Review: They have a very large sound and you can hear the clarity in the music with them so well! - I put them in my 4 runner 2004 at the top of the doors they had a 3 inch tweeter . I had to make the hole in the bracket that held them in the door itself a little bigger . But they went in fine as far as the rest of the clearance . The door panel itself had to have some small trimming . It was just soft plastic and it didn’t hurt the integrity or comprises the overall appearance on the outside side . Now the sound quility is unbelievable. It was a big difference like watching a 13 inch black and white tv screen to moving up to a plasma flat screen in high definition ! Because before there was just a tweeter now there’s a mid-to high range woofer that goes down to 52hz . Then with a more complex an advanced tweeter that plays up in to the 33k hertz . You can really hear how dynamic it really is . I have hertz audio 8 inch sv200L SPL speakers at the bottom of my doors . Then alpine 1.25 tweeters custom molded in to the top of my A-pillars . Setting in the front two seats it’s the upmost sound quality one could get . That tells you how good these little pioneers are . The two other names I mentioned are top quality companies. Like alpine comes in Lamborghini, Ferrari, and BMW just to name a few . Hertz audio SPL speakers are for competition. I’ve always been a pioneer fan and these little 3.5’s are out of this world . Pioneer has stepped up its game and for less than $80.00 you can not find any that size for any less money an you have to pay 4-6 x that much for any thing close. Morel and hertz wants $1000.00 plus for a set of tweeters that wil out do these ones . You can’t beat these for the price and the quality. An the small size you can just about put them any were if your customizing or modifying a stock location. They really impressed every one who has listen to my system . They all say they can hear more detail in the music an they seem to fill in what was missing between my really highs and my mid to low range. I looked high and low for a set of tweeters and had no luck for the amout of money I was willing to spend . I was ready to go $200.00 . Then I seen these and checking every thing from $450.00 an down . Thers no other that can get you that 33K hertz on the top end . I seen some that went 22K&28K but they were close to half a G. Now I might spend that much on 2 - 8 inch SPL woofers . Even a buck fity on some alpine tweeters. These pioneers sound like they could be a set of $500.00-$1000.00 dollar speakers . And they handle way more power than any others under $500.00 . 100Watts (rms) up to 450Watts of power . That’s insane for a 3.5 inch tri-axle speaker. I put around 100-225 on each of them and they are extremely loud. You just wouldn’t believe it . I’ve had them now for almost a year an they never have disappointed me if they last 2-4 years I can say I definitely got my moneys worth . I highly recommend them you won’t be disappointed and I think if every th8ng is done correctly and they don’t get any weather damage were you instail them . You’ll love them for the sound and power handling. You’ll find you need no were ne’er 450Watts to hear how loud they can be . I’d say a really nice head unit that had 50Watts x 4 (200Watts) tottal . Would make them jam just fine . I thank desertcart for being able to get them . There was no were else that had or could get them they were on back order and they cost more money like $100.00 and even higher. I found them through Google . But all the places were out of stock then I seen desertcart had them I ordered them an within 5 days I got them . I think it said a week to 10 days but they came early . Soon as I got them i installed them . I waited this long so I could give a review that would let every one know how much time I’ve jammed them hard at half power and how good they sound an still do . So you would know with what I’m telling is from time experience how great these are for your money even if they cost 3x as much as I paid I would still pay upwards of $250.00 for them because there just that dang good. Also thanks to Pioneer I’ve been a fan for over 42 years now ! An I’ll never get to old to not be to loud . They say they can hear me for over a mile and half before I get there ! I should get y db’s checked to see how loud I really am ! I have them and the 8’s running off a JL audio 400Watt amp . With a 2004 alpine CD head unit . Very nice very clean and extreamly loud . One of the best I ever built thanks to these PioneersTS-A879’s and desertcart’s help getting them ! I would take a picture but you can’t see them through the screen in the door pannle . Recording them for you to hear would do no justice. If you buy them you’ll see or rather hear what I’m telling you . Loud in southern 304 Wes by GOD Virginia ! Yaw come an hear me if you can !
Review: Great replacement dash speakers for my 2nd Gen Firebird - Very happy with their sound in my 1981 Pontiac Firebird Trans Am. Small speakers, so I wasn't expecting much low frequency output. Nice clarity and volume, though. These in the dash pair well with my 6x9 speakers in the rear package tray to deliver audio from my modern Custom Autosound USA 850 stereo. These are a great replacement for the ancient Concord Comp 300 speakers Pontiac installed, which long ago stopped working and had mostly rotted away after 44 years. I had to trim one of the plastic mount points so they would fit in the OE steel brackets that hold them in my cowl panel. The OE speaker grills easily fit over them.
