Joseph Audio Pulsar placement and tips


Dear Pulsar users,

I'm trying to find the optimal position and I would appreciate your feedback.
How big is your listening space, how wide are the speakers apart, and how far from the listening position, also what's the amount of toe-in? I am struggling to find the ideal soundstage width. I have a small room, 10x13 feet, speakers are on the long wall.
And if you don't mind, what amp do you use, what speaker cables and are you bi-wiring?
I'm using a PrimaLuna EVO400i with NOS EL34 tubes and Van Den Hul Hybrid cables, but there are some bass notes which are not very clear, nice, for example in Tiger from Paula Cole.
cheers,
Arthur

I own Joseph Audio speakers but room situation is much different than yours. I'm in a 16x23 room, so speakers are about 8ft apart, I'm about the same distance to each speaker, and they are toe'ed out almost straight forward.

For your room size and long wall placement, I recommend looking up "Master Set" speaker setup methodology. You probably will need to sit more near field, as well as toe in more to minimize reflected sound unless you have robust room treatment.

Thanks, that's the method I used, but first they were quite close together and everything sounded cramped, now they are wider, but I can clearly hear the different instruments coming from the sides, though also between the speakers. Maybe the truth is somewhere between. I have GIK bass traps panels behind the speakers, diffusion in the middle and behind the seating, and also 3 bass traps on the ceiling.
If you're gonna toe them in, then it should be very slight per Joseph Audio.
So sad to see you got roped into that Master Set BS. What a load of baloney! Speaker setup is so simple. Leave it to this clown to make it IMPOSSIBLE! lol!   

There are two separate yet related aspects to speaker setup. First is to find the location that gives you the best balance of bass response. This means moving them closer to or further away from the walls in order to find the smoothest/deepest response in your situation. This involves zero listening for imaging, it is all about smooth response. 

Next is what you want, imaging. Use a tape measure to ensure the speakers are precisely equidistant from, and symmetrical to, your listening spot. This all by itself will give great imaging.  

Finally, adjust toe in to achieve the desired balance between image focus and sound stage width and depth. Pointed directly at your ears image focus will be max, super solid, and deep, but not very wide. The less toe in the more the stage will widen, but there will be a tradeoff with depth and focus. 

It really is that simple. Do not get distracted by BS claims of imaging all over the room. Physically impossible. The best that can be said of this baloney is the imaging can be equal all over the room- equally bad!  

By the way, none of the stuff you are talking about matters. Someone tells you how many feet apart their speakers are, that means nothing in your situation. Your amp, cables, music- irrelevant. All that matters is your location relative to your speakers. When that is equidistant and symmetrical you will have the best imaging you can get with your setup. Period.
Thanks @rlb61 I'm now experimenting with different toe-in angles.


@millercarbon, thanks for your thoughts: I started with a measuring tape and a laser, got everything perfectly symmetrical but the imaging was off. I thought I have channel imbalance issues, tried to measure the amp, sources, etc. That's when I stumbled upon the "master set". It made sense to me since no room is equal, nor perfect, and the reflections will not be equal either. On the left, I have big windows covered by heavy curtains, on the right I have a door. There is a desk in a corner and a shelf in another, so it's quite difficult to get symmetry. Now it sounds quite good, but I wanted to get specific input from other Pulsar owners to dial in the last millimeters :)

The reason I'm interested in the experience of Pulsar owners with specific songs is to figure out if the low bass issues are speaker-related or something else, like amp, room, cables. A few songs that have these notes: Bird on a wire, the big drums on the left have a long reverb that lingers and causes constant vibrations that I feel in my chest and feet. In Paula Cole's Tiger, it's quite similar, the bass comes in around 45 seconds in the song and sounds a bit muffled/muddy to me, but I haven't heard it on another system so I can't compare. Another slightly annoying sound is in Paint it Black by the Rolling Stones, comes from the center, really low and really not nice, sounds more like someone hitting a wall. But maybe this is just in the recordings/mastering.
By the way, the Ballad of the runaway horse sounds perfect all the way, even with high volumes.
So if anyone is in the mood to listen to these songs and give their subjective feedback might help me get on the right track :)
