Posted by Donnie S on Oct 20, 2025 For the price, this is a pretty stellar set. The 6.5 midbass driver is pretty much perfect from 80hz and up. It can be crossed lower but you will reach mechanical limits quicker. Excellent depth and tonal balance on the driver. The 3” midrange is pretty neutral and very natural sounding. The only thing I’d change is ditching the spade terminals and go with screw type ones like on the crossovers. Push terminals would be too bulky obviously. The tweeter is a weee bit bright, this is usually the case for a metal dome. It can be very aggressive for some and it would be very nice if there was a choice for a silk dome option. The tweeter can be Tamed with some Eqing but still has a sharper sound to it. Sound is purely subjective and many may prefer this, but there are many that would prefer a silk dome offering. A set of grills for the 6.5” and 3” would make this an epic deal! Overall the set will not disappoint 5 But there, you'll not regret it Posted by I have 2 sets of these and they're incredibe on Jun 17, 2025 I have 2 sets of these. One une w bookshelves and one in a center channel (overkill, I know) and they're phenomenal. My car has Zapco amps, W7 subs, diamond d9 speakers, yada and yada. There (like most of this insane mans stuff) is waaaay underpriced. BUY THESE!!!!! 5 Loud and Clear Posted by Jlarsen on May 04, 2025 I got this 3 way paired with the hexavone 6.5 and this system on the jp234 just scream, once you get your amp set right and adjust the EQ these things are loud and super clear. 5 Amazing Trio!!! Posted by Sergio Morales on Oct 26, 2024 I have one set installed and running and they sound Wonderful and still going strong. This new set is for the rear fill, I know, it's just a little excessive, but hey, why not.... 4 3 way componets Posted by Rick Pena on Sep 20, 2024 Great product for the price. I'm running active with the D4S DSP. Only reason for 4 stars is i think the woofers and midrange should come with with some screens. That's the only down fall. 5 JFX653S Posted by Donnie Bryans on Apr 24, 2024 I used these to replace the front speakers . Absolutely Incredible how good they sound . 5 Powerful mid bass Posted by Chad Perry on Sep 11, 2023 What a great component set at any price. But at 400 bucks wow!! The mid bass is tight and accurate, the mid range is clear and works great on axis and the tweeter is crisp and bright enough without being harsh or too sharp. I really love these components and would highly recommend these as long as you are in the 1000 or less budget. 5 jfx653s Posted by Dug Thompson on Jun 21, 2023 Absolutely incredible!! i had them mounted in a custom cabinet for home use. Theyre so smooth, detailed and accurate!! Buy these!! View All Close
