you screen first shortlist here we give you our opinion... i'm sure you have looked or listened to a few...

i would go with more musical subs to add that extra bottom ends... no need to shake you neighbors' house down

Currently looking at Q Acoustic 3070s, not sure it is a good buy or not and I kinda agree with u, I dun need a sub tat can shake my neighbours house down 😀

option are quite limited actually..
Waderfale
Elac
Polk
Pioneer
Yamaha

Why do you need a sub?
1) if you want to have louder low mid freq then yes you can invest on 3070s
2) If you want to have more complete freq range (20hz to 20khz) then 3070 is not suitable.

your 3050i can cover the freq between 44hz - 30khz
3070s freq range 50Hz - 150Hz

meaning to say your 3070s actually falls in the range of where your 3050 is covering.. does it that means it wont make a different if you add 3070s into your existing system.. the answer is no.. depends on how you set the cross over.. you still might get double bass or stronger bass as compare to 3050i working alone.

If we are talking about music, we often want to hear all the frequency between 20hz to 20khz.. you existing setup will miss out 20-44hz freq range.. this is where we want sub to do the job to fill up the gap. ideally the sub need to cover at least from 20-150hz or even lower.

If we are talking about movies, the requirement is even higher as we want it goes lower than 20hz to bring us lfe impact.

All these are ideal case which i haven talk about the drop in certain freq at certain vol which varies from speakers to speakers.

for sub i will recommend at least get 10 inch. 8 inch min if you are using it for music only... the bigger the driver it can dives into lower frequency.. that's the general rule of thumb like bigger hp car = faster

if you can top up ur budget <2000, maybe klipsch sub is something that you can consider but it wont match well with the look of your 3050  laugh.gif
if you desperately and need to have a subwoofer, you can consider yamaha/pioneer which cost less than 1k. it can give you some lfe but you cant expect good audio quality from it..
if you have budget > 3k you can look for svs

thx for explanation bro, my setup intention was 50/50 (music & movie) build, which mean i have to look for 20hz freq range sub right ?

ideally la if you dont care then ignore.. if not 25hz to 30hz is also good enough.. most of the floor stander can do around 40hz d, you will feel it.. but find something 10inch min you cant defy the rule of physics.. u cannot bawak kancil and try to challenge 200kmh
ur 3070 is dual 6.5" it certainly will play louder at certain freq but you are missing some freq in the other hand.. by right your crossover setup should be 80hz at ur 3050i and below 80hz is sub realm.. u bought a 1.5k sub that give u 50-80hz.. might as well i pay yamaha which able to give me 25hz - 80hz that cost <1000.. of cos audio quality between the two sub is another topic to cover

unless u r really pro and you figure out you dont need the extra low frequency and you found your 3050i setup you try out all d but missing out the chunk of 50 - 100hz range then 3070i is something you can consider.

how about Yamaha SW300 sub ? for the spec it state 20-160 Hz, well i dont expect it can have good sound quality , but at least it can cover the freq that my setup lacking now.

movies are full of music too... only minuscule % of time goes into sub-bass

30hz spec subs will still give you 20hz but just not that loud

20hz spec subs prepare to spend at least 3-4k lor...

thx bro, if i got tat kind of budget, confirm i will go for the svs sub tongue.gif

i will pass on this if i were you... 35hz @ -6db won't sound that low tbh... you wanna find something 30hz/-3db, if cant maybe settle for 35hz/-3db

you got extra budget to upgrade avr?
ur sub says 1.5k budget u have another 2k in hand to upgrade avr?
my suggestion is to do it one by one.. because you buy all entry level stuff.. i dunno where is your destination.. maybe you can share with us how you want your future setup to be

my questions for you
1) What AVR you are using now?
2) Do you play games PS5/XBOX? or you want your equipment to support for it?
3) What is your future upgrades? 5.1? 7.1? Atmos - 5.1.2?
4) Does your tv support high refresh rate like 120hz or HDR10+ or Dolby Vision?
5) What kind of media you often play for movies? Bluray? Netflix? Or Jack Sparrow?
6) How big is your room?
*
1) im using denon avr-1911 which 10 years old model
2) yup with PS5
3)for now, just 5.1 setup
4) yup my tv support 4k 120hz & dolby vision
5)netflix and jack sparrow
6) about 10ft x 15ft

1911 you bought second hand? u been using it for more than 10 years but without a subwoofer?

audio wise i dont see any upgrade for you to change from 1911 to x1600h / v4a (v4a is even downgrade in terms of amplification power / number of supported channels).. the only reason you could benefits is over the picture that support 4k (which your 1911 doesnt) and high refresh rate with HDR that your PS5 / TV can support..

if you are not planning to upgrade further from 5.1 i will suggest the below:
1) focus your budget a get a proper subwoofer... at least for now i dont see technology that will make subwoofer phase out.. meaning a good subwoofer can live with you for a long time..even u change AVR/TV/PS6 later your subwoofer may still work perfect.. aim for SVS PB2000/SB2000 min
2) You got a ps5 compatible tv.. i will run my direct connection of PS5 to TV to gain the advantage over video then use ARC channel back to AVR for 5.1 audio.. ps5 is not so demanding when it comes to audio..

once you have your subwoofer d then you can plan to upgrade your AVR.. look for x3000+ series from denon.. that will give you more amplification and more channels support with preout in case you need to do future upgrade + MultEQ XT32 audyssey

plan our your journey i think most of us upgrade step by step.. learn along the way and appreciate the result from the upgrade..

yup tat avr is used, but it start having problem on the right sound channel, so i got no choice but change avr 1st and put sub in 2nd cry.gif

you made me work....  mad.gif

desa has a kef q400b, klipsch r-100sw...and few others... https://desahome.com/find.php?vipflg=N&cate...ubcats%5B%5D=SW

others... mission ms-200, monitor audio mrw10...and a few more...

priority based on spec and my pref for sealed subs... kef, mission, klipsch, monitor audio... you may want the monitor audio because got white... lol...

as mentioned earlier... for 20hz you need ~4k budget... putting in differently extra 2k to go 10hz lower...

thx bro tongue.gif btw i quite like the Klipsch R-100SW design wub.gif

if u need movie LFE bass rumble, should aim for Pb serie

else sb will let u have advantage go louder while not disturbing other house mates

Thx bro, already bought the PB-1000 Pro, indeed sound incredible, only downside it is way too big, but lucky it still able to fit in my living room
