Does full range guarantee bass?

I have full range speakers. Monitor Audio Studio 60's.
They are rated 26Hz to 20Khz. I auditioned them at a Hifi store with a McIntosh MC2102 Tube amp and the combo sounded great and had pretty good bass.

I took them home and connected them to my Proceed AVP2+6
pre-amp and Anthem MCA-50 5 channel amp. The front end
was a Yamaha s2300 Universal Player.

This set-up sounded pretty darn good and had pretty good bass. The McIntosh sounded a bit better, but only fractionally.

Next, I upgraded to Krell FPB 350 MCX monoblocks for my
front two speakers, the Studio 60's. The bass response
now was so big, I was able to turn my sub-woofer completely
off. The Krells produced deep, tight bass, and suddenly
my speakers could rattle the room like my sub-woofer used
to. Ultimately, in my system, it was too much of a good
thing, so I switched to Levinson 436's. In my system,
the Levinson's bass response was "just right." Still
deep and tight, can still rattle the windows at times
when the music calls for it, but -- for want of a better
description -- the Levinsons disappear and don't call
attention to themselves as much.

Yet, I felt the Levinsons were just a tad more laid back than I wanted. I missed a little bit of what the Krells
were giving me, but I didn't want the full Krell treatment.

I have ordered the Meitner Dac6, but I bought my brother
a Sony SCD XA777ES SACD player, used, here on Audiogon so
I threw it into my rack to make sure it worked properly.

The difference between it and my Yamaha Universal Player
is astounding. Everything, from top to bottom -- for want
of a better expression -- snapped into place. Now, the
speakers and the amps are doing the disappearing act and
the bass response is more accurate and satisfying than ever.

Lesson learned? First, your speakers have to have the
capability. Second, you need proper amplification.
Third, your front end also makes a big difference.
Fourth -- I am still using 12 AWG Copper Speaker wire
and $15 interconnects and I have amazing sound staging,
excellent detail and focus, and extremely satisfying
high and low end extension. My advice: Don't be another guy with speakers rated only down to the 40's, trying to produce bass with expensive cables. Or, another guy
with full range speakers, but without proper amplification, trying to produce bass with expensive cables.

I agree with Stehno. I would rather have some bookshelf
speakers than other full-range floor standers. I'd rather
have no bass than bass done poorly. The task is to find a pair of speakers that are not only "full-range" but are
also coherent from top to bottom, produce deep, tight, and
above all -- musical -- bass in a way that doesn't muddy
the mid-range, and handles detail and dynamics in a way that sounds accurate [or -- gasp -- pleasing] to your ears. Also, if you plan on extended listening sessions, make sure you can listen to them for extended periods without fatigue. THEN, find the right amplification, pre-amp, and front end. Spend hours at your local Hifi stores
listening to as many speakers as possible. Don't limit
yourself to speakers in your price range -- try to listen
to speakers at higher price points to see how they handle
coherency, bass, dynamics, etc. Then, try to get as much
of what you like at the price point you can afford.
