What about walls?
I can report on the question: How well does it do with intermediate walls? This is obviously very dependent on the architecture and wall construction, but perhaps the following will help. I have a configuration where my primary HiFi system is separated from a secondary HiFi system by at least 3 walls for the direct path, plus one that may be intercepting the EM wave tangentially, and with a large refrigerator and double wall oven stack also in the general path.Because the exact path, or shape of the wavefront including diffraction effects, is not easily determined by me, I'll just note that the walls are mainly 2 x 4 with sheetrock covering. Many incorporate plumbing and electrical wiring. One near the transmitter has a glass covered picture in the direct path. Total distance (as the EM wave flies) is about 66 ft, slanted downward to a lower split level. If this were a pure air path, one would be well within the rated 200 ft performance limit, but with the walls it was a bit of a stab in the dark as to what performance would result.The receivers are indicating four bars reception. Sound is excellent (within the limits of all the components that are in the path). Receiver scan led to channels 001 and 002 being selected, so operation is just above 540 MHz. Standing close to the receivers in the direct path seems to have no effect on indicated signal strength.Additional items needed for my purpose included two Klark Pro 2 XLR splitters to intercept the audio signal between pre-amp and amplifier at the transmitter end, two Sescom AUD-XLR-RCA 1 Channel XLR to RCA Balanced To Unbalanced Audio Converter modules for the receiver end, and various interconnecting cables.One advantage of this direct RF approach over WiFi schemes is avoidance of signal delays; that is, speakers are synchronized. Intermediate listening locations do not have echo like sound.

frequency per channel
Alto stealth is a great product the only issue is that I couldn't find the frequency of each channel. So I had to buy a signal scanner. ill save you some time with the list belowfrequency per channel0 - 542.1251 - 543.6252 - 545.0503 - 546.4254 - 546.9005 - 548.1506 - 551.1007 - 552.4758 - 554.0009 - 556.075A - 558.975b - 559.975C - 561.050d - 562.975E - 564.425F - 565.975

The Perfect Solution for a Specific Problem - Alto Professional Stealth 1 Mono
I needed this for two specific applications: wedding ceremonies and satellite speaker situations. In both settings, I don't use extension cords and either can't or don't want to run XLR cable. The Stealth 1 Mono system is ideal for this:It sets up fastIt's easy to useIt works.I've spent a lot of time with the Stealth 1 Mono wireless system. I've tried it in many situations. When you follow the instructions EXACTLY, it works perfectly: Set the speakers where you want them. Turn the transmitter on first and THEN the receiver. IF you turn the receiver on first, the whole thing becomes intermittent.I've tested the battery life twice with rechargeable batteries. They lasted 4.5 and 5 hours before the wireless turned off. That's more than enough time for wedding ceremonies, cocktail hours and short gigs. I've also ran it 80' apart without any issues. I haven't needed it to go further than that, but Alto says it will go 100'. I've also used it with the output on a mixer to the speaker and it worked flawlessly.UPDATE: I had the same static issue as HGDJ below. But it only happened when I was using this with a Bluetooth input on the speaker to send music to it on a test. As soon as I plugged the music directly into the speaker input via a cable and sent the signal out to the other speaker via the Stealth 1, the static went away and it worked perfectly. Maybe you can't use Bluetooth AND the Alto Stealth 1 at the same time?The Alto Stealth 1 Mono solves my problem perfectly. Would I use this with the band in a critical "this can NOT fail" kind of situation? I don't think so. If I wanted a wireless speaker system for the bands FOH system, I'd go with the Alto Stealth Wireless Pro.
