Subwoofer: should we even use them at all?

So what is the conclusion?

The thread starter was warned against a sub due to "the lack of coherence that inheres in adding a subwoofer". I think this is system and room dependent. Bass has to be integrated anyway. There is no general rule that it is better inside a (costly) speaker than with (less costly) speakers and a sub, even if it often works out that way. So there is nothing bad that "inheres" in choosing a sub.

New techniques and faster subwoofers has given us a much higher level of integration than what was possible in the past.

I never thought that this would be possible. Now I know it is possible!

faster subwoofers? are they midranges now.lol

When you use lighter material, you get a better response. The poweramp also has influence on the control and speed.

Ceramic woofers are very light and are a lot faster than some 'slow' material used by other brands.

In a simple stereo test you can compare the differences in integration. It is so simple!

Lewinski,

I've used several different configurations, but I'm currently taking the digital signal out of my QSonix server straight into the Onkyo via coax. The Onkyo does all DSP including x-over. The twin sub out of the Onkyo goes straight to my Rythmik subs and the main out goes to (at the moment) a pair of Cary 805s and on into a pair of OHM 100s. Sometimes, there's a different amp/main speaker combo, particularly if I'm using my Maggie MMGs, which require more grunt than the Carys can deliver.

BTW, I've previously used both of my current stand-alone DACs (Cambridge DAC Magic and Benchmark) for conversion, but - as I've noted - simplicity is important to me and I prefer the simplicity of one box. As to SQ, it's audibly different with each DAC (especially Benchmark vs Cambridge) and a matter of personal taste, but I like the sound of all three options and settled on the internal Onkyo DAC for the reasons stated above.

Further, BTW - there's an upgraded version of the Onkyo from one of the specialists (Upgrade Company?) that offers an in-home trial. At the moment, I'm kicking the idea of a trial around just to check out any potential improvements. If I pull the trigger, I'll post my impressions
