Want More Bass

Newbee,
I want to add to your thought about low volume listening and the KEY point in this case turs the AMP and the AMP only. Less-likely speakers are not rated conservatively and I feel the case is that speakers now don't even rich 65Hz and starve for more power.

Seems to me there are two key lines from the original post.

1. "(My current speaker's bass response is rated at 50hz.)"

So, based on their own rating, these speakers are missing the lower octave.

2. "Got a new Rogue Audio tube amp and preamp. (88 and 66 magnum). Used to have a solid-state integrated that seemed to have more bass output."

Here is a common complaint with regard to tube amplifiers,
they have a tendancy to be weak [or flabby] in bass. Tube
proponents often give up deep or tight bass for reputed
advantages in the sound of "tube mid-range."

Now, this brings up another point. Already, some posters
are counseling cable and power cord adjustments to give
this system more bass when the speakers themselves are
rated to only go to 50 Hz. This, IMO, is how people get
duped into blowing a lot of unneccessary money on cables.
Cables will not produce low bass in speakers that are not built to accomodate it.

Here is another key line from the original post:

3. "Used to have a solid-state integrated that seemed to have more bass output."

We can deduce that the former amp was better at maximizing
the speakers' bass down to its rated 50 Hz, while the tube
amp is having trouble.

The first thing I would advise is getting speakers capable
of producing the lowest octaves of bass, or as close as
possible given the price constraints. That's why I suggest
full range speakers.

Second thing; I would consider a change in amps. If the current amp is having trouble producing base down to 50 Hz
and you want more bass, I question whether you will be happy
with this amp.

3rd: It is nice to have a sub-woof for the lowest tones
and home theatre effects, but it is hard to find sub-woofs
that can do more than "thump." Further, it is hard to
tune them into the system unless you can set the crossover,
level, and phase perfectly.

For this reason, I also suggest getting full range speakers, to lessen your depedance on the sub-woof.

IMO, it is better to buy speakers with bass already integrated in a way you like, and there's a better chance
you will be happy with the crossover and phase, as well
as a better chance of having speakers that can make music
with the lower octaves rather than simply "thumping."

By all means, get a sub-woof -- after you find full range
speakers and an amp that can drive them. After you've
found a pair of speakers that can produce bass at least
into the mid-twenties, an amp that can drive them, and
a sub-woof that can give you detail and not just "thump" --
see if you still want to try to get wires to do this for
you instead of the components that are designed for and
capable of doing these things. If so, and you still have
money burning a hole in your pocket -- THEN -- experiment
with some wire and cable.

That's my suggestion.

Naysayer has obviously never experimented with cabling to improve system synergy & has no idea of what this can do, yet advises against it. Hogwash...

Try moving your speakers closer to front wall. I think the reason tube amps don't work well with modern speakers is because of smaller enclosures which, for the most part, produce "less" bass. People didn't want two BIG speakers, and I do mean BIG, in their living room when the big change from mono to stereo came along. If you look at old of houses with mono speakers, you'll discover most speakers were shoved against a wall.

Also, you might try "tube rolling."

Bob ... why must you always flame people who disagree with you ? I also have found that cables can improve a system that I'm already happy with, but will not rescue a system which I'm fundamentally unhappy with.
