What subwoofer to go for and do cheap amps affect bass quality?

[cat]

Can someone explain what "boomy bass" really means? Is it just some loud noise that doesn't translate to physical impact? Do you hear it more than you feel it or does it have the same level of impact?

If I'm getting this right, "boomy bass" refers to having a lot more bass around the 40Hz range, right? That sounds like a good thing! since I'm after that body-rumbling, chest pounding bass, it seems like it could be just what I'm looking for!

When it comes to proper bass, are you supposed to only feel it and not hear it? Is there a term for this?

I have a budget of 1 lakh, and I want bass that's powerful enough to run through my body. Since bass is my main priority, I plan to put most of my budget toward a powerful subwoofer. This means I’ll skip an AVR and go with a 2.1 setup powered by a budget Fosi amp with a sub-out.

Will using a cheap fosi amp affect the bass quality? Could it limit the subwoofer's potential/performance?

I’ve heard that different amps or AVRs can impact how a subwoofer sounds, but I’m not sure how. Since an active subwoofer doesn’t need power from the amp, it just needs signals to produce low frequencies aka bass, right?

Do different AVRs or amps actually make a subwoofer sound better or worse? Does a budget Fosi amp send a lower-quality signal compared to an AVR, or is there no difference in how it affects bass?

The room measures 17 by 11 feet with a ceiling height of about 10 feet. Do you think a subwoofer within this budget can fill the space and provide those deep rumbles or chest pounding bass? If not, how much more would I need to invest, and which subwoofer would actually deliver that kind of performance?

You can look for SVS sub woofers they are one of the if not the best in business.
PB1000 and SB1000 are two options at that price.

Also the boomy bass you are talking about is probably, bass on much high frequencies, almost mid bass territory.

Think of it like mid bass = Punch, (Dub-Dub)
Sub bass = rumbly, the kind of earth shaking, vibrating sensation you get. (Brrrrr-Brrr)

It's easier and cheaper to get good mid bass sounding subs, but for proper subbass requires frequency lower than 30hz, now that comes expensive.

If you want chest hits you should look at subs that does midbass well. There used to be midbass modules available. But not sure if it is still available. Professional subwoofers doesn’t go low but has midbass enough to give hit to the chest feel.

Is this mid bass powerful enough to produce a strong rumble that I can feel throughout my body instead of just a weak vibration in the seat?

I'd prefer body rumble over chest hits.

If you are looking for body rumble bass in movies, you will have to go with a AV Receiver as it will decode the .1 LFE channel too which a stereo amp cannot do. For just music, you are better off with a stereo amp with a subwoofer out.

There are things like "bass shakers" to be fitted underneath the seat for that body rumble.

The amplifier power required will depend on the effeciency of the woofer. If you have space to accommodate an open baffle subwoofer, then these are very efficient and dont need much power. SB Bianco OB350 will be perfect for the job :
