Ceiling Bass Traps
There is no question 705 works well for bass trapping in general, though other materials are generally more cost-effective. For instance, 703 performs similarly and is often about half the cost of 705. In some regions, rockwool is significantly cheaper and performs reasonably well. The main... -

Ceiling Bass Traps
Test tones can be useful (ie, individual frequencies), but sometimes nulls and peaks can be very close together. For instance, you could have a +12dB peak at, say, 58Hz, and a -12dB null at, say, 62Hz. If you have a 60Hz test tone, it will be somewhat difficult to hear what's going on. This is... -

Ceiling Bass Traps
Looks to me like nulls centered at 45Hz, 75Hz, 175Hz, and 300Hz, with a peak at 95Hz. However I wouldn't worry too much about attacking each individual problematic frequency; all of these will be improved as you add bass traps (the entire frequency response of the room is flattened as you add... -

Ceiling Bass Traps
The test tone that you can download there is pink noise, filtered at 400Hz (ie, everything above 400Hz is filtered out). This allows you to hear the low end buildup more clearly. You can certainly use pink noise, but the high frequencies tend to dominate what you hear, the test tone above sounds... -

Absorbtion over screen?
In general, I don't think there is much need for high frequency absorption on the front wall (or screen) of a listening room, particularly if the rear wall is well-treated (absorption and/or diffusion, and bass trapping). High frequencies are pretty directional in nature, and the tweeters are... -

Panels are Done....for now.
Nice job on the panels, particularly the lighting! We've had customers do that before, it works beautifully! Ethan actually did this in his living room (look at the side RFZ Panels at first-reflection points, and the front Corner MondoTraps and TriCorners): I love seeing/reading about the... -

Ceiling Bass Traps
With bass trapping in general, there are 2 main parameters to consider: first, is the effectiveness of each individual trap; second, is total coverage area in the room. The more high-quality traps you get into the room, the better the overall sound will be. This is of course an...
