Should I upgrade my Monitors or get a sub?
Hi, I desperately need help with deciding on what to do about my monitoring.
My current setup:
I have a pair of Adam Audio T7Vs on stands on my desk, ear height is ~127cm. My room is 4.07x3.38m and 2.55m high. My monitors are centered along one of the long walls and 107cm apart. I can't change their position because I share the room with my partner as a creative space and they don't want to rearrange things (which is totally fine by me). As of now I only have minimal treatment, but that is subject to change soon as I recently analyzed room modes and will specifically treat the worst offenders (134Hz to be exact). RT60 is <0.5s according to REW. I also use SoundID Reference to smooth out the rest. My main use case is Mixing/Mastering of dense Metal mixes with the occasional Pop or Electronic project thrown in between.
My current issue is a lack of bass and low mid - mid detail. I really like the U-ART tweeters, even though they can get fatiguing in long sessions. My hypothesis is that the low tuned port of the T7V makes bass sluggish and that the woofer struggles to represent ~45-2600Hz all at once. I need a detailed midrange in order to properly mix dense drums with distorted guitars and intense vocals all at once, but good bass would probably help when mastering.
My options: Either I keep the T7V and get a sub or I sell them and invest the whole budget in better monitors. (selling would get me ~300€)
Adam T10S 350€ refurbished - Reduces load on the T7Vs woofer and thus may clean up mids, but could be too much for my room
Adam A7V 800€ used - Straight upgrade with SoundID integration, probably slightly better bass but way better mids and high end
Focal Alpha 65/80/Twin Evo 500/600/750€ used - I would really like to hear your opinion on these, they're said to have a lot more bass and overall headroom. The Twin really excites me (probably because it looks cool) and 2.5 way might help with the midrange? Also no dip in the mids like all Adams.
Dynaudio LYD-7 500€ used - These seem to be similar to the T7V with a little more detail, don't really excite me
Kali Audio IN-8 2nd Wave 740€ new - apparently a popular choice, but limited bass headroom due to artificial DSP boost
Any help/advice would be appreciated, also feel free to suggest other monitors (same price range in central europe).
Edit: I may have understated my room treatment and experience level haha...
Minimal treatment was the wrong choice of words, my floor is covered in a thick carpet, I hang thick curtains infront of the windows when I'm mixing, I have bookshelves acting as diffusors and diy rockwool broadband absorbers in some places. I just don't have deep wedges on every wall like professional mastering studios and my ceiling is completely untreated. I also know how to use and interpret REW (I'm an Electrical Engineering student lol) and I use SoundID Reference for room correction after purposefully placing furniture and absorbers using REW. Sorry for confusing you guys and thanks for the replies!
