Ah, I see, all bets are off I think if you're not using Room EQ. By Room EQ I just mean any program and mic combo that you use to measure your in-room frequency response at your listening positions - after which point parametric EQ is used to reduce peaks in the bass (& sometimes to boost troughs) which is created by the bass & room interaction. I use a UMIK-1 microphone and then use REW, some people use DIRAC and I think there's a couple of other software solutions out there. I mean you can enjoy your speakers without using Room EQ, but trying to compare your F35's that have more bass than your prior speakers when you're not using Room EQ is going to potentially make your F35's sound more bloated in the bass which could mask other areas. If I was you I'd stop obsessing re your comparisons of your new F35's with your prior speakers, and just be very happy you've got a great speaker in the F35 (& at a good price!) - and then instead work out how to optimise your room in terms of speaker & listening positions and also using Room EQ to get the most out of those very good new speakers you have. You can also learn how to do an Anechoic EQ on the F35 to optimise it further, alongside your Room EQ. I'd just start focussing on the F35 if I was you and forget about comparisons with your previous speaker.
EDIT: looking back at our previous conversations on here a while back I advised that I thought this speaker would be good without Room EQ due to the gradual roll off of bass, and I still think that's true, but you can optimise it further using Room EQ, and I didn't realise you were going to be comparing it to death against your prior speakers....and I think if you're going to be comparing them then you should use Room EQ and also control what you're doing a lot more than you currently are to make it an even comparison.....but I don't really advise you to go down the rabbit hole of formally & rigourously comparing speakers, it's a massive pain in the ass to do it properly & so many pitfalls.....instead just optimise those F35's if you want like I was saying in the previous paragraph.
EDIT#2: you might need to invest in a miniDSP EQ solution in order to apply EQ to your speakers if you're not using something like a PC or laptop to play your music. Have a look around on ASR to learn about RoomEQ & miniDSP, and then think about what your next approach is gonna be, if you are gonna do anything further.
EDIT#3: I spent a long time listening to my JBL 308p Mkii speakers with only an Anechoic EQ and no RoomEQ and I really did enjoy them like that. At the moment I'm using RoomEQ, but there's no law that you have to use RoomEQ....just if you're gonna rigourously compare your F35's to your prior speakers you need to control what you're doing in the comparisons a lot more.....but really don't do that, I really don't advise you to keep trying to compare to your previous speakers, too much to go wrong to give you false impressions and too much of a pain to do it properly. Start enjoying your speakers instead and also if you like then learn about how you can optimise them further.
