Full range or subwoofer with bookshelfs for best bass at low to moderate volume?


I have an older subwoofer with bookshelf speakers and the subwoofer is dying. I listen mostly at low to moderate volume and am in the middle of changing over my system as my Pioneer Elite VSX 49 TXI receiver was degrading, also due to age. My question is whether a subwoofer with bookshelf speakers or full range speakers produce more bass at low to moderate volume? 

Current system:
Moon Audio 250i integrated amp
Angstrom signature 3 speakers ( 6.5", Seas drivers, 86 DB, 6 Ohm)
Paradigm subwoofer (needs to be replaced)
Denon 2910 used as transport
Looking for an analog sounding dac at this time

"Though I’m a fan of Dr. Geddes and Duke’s implementation, the above quote isn’t quite true. The vast majority of systems use parametric equalization to manage room modes. Both approaches have their place."

It is true that the vast majority of systems do use parametric equalization.
But your statement implies that parametric equalization is as effective as a DBA system in managing bass room modes. This is definitely not true.
A parametric equalizer, at best, can optimize bass response at a single location or sweet spot. Wherever the calibrating mic is placed will be the only spot in the entire room where bass is optimized. Get up and walk anywhere else in the room and you’ll be disappointed in the bass response.

A DBA 3-4 sub system will eliminate the vast majority of bass standing waves in any room, optimizing bass response in the entire room. There’s not a bad seat in the room.

Both may have their place but they are not even close to equal.
Comparing parametric equalization to a DBA is like comparing a band-aid to a total cure.

I stand by my statement.

"Willland, thanks for the offer. The subs you listed are older and I am not looking for anything over 3 years old."

@mtloriginal,

Not selling, just wanted to show you that good subs for good deals can be found on the used market.

bob_reynolds,

" There is no approach that will produce a smooth bass response everywhere in the room and there is no need for it."

Let's investigate your sentence for truthfulness. It requires breaking down because your single sentence actually contains two statements that are false:

1. " There is no approach that will produce a smooth bass response everywhere in the room"
     Yes there is.  It is called a Distributed Bass Array (DBA) system that consists of 3-4 subs strategically positioned in the room and it does exactly what you claim it does not do; it produces a smooth bass response everywhere in the room as a result of removing the vast majority of bass standing waves which are known to cause bass peaks, nulls  and cancellations in typical rooms.
     This was theorized and empirically tested and proven by two PHD acoustical engineers. Dr. Earl Geddes and Dr. Floyd Toole, years ago. Their theory, methodology, testing experiments and results are thoroughly documented in the White Papers they subsequently published.  Their results have since been independently verified numerous times.  

2. " and there is no need for it".  What there is no need for when utilizing a DBA is any mics, room analysis/room correction software, room treatments or PEQ.  I think many members and audiophiles would likely disagree with your statement that there is no need for a hi-fidelity state-of the art bass system that is able to accurately and seemingly effortlessly reproduce the full spectrum of bass frequencies in any room without the need for any equipment or software assistance.  

   I'm surprised that you, as an admitted 'fan of Dr. Geddes and Duke's approach', apparently know so little about their DBA approach and its simplicity and effectiveness.

  Sure, not everyone can accommodate 3-4 relatively small subs in their rooms that a DBA requires, but this is a separate matter.

 Yes, the DBA approach may not produce smooth and accurate bass response literally everywhere throughout the entire room.   But, as a user of the Audio Kinesis Debra DBA system for the past few years, I'm not aware of any position in my 23 x 16 room at which bass response is poor.  There may be a spot or 2 but I'm not concerned since it's definitely not at any of my room's 6 seating positions.

     The only need for parametric equalization (PEQ) in a DBA system is for bass exaggeration or attenuation based on personal preferences.

Here is the best value that I've seen in along time.... SVS marketed this model for Black Friday last November... They retailed it somewhere around $1200... This company bought all they had left... $399
