Crossover frequency setup

ver01@ · 18 Apr 2019 at 09:57

Got a JBL SCS200.5 speaker system for free and was thinking of using it instead of the soundbar. I am going to use it as 3.1 configuration initially (sub, L R and centre). For the sub I found that I should set the crossover at 120Hz but not clear about the other speakers. Have configured them as "small" but their specs according to the manual are 110Hz for L and R and 100Hz for the centre speaker. Should I use these values for the crossover?

What receiver are you using?

Looking at those speakers the crossover would probably be set at 120Hz - 150Hz...

It's a Denon 1612

Don't go by specs because for low end htib it's useless. Go by driver size and cabinet size with approximation.

No real figure

Doesn't make sense as you can have speakers with same driver and cabinet size but difference specs. The materials used surely make a difference?

I'd it's one of those htib you may find the mai n unit has eq applied to the speakers and they usually have crazy low 4 ohm impedance

Isn't it 8 Ohm according to specs?

I thought that the geometry and the material of the of the cabinet make a difference.
The trade-off for the smaller size is a higher power requirement.

That's what I am saying. The enclosure's materials and design play an important role in the quality of the sound.

OK, Connect Subwoofer LFE to LFE on your receiver and run Audyssey MultEQ.

Have a look and report back what Audyssey sets your crossover's to.

120 for sub and 120 for central 130 for L/R

I'd set to 160hz.

Is that for the sub?

If it's for the front speakers what happens with freq between 120-160Hz if the sub crossover is at 120Hz

Manual says sub at 120Hz if the receiver offers the option

Thanks. Didn't expect that many settings tbh

About the -6dB at the Freq Response specs - is this something I need to adjust in any of the settings?

From the manual when using
DOLBY DIGITAL OR DTS (OR OTHER DIGITAL SURROUND MODE) CONNECTION

If your receiver allows you to set the crossover frequency between the subwoofer and the main speakers, select 120Hz or the setting that is the closest frequency below it.

Unfortunately can't place the sub close to the centre channel
