Which subwoofer should I get?

ln my opinion hi level for hi-fi and low level for home theatre only.

@mylogic  That might be your opinion, but most of the top subwoofers extant from the likes of Magico, Wilson, and JL Labs whose top subs venture well north of $20k only have line level inputs.  Hmmm.  Pretty sure these guys know what they’re doing, and if they thought high-level inputs were in any way better they would’ve included them in subs at this level.  Or maybe you can explain to Alon Wolf and Daryl Wilson why their uber-expensive subs are just for home theater.  You know what they say about opinions…

Also looking at adding a sub to my 2ch system, went to my local dealer to listen to a few. Was thinking about SVS, REL and Rythmik. Of course you can't addition Rythmik unless you buy one. 

On the same system, with the same 3 songs, back to back, to back, 

Rel Classic 99 

sounded the best, disappeared into the room, fast, accurate, smooth, felt like it was hitting lower then it was. Felt like a warm blanket of bass.

SVS SB3000

BOOM, lots of BOOM, this thing had power, but not accuracy. Would be perfect, if I just listened to Techno, Rap.

JL Audio (forget the model, it was $5)

Very smooth, very accurate, LOTS of power, also most expensive. Was on the cold side. Also out of budget. 

Bowers & Wilkins - 800

Used the DPS to set it up in the room, that was cool. In between the REL and JL Audio. Good bass, good power, not as fast or accurate, not warm or cold, maybe more boom that I want.

In the end, I want the REL, it was by far the most musical, added pure bass, with out any boom, was very fast, accurate, not overpowering. Even though it hits higher over the other subs, it felt like it was going deeper. Also the fact that it totally disappeared into the room. 

Not sure how it compares to Rythmik, cost is about the same, the REL also perfectly matches my Walnut Klipsch. 

I have a Pair of BagEnd InfraSubs 18"  Amazing, sounds and service, and support, Great folks.   https://bagend.com/product/isub2-18-bag-end/

Easy to part fools from their money….

l mean $20k for a sub?

Anyhow this platform is for giving advice as we see it and opinions and beliefs.

Horses for courses, you pays your money and takes your choice. My advice opinion was directed to ‘mwsl’ who has shown his intention to buy a Rel and as most will realise on here, they do not stretch to a $20k overkill sub for a domestic environment.

My personal evaluation of Rels Neutrik hi-level input application is based on 25 years of ‘personal’ knowledge. I am still currently using two Rel T9i’s so my opinion is they work exceedingly well for me using hi-level for hi-fi.

@mylogic  Most other excellent lower-priced subs from the likes of Paradigm, Perlisten, etc. also only use low level inputs — are they just home theater subs too?  Silly.  Doubt you’ve even heard a decent sub in your room with low level inputs, so coming here and stating that subs with low level inputs are only for home theater is ignorant and frankly just a ridiculous statement, but you’re certainly entitled to your opinion just as I am to question it.
