Do I need a sub?

Minimum.
Zardoz....Is your dog by any chance telepathic?

I suppose most A’gonner’s live in suburban houses where bothering neighbors isn’t as much an issue for city dwellers like me. You might however have to contend with bothering people in the house.

Bass is the hardest thing to contain as bass waves are close to 30 feet or longer.

So you might want to consider the ability to easily tailor how much bass any prospective sub is putting out. It really comes in handy, in that you can fill out a bass shy recording, or add a little bass if listening at low volumes, cut it down at night if there is the possibility of disturbing other people.

All the other posts here are great advice about getting the best bass, but I thought I’d point out something else to consider.

Ok, found an absolute steal on a BIC AMERICA V1020 sub.

 A steal!!!

 My only quarrel is with my preamp, there is no sub hookup, so I will have to do the speaker wire to sub, and back to amplifier thing, which sucks.

i much prefer the rca from sub to preamp, but nope,.

is there an easier way........besides getting a new pre. My pre is wicked! McCormack LD-2 , a great pre!

First sub in 20 years.
first was a 12” cerwin vega front firing 
long times ago.

  Hoping this will add some low end.

 Even. My sanders sound pre does not have a sub iinput,
or my old onkyo p308.  
Such a shame, I. Have to do the wiring exchange for the sub.

 I very much like the rca automatic sub thing, but my gear won’t allow it.
and no I’m not changing, my stereo sounds amazing, and took me 35 years to get where I’m at these days.

Hooking up a powered sub.

 All my preamps are older w no dedicated rca to sub.

 Dislike the wiring amp to sub, then speakers from sub to amp.

is there a better way?
