Ok so I have had my Dynasty for a little over a week now. I decided to play with it for a while before I posted. Im glad I waited because I have gone through several stages, and impressions with it.
Just a for reference on me:
I have been into this crap since I was 10 yrs old upgrading all the drivers in my parents old speakers. I have also worked at several places from Circuit City, to Tweeter, to Sound and Vision, etc... I have heard most every reputable sub manufacture, from Velodyne's 18's and the JL's to the REL Studio ($9000). Of all the subs I have heard there are MAYBE 5-10 I would own if they were all the same price.
My system is:
Fronts: Dynaudio Contour 3.3's
Center: Dynaudio Contour Center
Rears: Mirage tri-poles.
Sub: (was) Infinity Intermezzo 1.2 (12" CMMD, 850w BASH, aluminum cabinet)
Processor: Harman/Kardon AVR8000
Amp: B&K REF 8274 II
Source: Marantz DV8300
Misc: Strait Wire Rhapsody wires.
Room: Dedicated theater in basement, maybe 20' x 17' x 8', double dry wall, hard wood ceilings, 3 layers of insulation in the ceiling (the pink fluff, the pink foam, and white styrofoam) and thick padded carpet.
Ok back to the review.
I started by installing the Sub where the infinity was, left front corner. I set the volume around 1 o'clock, and the x-over around 70hz, and I ran transformers. The bass was powerfull but very uneven, it seemed that in certain frequencies (lower ones) the sub would bloat, and become over powering, not in the good way. But it was still very impressive most of the time. I played music and I was a little disappointed, It was very heavy on kick drums and no where to be heard in the higher ranges like bass guitar. But again, it was still very impressive. As I moved around the room I was finding that my listening position (middle) was some what of a dead spot, so I did the crawl and found that the rear left corner was best so I moved it back there. I had tried that spot with the infinity but the infinity was somewhat detectable, and being behind me and only 5 ft away, it was annoying. So with the Dynasty behind me, it was detectable and still VERY bloated in the low frequencies. So back up front it went. I then posted in this thread and was reminded to level match.
So I level matched everything and it sounded great. Basically It forced me to try the volume at 8:30 - 9 o'clock. I would have never tried that other wise. The lows were now blending and not bloating. So I tried the back of the room again, and it sounded even better. But still no midbass, or punch at all. I wathced several movies and they all were extreemly impressive, lots of smooth, effortless, realistic, and VERY powerfull impact. (this is at 9 o'clock on the gain)
I still wanted to work on mid bass and figured I was definatly not getting flat respose, and in my quest for midbass I was just over driving the low bass. I decided to break out my RS meter and grab my RABOS charts and CD. I plotted the response of the sub and found a 10db (uncorrected) drop @ 66hz, and 10db drop at 26 hz. So I went back and played the CD at 66hz and played with the delay (which I havent touched in years) and found that the delay was set at 10ft) I moved it down to 5 ft, and gained 10db! @ 66hz. I again gained 10db at 30ft. I then played 26hz and 5 ft was the best option with a 5db gain. I ran the test again and flatened the response by 6 or 7 db!
I grabbed one of the wifes Dave Mathews concert dvd's which had ZERO midbass the first time I watched it. WOW, I had no idea what I was missing! not only was the midbass accurate and smooth, but the kick drum got tighter quicker and lower! I then increased the gain to the 11 o'clock position and the bloat was gone! Just smooth powerful effect. I ran some movies and it was like NOTHING I have ever heard. The best way to describe it is BIG, it just seems to "shift" the room. There are times where only my pant legs moved! Also, the sub is completly undetectable! I decided to put in some classical, and see how it can handle timpanies and pipe organ. Seemless connection between the fronts and the sub. I didnt realize how much of the music was being handled by the sub until I unplugged it. Not only did I lose the visceral impact of the music but I lost the stage. High frequencies tend to be carried by low frequencies and the Dynasty even opened up the strings. I hesitate to say the Dynasty is more musical than the large REL's but i would love to put a stentor, stadium, or studio, in the room and run them. I know one thing for sure the REL's cant stand with Dynasty in the movies.
Overall I am very pleased and i can still see more potential in the sub!
Sorry for the long read, but these were the points I was looking for when I was researching, It was hard to tell if I was reading the impressions of an audiophile, or a car audio bass head.
