@rwbadley absolutely agree... I have volume set to 10.5. Perlisten did reach out and want me to software down-date to 1.23, but it’s looking to me like a bad amp module in one subwoofer.
@kennyc so now having many subs, both JL and Perlisten and sadly both my JL and Perlisten now have gone bad on me (one sub in each pair)... My thoughts thus far.
Build quality JL
Woofer quality Perlisten
Bass presence and SPL force JL
Bass speed and articulation Perlisten
Features and functions Tie
Customer Service Perlisten
Reliability JL (from my own personal experience)
So essentially a tie, however I would venture to make the case that for me I’d go JL F-12 if I could do it all over again at this juncture. Maybe I’ll change my mind given more time and once both D12's are subs are up and working. But I'm happy to have yet another sub sound in my collection (future speaker pairing and such).
Overall I’m still of the opinion that these are very different subwoofers.
I would liken SVS to JL, and Perlisten more so to REL. Again not that any of these are the same but in a sense of which sound is closer to which.
