What is being described here is the Mini DSP ...

Handy little unit, run your RC then add it in and make changes at will. Add a highpass filter for the low bass to protect the driver. Unlimited manipulation along with REW.

Mojo and I are grazers, I am also a tinkerer, I love to tweak things. What I find is that each music source is different, there are subtle changes and sometimes a higher crossover is perfect and other times the lower crossover point works more effectively.

What I like about the EP 500 is that it's so linear and smooth, I can dial in exactly what I would like to hear with slight alterations of the crossover settings, I would not like Ian to remove any of the control functions at all. I like more, not less. However what would be cool is if there was an out board controller replicating the same functions as at the back panel so that we could have quick and easy access to making changes remotely.

My idea of having some other DSP configurations to select at will would perhaps appeal to those guys who want chest beating with their HT set ups. I am not into that, I like smooth music. If I want more dynamic power, I'd add in more subs, which I plan on; the multiplication factor is something to work with....

Ian would give you all the switches and dials that are on the amp currently plus a whole lot more, oh Chief Grazer. You could access the sub's control console from your phone over wifi.

OK Mojo, I am warming up to the idea of a phone app via wifi to play with sub adjustments on the fly.

So Ian is perhaps considering some of our brainstorming here; it certainly is a nice way to kick around tweaks.

As it is, I really like the new amp control with the addition of the variable phasing; I found it was useful in my set up. However, I didn't even look to see if the USB port was on it or not. Did you say that your new 800 didn't have the USB port?

Nope...no USB port; not that it matters. The variable phasing is very useful for me too. The app would be a killer!

Have you found the subsonic filter useful when using the turntable?

Actually, I don't need the sub-sonic filter with my Turntable as I modified 4 of the SVS Iso-feet for the subs to mount in place of the useless conical point feet that come with the TT. The medium durometer rubber feet with the 75 pound turntable totally isolates the feedback, I have virtually none. But keep in mind that I machined out the center hole in the steel cup of the Iso-feet to accept a shouldered rubber grommet in which I inserted a stainless machine screw which compresses on the grommet and I also cut 1/4 inch neoprene circles to sandwich between the steel cups and TT base. There is no direct contact of metal to the TT base, it's all isolated with rubber.

" Though I wonder about the ones that manage to have more continuous output than the wall socket they use can supply."

Ian, I just purchased 10 of the competitions subs with more output power ratings than what they consume from the outlet; I finally realized that these other companies have invented perpetual power devices and I plan on powering the entire house with more power than I purchase from the Grid!

Slim, ideally you want 2 subs to even out the bass. The Minidsp allows you to correct for anomallies in your bass . My last house had a huge suckout at 70hz as measured with a calibrated mic and REW, which happens to be right in the range where it hits your feelers. I managed to move subs around a bit and equalize and time align the subs with the Minidsp to help mitigate the issue. I have been lazy this past year and havent done much in the new theater but it is much more forgiving and my subs are both up front and corner loaded. Perhaps one day i will build my MBM's and do some measureing. I am no guru but i share what experience and maybe someone will take interest as well and dive down the bass rabbit hole like Trevor (serentitynow). Bass can sound good and be wrong, we all have our preferences and the room has a huge impact on the music we hear. Enjoy your adventure.

May I ask what the mini-DSP device is?
