when did you get your last 186's if you got them in the last 5 years or so, they are the same as the new ones, the 2 denotes a new chassis, this has no effect on sound..... the specs inherited by pd from the original owners jbl were wrong.... ------------- https://www.elements-audio.com |

Regarding the original question. If you are going to buy drivers for a horn I would look at something else than the new PD186. Btw. some one must own both old and new PD186s and be able to do a comparison? ------------- A proper build subwoofer will be the only thing in a room that is not shaking. |

thx, i will forward it to precision device ;) i think i look for another driver. i liked the pd.186 because it doesn`t need so much amping like other recommended 18" drivers |

and the edges on the magnet plates are rounded now on all mk2's.. ------------- Support the scoop technology, larger mouth plays louder! |

| Are these new drivers no good for the folded horn enclosure (186) |
