what do you think of this setup of a polk audio m70 speaker. I can feel the keys vibrate when I play lol. Any pros or cons about sound? I know they are somewhat directional speakers so ideally you want them to face you. But I like the fact that the sound shoots up and around the room as its reflecting off the back wall and side wall in a corner.

I'm having a hard time getting galaxy pianos sounding to my liking though. (Too much bass instead of clarity) its playing through my receiver at 24bit 192khz though so that's a good setting right? Let me know and try to keep it somewhat non technical as I dont have a sound engineering degree lol

That's obvious that you have too much bass when listening on that beats... Get some normal speakers, not something with four 6,5 woofers...

Why you will not buy some monitors and płace them correctly with the art?
And you have in the worst possible positive...

It cannot sounds well just looking in it.

The boomy sound is probably mostly to do with speaker placement. I'm not familiar with this speaker but they have a reputation for ample bass - maybe too much for natural sounding piano because a real piano does not have a strong bass component, comparatively speaking.

The speakers should be forward facing, away from the wall, forming an equilateral triangle with your position. Keep them well clear of corners or confined areas of any sort which will tend to resonate at low frequencies and emphasize certain frequencies in a way you don't want for natural sounding reproduction.

You can probably use in-computer EQ too, to shape the sound as you want - but after getting the speakers positioned well, preferably.

I would think if you kept your eq flat on your receiver you shouldn't have too much bass regardless of the speakers used as long as your speaker(s) is/are full range. I think I understand what you are trying to do with the tower speaker placed horizontal behind the KB - to use it as a widely dispersed sound source - but it might be some of the problem. Some smaller (4 perhaps for even dispersal) forward facing bookshelf speakers behind the KB or below might be worth trying. You could then add a sub to handle the lower frequencies, perhaps placed below and centre of the KB. Subs are omni directional so you shouldn't be able to tell where it sits relative to the other speakers. I think you'll have to do some experimenting with placement. Room acoustics influence the sound as well. As for the 24/192 source that should be an excellent quality setting.

thanks for the help guys. Yes the receiver is set to 'straight' no eq or dsp effect. they are also set to full dynamic range via receiver. You can see a piece of my second m70 on the bottom left of picture facing me at a 45 deg angle. What im really trying to do is emulate (in a ghetto way lol) the way a digital grand speakers face and also get the vibration feedback on the keys at the same time the way a real grands keys vibrate.

I really dont want to spend more money on more speakers as I got these two nice ones to fill the room with sound rather than direct sound that monitors do.

Im sure if I play around with galaxy pianos numerous sound settings I can get it to work right. ( I just dont know exactly how they all work together to create the sound I want)

I would have the speakers underneath the keyboard,facing the player. Towards the wall boosts bass unnaturally.

thanks larry I was actually thinking about this myself. Only problem is this is really going to raise the piano. I might just try it though. BTW speaker is not facing a wall. Its pointing to the ceiling.

on a side note.. that px3 in the picture with missing screws is going to turn into a vpc1 tuesday...cant wait!

One problem:

. . . Tweeters tend to be directive.

So if your tweeters are pointed up, and your head is beside the speaker, you're getting "direct-wave" bass (at full volume), and "reflected-wave" highs.

If the sound is somewhat dull, that could be the cause.

Tilt that upper loudspeaker, on its long edge, so that it's facing your head (as a monitor would), and position it so that its tweeter (wherever it is) is in the center of the keyboard. That will turn it into a "monitor speaker", more or less, and may help you out.

Try placing the speakers on either side of the piano, angled inward toward, and raised up on stands so that the top of each speaker is at ear level.

thanks everyone for your help. I will try it all the ways everyone said and let you know what works for me. Btw I am able to improve the sound with galaxy pianos by turning off concert hall effect(big diff in bass) and dynamic range of piano and low keys tone menu. anybody familiar with galaxy and yes I watched the youtube videos.

placing the speakers standing upright behind the piano works the best for me.( I took off the floor cones on the bottom of the speakers so they would stand flat on the desk) Laying the speaker on its side and putting the piano on top was great for the vibration through the keys but the sound still was muffled.(im satisfied with current setup producing the vibrations) someone needs to invent a speaker that is omnidirectional and sounds good.

Omnidirectional? Sure, they exist, here's one company (and I'm sure there are others): http://www.duevel.com/home/loudspeaker.shtml

Not cheap, although considering the high-end speaker market they don't seem out of line.

If you have your keyboard on a table, I'd give one of these a try:



I haven't tested one personally, but as far as I can see, it's a similar idea to the "transducer" in the CA95.

Search for "vibration speaker" on Amazon. They are cheap - 25 for a 10W model or 54 for 26W (CA95's is 15W).

No, it's 45W.

Why does it have "15W" printed on it then?
