Thoughts from the customer?
"First off, I'd like to thank Trey for job well done. He quoted me 2 1/2 weeks time door to door and it was only 2 weeks and that's 2,500 miles away! What an improvement these crossovers make for music. More detailed tighter bass and cleaner sound. Almost all day Saturday I listened to my music from pop rock, jazz and classical. Putting my system in 5 channel stereo was incredible. Then switching it to Pure Audio so I get full range and just the front RtiA7's is a BIG improvement. The tighter bass and detailed sound coming from just running the front's is a big improvement! I haven't had time to pop in some moves. I've run the YPAO but I want to dial it in with my SPL meter before I pop in my Master and Commander, Avatar and what not to test it out! Again I can not thank Trey enough for the quality and good service I got on these crossovers! Now the rabbit hole gets deeper... gotta upgrade my sub, get a NAS for my lossless files...maybe an amp!!! " - George (Polk Audio RTiA7/CSiA6 Fortress Level Mods)

"I have received the crossovers and installed them right away. The quality of the work you did Trey is outstanding, it's too bad those x-overs are inside the speaker and not outside. Also I have never received the package that would be that well packed.
I am in the process of burning the crossovers in, but I can already hear a difference in sound. I don't know how to describe it but my it is much more detailed, specially in a mid area. They also sound cleaner. Thanks so much for the awesome communication you were able to provide during the process. I just realised we have exchanged about 70 emails all together. That's more then I posted comments on this forum :-)." - Chris (Polk Audio RTiA7/CSiA6 Fortress Level Mods)

 

So I have the Rti A7 crossovers back from Trey / Vr3 with the Fortress modifications done the workmanship is first rate; Excellent work Trey! I when home and installed then right away I'm quite fortunate to have a job that is close to home and flexible enough to allow me to do this! Well I wasn't quite sure what to expect from this modification I knew that burn in time was required so I threw on some Joe Crocker just for a quick listen it was a very nice and pleasantly smooth sounding. That was on Monday on Tuesday I had time to listen for over an hour same smooth absolutely no harshness at all. I should point out that I have then on since I installed just at low volumes playing some SB radio station to help with the burn in. Before the mod I would get a little tried I guess the word is fatigued after listening for a long time; I know an hour is not a long time but it don't appear I will have that issue anymore. So far I'm quite impressed with the results and as the burn in progresses I'm looking forward to these improving and sounding better although if they don't change I'm all right with then as they are as they sound great. Thanks Trey awesome dealing with you. Cheers Roger - Roger (Polk Audio RTiA7 Fortress Level Mods)


"Dude they sound incredible!!! I've only listened to music, some of my lossless files (flac). How can I explain it...it's just richer, deeper/cleaner bass and more detailed. I haven't done any movies (bluray's) yet but that's next. My ears are just worn out from all the music today! :p I just got a cop[y of David Gilmour Live at The Royal Hall bluray so that's tomorrow. :)
Thanks for a great job and when I'm done dialing everything I'll post a review on the forum." – George (RTiA7 Fortress Modification)


"First of all I would like to point out that Trey is great to deal with and the quality of workmanship is first rate. And second I?m not any kind of Audio expert not even close what I know I learned mostly on this site and some haphazard research on the net. So it?s been a few months now since I got the a7?s modded and I love the sound, no harshness, no fatigue, just great sound. My humble gear for listening to two channel consists of HK AVR 3600, Parasound 1500a Amp, Mitt interconnect cables, Luminous Audio Synchestra Signature Speaker Cables and Source is the world?s greatest invention Squeeze Box touch; music ripped apple lossless. Before I had these crossovers modded there was times that I couldn?t listen for more than a couple of hours at a time as they tended to be kind of shrill on some music playback at moderate levels, nothing against these speakers but is common knowledge and been stated on this forum many times great speakers( I do believe these were designed for HT and they excel in that format) but playing then moderate to loud with certain types of music can be a bit taxing on the ears. I didn?t think that modded crossovers would make the speakers capable playing such a wide range of music and still sound good to my ears. And now it?s a pleasure even after mouths of listening it brings a smile to my face whether it the Kids playing pop or Indy music, or me playing hard rock, classical, jazz or the blues everything sounds fantastic. Now what I compared then too is a friend?s Kef Q9 with a newer Parasound and another friends set of 2011 Martin Logan?s run off a new Marantz AVR playing the same tunes on CD. Not apples to apples of course but both guys have fine equipment. And I have to say I would take my modded a7s over theirs any time. I?m truly impressed with the improvements in overall sound. Cheers" - Roger (RTiA7 Fortress Edition)
