    volume, please for 250Ti

    Has anybody measured / know the internal volume of the 250Ti cabinet ? I need to retune a set of boxes for the clones I am making.

    The boxes are 3.2ft3 ( originally 4315B's ) and if anybody has suggestions on tuning, the currently installed single PVC port is 3" dia and can be lengthened as required.

    Also, of potential interest, this:

    I've kinda settled on 1.1 - 1.3 kHz with LE14s and small horns....

    Try hear as well. Remember to subtract the sub-chamber volumes for the 108H and 104H

    Port in a storm

    Thanks guys!

    I spent all of 10 minutes poking around but didn't see the tech spec sheet that giskard had posted.

    Well it looks like the 3.2ft is going to be a little small unless I play games bumping out the back.

    But I have to make room for the monster caps on the CC crossover so maybe that's a good idea...

    My 104's came from 104h-1 frames and Ebayed cone kits. One of which was bad so a newer kit was ordered from JBL. The 108's were 2118's that had the frames painted black and new 108 kits installed from JBL. Both cone kit's were available from JBL a couple of months ago. They may still be if you want to go this route.

    diggin' an a scroungin'

    The 044Ti's were removed from 18Ti's from a music store...50 bucks.

    The 104H's were rebuilt from 104H-1's with new kits.

    The 108H's showed up on ebay with new cones, 100/pr. BIN..

    LE14H-1's were built using 2225 mags on a pair of 14" frames from a recone shop's graveyard.

    So far, so cheap. I have at least 5 major speaker building projects that have been on hold since I relocated the woodshop one year ago. I need to get some of these *done* and then decide what to keep and where.

    I tell the wife the hobby / sickness COULD of been old cars in the yard....

    Sorry to hijack thread, this is exciting news to me
