Yes, but it will certainly also be very frequency dependent. I doubt that muffs do much to block vibrations through the skull, it doesn't cover much of...

I've used Bose noise cancelling headphones for years, on commuter rail and airlines. Let's you easily listen to music/movies while travelling. Great for...

If you apply enough felt appropriately, you won't need to consider the off-axis while designing. Felt can smooth on- and off-axis well. Once you verify...

Since you do have felt, consider my suggestion to use it for design only. It will improve both the on-axis and off-axis. This will allow you to more easily...

Neoprene may be good for panel vibrations, but not for a baffle diffraction application. That name in the first article sounds familiar. It uses misinformation...

I doubt seriously that the neoprene will be a benefit. The sound waves needs to pass through the material and absorb some of it. It may also be that it...

Poor wording in my question, but yes, I was wondering if the grille is flush or not. Your test with the cardboard cutouts looks to be flush. A gap like...

That grill is positioned proud of the front baffle? There's a gap under it, that is?

I was as well, but was more surprised by the difference between WT and WTW. The "hole" in the power response below Fc is also very prominent,...

IIRC, D'Appolito moved to LR4 primarily due to the additional protection for the tweeter. But certainly more mids or woofers are then appropriate since...

I do agree with this. D'Appolito is MTM (WTW) with BW3 or LR4 and with driver separation within specific wavelength requirements for the desired Fc. First...

Here's one more graph. This is a comparison of the power response of the three systems, but with driver directionality turned off. It becomes a function...

The first and probably the most important graph is the power response overlay.
The tweeter rolloff is rather exaggerated. WinPCD uses...

I'm going to post a number of window captures of three different system models from WinPCD. They are:- 2Way MTM BW3 2000 WTW Inline - Adjusted Fc

I'm modeling some in WinPCD now. Will include horizontal and vertical surface plots and calculated power response.
