Thanks Peter, but the FAQ's section is still not functioning. 
Being a typical American (now living in Canada) to do love my bass.... explaining my fondness for my McIntosh speakers with two 12 " woofers each. 
I was advised that I would prefer the M150's and that is now beyond dispute. However, I look forward to the arrival of the S-120 speakers for my Beomaster 4500.... allowing me to reunite my Beomaster 2400 with the S-75's that is so clearly enjoyed powering.
