    The Truth


    OK, so here is what you're really looking at. Yes its Alpine, and Alpine normally makes really awesome products! but these are the lowest line created by Alpine. It almost seems that the "E" in "E"-series stands for Economy. They do have good volume on them, but they have absolutely zero bass and cant handle the power that come from most factory head units so you get this rattling noise most of the time unless your volume is at a whisper. Really all these speakers are good for is to replace your factory speakers IF they're blown out. I wouldn't recommend these to anyone whos looking for real and true sound or looking to do a complete audio makeover. My advice? get the S or R series; only a couple of dollars more (everywhere else) and they do circles around the E series. p.s. the R series (the ones i have in my honda now)? sound absolutely amazing! so clean

    Great Speakers


    I’ve never bought Alpine speakers before, but these speakers are great. I do not have these hooked up to an amp, just my Pioneer head unit. They are good if you are replacing factory speakers and want better sound quality. They do not have a lot of bass compared to other 6x9 speakers Best Buy sells, but that’s why I bought these. I am installing a subwoofer, so I didn’t want my speakers to have a lot of bass. So for my application they are perfect. If you are looking for bass, look elsewhere. These speakers surprised me with the clarity of the highs and lows, I can crank them up to volume level 55 of 60 before I get any sort of distortion. I highly recommend these speakers if you will be installing a subwoofer as well. Even without the subwoofer, they do sound a lot better than factory speakers

    I swapped out my factory speakers on my car with these. The sound quality: night and day. My old drivers couldn't go past 40% on the volume w/heavy distortion. Plus - they were paper. I just replaced my car about a month ago + my old one had the same stock speakers - I destroyed the ones in my old car. These: nice tough materials, power-wise they can handle 5X+ what my car's stock system can put out (*Sadly, I've got a head unit w/climate + car controls I can't swap out for an aftermarket stereo.) Gave these a run ... bass - these have some serious kick. Nice and clear vocals too - many times better than my car's stock. The music I play sounds WAY different than it did with the factory system I had. So much better, I wish I had picked these up long ago! Not only are these killer, but the auto tech @ Bestbuy set aside the harnesses for me + gave me advice for upgrading my system. Need the parts, they've got them. All around great. Very happy with these.

    Decent purchase


    I have owned the fantastic Alpine SPR-69's in the past and, I must say, they were the very best speaker I have ever owned. Are these SPE's as good? Nope, they are not, but that shouldn't stop you from taking a chance on these. For the money they are a decent purchase. I have mine hooked up to an Alpine MRP-F300 which puts out 50 Watts RMS x 4 channels, and it hits hard. I am not sure why people are complaining about these speakers. Mine are in a 6x9 enclosure and they hit true and loud. If installing in a car door, use some Dynamat, not a baffle. These speakers need power, lots of clean power. I chose this speaker because I have had success with the Alpine brand in the past, and I will continue to trust them in the future. You really do get what you pay for, and I will happily pay a little more for Alpine speakers.

    Good overall

    I purchased these for the back and a set of Polk Db651s's for the front of my 2004 Honda Accord. These Alpines sound good. The highs in these speakers seem to be a bit bright and not well balances which I do not like because I listen to a lot of Salsa and Merengue music which has a lot of trumpet, and guira. These speakers make those instruments sound thin. The polks are more balanced and do a better job. The alpines do have a significant amount of bass and do well even though I only have a HU feeding them 11 watts of RMS power. This is their strength. They sound good without having an amp whereas the Polks are making want to get an amp for them. Overall they are good speakers at a reasonable price but just a bit too bassy for my taste. I would rather leave that to a sub.

    Good speakers, just didn't provided enough bass

    I installed these in my 04 Saab 9-3 with the 13 speaker system. They have good response for harder rock but faster metal they seem to have a hard time keeping up. And compared to the oem 6x9 woofers they don't have as low of a frequency response. Which is my fault and should have looked it up, besides that they have a solid build to them and seem like they should last a long time. Ended up running 6x9 to 6.5 adapters with infinity reference components for my car and it's picky stock amp system. But overall the alpines are good speakers for the price.

    Easy Upgrade. For Economical Buyer

    • My Best Buy® MemberMember

    I bought these to replace my busted factory speakers and I wanted to get something that would be an easy upgrade for a good price. These are good replacements for the casual listener, not for the music enthusiasts. I blast my music and I do that because I love music. These held up well for a month or so but at 2 months they cracked. The mounting is plastic and cracked in 2 places on both speakers. I had the protection plan, it covered that so I'm on my 2nd pair and it sounds like they are cracked again. If you are looking to blast your speakers do not get these unless you put them in an enclosure.

    Could have more bass!


    Works great in my 2002 Jeep Grand Cherokee, it was one of the few that would clear the space of the front door panel speaker grills in my Jeep. They installed easily, and sound great! My factory speakers were blown up front and I needed to find a replacement. These fit the bill! The only thing I'd say is that bass response could be better. I've read that the material that the speaker cone is made out of has an effect on the amount of bass a speaker can produce. All in all a great purchase, though! (:
