I just got 4 of the MSR spring traps in my room today. I replaced the 4 primacoustics corner traps on the frontwall with the MSR spring traps. What Kal is saying is very important. Most basstraps tend to be more broad range control. The springtraps are only effective in the bass. The result was even tighter more articulate bass than before with the primacoustics and the added benefit of much more lively and natural sounding mid-range. I am too tired to post XTZ room analyzer measurements now. I can post them later. I got lucky on Audiogon and got them pretty cheap from a great guy that packed them well onto a pallet. Also, another member of this thread, Bill, was over tonite. Maybe Bill could chime in on what improvements he heard as well. Thumbs up for MSR!
Good Morning Michael. Thanks for an evening of listening to some great sounding music! (the food was great too!)
In light of waiting on what the measurements show, I do believe the MSR's displayed a different performance from the primacoustics. From what I was hearing, both traps seem to work well in the bass region. But the mid and upper frequencies appeared less dampened with MSR traps (which I believe they are designed to do). At one point, during a bass-heavy song, I reached behind one of the MSR's grill cover, and could easily feel the panel vibrating sympathetically with the bass. So no doubt the panels were reacting to the low frequencies. Overall, I think the addition of the MSR's were a step in the right direction. Now, I will have to see how the RealTraps perform in my room once I receive them. Of course one thing I'm looking for at this point, is better bass control between 100 and 200hz. Which, I believe the RealTraps will address.
