Yes. Sometimes subs benefit from being broken in, but your problems will likely be resolved by learning how to better setup and configure your system. The S10.3 is a good sub, and plenty of people have reported getting it to work wonderfully with their setup in the owners thread for these Pioneers--as well as with other (and more expensive) 5.0 speaker sets of other brands. Take a look at batpig's Denon and Audyssey guides
as they can help. Configuring subwoofers and Audyssey, as well as getting to know Denon receivers, can be tricky at first.
Are you using Audyssey with stereo mode? Since Audyssey EQs the sub, then if it's turned off, it might not sound as good.
Also, what source material are you playing on your iPhone? Crappy mp3s or other poor quality content could contribute to your problem.
Setting your speakers to "full size" will disable the ability to set a crossover and send all the bass to the front speakers which can not produce the lower frequencies that the sub can. Try leaving them on small and using 60 or 80hz.
Also, make certain that when you ran Audyssey that you set the gain (volume) on the sub such that Audyssey determines a channel level close to 0db. This best optimizes the sensitivity of the sub amp for the input from the receiver. If Audyssey determined a channel level much lower than that, turn the gain on the sub down and rerun Audyssey.
After reading batpig's Denon setup advice, in particular the Audyssey setup guide I realized that I had been doing it wrong the entire time. I eventually positioned the mic in all 6 positions instead of one, adjusted the sub's volume to get as close to the 0db volume adjustment on the Audyssey read as possible, set the front and center to small as intended, moved my couch more forward as shown on the picture, tilted the front and rear speakers towards the middle listening position, moved the center more out of the center console as suggested, which all made a significant impact on the sound quality and the blending, balance, and for the lack of another word the "matching" of the entire system overall.
So far I've also tested out dynamic volume setting and found it to be EXTREMELY helpful in my situation with the complaining neighbors especially with the "midnight" setting. But even with the daytime setting it brings out the vocals and the minute details more than you would have heard with the setting off. Playing 5.1 source from the cable TV was impeccable, as indicated by watching the Olympics closing ceremony yesterday. 5.1 source from Netflix was very good too, from what I've seen by watching Lost and Breaking Bad episodes. I have yet to test out the iPhone connection, which was the source of the problem to began with, but am convinced that it'll improve if not resolve.
BTW, I was playing mp3 audio files that had 320bitrate when I noticed the boominess of the bass coming from the sub. I doubt it's the files themselves because when played on the PC or using my Klipsch iFi speakers they were flawless. Perhaps it's the connection from iPhone to the Denon receiver, that it automatically set itself on a bass heavy EQ setting or something to accentuate the bass? I'm not sure but will test it out when I'm postcall from work
in the end though, I doubt that I'll be returning the sub, but will test different placements of it to improve sound quality. One thing I did note upon installing it, the sub's exterior paint was a perfect complement to the Pioneers as it has almost the same patterns and texture.
