12'x16'x8' room OK for good stand mounts?

JBL 4309! Your welcome!☺️

I have a similar sized room with a pair of floorstanders, a pair of small subs in it and it works fantastic. Getting the room treated will be critical and I worked with GIK. I was able to send them some measurements from REW and they set everything up. 

Don't rule out trying ProAc D2 or D2R on very sturdy stands.  They are very warm and natural sounding, especially with string and reed instruments, and might be a little bit more flexible in the distance from the front wall.

I used stand mounts in a room of similar size. Placed speakers along short wall, audio rack to side of listening chair. Made my own absorption panels. Nothing in room but my chair and selves for music. 

Speakers were toed in about 2' from side walls and 3' from front wall.

Love to own a pair of Pulsars.

A floorstander speaker will definitely work in your room if you can get the room dialed in. I use a corner set up as suggested above. I highly recommend a consultation with Jeff at hdacoustics. He is very good with smaller rooms. 
good luck !

unfortunately the Joseph audio aren't as good as the new gold that MPD Tweeter is way better than any dome tweeter on the market the three-dimensionality is huge The sounds they just envelops the whole room as good as a Joseph are their driver technology hasn't changed in 30 years and they're nowhere near as three dimensional as the monitor audio gold and platinum.

the monitor audio gold 200 and 300 sound amazing and your room is not too small my room is only eight and a half by 23 and I have the platinum 200 ll and they sound incredible.

actually you won't need room treatments if you treat the vibration coming from your speakers with Townshend podiums, they're not cheap but they totally eliminate the problems in the room that speaker vibration cause, room problems just disappear, look them up, best upgrade I've ever done, it sounded like I had upgraded all my electronics, it also gets rid of the constant Earth vibration that's in the Earth all the time, the improvement is mind-blowing. they isolate down to three Hertz.

That room size is perfect for the Prism or the Pulsar2’s. Depending on your musical tastes, you always add a sub or two later.

All the best.

If the JA Audio speakers do it for you, as they do me, you can get them to work. Do as Jeff Joseph did in a small NYC room and position the Pulsars or Prisms so they’re in the corner and the corner is at the highest depth of the speakers and pull them out as far as you can until the sound just gels. This way you maximize the space/benefit of the room but definitely look at GIK for room treatments to further benefit the sound. If it worked for Jeff Joseph I’m sure it can work for you too. 

I think you have a lot of room to choose your speakers. Your room is big enough for a 6 - 7’ triangle.. so three feet behind the speakers and three feet on either side of the speakers. And to have 4 - 5’ feet behind. If you add dampening to the front and rear walls, then at sidewall reflections you can use towers.

I prefer towers to stand mount myself. I like the coherency. I have heard and really like Joseph Audio speakers. But I am a Sonus Faber fan for me.

A few years before I retired, I did the same thing you are doing. Got my system thinking I would not want to upgrade after, but I could tweak. I think it was a great plan. I went from 45 minutes a day, to 3 + hours and it is my most enjoyable hours each day. I can’t begin to tell you how much joy my system brings to me.

FYI. For me I had bought a pair of Sonus Faber Olympica 3 for my retirement speakers (I’m not trying to convince you… these were perfect for my tastes). Anyway after a couple years of retirement I realized I could upgrade again. I over doubled my investment to what I have now. The difference was amazing and also led to the three + hours a day I spend here.

So, I think you are doing the right thing, at the right time, in the right sequence. My recommendation: don’t compromise if you can avoid it. You should have the time to enjoy it and, well, life is short… and getting shorter.

Thanks. 

Joseph Audio in a heartbeat. Your room is about right for bookshelf speakers. However, if you go with JA, make sure you have at least 3 feet clearance from the wall behind the speakers. If you can, the JAs will give you a deep and wide soundstage and above average bass (for bookshelves). You can always add one or two subs down the line. 
 

if you can, my advise is to go for the Pulsars. Can’t go wrong with these. 

You room size is very good for stand mounts. Yes, room treatments will considerably enhance your listening experience.

Based on "audio show" listening experiences, I would take Joseph Audio over Monitor.

Whats your budget and amp?
