Greetings, everyone. This is my first forum post here, but I've been lurking/creeping about for a while.
I've also wondered whether or not the change in model numbers for the JBL Stage A130 speakers was indeed inconsequential, which I have a hard time believing because bothering to release a product with a different model number generally indicates that some kind of change took place, even if it's a small one. That sort of thinking, as well as Crutchfield having separate listings for each model number, brought something to my attention that might explain it & finally justify just why in the Hell there are so many Spec Sheet & User Manual PDFs out there & why I seem end up with a bunch of them on my drive.
I noticed two differences in the specifications between models Frequency Response & the perhaps more impactful Crossover Frequencies. Where the "older" model Stage A130 has the Frequency Response listed as 50Hz - 40kHz & the Crossover Frequency at 2.1kHz, the "newer" version lists the FR as 55Hz - 40kHz with the Crossover Frequency set at 3.2kHz. I took this information from the Spec Sheets published by Harmon & the Specs page of the separate listings on Crutchfield.
I'd like to point out here that the publication years were 2017 & 2018, respectively indicated as "older" & "newer" above.
I don't know if that would account for the differences or not, but hadn't seen it mentioned yet. Forgive me if someone did mention it in the last few pages of this forum. I didn't get through all of them yet.
The pair of JBL Stage A130 speakers I ordered from Crutchfield are the "newer" model with the increased Frequency Response (which I confirmed by playing a frequency sweep) & the higher crossover point. I really enjoy these speakers & listen to them almost daily mostly at my desk to listen to music. The speakers are naked (grills off), toed in & decoupled from my desk using thick isolation pads for studio monitors & they sit at a distance of 3' 2" from my primary listening position. I use the Aiyima A07 amp & 16 Oxygen Free Copper speaker wire to connect them to my desktop. No DAC yet because so far I'm doing okay with my Gigabyte Z390 Aorus Pro motheroard's onboard sound which is an electronically isolated Realtek ALC1220-VB High Definition Codec.
