only thing to take care of with the amp,,must drive 3 ohm (3ohm impedance about 120hz with passive filter)
i must say ,it is my opinion about hypex or not,,other will maybe say the opposite ,,we all listen different
Thanks for replying.

My apologies for not being very clear on my questions.

Since you have a 500wpc amp you have the ability to run all drivers, through the crossovers, at one time. Since I only have 100wpc amps I am good for the mid/highs and relying on the Hypex for the 18Ē.

In Troels Fusion 3 he uses a 2 channel Hypex. One channel for the woofer running without a passive crossover, and one channel for the mid/high through a passive crossover.

I was wondering if maybe an advantage/option to run the Hypex to the 18Ē through the passive crossover?

I understand that you havenít tried it, but I wonder what it might sound like?

no ,you was clear with the question ,,i believe that if the amp is stabil in lower ohm then 100w is enough to drive the speaker...just wait and try

you must try both way with the hypex....then you can use what is best with you..but give the speaker some time to burn in

Thanks, I plan on trying both ways.

How much time for burn in does this speaker take?

Thanks for the info, hope they are ďlistenableĒ in just a few hours?

Going through the wet sand phase now. About 7 hours for the first one, twin tomorrow. First one turned out perfect, no sand through and no defects. A light touch with 800 grit to knock down any dust, then down to about 95% flat with 1000 grit, then to 100% flat with 2000 grit to get final 5% and 1000 grit sand marks.

They look real ugly at this phase.

But nice to have them home and working on them on the back porch and listening to music while I toil away is less sucky.

Polishing up next

After 2 days of wet sanding, and then 2 days to polish, Iím finally able to start assembly.

It was late, but took a quick couple pics of what the crossovers look like in their new home and the back panels I designed and had made.

I hope to be able to spend the day on them tomorrow and maybe fire them up!

Default They are playing!

Currently Iím 90% there. The main cabinet, drivers, finishing, crossover, and plate amps are basically complete and playing.

I have yet to install the casters and related skirt, order trim rings for the mid and bass drivers, complete the assembly of the super tweeter and related.

Sounds pretty good out of the box, so to speak. Since there is a 100 hour break in needed Iím not even trying to listen critically yet, plus no super tweeters running yet anyway.

So a little assembly details.

In handling the horns I noticed that they ring like a bell when banged with any metal. And even though I donít imagine that any metal will ever touch them after they are installed it made me wonder if other forces could entice the horn to ring. So to be on the safe side I did a little experiment. I filled one of the open rib areas with polyurethane. After letting the polyurethane set up overnight I tested to see if I could hear any difference. You be the judge. YouTube

Between the horn, mid and woofer there are 20 mounting screws required. I didnít want to just use wood screws. Threaded inserts are the least intrusive to install, but I had had a bad experience the last time I tried to use them. After a little googling I learned I had installed them the wrong way. You would think that the slot on one end is for a screwdriver to screw them in. Could be, but not a very easy way.

Easy way is get a screw a little longer than the insert and run a nut almost all the way on before you spin on the insert, with the slotted side away from the screw head. Then tighten the nut against the insert.

C7601FF4-2E7E-4C3D-80C9-A2285E5C192C.jpeg

With pressure and a screw gun, screw in the insert until the nut bottoms out. Then, still holding the screw gun tight against the screw, use a wrench and loosen the nut away from the insert, then back out the screw.

Clean, easy, fast, no issues. The slotted part acts like a knife to cut the wood as it screws in.

Couple of assembly pics. I covered the inside of the entire enclosure with recycled denim insulation. In addition, I added a couple layers of Acoustilux to the top of the cabinet and filled a couple inches in the bottom with loose fill Acoustilux. The mid cabinet has the one layer of denim insulation and is almost filled the rest of the way with Lambs Wool. (Forgot to take pic)

Did I mention these are BIG!!, my wife is giving me this look like ďI hope he hates them and builds something elseĒ. For reference thatís a 65Ē TV.
