I am in the process of epoxying together the first of 4 lab 12's. I was pricing out and about to order the subwoofers when I saw something interesting. I wanted to get a take on the “lab 12 MKII” vs. the Dayton “Titanic MKIII” subwoofers. They look somewhat equivalent, and I should be able to squeeze them into the cabinet. The Titanic looks like it would give you a lower frequency response, but I am not sure about the spec's. I think it would put some ware on the driver in a lab12 cabinet, limiting how much you could push it. Could someone a bit more knowledgeable take a look and comment accordingly? (both are on parts express website) Thanks.. |

Why? Regular wood glue is more than good enough. About the only area you'd want to consider epoxy or some adhesive with filling capacity is the baffle area with the compound mitered pieces that form the initial part of the flare-and only if you're woodworking skills didn't produce a tight fitting set of pieces. So much extra work and mess for nothing. Best regards, John |

PL Premium is a good choice as it is super strong-fills gaps-and has a slight expanding characteristic. More expensive than regular wood glue-but MUCH less expensive and less hassle and much easier to apply than epoxy. |

Jason If you want a drop-in alternate, look at the Quattro QT305-4. The Titanic's Qms is too low. Per Tom Danley you need for the Qms to be >9. The Vas and Qes are pretty close. Xmax is respectable at 10MM. About $40 less, stamped frame and lower power handling are the trade offs for the lower cost. HTH Jeff Robinson |
