Subwoofer (for the organ) on an ultra-budget system?

Some while ago, I bought a Fosi SK01 headphone/pre-amp to use with my Sennheiser HD650s, and the result in most music was (is!), to my ears, quite wonderful. I eventually decided however that it was high time I got some speakers, so that I didn't always have to use headphones, and so, being on a tight budget, last week I bought a Fosi v1.0 amp (the SK01 plugs into that) and a set of Micca MB42X G2 speakers. Again, I am very happy indeed with the result. The speakers are amazing for their size and price

I should say that I am a classical musician and listen to 'classical' music almost exclusively. Much of the music I listen to works very well for me on the setup I have described and the orchestra and singers sound as close to how I know them from 'the real world' as I could ever have wished for. However... I am a bit (lot!) of an 'organ buff' (I just spent a huge sum of money, by my way of thinking, on a three-manual Johannus organ for my house: hence why I need to be a bit (lot!!) careful about what I splash out on over the next several months). For that reason (organ), a sub-woofer would be a great addition, given that the deep pedal notes can go down to 20Hz or lower (my speakers specifiy 55Hz, as far as I remember as I type this).

But even if I did think to spend hundreds of £££ sterling (not much in the subwoofer world, I know), given that the rest of my setup cost me barely £200, there seems to me to be a serious imbalance/mismatch there. Or maybe I am overthinking it?

Anyway, anyone any thoughts on my little dilemma? What's the best 'bang for bucks' solution that would add at least some of the missing depth to the organ music I listen to? I've been drooling over some perfect units on Amazon, but, as I say....

Thanks.
 
krk S8.4 or one of the bigger models
Im very impressed with mine, mine is room corrected and sync with my main speakers

How do you wanna connect it to your fosi audio amp when it doesn't have sub out ?

Hi, and thanks. That's kind of the price range I was looking at! Maybe one of the larger models has a wider frequency response. For organ music (the main reason for my thinking of getting a subwoofer), ideally the response should go down to 20Hz, though I am not going to find any such unit at anywhere even close to the price I want to pay, unless I am lucky on eBay, I realise.

Fairly easy (from what I have read over the past week or so - not actually tried it of course) to connect a subwoofer when there's no amp output... basically speaker wires from amp to subwoofer and from subwoofer to speakers. May need to be an active subwoofer for this setup though, and it must have 'speaker-level' inputs and outputs (apparently most modern subwoofers do).

I guess if the above is not true (though I have seen it multiple times from multiple sources), someone here will say so 🙂

32foot pipe will produce 16hz & will produce 120db

... not to mention the 64' pipes of the Royal Albert Hall organ in London (an organ I once got to play: amazing sensation when the 64' pipes are selected!! Would love to try out the famous Sydney Town Hall organ, with its 8Hz 64' Contra Trombone (!!!), but that's never gooing to happen, sadly! 😏)

Looking at the SVS PB-2000 Pro - Amazon has it at £999 (the highest priuce it's ever been there - Black Friday is soon: I may wait till then and see if it comes down in price. It went as low as £699 in the past). The SVS PB-5000 R is a bit out of my price range, gasolin (£3000+), but thanks!
