New spreakers sound great But

i went through a similar not-enough-bass crisis when i switched from a parasound amp to the rotel rb980 to power my naim arrivas (which actaully extend quite low). the after much experimentation and a lengthy forum thread, i ended up adding a sub, which improved matters; however i still suspect that the rotel is just not a good low end performer and i'll probably replace it one of these rainy days.

This question is worthless w/o some qualifying criteria:

1)What are the speakers in question?

2)How big is the room?

3)Where are the speakers located within the room?

4)How much bass extension would you consider adequate?

Help us help you......

Shakey

efficient speakers don't have bass unless the woofer is 12"+ in diameter.

Don't think it is a worthless question. The man just bought a new pair of speakers, the room size is not going to change, the speaker location may change but not improve bass significantly, bass extention can be adjusted bass on what sub he gets.

quick fix. bottom line..get a sub

I had a brand new Rotel RB-1582 (200 watt amp) and RC-1580 preamp with B&W CM7 speakers and even after break in, there just wasn't any bass. Being unwilling to add a subwoofer, I replaced the amp and preamp with an integrated tube amp. The bass increase was so dramatic I had to add bass traps, even after pulling my speakers away from the wall for a total of 24 inches from the wall.

The other posters are correct in saying you should get a sub IMHO.
