Subwoofer

120 hz looks to be about the average crossover cut off point on many commercial subs. They are capable but you will create unwanted over lap and have problems integrating them. At least that has been my experience. When subs are set too high for the mains they stand out as less of a seamless integration. Especially true while using full size floor standers capable of going a lot lower.

In the past we only sold Rel subwoofers. We never went further than about 50hz-60hz.

Based on surround we went to 80hz. I never thought about using it further than that. Until a client of mine phoned me in 2012. He read about an article about using subwoofers till 120hz.

Before I tested it I said that I thought that it could make a possitive difference. After my tests I knew.

These days all subwoofers I sell I use till 120hz of sometimes even 140hz. Even in stereo use I have proven that it makes a huge improvement.

These days I use the best professional lasers to work at mm. precision and professional roomcorrection. Without these tools you cannot work precise enought to use it till 120hz.

Beside this you need subwoofers who use ceramic/aluminium drivers.

When you can measure the subwoofer with the speakers togheter you can create a much better timing.

received my Monitor Audio PL500s and can honestly say, I don't need a sub. I'm really happy that I sold my subs. This is my first "full range" speaker and right out of the box it sounds very good. I've posted a picture under virtual systems and will make further comments once they break-in.

Nice to hear you bought the Pl-500. I will send you a personal messsage when I have tested the Pl-500 and PLW215.

With the exception of Bo, pretty much nobody would use subs into the low mids as it isn't necessary and is simply not going to sound right. If you have very bass shy monitors you might put the subs up to 80hz or something but beyond that it gets weird (try it). Boo uses digital EQ to get whatever results his golden ears require so I imagine that's a key element of his take on what sounds right. Another note on driver "speed"…clearly, doped paper cones can be extremely light and sound amazing (new Wilsons anybody?) and the utter lack of understanding how drivers work is a hallmark of Bo's imaginary world.
