Sure. Do point them toward the listeners though if you mount them up high.
No, there is none:I presume there are no mounting points on these speakers? Going to be challenging mounting them to the ceiling & I guess its a big no no turning them on their side?
For Stage A130 owners with unlimited DSP such as Roon/Foobar/Jriver players here is 20 times PEQ filter string based on Amir's anechoic analyze that will smooth out most patterns, EQ policy is based on DI curve (directivity index) so not in favor of close nearfield super flat on axis but optimal at farfield 2 meter and up as for spinorama standard (CEA/CTA-2034 ANSI)..

There's no samplerate involved for smoothing process using 20 times PEQ filters bank samplerate comes in only if you set that filter bank as a convolution filter.
Studio line is the previous model, replaced with the Stage. You can google the models for speaker size and freq. response and might find reviews, too. When the Stage A 130 go on sale, it is $179/pr. The Studios and the Stage A 120, will be okay. JBL quality is great with over all reputation for years. Whatever your budget will afford. Polk S 20 and S 15 are good too. I have the Polk S 15 as my side surrounds.
My choice is the Stage 130. You can look up the specs for both and decide. Plus any reviews.
I would think it depends on your intended listening level and distance, and crossover frequency to your subs. The A130 is unusual in the 5" class for its low distortion at lower frequencies. The A120's distortion is likely to be much higher below 200 Hz or so. Look at the ASR reviews for the Philharmonic Affordable Accuracy Monitor and the Dayton C-Note for examples in the 4" woofer class and compare to the A130 review. If you listen relatively close to the speakers and at low levels, this will not be an issue for you.
