“We are going to do a review of a product. This is the first one actually so if you have seen a number of them, this was the first. This is for a pretty cool product from JA Audio called the EXR6T. And I’m just going to open it up from the beginning how you get it and show you some of the cool things about it. Let me show you what the box looks like. It’s well packaged, there is good information on the side and we are going to go over some of these specifications. Inside you have one pair. They sell just like shoes. We wouldn’t sell you just one shoe. So you see that speakers come priced by the pair. As you open it up, you’ll see an instruction-installation guide from JA Audio. And some of the tools that you are going to need to install this. It comes with two templates. These are both painting shields. You can put this inside your grill, paint the outside. You don’t paint the grills being on the speakers, don’t leave them to the painters, do them yourself. You place it in the middle here and you’ll be able to paint around the edges without getting the middle painted, and then you also have a template for your cut-out. You put this on the ceiling and you trace around it , and then you have your cut-out. That’s how those work.
Also inside you’ll find two individually packaged boxes. And each of these contain one speaker. We break these up into singles and sell them to you for surround systems. So you can have a center channel for the ceiling. You can have five round speakers if you want. Inside you see these, pretty well packaged, I never have any problems with these getting to you all dinged up. It comes out of its cellophane wrap and we’ll take a closer look here in a second.
Now we have the speaker out of the package. Let me show you some of the parts about it. You’ll notice two little bags of interesting parts. One is a little wire sort of things like this and this will help you get your grill of. And these… we get the most amount of calls about these pieces… inside there are little, sticky, black things that help you if your grill is a little loose. You stick these in the channel of your grill. It helps firm up the grill. Inside of here first thing you’ll notice in the back is the crossover. This allows low frequencies to go to the woofer and high frequencies to go to the tweeter. This one is a 12 dB crossover. You can always tell the 12 dB crossover because you got a cap and a coil for both sides. Some resistors in there serve some other function; allow you to drop it 3 decibels either up or down. This is how this all lays out. It’s really nicely laid out. You can see the bezel is a little deeper and the back is able to pivot inside. Little trick to take of these speaker grills: You take these dog ears and twist them out. You use these to push to the front and the grill pops right out. You’ll notice on the grill first of all that you have this backing in here. It’s a little piece of fabric. What that does is it enables the speaker to be hidden underneath there without having to see the blue or purple and everything that’s inside. It kind of hides real nice. There is a little dome shape to this one. It’s to help the function of this going back and forth. Some basic things on this is, one it is pretty cool how it pivots. Inside the frame it moves the speaker while it’s installed in the ceiling even and put it any direction that you want. It goes all the way around. You can push it wherever you want to push it. It’s important that the whole speaker pivots because if you just move the tweeter like most of the other speakers have high frequencies going one direction and mid and low frequencies going the other. And the problem with that is that you get what’s called an off-axis response and sometimes you’ll hear phase problems, you’ll hear frequency echoes, weird hollow points in different frequencies. So if you have a regular tweeter that doesn’t point, keep your tweeter pointing straight out. Sounds better. Here we’ve got “W” and “T” -3/0 and -3/0. What that enables you to do, you got two, no actually three settings. Flat you have one lower and tweeter the same. So this will enable you to give a three decibel drop to the woofer. It’s going to sound higher. And also give the tweeter a three decibel drop and put it at zero flat over here if you have some sort of volume problems. Three decibels, that’s the first level of sound that we can hear. So we’ll notice that difference when you switch those.
It’s got a fiberglass cone. It’s got a butyl rubber surround. That means it’s a very, very flexible and very, very durable type of material. It enables it to go in and out, in and out, many many times. It also has a titanium tweeter. This is a one inch dome titanium tweeter. They call it 25 mm. That’s the measurement across here. This is a 6.5 inch woofer. We call these 6.5 inch speakers, that means the woofer is 6.5 inches in diameter. That doesn’t mean the overall dimension is 6.5. Actually these are closer to about 11 inches. They are about six inches deep, so these won’t go into walls. But they will go into ceilings.
In summary on this speaker: We got a nice 6.5 inch pivotal, fully rotating in-ceiling speaker. It works as an infinite baffle, that means it goes into addict spaces,and in between joices. It’s got a one inch titanium tweeter, a fiberglass cone 6.5 inch in diameter, it has a high end 12 dB adjustable crossover for woofer and tweeter. That means it gives you 3 decibels up or down on the woofer levels or tweeter levels. Its frequency response was measured at 52 Hz on the low end and up to 22,000 Hz on the high end +/- 3 decibels, along that line. Power handling is up to 100 watts. Sensitivity or what they call efficiency is 88 decibels per 1 watt. And this grill is made out of aluminum, so it won’t rust, you can use this outdoors as long as it is not in direct contact with water. It is about 11 inches in diameter and six inches deep. Cut-out dimensions are about 9 1/4 inches. You don’t want to be doing any cutting until you get this and use the templates provided.”
Q & A
It's a regular speaker. See this for more on wireless capability: https://inwallstore.com/how-to-install-wireless-inwall-speakers/
I needed to replace my old center channel speaker and found what I felt would do the best job I read the reviews and also compared the spec since I needed to upgrade and improve . the speaker arrived very quickly after I place the order it was installed right away although I did get help since I had to open up a larger hole and did not want to mess up the job otherwise it was a quick install and blends well in ceiling About the sound IAM using it for the center channel the bigger twitter and being able to adjust the angle and frequency have made an improvement in hearing dialogue . Hope this helps
