What's your budget for the sub?

Before anything else, are you sure your settings are properly setup? You're not using subs, so ideally your fronts should be "Large" in your AVR setting. I'm just presuming because if you changed nothing from your JBL SCS200.5 setup before, it could mean that your speaker settings are still set to "Small" with a very high crossover value.

It depends. There's no one size fit all crossover freq. for everyone.
There are just too many variables, but the good starting point is 80hz if you have a sub. But since you're using your front towers as the low-end, then you'll need to experiment a bit.

Personally I'd suggest getting a sub would if movies/games are your main content sources. I'm not sure how strong that power supply is in your HK amp, so driving all your speakers full range is not really a good idea in the first place anyways.

Since it's large , and you don't have a sub, does it matter what Hz you crossover ?

Without a Sub :-

1) When you set your Speakers to  large, all frequencies are directed to your Speakers. So your Speakers get the full range. However the very low Bass (.1-LFE channel from 5.1 movies)  which is exclusive to only a SUB will be missing. That's why you are missing the Oomph you mentioned.

2) When you set to Small, Whatever Hz you set will be directed to your Sub and cut-off from your Speakers. So you won't get the full range from your speakers. And since you don't have Sub, those frequencies will be completely missing from your hearing. Not to mention, the .1 LFE will be missing as well.  Double Oomph gone.

Those are mainly 2ch AAC which shows up as PCM in your AVR. You can't do much about the sound quality as they come form all types of questionable sources, a lot of phone camera recordings even.

If the sound is too soft you could try to pre-amplify the sound by using the Manual Vol control of your Media Player device, before outputting to the AVR.

Or if your your HK speakers are full 5 pc set. then you can simulate 5.0 channels with one of your AVR Virtual surround modes like DPL II etc. Only by trial and error will you know they sound better or worse.

If BD ripped as iso you will get the same as playing back from BD. Of course the file size will be like 35GB for 1 movie

Before I forget, your HK AVR might have the feature to send the lfe channel to the front L/R. Make sure you set your Subwoofer to None and your Speakers to large, if you have not already done so.

But then you are watching only Stereo movies, which won't have the Lfe, so won't make a diff.

I'm aware of DTS support but it only can if I play DTS from DVD. I'm using media player. If I set it to bitstream, no sound will come out. I'm using optical cable from media player to HTiB. If Dolby, no problem at all.

Regarding my question, if I want to setup a new HT, what is a minimum budget I need to allocate? At least it can give me a bit of idea about budget. At least the AVR i buy will give a same result if not better compared to my HTiB. If I know about budget, then I can plan to start saving from now. I don't need a big speakers but at least it can coop with the load from AVR.

Actually it was a common issue for Panasonic system via optical. I read it in AVS forum.

I.think its not easy to find a secondhand avr and speaker. I lurking at Onkyo and Denon website. The price is around 2k-3k. May I know where can I check the speakers info? Only found a few in lazada.

its never ending upgrading

😊 too many poison in my head now haha hope not burn my pocket out http://vbizz.com/spk51wn-5ch-speaker-packa...alnut-5073.html just saw few 5.1 speakers within my budget mayb abit over 2.5k.. http://vbizz.com/spk160rw-5ch-speaker-package-5071.html searching keep going on...feel like wanna try the floor type 5.1 the Yamaha np40 I think for living room abit small..the spk51 price around rm1500 if i can get a avr for rm1400 it will be around rm2900...most probably will get it on Raya corner..😋

The sound will be totally unbalanced. Absolutely no space on the left and free open area on the right, extending towards the back. I suggest better get a HTiB and be done with it  . Save you a whole lot of money.

I don't have a good actual photo with full view of my living room. Here's the 3D rendering by my ID and what I have so far of my actual living hall, which should be good enough to give you an idea on the space. Overall, it isn't very spacious and it is a constraint.

Actual photo with partial view. The edge on the right hand side of the picture is pretty much where the wall is, which my couch will be up against it.

Nothing. Just upgraded my TV so now looking for better sound system.

At first looking at soundbar, so far 1 have these 3 in mind:

Samsung HW-K551
Sonos Playbar
Sony HT-CT-390

Then, of course got poisoned to look at AVR, so far keeping these in compare list

Marantz NR1506
Yamaha RX-V381
Denon AVR-1713

All basically entry model, I try to keep budget below 3k with speakers.

Haven't decided which speaker to buy. Once I decided with AVR, then will start to look for speakers.

Yup...my window... perhaps it has some flaws, the bass just pushes it over...

Realistically you need some headroom with power & LFE...so the adage of "can't have too much bass" is true...you can always tune it down, but if you don't have enough you'll be "stuck"... like SSJBen with his SB1000 until he upgraded...

So my advice is to evaluate your room and it's response and then decide how loud and how low you wanna go, then only find the sub to match it... remember also two subs is "better" than one, so sometimes 2x RM1.6~1.8k may be better than 1x RM4K sub for some people and their needs...

As for risk of damage... a lot can be managed, others just have to try your luck lor...
