Ultimate High Performance Audiophile Loudspeakers
Premium, luxury, preeminent, supreme, unparalleled, paramount, primo, leading, first-class, finest, precious, life-like, extravagant, etc.
Get ready because you’re looking at the most performance you can get out of an inwall design before paying exotic prices. This line delivers luxury fulfillment of life-like audio reproduction. Envision a home theater capable of immersing you into the true embodiment of the movie director’s dream.
Features:
- Exceptional low end fidelity for the most intense musical or theatrical pieces created by Provlar™ woofers. Our improved version of Kevlar, introduced in 2010.
- Vivid high end and unassuming midrange performance for greater accuracy and more life-like imaging, taming the shrillish properties of typical Titanium with Zelenium-Dome™tweeters. Our improved version of Titanium, also introduced in 2010.
- Easy one-cut, drop-in installation puts built-in audio within reach, with Exact Fit templates and a precision flange that clamps the speaker securely to the drywall.
- Get a lifetime of reliable sound from the durable, CAD (computer aided design) modeled, injection-molded butyl rubber surrounds suppress unwanted cone resonances.
- Enjoy greater accuracy and more realistic imaging with aiming tweeters that pivot independently.
- Timbre matching (the family of speakers sound the same) ensuring utterly seamless blending from speaker to speaker. They are acoustically inert, for dynamic, unimpeded sound and more uniform coverage, even in larger rooms with nearly transparent, ultra-small perfs
- Practically invisible once installed with the magnetically attached exclusive wafer-thin Rarefied-Grille™
- Visualize an even more hidden look by painting the grill and frame of the speakers for a nearly invisible installation.
“Finally, our
flagship line of speakers are here! This HD line of speakers are very
good….and very good for the price. We should sell these for more, but
we can’t in good conscience. Factory direct from a strong retailer is
your best bet these days…no middle-man”

I finally got my new system up and running and am nothing but impressed and happy with these speakers. I paired em up with a SVS pro 2000PB and the Marantz NR1510. Room size is 18×35. Right on Inwall.com . The Pearls deliver! More than enough to fill the room like a concert without pissing off the neighbors.
I am a DIY’er and had pre-wired a 5 speaker system in
new home. These speakers went in easy and after upgrading my receiver these things sound really awesome! There are times while listening to music that it sounds like I have a subwoofer connected but I do not. I highly recommend these as you will save yourself a lot of money. Thank you!
This is the second order I have placed for the second of my own house installations. These speakers are fantastic! Can’t recommend them more highly for anyone looking for an in wall / ceiling solution for their house. They rock the place!
thank you in-wallstore you are the best!
I came across this company and pondered buying for over a year. I finally bit the bullet and have been extremely satisfied. I’ve been using these for the past 18 months and couldn’t be happier. Since my house was pre-wired for ceiling mounts I really doubted the sound would be as good as my old free standing speakers. Again, these speakers are great. You can’t even tell the sound is coming from above. Also, if you have questions, their customer service gets back to you very quickly. I wouldn’t hesitate to buy these again.
