Re: SVS PB13-Ultra 10 Hz tune *new*

We have been testing these (actually two of them) for a couple of months now here in Norway. Quite outstanding output and also superb integration for not only movies but also music.

Definitely a subwoofer for those who wants "it all"... :yay:

When will you release your test of the PC-13 Ultra (cylinder/tube)...?

Keep up the good work, Ilkka!

Re: SVS PB13-Ultra 10 Hz tune *new*

The Ultra in 10hz tune is looking better all the time. Those are some very clean clear numbers it posted. I will say that it's amazingly great in 10hz tune up until you get to start pushing port noise which for me happens about 4-5 db louder than I listen, so it's all good.

Thanks to Ilkka and his friends for all this good work.:clap:

I haven't tested it yet so I can't release it yet. :) Hopefully I will be able to test it next spring.

I have to say that I don't recommend using the 10 Hz tune unless one uses only low to medium listening levels (especially music is fine). I don't believe one can clearly notice the added extension over the 15 Hz tune, but the higher deep bass distortion and port noise will be perceived pretty easily. It is true that the 10 Hz and sealed settings shape the frequency response by taking out some of the energy around 15-30 Hz and moving it towards the lower frequencies. That can make the bass sound less 'heavy' and less 'boomy' in many typical rooms. So if that is the case with you, the 10 Hz tune is justified. Just remember that you are deliberately hampering down the performance at higher frequencies by doing this.
