Bookshelf speakers with the best bass...

Agree with position and stands as issues. Direction of port can also be an issue with bass and room placement. The Tyler Taylo reference has a front port which makes it easier to place near walls.

I own both the red rose and the ref 3a. Both have extended bass response for their size, but little else in common. The red rose is much smaller. It is also much more "forward" in character and requires much more amplifier to function properly. (I use the ref 3a with 11 watt set amps, the red rose speakers require a push-pull or ss amp.) So, depending on your taste (forward vs polite) and amp/room size, you will likely find one of these speakers a much better choice than the other.

Try the Revel M20s ($2,000). They put out very tight bass,
and they sound "bigger" than their size would suggest. But some find the midrange and treble to be a bit forward. They definitely are exceptionally clean sounding speakers with good dynamics.

I'd like to hear how the Dynaudios (1.3 SE)compare to the Revels. Anyone heard both?
