Just got my 4 tri bass traps today. Did a quick placement and audio testing of tracks I know well. I don't know what I'm doing wrong, but the bass traps sucked all the bass out of the room. Bass sounds muffled and undervolumed. It's like the bass trap, uhhm, "trapped" my bass. I Will need to do more tests. My issues could be that I sit in a rather open area, about 5 meters behind me is open.
The product itself looks well made,though I do have some dents in the corners, maybe due to shipping problems. But still an impressive looking product.
UPDATE: as mentioned below, after increasing the volume on the two subwoofers which are inside each goldenear triton two, the sound was really great. I think the bass traps simply leveled out a ton of peaks and valleys and therefore the original volume level didn't cut it anymore. Raising the volume a bit (around 11 oclock of you own this speaker) made a huge difference. I"m getting a measurement mic next week to do some scientific testing, but until then I'm really liking it. I think I'll get some art panels and 242 panels next.
