  • 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.

Whole house set up! Review by Robert Center
I purchased these speakers along with the angled 1A ones for a 7.1 system...( have not hooked it up yet) these speakers for my whole house system are awesome! I placed ten ceiling speakers in five rooms of a home I just recently built and I am very satisfied with this product. Yes, it was scary purchasing such a large order and becoming concern with the quality and customer service . InWall was very accommodating and the quality is there... I hear it everyday.

InwallTech HD-650.1C High Definition Ceiling Speak Review by Mr. Pickey
WOW! (Posted on 4/3/14)
Superb speakers at an affordable price! Review by C. Connell
I have bought several pairs of "in-wall" speakers over the years. I have spent 2-3 times as much money on speakers that were of a lower quality and didn't look nearly as nice in the wall. I am very happy that i stumbled upon your website and will consider you first for such items in the future. Thank you! (Posted on 1/16/14)
My Speakers Review by Jonathan Fosbre
Love theses speakers (Posted on 10/9/13)
All around TERRIFIC purchase Review by Alan
I found the IN WALL STORE on the net, called in for some advice and within a week went with their recommendations. Brian, was wonderful...he answered every question (even the dumb ones) with the highest level of professionalism, and helped me find the setup that was perfect for me. I ended up spending about 40% less than I expected for a kevlar high end setup and it shipped quickly and was recieved in a very short time. All came packed safely and intact.

Installation was pretty easy, the hardest part was running all the wire. I had some install questions, and again, Brian was incredibly helpful. All is now installed, looks great, and sounds magnificent.

All in all, a great experience, I have already recommended them and would shop here again without any worry! Thank you to Brian and the entire crew for making this a great buying and listening experience!

Great speakers and easy to install Review by Brian
The videos on the web site made it easier to understand the install process prior to receiving the speakers. The product was a great addition to my patio and provides a great full sound. (Posted on 8/7/13)

Kitchen remodel Review by Robert Mac Murdo
Now these worked out splendidly and sound very good. During the remodel one goal was to get the stereo out of sight and move the speakers off the floor (Posted on 4/9/13)

Speakers Review by Tommy Miller
I have a rather large room with high ceilings. My celing is 11 1/2 feet high. I purchased 3 in wall and 4 in ceiling speakers. I decided to install myself and on the day of my installation I must of called to the office 3 times and each time my call was returned promplty and my questions were answered. I had questions about exact placements of all speakers (Posted on 3/27/13)
