Appreciate shadorne your input, the cabinet is built-in and it looks like it’s heavily braced. Actually I have my sub(golden ear force field 3) behind the tv and it sounds acoustically good. I’m just not getting the sound I wanted on my in-ceiling speakers (B&W ccm663) that’s why I decided to put front speakers and just use the in-ceiling speakers for atmos setup.

You need to soffit mount. This requires a flat front surface and a method to flush mount the baffle of your speaker so that it is seamless. If you don’t flush mount and your cabinetry has holes then you will get plenty of edge diffraction. Also the cabinet need to be inert and heavily braced or yo will get unwanted vibrations. Finally - this setup will boost your bass by 3dB from about 200Hz down - so you may need to adjust for that. Here is an example https://dt7v1i9vyp3mf.cloudfront.net/styles/news_large/s3/imagelibrary/q/qa_0116_03.jpg?4CMSefIKMUlI... It is ideal for bass response (no quarter wave cancellation at all) but it is tricky to do correctly as any coupling of the speaker and the wall can give unwanted vibration...and because the bass is so precise you will excite room modes . |
When you place speakers inside an entertainment center, you are essentially placing a box inside a box. The speakers will sound ok, but never more than ok. The speakers most likely will sound recessed, veiled, and closed in. Any audiophile yardsticks like separation go out the window. I never heard of anyone suggesting to do this with floorstanders. I did it for years with monitor speakers and I compromised the sound greatly. The speakers actually sounded better on top of the bookcase, rather than inside the bookcase. I understand that there may be room issues that prevent standmounts or floorstanders being out in the room. You may be better off keeping the speakers alongside the entertainmnet center and then moving them out into the room when you want to listen. Rich |
