A full range speaker?
@mozartfan - I'm glad you found the chart useful.There's also a comment somewhere above that sub bass isn't audible... sub bass is generally (perhaps not universally?) understood to reference the lowest two octaves which occupy 16-62Hz, most peopl... 
A full range speaker?
This may be useful for some - here's a Sound on Sound page with a link to a frequency chart in the top right corner. Fundamental notes are within the range of 16Hz to 9kHz, with harmonics going much further up in frequency. If you don't listen to ... 
Looking for a 2-channel high end volume control
I've done a fair bit of research into this, there are a few available... the TI range is listed here. I think Maxim might do some as well. The advantage of IC volume controls is that they track well, are cheap and small. The audio performance is n... 
I really could use some help here.....
I'm not sure if this answers your question but here goes...Your preamp sends the signal to the sub which has a low pass filter so that it's own driver plays only low bass frequencies. It also has a high pass filter to remove the low bass frequenci... 
Thoughts on Active/Passive Speakers? Looking for pros and cons.
Lonemountain - no problem, appreciate your response. 
Thoughts on Active/Passive Speakers? Looking for pros and cons.
pragmas: signal processing at speaker level is a WHOLE different animal than at line level.Yes I agree, that's what I said.Have you seen a proper passive crossoverYes lotsIt is NOT a disadvantage for seperate amp for each driverAs long as you don'... 
Phasing a biamp system
If you have speakers designed to be biamped, and you are not using a line level crossover simply assume the speaker's inputs are correct.+1If you bypass all the crossover components then there's a lot more to do along with phasing... BTW in a loud... 
What are some good sources for buying new LPs and CDs
+1 discogsThere are loads of independent record stores you can browse and if you're looking for something specific you can even search for a particular pressing. 
testing a crossover
If you measure the resistance across the loudspeaker posts which include connection to the bass driver (or full range) then you will measure some resistance that is greater than 0Ω which is made up of the crossover components and the voice coil re...

ps was that pragmasi or eric which posted the equation post ?That was me re-posting Eric's advice to point out how it wasn't very helpful. 
testing a crossover
1) Original test with everything assembled showed 0Ω resistance across the MF/HF +/- terminals on the back of the speaker.2) Those terminals connect directly to IP+ and IP- on the crossover PCB.3) With the crossover disconnected the DC resistance ...

Pragmasi-im really sorry,but there are no open circuitsAbsolutely nothing to be sorry about at all... would just be good if we could help you fix this.shorting links on speaker binding post havent ever been used,to go from bi-wire to normal two wi... 
testing a crossover
@erik_squires Dude, you should have followed my advice and you'd be done by now. :)The best way I know of to test a crossover is to generate an impedance graph. You can use DATS V2 (or is it now up to V3) or you can build a jig and use Room EQ Wiz... 
testing a crossover
between the HF+ and LF+ terminals should be 0.0 ohmsdo you mean open circuit?.. Not being snarky, just checking :-).You have made me think of something though... if you forgot to take the shorting plate/wires off the loudspeaker posts when switchi... 
testing a crossover
Okay... I think I am having trouble following. Also there might be a bit of confusion around resistance (DC) and impedance (AC). When you read the resistance across the loudspeaker terminals it has very little to do with the nominal impedance of t...
