Pioneer TS-D1720C

These are very clear and loud! These are a must get. and at 120 shipped? Awesome! I have these hooked up to a 4 channel eclipse EA3422 amp and the rear channel bridged to a pioneer champion series PRO 12.. and no back speakers. I just wanted a good front stage. I def. recommend these speakers to anyone who wants to hear there music as the artist intended it to sound. i have heard CDT and boston pro components befor and these sounds just as good as they do. but dont buy them unless you plan on powering them with there full rms power. outherwise you could be wasting your time. a clean amp that pushes atleast 45-75 watts RMS is a must

I bought these components since they came out and they are still among the best I've ever heard. The mids and highs are terrific and they can handle bass really well. A factory or aftermarket radio won't do this component justice so an amp is a must if you truly want to hear what these speakers can do.

These were installed into a 2001 Isuzu Rodeo and only powered form an Alpine head unit, so I can't attest to their overall sound quality if driven from an amp..

Overall the install was fairly straight forward (had to modify mounting locations, but nothing a Dremel and some time couldn't fix). The adapter rings are a nice touch if you have the depth to use them.

Compared to the original factory component setup these are vastly better. Like many other have said the tweeter can be a bit bright, and my wife and I don't like ear bleeding highs, so it was wired at the -3db setup. The bass if good, not overly pronounced, sometimes lacking on the low, low end, but given what I'm working with and no amp it sounds pretty good.

The midrange can be a bit more deceiving. And this might just completely be the issue of no amp, so take this part with a complete grain of salt. Compared to a similar head unit driving a set of 6x8 3 way Pioneers with a Sony amp I had in a previous vehicle these seem a bit lacking. It is hard to describe. The transition is very smooth between the woofer and tweeter, but it's almost like it lacks clarity. Again miles better than the factory setup, could just be an amp thing.

Over all very good component setup for the price. I would purchase again.

I just put these speakers in the doors of my MR2, they are being powered by a Crunch 5-channel amp and sound amazing!! They take a lot of RMS and as long as the bass isn't too much they sounds really clean. The crossover is large but also adjustable. Has an extra wire that lowers the volume of the tweeters. The woofers are pretty big and heavy but only because these things are built well.

This pioneer ts-D172C sound awesome built in crossover super great i have them in my 2006 Lincoln Navigator.
