Needs some break-in time, and there is zero information in the package on wall cavity prep. I think it is fairly important to brace the drywall to prevent it from vibrating/ rattling. Also to fill the cavity w. fiberglass insulation. It is easier to do this up front, rather than taking the speaker out of the wall and retrofit after you find that the wall resonates like crazy.

Great speaker

I replaced the Aria in wall speaker with the Alpha just like another reviewer did. I built a box around the Alpha and the sound really improved as compared to the Aria. Building the box in the wall made a big difference as I hadn't done this with the Aria. I then purchased a subwoofer amplifier and this helped the sound too. However, building the in wall box around the subwoofer was the thing that made the biggest difference. Now I'm rocking out in my bathroom with my system!

Speaker quality seems good but grill doesn't sit tight enough on speaker and creates some vibration. Recommend a better attachment system for the grill to the speaker body. Also, grill is not easy to paint, I had to pull out the mesh screen and spend a lot of time painting/touchup/perforating. Recommend larger holes in grill to make painting easier.

Great solution for home theatre low end subwoofer if the baffle is dampened properly. Nice stealth look.

Well-made, clean install, Would benefit from a back-box install to control x-max. Not truly a sub-woofer in that low frequency is 33Hz, and seems like it would benefit from a filter that cuts lower frequencies.

It is awesome, the performance is amazing.

I bought these to replace the 3 Aria 10" Subwoofers I previously had installed in the ceiling of my new home. These weren't available last year, or I would have put these in from the get-go.

The Aria still did a pretty good job, but they would occassional distort if they got a really low frequency signal at high volumes.

I've installed one of these new Alpha Subwoofers so far, and there is definitely a difference in low frequency handling. I was also able to give these more of the lower frequency band, as well. I had the Aria's crossed over as low as possible to prevent them from having too much to deal with - about 40Hz. The Alpha is crossed over at around 60-70Hz, which does a better job filling in the lows my Amber 6.5" 3-Ways can't reach well as well.

People should be aware that these speakers require an 11" hole, whereas the Aria's only needed 10.5" holes - so these are not a direct drop-in replacement for the Aria's. I had to cut another 1.4" all the way around to get these retrofitted, which was more fun that I wanted - but not terrible. It's just a lot of work cutting upwards into the ceiling, on a ladder, especially since I'd backed the speakers with a box, so I had to cut that, too - not just drywall. Still, the results are worth it, I think. :).
