Best subwoofer for a Wilson Puppy

Neil:
We used the internal software and it would not go below 40 Hz. It was a DD-15. I read the manual and the owner also tried everything and 40 Hz was the lowest point. Had I been able to set it around 25 to 28 Hz it probably would have worked, but as it stood we had just too much energy around 35 Hz even at the lowest output settings. Is there some special way to allow the low pass to go lower, or did we have a brand new sub with outdated software from the dealer? I would very much like to know.

Rives:
There isn't anything special that needs to be done to have the sub crossover below 40Hz. I'm not quite sure what was the problem in your situation. This isn't an issue that was addressed by a software update. It shouldn't have been a problem. That's strange.

I also have had no problem setting my DD15 to low-pass below 40hz

Perhaps I misunderstand, but you may be missing the point. I think that Rives is saying that regardless of the external or internal control setting, his test instruments showed that the Velodyne was not crossing over below 40 hz. This could have been a problem with that particular unit or a problem in general. The only way to know for sure is with appropriate test equipment. Given that Rives is not in the business of selling a particular brand of sub, their main interest must be in making the customer happy.

Well this is interesting information. The Wilson Sub in Europe is 14500 euro (18000 US$). So I guess I can not afford it. In stead I am willing to try the Velodyne. I guess if you adjust it manually it will be possible to set it at 30hz and if you use the software you will not be possible to do so. With this price of the Watch Dog you can imagine only a few are sold in Europe. Second hand impossible to find. In America the voltage is different so if I import one from America I need to pay VAT (19%), then shipment and modification to 230V. This is going to be as costly as bying one here. How much definition in the bass do you hear at 20-30hz. It is more feeling than hearing. The speed is slow at this frequency. So I guess any good sub that does not add upper harmanics (and then destroy the good quality of the WP7) will do here.
