... but what do you actually have in your mixing room for bass traps?
A)- 6x6 and 3x4 wood bookshelves, both stuffed with Owens Corning, front covered with black burlap
B)- Real Traps Room Kit (eight standard 2' by 4' MiniTraps plus three MicroTraps)
We modded the bookshleves into bass traps ourselves; Real Traps were pre-made
... What size room are you using them in and how do they work in that room?
The room is 14x20x7. MiniTraps in each of the corners, other Real Traps are moved around the room as needed. All the Real Traps are on mic stands. For instance, I make a semi-circle around me when doing critical mix down. Kind of looks like Stonehenge
!
The Real Traps work great! I choked on the price at first, but then did the math if we built everything ourselves (hunting down all materials, buying materials, shipping, tools, time spent building traps, a space to build them, etc. etc.) I was in a real time crunch and just worked a ton of OT at my day job.
So I bit the bullet and ordered 11 Real Traps. The money would've gone to upgrading the mic collection. Turns out the mics we had were fine - it was the room that needed upgrading!
The Real Traps are worth every penny and then some. We are able to record 7 or 8 musicians at a time in the room live - and it sounds great. Then rearrange the traps the next day and mix in that same room. Pretty cool.
There are other companies out there - some cheaper - some more expensive. Ethan was an incredible resource -- both on this bbs and on the phone. He really "schooled me" on the nature of room acoustics and stuff. I'm glad I went with his products.
The next step is to replace the bookshelves' stuffing with rigid fiberglass and throw away the fluffy pink stuff.
Although I have a good amount of navy blue Guilford FR701 for that purpose
