Built to provide sound clarity, the SPR-50C can withstand enormous abmounts of power and still provide that quality sound you are looking for.
The new R-Series speakers take a great platform to the next level. Although the R-Series speakers are new for 2017, they actually come from an impressive Alpine lineage – the Type-R speakers.
R-S65  6-1/2
Type-R speakers use Alpine’s patent pending Multi roll HAMR surround, a technology developed for many of Alpine’s legendary subwoofer designs. At higher volume levels, a speaker’s suspension system typically loses control and becomes unstable. Alpine’s HAMR Surround combines both large cone area and long linear cone excursion for deep, powerful bass response.

These speakers replaced my MB Quart Reference speakers. So far, so good. Good sound and nice looking. I'm powering them with a Alpine PDX 4x150 amp. Still need to turn the amp up and possibly set the crossover back to 0. Love the way the tweeters flush mount. Nice design by Alpine. Now for the downsize which has nothing to do with performance. I wish they would have come with full grills that could have been painted to match my interior, should have more mounting options such as spacer rings, etc. I tried to remove the tweeter from flush mount case, but it was glued together so much I was afraid of breaking it. Would like to see a regular insruction/owners manual instead of just putting installation instructions on back of box. (I like to keep all my manuals, not the boxes). Overall very happy. Afterall when it's all said and done, it's the performance that counts, and for the $$, you can't beat these

So far these are the best value for front stage I have found. Paired with 2 channels from my MB Quart 4.80X500 the sound quality is just plain amazing. I'm hitting them with 80 watts RMS per side crossed at 250hz and they are loving it! At first the highs were really harsh but by moving it to -6db in the crossover supplied with these speakers it took all the harshness out and gave beautiful sound to the tweeters. The mids are extemely mellow and smooth just as they should be without a hint of a brassy sound. Anyone looking to see what true quality sound is actually like, this is a fairly inexpensive way to experience it.
