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 bought these to replace the Bose paper speakers in my 2009 Mazdaspeed3. I have a been using Pioneer hardware for over a decade and knew the D series components would be a solid investment. This is the first time I've been slightly disappointed.



The 6.5" woofers have been great. Plenty of punch and accuracy down to 50-60 hz. The tweeters however leave a little to be desired. There is a nasty bright spot around 3.5 khz. In other words, female voices are "ear-piercing" at moderate level. I'm awaiting delivery of a new HU and will try to adjust tuning through the on-board EQ.



What I like most about this set is that Pioneer includes a decent set of lightweight baffle plates for those of us with 6x8 enclosures. Allowed me to drop in the 6.5's with no modification. With a bit of deadening, these handle the cone movement just fine. Tweeter pods a bit bulky but not horrible. Once assembled, they take some finesse to pull back apart (should you want to adjust your listening position).



For $110, you can't really go wrong with the Pioneers. But be prepared to do some serious tuning. In the future I might spend the extra $50-60 to go JBL P660C, Focal A 165 or Polk MM6501.

So, I installed these speakers in my bosses Chevrolet truck after he asked me to make his truck sound more like my car. He has them powered simply by the after market headunit I installed last year and he loves them. I too, have these in my car powered by a 60x4 modest amp and like them. Easy to install, and the speakers sound incredible regardless of the power source.
