Bolt down ring is done for the next production run that will be on it's way to me shortly. It sits on top of the spider insider of the top lip on the frame and bolts in from the back - this way the cone can't come down and smack the bolt heads.

that looks awesome!! and tuff!!

so do us with the that order the first ones need to make any modifications or should be alright??

If you are running higher than 400-watts RMS you should consider adding epoxy like my tutorial shows :

Is this ring something I can do when I re cone my 4?

so if im running three wired up to 1.33 ohms powered by a sae1200

should i need to do this

. dont want to ruin anything by making a mess with the epoxy or damage them

o yeah and box will be around 1.3 to 1.5 cubic feet before displacement will know exacty once i get my braces done

You will be fine. It's quite uncommon for the spiders to come off anyway -- and you are well within the box size and power range.

The bolt down is primarily for SPL competitors (like me) who burp 1000-2000+ watts on them.

when are these expected to arrive?

Early to mid July.

will they be the same price? and do we order directly from u?

would u think 2 of these would be better or 2 truebass ultras? they would be in a box a lil over 2 cubes tuned to 31hz powered by a SAZ 1500 SA-8 @ 1ohm and the trubass @ 2ohms. thanks jacob

I have no specs on the TB ultra at all to go by... so I have no clue.

Pricing is still the same on these (not pre-order pricing) -- $129 each.
