Funk Audio TSAD18v1 Passive Radiator Build

I finally started the project. Originally I was looking for a high quality sub amp. This lead me to Funk Audio. Nathan and I discussed my goals for my home theater system and after many e-mails I finally settled on the system I'm currently building.

Amplifier:
Funk Audio 2.4kw x 2 version 1. This is the same amp module used in the 18.0 subwoofer. Just add another module and place it in it's own chassis.

Speakers:
Two Funk Audio TSAD18v1 18 inch drivers

Passive Radiators:
Four Funk Audio PHSAD18v1 passive radiators

Enclosure Details:
Each driver will have a net internal volume of 220L

I'll post more pics tomorrow and give a little more detail regarding the enclosure design.

Re: Funk Audio TSAD18v1 Passive Radiator Build

Those are great subwoofers Nick has. Any pics of the amp? And do you have a retail price on the amp? Is there any DSP also?

Nick has always had some of the best finishes on subwoofers I have ever seen. So seeing you are building using his products I have a lot of questions.

Re: Funk Audio TSAD18v1 Passive Radiator Build

Looks like he did include a pic of the amp and like he stated its in its own chassis

Also love more info on the cost of what you purchased from him.

I see the amp does have a menu button and a few other buttons that I cannot read

My mistake on the amp picture. It was just hard to see in the pic was all.

Awesome build! How much did the subs cost if you don't mind?

Let's put it this way. The build is going to cost me about 60% of what it would cost to purchase two 18.3 subwoofers.

I'll post some better pictures of the amp soon.

Re: Funk Audio TSAD18v1 Passive Radiator Build

I've made a little more progress. I've finished glueing and screwing the two panels of each of the sides, front and back together. I wanted to flush mount the drivers, so I used a router and a circle jig to cut out the respective holes and glued the two 3/4 inch pieces together. Instead of using clamps, I used 1"1/4" wood screws. After assembly, I'll remove the screws and fill the holes with wood putty.

Re: Funk Audio TSAD18v1 Passive Radiator Build

Are you just flush mounting the frame and adding a grille later or just leave the woofers exposed?

I know for me I added enough baffles to have the drivers surround flush so I was only curious.

I'm just flush mounting the frame and adding grills later. The piece that you're looking at is the front or rear. Four passive radiators are going to be mounted directly apposed on the front and the back. The box will lay flat on the ground. The two ends will then house the active drivers, again directly apposed. The grills will have to be strong being that they are so low.

I haven't quite figured out how I'm going to make the grills. They are beautiful speakers, so I'd hate to cover them. I was thinking of some kind of metal mesh. Like something you would find on a old PE locker

Any suggestions?

Re: Funk Audio TSAD18v1 Passive Radiator Build

Do the passive radiators have the same cones?
