SpeakerCraft In-Ceilings Crossover Assistance, Part 2...

[Hillside Trece]

I'm still having issues -- and subsequently questions -- regarding my pre-installed SpeakerCraft in-ceiling surrounds which existed when we purchased our new house...I have them crossed over at 80Hz right now inside my Onkyo 605, but as a rule, should small in-ceilings be crossed at a higher number?

Should I bump this up to 100 or 120, or is 80Hz okay? It seems a little low for material being sent to the surround channels that are in-ceilings...

It doesn't hurt to raise the crossover to 90Hz, 100Hz or 120Hz. Try them and test the results with some familiar multi-channel music and movies and decide which crossover you prefer.

If you want to test it more scientifically, buy a calibration disc with frequency sweeps or download them and burn them to a disc. Test the speakers one by one. Set the crossover for the speaker at 80Hz, and then play the calibration disc. It will play frequencies from high to low. If the crossover is set too low, you will notice a drop in sound (a hole) when the frequencies get down to the point where the speaker no longer can handle the frequencies and the subwoofer has not started playing yet. Raise the crossover and run the disc again until you get a relatively smooth transition from speaker to the subwoofer.

Thanks Big Daddy,

Appreciate the prompt reply. I don't have a problem raising the crossover points inside the AVR to 90, 100 or even 120, but I was hoping for someone to tell me if there was some sort of "standard" for small in-ceiling speakers in terms of crossover point -- to me, 80 just seems "too low," does it not? I know Crackin' had suggested to me in the first thread about this that 80 didn't seem "too low" to him, even for satellite surrounds, but I don't know...

Wouldn't it make sense for small in-ceilings to not be set to 80Hz, being that none of these are really designed to dig down deep? I mean, I can understand setting small bookshelves to 80 because they may have some bass capabilities, but for in-ceiling directional speakers like my SpeakerCrafts, wouldn't seem logical that there needs to be a setting definitely higher than 80?
