What are your opinions of DSP's for speakers

No matter how good your system is it still has to operate in your room.  It's not surprising that the room's dimensions and surfaces can dramatically affect how a speaker sounds.  Most people do not have the luxury or money to build an acoustically perfect room from scratch, and others often cannot even install all the room treatments needed to maximize sound quality.  The latter is especially true if the room is used for multiple purposes.  In those situations, DSP can be an invaluable aid for fixing room nodes.  I know in my situation DSP room correction made a great improvement in my listening experience.  But, as with any other decision regarding audio equipment, each user need to try and experiment for themselves and then go with what works for them.

@willywonka I used DSP implemented on Convolution filters running on ROON (so a computer). The DSP is processed before the bits hit the DAC.

In a difficult room DSP can make a speaker work where all other physical approaches are not as good. I had encountered this when I tried to put a Thiel CS3.7 speakers in a small room. Without DSP and using only acoustic treatment I got about 60% of the sound possible with the 3.7. Using the DSP specifically made for my seating position, my room, my speakers I got a sound that was about 80% as good as the 3.7 was capable. I could hear what 100% of the 3.7 was capable of in my larger Livingroom,

I had my Convolution filters done remotely by a professional audio engineer. He also did the filters for the RAAL SR1a that you owned. I stopped using the RAAL filters when I got the VM-1a. I believe you owned both.

BTW - if you are looking for speakers give Danny a call in Ventura. He has designed some incredible speakers.  He should be very close to selling them now. He likes them better than my speakers which he was raving about after a listening session. I heard his new speaker in prototype form, and it was a killer sound. Very unique.

BTW - I recently got the Townsend Podiums (floor platforms) for my speakers. I can really hear a difference with them. Recommended.

@yyzsantabarbara I actually talked to Danny a few days ago at AXPONA. I'm not really listening to my headphones at all. I sold my VM-1a but still have my headphones. I also used convolution filters with my RAAL headphones. They were also custom made for the headphones by Accurate Sound. The purposed of my question was really just to determine what people were thinking about DSP's. I have pretty good room acoustics and do have room treatment. Really not sure what direction I will go with speakers. I'm all over the place now but really like my Planers. I'm thinking OB, Planers or electrostatics would be best for me. These types of speakers also have less interaction with side walls than boxed speakers. Love huge soundstages, transparency, and crystal-clear sound. I rarely listen to anything above 90db. Thanks for the input. 

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.
