to them before you start complaining.

    If you place your sub within a couple feet of your left/right speakers and level match it, you reduce the localization of subwoofer.

    Remember crossovers are not brick walls, if you defeat the build in x-over on the sub and run the x-over on your receiver at 100-120hz or whatever is it's highest setting you shouldn't have any significant gaps.

    FYI, below 120hz is non directional.

    Thanks. That makes a big difference since the TL3s -3dB drop off is at 115Hz. I found some review of the HSU VTF-2 MK3 showing the -3dB upper point at 121Hz. This makes me feel more comfortable about this combination.

    Debatable. I'd put that number more around 50-60 hz
    I'd say about 60-80hz for me. Once over 80hz, it is very obvious to me where the sound is coming from. I'm honestly not sure where the 120hz number came from, but the phrase "from thin air" comes to mind.

    Honestly, it seems like the number varies somewhat from person to person. However, I find it very hard to believe that someone could not localize a sound that is over 90hz.

    if you place the sub between the speakers, it'l be tough to localize. Don't worry too much about the number - I've played with the TL2s and they are excellent !! properly setup you can barely localize the sub
