So, been testing the RT5 for
a few days now. UPDATE* As of this writing (16 Feb 2016), it's been a few months.
Had many movies, TV series and a few dozen hours of gaming thrown in on it.
Disclaimer:
Before I start my impressions, let me start by saying: YES,
ANY mid-range 2.0 bookshelf speakers from KEF, Wharfedale, Q-accoustics, SVS or even Sony's own Core Series etc. etc. blah blah blah will blow the smithereens out of the RT5 and pretty much any soundbar. Before any smart allecks want to show off, yes I know.
I say that because I've gotten a few PMs flaming me on how mid-end bookshelfs > all soundbars. Yeah captain of obviousness, no shit.

Anyways, on to my impressions:
I would be comparing the Sony HT RT5 to the Philips HTL9100, this is because they are priced similarly and despite Philips phasing out the 9100, there are still quite a few old stocks left in many retailers.
I'll cut right to the chase on sound quality, the RT5 has a much better sub than the down-firing subs Sony was so fond of a couple years ago. Front firing is the design concept this time and it's for the better (at least in this case), the bass has noticeably better tightness and solidity. It's more controlled than any HTiB or soundbar subs Sony has done before.
The RT5's sub gives a decent enough low end, where it lacks however is not being able to scale properly into the low-mids. It can bleed and at times feel a bit too boomy. This is something the Philips HTL9100 does better. It's something Sony cannot ever get right, not being able to properly balance lows (in the 50-80hz region) and low-mids, there is a bleed in between but thankfully it's not as terrible as before.
How about the soundbar itself? It's a true LCR setup indeed. The L and R drivers are accompanied with tweeters, they're the same as that of the CT770 and CT780. Nothing great, but not bad either. There's good clarity, decent handling on crowded effects and aggressive in nature. It does however lack overall dynamics. There's not enough weight on the low mids (250-400hz region), so sometimes deep vocals or whacking effects may sound a little thin.
The center driver however, feels like a shoe horn. It's obvious Sony just took the same driver from the L/R without the tweeter just to incorporate a center speaker. But at least, I'm glad they did.
You see, the Philips HTL9100 was a 4.1 setup where the center channel was just a phantom. The problem on the 9100 was that the L/R does not have a wide enough spectrum, soundstage and depth to provide clear vocals. Sony solves this problem and although the center channel on the RT5 is pretty subpar, it's a game changer when playing proper 5.1 sources. The HTL9100 simply has no match for the RT5 in this department.
So, as shoehorn as it may be, the center channel is indeed important! Although vocals/dialogue do lack energy and any heft, it is at least much clearer than what a phantom center channel can only provide in a soundbar.
Which brings me to the highs, or the treble if you will. Tweeters does wonders to bring out energy in any source so that things wouldn't sound dull and muddy. I'm glad Sony didn't omit that, no matter how mediocre they might seem on the RT5.
There's decent energy in the highs, good enough that soundstage is heighten, but not great enough to really have that "cut through your soul" feeling when a sword goes through steel on screen. Or when a bullet ricochets off a wall, or a high pitch scream... none of that will make your hair stand or your body squirm, no the treble on the RT5 isn't that good. But how does it compare to the 9100? Similar I'd say. It's a limitation in design and economics. I wish there was more energy and sparkle, but at this price, I'm not particularly dissapointed to be honest.
*UPDATE*
Out of curiousity, I added some rubber floor standoffs onto the RT5's subwoofer and I was absolutely surprised by one thing: the boomyness has significantly decreased!
The sub now blends so much better with the front channels, there's depth on the low-end now without the vocals or front speakers sounding muddy at all. Most importantly, dialogue now sound less tinny and has some actual weight to them.
The rear speakers.
This is why people have been shifting to the whole soundbar 5.1 experience last year. Philips made it popular, it's credit to them where suddenly more and more manufacturers are coming out with 5.1 soundbar experiences. NO, before anybody starts, this isn't going to replace a full fledge HT setup, with subs half the size of an Ikea Gallant table. Far from it in fact.
But what the RT5 wants to provide, it provides well enough. The rear speakers aren't obnoxious in size, all it needs is a power cord and it connects wirelessly to the soundbar. Wouldn't it create drop outs? In my house of having 14 wireless devices, nope. Not once did the rear speakers drop out of connectivity. The use of a 5ghz channel is brilliant thinking by Sony, they didn't cheap out (if only they did the same with the PS4...). Their own "Secure Link" feature enables a specific frequency on the 5ghz spectrum that pretty much only a handfull of unknown wireless devices will ever touch. This is much like what Philips has done with their HTL9100 and kudos to Sony for thinking the same.
How do the rear speakers sound then? Decent at best, subpar mostly. Because most movies still do not actually record for Atmos/DTSX or 7.1, the vast majority relies on good ol' 5.1. With that, the rear speakers does a so-so job in ambient noises. There's discernible clarity, laid back in signature if I'd say. I do wish there's more grunt, better detail retrieval and more forward presentation though.
That said, I had very little issues pinpointing other guardians in Destiny during Crucible matches on the map, front, sides or back. In games like MGSV where stealth is important, audio cues are crucial. Again I had little issue pinpointing where enemies are when hiding behind an object without relying on the use of the sonar. The problem is they just don't sound very immersive.
So what else does the RT5 has going for its price? How about 3x HDMI inputs with 4k60p passthrough? That's both good and bad news. Good because 3 HDMI inputs is rather generous for most people getting a soundbar setup. The 4k60p passthrough though? Well, you can pass 4k60p so long the content is in 4:2:0. There 4k60p at 4:4:4 is not possible on the RT5 unfortunately. And no, there is no HDR support.
I do not know of any soundbar at the RM2.4k segment that also has as much features as the RT5. NFC? check. Bluetooth streaming to devices? Check! Screen mirroring via Google Cast? Yup. Every major audio codec from the traditional DD5.1, DTS, to lossless codecs like DTS-HD MA and Dolby TrueHD, all CHECK! Sony even gave people the option to upmix stereo sources to multi channel via Dolby Prologic OR DTS Neo. Yeah, it's nothing special given entry level AVRs provide these kind of features, but on a mid-range soundbar? WHERE do you even find this?
On price alone, the Sony HT RT5 is unbeaten. RM2.4k is the SRP, places like Harvey Norman are selling at RM2.2k (or even less if you know how to bargain). In comparison, an entry level Yamaha NSP40 5.1 speaker set + Yamaha RXV379 would cost in about the same region as the Sony HT RT5. But sound quality alone, the Yamaha set is only marginally better with some trade offs.
The multitude of features, a decent listening experience, and a good price, there's not much Sony has done wrong on the RT5 I feel. Every once in a while, Sony comes up with a good product for its price but sadly they always become inconsistent with it.
I do still need to spend at least a few more weeks with it to come up with a definite conclusion, but there's no doubt in my mind that the RT5 is a great system for what it provides and its price point. Sony has Philips beat, where the latter's B5 (this year's version of the HTL9100) is somewhat of a disappointment, costs more and has limited functionalities.My conclusion on the RT5 is; The RT5 isn't bad at all, but it's no where great either. Action movies can be quite immersive, games can be really fun to play. Music is the weakest point of the soundbar simply because the drivers just can't hold its own in stereo mode.
In some aspects, it shines but there niggly things that keep it from becoming a perfect entrance for surround setup beginners.
If you have a budget of RM2k or so, but absolutely want a 5.1 experiece without the fuss of a proper home theater setup, then the RT5 is for you.
Anymore than that then I'd suggest you look at a good pair of bookshelf speakers and a decent amp or entry level receiver.
