Bookshelf Speakers with the decent bass

Can we stop ankle biting and address the OP's questions? Seriously. I hate it when people hijack a thread for their own aural-ideological differences.

+1 Simao. It seems that for some it is just too easy to take offense to something posted. Almost as if they are looking for that opportunity.

Topen, I tend to agree with J135, in that with your budget of $4000 you are in a position to find an amp/speaker combination that better provides what you are seeking.

What you have would seem to be pretty good on paper in regards to bass for a room that size.

What aspects of bass are you looking to improve? Low end extension and/or quantity? Quality/detail articulation? Or maybe all of teh above?

Or another way to ask it is have you heard a system anywhere that has the sound you want? If so what was the setup that did it?

Its much easier to hit a target if one knows exactly what the target is. "decent/better" bass alone is not much to go on.

Thanks.

That's the right question. I am looking for the speakers
with low end extension and at the same time to keep quality
of the Focal highs. Again, I really like the sound of the NAD, punchy bass and extended highs after I replaced the stock jumpers. Two days ago I received private E-mail from the
one of the fellow Audiogoner with the suggestion to try
Carbon 7 SE Speakers. Bass goes low to 38 Hz but he is not
sure how they would sound with the NAD C356.

The logical choice then to extend teh low end yet retain the would seem to be larger Focals in the same line.

The other affordable Focal line I have heard and like a lot is the Profile line. Check the specs, measurements reviews of particular models to identify the larger ones, most likely two larger floor standers rather than the smaller monitors, with more low end extension.
