lvisneau, when you did your test w/out turbo, where you in max output or extension? It looks like max output, to compare apples to apples, if it was max output could you run your sub in max extension without turbo?

Thanks

The freq response should be the same in max extension mode whether you use the turbo or not. But with turbo, it will play louder without port noise.

Looks like a laundry machine.

Well, port noise can occur at somewhat higher frequencies as well. I would say the turbo helps at 18hz and below.

I expect to keep my Turbos. Adding a foot of additional dual 4 inch ports makes a difference. Sometimes I blow the port plugs out of my 'HOs, when I don't have the Turbos attached.

All the Best

The turbos are only for max extension mode. You can do damage to the amp if the settings are incorrect from what I hear. I've since reconsidered and I'm keeping my turbos. All I needed was to do a little more tweaking with room placement. I don't feel i'm losing enough above 20hz for me not to use the turbo. It doesn't hurt having dual subs either.

Using the Turbo in max output mode would actually be ok. It will give you performance somewhere in between the normal max extension mode and max output.

The only time where you can damage the sub is if you put it in max extension mode with both ports open and no turbo.

What movies were you testing with? Most movies have the heavy bass in the 20hz and higher range. There are some movies where there are some sub 20hz effects and it's definately noticeable at my house between max extension and max output modes: Casino Royale, Pulse, Flight of the Phoenix, Pearl Harbor, Jurassic Park 3, and WOTW to name a few. It all comes down to personal preference though.

Ya I have the same experience, whenever I compare movies or music there's noticeably more impact without the turbo applied, but as mentioned above some movies benefit from the turbo which is one of the reasons I bought a 2nd sub and kept the turbo.
