Conclusion: I was looking to simply replace my stock sub in my '02 Tahoe. The shallow Pioneer would not fit so I had to send that speaker back. The new sub rocks. No extra amp. I did not know the stock sub came from the factory already built into a box. The JL dropped in with zero modification. Truly sounds 5 times better than the original. I was worried about the oHms not matching and RMS ratings. Worry not. If I turn it up I can shake a window if I want.
Conclusion: These drivers made a GREAT difference in my setup depending on what you listen to, they really bring out the missing midrange BASS that the 6.5" midrange drivers simply can't pick up. An absolute MUST for a (complete) front stage...
Summary: I'm posting to note that the not so great reviews below seem to be comparing this 8" MIDBASS driver to a SUBWOOFER. It is suited to play about 63 hz to maybe 350 tops - that's where it rolls like a champ. People say the woofer is clipping. Clipping is a term associated with the signal.
Pros: Excellent midbass driver for a 3-way system, NOT a 2-way system.
Cons: Equally as good drivers for less money but usually have a deeper mounting depth or other better/comparable drivers have a larger mounting depth.
Summary: I've had a pair of these in my '07 Trailblazer for almost a year now and have really mixed feelings of them. One blew within a month and had to have it warrantied. I was ticked because I was only feeding them 1/2 their rated power (60-70 watts checked with meter) for break-in. I am a proffesional quality installer and the doors are modified correctly with a solid plate (1") w/sound deadner both mat and spray.
Pros: Sound warm and powerful when the right music is played Look cool, but looks ain't everything
Cons: Clip easily, Over rated power handling (I feed them 95 watts now peak at 90hz 24db cutoff-130 hz 12db cutoff; they should be able to drive at 125 peak) OVERPRICED and causes me to be unconfident of their other equiptment even though the rest of the gear help to produce sonic nirvana
Summary: It sounds good for an 8", but I wish it could handle a higher wattage. The bass is just okay. Its not comparable to even a poor quality 10" or 12" when it comes to bass. But I guess for a free-air setup, its pretty good. It clips easily. I find myself adjusting the subwoofer level on my OEM headunit often so as to not clip the driver. (I listen to a wide variety of music, some with deep bass).
Pros: - The sound from the driver is good. - It's JL Audio
Cons: - Expensive! Not worth the money for a free-air setup. - Bass is lacking, but okay to good for an 8 mid driver. - Clips easily, even following Crutchfield's way to setup a subwoofer.
Conclusion: Excellent Midbass driver. I'm running a 4 way active system, and use these for 80hz - 250hz.. They fill that range superbly. I wouldn't recommend this driver for anyone UNLESS they're running 4 way active, because these speakers are only happy within this small frequency range.
Conclusion: I replaced the 6.5” stock woofers in my 2008 Mustang GT with these to match with the JL 5X7s in the upper door and in the back also a JL 10” sub. These speakers really filled a whole in my sound. I'm driving them with a Sound Ordinance 2X75W amp which does a great job. They perform as advertised and I highly recommend them for any system if you have room in the doors.
Conclusion: I bought this midbass as a bridge between dual 12" subs and a 6.5" mid/hi set of components. These high pass as low as 50Hz while taking 175-watts RMS and will very like take more wattage with a high pass of 60Hz or 70Hz. This is not a midrange speaker. This is a very application specific driver that should be used in 4-way active systems to transition from a very strong bass section to clean midrange section. My results so far have been beyond my expectations.
