The Arendals are known to have wide dynamic range, so yes, maybe a little better at high volumes but how long will your hearing last at those levels.
Good point. I watched Mad Max: Fury Road with the volume cranked up on the first day I set them up, and it was awesome.
Besides the R700 towers, the rest of my 5.1 are still my old Paradigm Monitors with an SVS PB-1000, and it was already an improvement. I've also found no issues with mixing different speaker types or brands.
Compared to my Monitor 7 towers, the Polks look like refrigerators.
To me, the R700 sounds more forward in the highs and the upper mids compared to the Paradigms. It could be that I'm just used to the Paradigms being more laid back, but it can be too much with some music when the volume gets really high.
I think your on the right track of making sure to compare the Arendals at home before you let go of your Polks. You may find that any improvements or the extra headroom they provide isn't enough to justify you giving up your Polk Reserve but if so you found your end game level speakers. Sounds like a win win to me
Yeah there's always that "what if". Maybe the increased dynamics will be worth it. I do like the value that the Polks offer though, and I'm happy with the sound so far. But I get a free 60 day trial, so what have I got to lose.
I'm mainly looking for more impact with movies, so I'll be looking to upgrade my sub to duals next.
Oh, and I've seen on another forum that Polk runs big discounts a couple times a year. I missed out on it this time, but right before Christmas they had some Legend series speakers for 40% off. You could score a pair of L600 towers for $1700, and the L400 was going for right around $1000.
