![]() ![]() I needed to find a way to jury-rig a similar effect for a fraction of the cost. Unfortunately, the asking price for that Trinnov processor is absurdly beyond my budget. The better solution is to install additional speakers in the center between the other height channels (Top Middle position). Those speakers are now fixed in place with wiring through the walls and ceiling, and I can’t move them without remodeling the room. This issue is compounded by the fact that the locations where I had installed speakers when I built the home theater (before immersive audio was a concern I gave any thought to) were less than ideal for Atmos. That, combined with a low ceiling, makes it difficult for just four speakers (two in the front of the room and two in the back) to image a sound above my head convincingly. My own home theater is a long room with a lot of space behind my seats. While this is also true in acoustically neutral environments at high volume, tonal balance switches to a canny sonority with resonant midrange.Nonetheless, for some of us, a limit of four height channels isn’t enough to fill the top of the room with sound. In a reverberant environment, like a kitchen or bathroom, the RP4 is even more boomy and muffled. It suits male voices better, matching low midrange presence with enough clarity. In the podcast use case, female voices sound unnatural because the device makes them boomy and muffled. This is somewhat disappointing considering the dimensions and heft of the device: it weighs nearly six kilos. Despite the presence of bass, the tonal balance lacks low end and extension. The midrange is unclear and dark - there’s too much emphasis on the low midrange. By putting the device on the floor, you can actually improve the situation somewhat because the treble seems to travel upward. With a lack of treble and high-end extension, the device can sound “boomy” and muffled. The timbre performance of the RP4 put a line under the boom in its name. But its results revealed some interesting quirks of character. In general, the LG XBoom RP4 performed well in this attribute compared with other similarly priced devices. ![]() The LG XBOOM RP4 falls into the Advanced category of devices in the DXOMARK Speaker rankings. (For more details about our Speaker protocol, click here.) Note that we evaluate playback using only the device’s built-in hardware. This article highlights the most important results of our testing. Speakers: Two - one upward-facing tweeter and one upward-facing wooferĪbout DXOMARK Wireless Speaker tests: For scoring and analysis in our wireless speaker reviews, DXOMARK engineers perform a variety of objective tests and undertake more than 20 hours of perceptual evaluation under controlled lab conditions.In this review, we will break down how it fared in a variety of tests and several common use cases. We put the LG XBoom RP4 through our rigorous DXOMARK Audio test suite to measure its performance at playing back audio. The brand says that the battery offers 10 hours of listening enjoyment on a single charge, and it comes in several colors. The LG XBoom RP4, which also goes by LG XBoom 360 in some markets, is an omnidirectional home speaker that comes with an ambiance-creating light show as well as a “DJ Effect” setting on its app, which allows you to mix samples as well as adding scratching and other sound effects.
