What are your opinions of DSP's for speakers

@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.

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.
