Rel vs. Vandersteen vs Audio Physic subwoofers

Hi!

Unfortunately I can not listen Vandersteen subwoofers. Take into account that I live in Spain. Rel subwoofers are made in England, and they are easier to find here then products made in USA. About the price... due to taxes, each Vandersteen is about 2500 US$ (2000 euros) here in Spain. This is a bit more than a Rel Storm III.

The Luna is a bit more expensive. It has only two 8'' cones, instead of three, but it is said to go as deep as 10Hz -3dB !. Neither Rel nor Vandersteen go as deep (at least, in the specs).

My main spakers are, at the moment, not very good. They are just a pair of Kef Q5.

Thanks

Gregm, How could Rel and Vandersteen more authorative in reproducin sub-bass if their cut off frequency is higher?

Thanks

Thank you for your answer. Distortion is, in fact, higher with the same pressule level when power is lower.

About the 10Hz issue... Yesterday I obtained the spectrum of what I thought it was a 'boomy' modern disco CD. It has, in fact, low frequencies, but these compenents are below 30dB than the main boom-boom frequency around 40Hz.

This was a great surprise for me.
