The importance of a good subwoofer

[E-Stat]

I'm sure it comes to no surprise to anyone who has read some of my past postings here, that I'm an avid fan of the Dahlquist DQ-10. Few speakers have maintained their reputation as have these babies, and they are still often compared to others costing far more, and do very well in those comparisons.

I have always enjoyed their sound since I sold them back in the 70s. Wasn't crazy over the piezo, but they were easy to disconnect.

So, what's the point of all this rambling? In Definitive Technology's lit with the sub, they make it very clear that there's no "right" setting for the crossover points, nor the level, and that the user should experiment with those settings. I always exercised caution, and kept the level settings on both fairly low, but now realize that was a big mistake.

I'll add to your recommendation: getting the upper bass / lower midrange right is critical for the natural reproduction of many instruments. I have a pair of powered subs (really bass modules since they run out of steam around 35 hz) in the HT system mated with some small monitors. I experimented greatly with the high pass to the mains, low pass on the subs, and finally used EQ to ensure the smoothest overall response (there were two peaks and valleys between 60 hz and 160 hz) This I verified with a Rat Shack SPL (using adjustment curves) and calibrated third octave test tones. While my approach is not as accurate as using a high quality RTA arrangement, it nevertheless ended up with a very natural sounding result.

So, unless anyone owns a speaker system which in and of itself is capable of reproducing extremely low frequencies...

I am quite fortunate in that the in-room response of the full range electrostats in the main system is virtually flat to 25 hz (completely disappears below that though) which is quite sufficient for my tastes. Albeit at far less than ear shattering levels (peaks in the low 90s) possible with Sir TtT's big horns or Flo's giant Apogees!

I know this thread is old, but I must ask Sir Terrence a question...

How did you configure the m-508 to run the sub? Did you bridge it?
