Dear Guy:Check the specs. on your speakers.i.e.how low they go.And not the+or-6db figure.That means you would have to turn it twice as loud,and your mids and highs are twice as loud now,so the bass is still lagging.Do the test disc thing.You got test tones@ 20 30 40 50 cycles.You will hear when the loudness dops off.That is where your sub should be cut off.Most people aren't aware there is no "music"down below,say 35.You are actually looking for good low mid bass.Subs are quite a can of worms;save home theater use.To get one to work properly it needs the same tone/colors as your main speakers. That's where you get mud.Remember that down 3db@ down6db@ even tho it is down the whatever it still muds things up in overtones.(Both drivers producing overtones of the same note)By the time you have eliminated that you got bass suck-out.Good simi expensive tube amps do bass well.But good bass starts right at the source.CD players, DAC's, cables,power cords,pre amps,and speaker cables,all matter.Don't think for a minute they don't.Oh ya,and speakers have to be good enough to pass all this to your ears.Then there is room and placement,and room nodes.Another time for that.
What freq.do tube amps loosen up in bass
Wouldn't mind trying a tube amp but I like my bass. Always hear that they just aren't as tight or deep as a ss amp. At just what freq. does the bass begin to suffer? I use a powered sub & wonder where the crossover would need to be set so the loss in bass wouldn't be noticed ( I crossover at 35Hz now)Thanks to all
