What are your opinions of DSP's for speakers

If you have a good room without too much furniture in the way of the sound then going without DPS is what I would do. I do this in my Livingroom which has 25 foor ceiling and the first reflection is far away on both sides. I also have 0 furniture in the Livingroom, just the speakers. 

With regards, to Danny. I am referring to his new floor standing speakers, Not headphones.

Magnepans also are not that difficult with respect to first reflections.

I will use subs or a sub crossover that uses DSP but not on the speakers.   Don't feel there is a need to in my rooms. 

What is DSP?

There's a lot more that goes into the use of DSP than room and bass correction.   They also serve to give designers better and more powerful tools for crossover design and phase correction. 

If you ask, do I use DSP for bass correction?  Yes, absolutely. Even better if you can do it before your DAC such as with Roon. 

I’m a bit mixed on this.  As a purist I don’t want any extra processing going on in my system and would prefer using room treatments to mitigate those issues.  But many years ago I got to hear a six-figure system in a dedicated and treated room using the TacT 2.0 preamp utilizing their room correction (now employed in Lyngdorf products) and the results were fairly astonishing.  The system sounded very good in bypass mode without room correction, but it was undeniable with correction the sound was significantly better across the board.  I heard something very similar at a TacT demo at a show several months later so this wasn’t just a one-off impression.  Kal Rubinson did a review of the same unit in Stereophile around the same time, and what he found in his treated room was pretty spot on with what I heard and summarized it well in the review when he said “And even though I have concerns about the absolute transparency of the TacT’s A/D performance, those were more than outweighed by the advantages of room correction.”  Those echo my experiences exactly, and here’s the review where his listening impressions  start on page 3 if you wanna skip all the setup hoopla.

So initially as a purist I was very resistant to using any DSP in my 2-channel system, but knowing what it can potentially do I will definitely give it a shot at some point just to see because if/when it works it really works to the point where you don’t wanna listen without it.  So I’d say don’t knock it til you at least try it.  Just my experience FWIW.
