Mixing in my untreated bedroom....what to expect?

no stress... if you know what you're doingand get sued to your room modes after a few mixes that don't translate you'll figure your space out... the HS7s might be just the ticket. I find the 5" woofers to be grossly inaccurate with hyped lower mids, but 6+ is usually okay. Small is good if your room is a tight space, but the 5s just don't work,e ven with a sub. Also, monitor quietly so you're not exciting the room modes so much. That's a good practice anyway to minimize fatigue and reduce distortion from the amplification that makes stuff sound different and often better. Good rule of thumb is that if you can't hld a covneration over your playback volume without straining to ehar and raising your voice then you're too loud for extended lsitening. emember that amplifier distortion specs are emasured at 1 watt power at about a metter's distance. You'll be more like 2 feet or 2/3rds meters probably so if you monitor a little louder you will be eharing more than the rated distortion with les air absorption of the high frequency harmonics generated by that distortion. In a small untreated room I stay away from sub woofers and look at a spectrograph if I feel uncomfortable about my low-low-end. You'll get a sense of when your master bus looks hotter than what you're hearing ebcause inaudible deep abss is driving it ahrd and you'll throw the spectrograph (or fab fitler or whatever) up and look at it. This is the only time I advocate 'looking' at the music while mixing, when its inaudible through your playback setup.

I don't know about sonarworks, but I have experience with JBL's genelecs that do the impulse response and tune for room modes and the JBL software worked EXCEPTIONALLY well. When they were new I worked with a guy who ahd them and we even sued them in well treated commercial studios and tuned up and got ebtter fidelity (to our ears) than using the studio's near fields (although i would always keep going back to the NS-10s, but I'm like that). So if you have trouble, sonarworks is a thought, however the JBL software also knows those genelec speakers aso its super precise once it scans your room. I am not sure if a 3rd party software designed to work with ANY set of monitors will be as good as soemthing designed for a specific playback system and it COULD cause as many problems as it solves. Sometimes you just need to decide what you need to hear and get used to the rest. Train your ears to hear it right. One thing I do in my untreated rec room is position my kid's toy shelves behind my mix position and they act as diffusers, book shelves are actually used in lots of commercial studios based in converted houses with bare minimum treatment so you will want to put those bookshelves you mentioned behind the mix position or, if its a good spot, position your work area in front of where the book shelves already are ;-) Maybe position yourself slightly off-axis too so the walls aren't parallel to your speakers. Make sure that when you do decide to lsiten loud for a minute or two that its not making anything rattle, like a bed frame, that'll make it impossible to get a feel for how your mix is loud.

By the way, i have sworn by Yamaha and Tannoy as my main monitors for over 20 years. The powered yamahas are great, though i slightly prefer the older, non-ported passives due to familiarity. I flirted with JBL Genelecs (as mentioned) and I still own a pair of Events from when they were the hot shit and I still check on them sometimes, but Yamaha is where its at for low level monitoring and getting the mids and dynamics just right. You are making a good choice with the HS7s.

I hope that helps. I friended you on soundcloud, but I don't want to tlak about your music until I get a chance to lsiten on some of my monitors. I'll check out your mix later if you want, but regardless of how you're doing, the HS7s will probably be an improvement in any spaceif you don't currently mix on quality speakers.

I wouldn't use cans for lows, there's no air space for the waves to develop... and your bass is split whacking into both ears and there's no real 'center'. I am really anti headphones for mixing. Others disagree. I still know in my ehart they are rpetty well wrong in their thinking, but if theya re happy with their mixes that way, great. There are no rules, but the guidelines are absed on good science coupled with the experience of lots of talented people spanning the hsitory of recorded music. When headphone-mixers are not happy with their work but stilla advocate cans versus speakers I can tell the cans are the problem and they just don't want to admit it. Many people will hear your music one arbuds, but a speaker mix translates well to ear buds while a headphone mix is maybe not going to be so hot on speakers. We're not raised hearing msuical sound right enxt to our ears. We are used to it coming out of speakers when we're little, even if those are TV speakers...

Genelecs ARE JBLs

your bed cover will only absorb high frequency energy and not much more... you don't really want to absorb anyhting but bass though, that'll sound as weird as having reflections that cancel the direct sound... you want to DIFFUSE. You trap bass and diffuse mids and highs... not important... just don't waste your time with you bedcover unless you need to cover a window directly behind you and lack thick curtains. Glass needs more help with high frequencies than dry wall.

I haven't tried the SubPac & was super skeptical but I've been hearing that it's working really well for people who work in situations like yours. Friend of mine swears by it & sent me some before & after mixes & they showed a marked improvement.

Just another option I figured I'd throw out there.

No matter what you do go with so long as you learn your mixing enviornment you'll be good- way better off than people with all the coin to get something fancy but don't bother to learn it properly.

just did soem lsitening, ic an't speak to the ambient piece, I think the piano is muffled and weak, but maybe you wanted it to belnd into the otehr sounds, its ambient music... the otehr one that you said was a pop song? Its hard to say... there's not much more sound in it than the ambient piece. I wouldn't have mixed it that way but nothing jumps out and hurts my ears either. If you gave me the pop song to mix professionally I woulda probably made the drums towards the end pop more and less muffled buts till in the background... the vocal is brutally overcompressed, but people do that and I guess the pp song is remix? You probably got the vocal all rushed to death like that. I think the piano sounds over-EQed, but tis probably a plugin, right? maybe it came that way and you left it flat? If that's the sound you were working with and you liked it then its fine. You don't really have enough music for me to give any advice. Ic an't tell what you're about.
