Another Marty Sub

Still waiting for the SI 18" HT woofers to arrive, but most of the construction is done on a pair of them. Speakers are made using 3/4" appleply for the boxes and the front baffle is 3/4" appleply bonded to 3/4" MDF. After I get the drivers and check the fit I'll epoxy the front baffle to the box. The internal volume of the boxes is 9.85 cu ft which includes the bracing, and the vents are 46" long. The finish will be quarter sawn white oak veneer on the sides and 3/4" granite on the top.

Thanks. I forgot to mention that the subs will be driven by a Sanway FP14000 clone amp. Plenty of power there.

I'd recommend 1000-1100 watts. I run all of mine at 1100 and have had no issues. I'd also recommend you set a hpf ( high pass filter ) at about 17hz, based on your enclosure. An hpf will protect against over heating / over excursion.

Looking good man.

Also, on the back of your Clone set your VPL limiter lower.

This might help Volt/Amp Calculator.

The Denim insulation arrives tomorrow. After I install it I'll post some other pictures. The long wait is for the SI subwoofers. They must be on a slow boat from China.

How far back did you set your vertical brace? And what are you tuned at? Looks good.

Off the top of my head I don't remember how far back it is but I know it will clear the back of the woofer by 1-3/4". It's tuned to 16.8 Hz.

Time for an update. One of the speakers is done with the veneering. The upper portion of the front will be covered with 3M 1080 carbon fiber vinyl film. The second speaker is still waiting foe the denim insulation from Home depot to arrive. They screwed up my order and only sent one roll instead of six, which is what I payed for. Hopefully the rest will arrive this coming week. Her are some pictures of the one speaker:









I'm also still waiting on the granite tops. Between the granite top and the bottom lip, the sides will be lined with angle aluminum which will frame the grill.

This will give you an idea of what they are going to look like. These are my left and right channel speakers.

Granite tops will be done tomorrow afternoon. These are going to be heavy speakers as the granite is going to weigh about 100 pounds each. I'm still waiting for the denim insulation from Home Depot to finish up the second speaker. Carbon fiber 3M 1080 is installed on the first cabinet along with the angle aluminum.

Nice! When I first read that you were going to wrap them in Carbon Fiber, I though you were going to use the real thing. Have you ever worked with the real thing? Man...it's a real PITA...lol. The 3M stuff makes sense and looks great.

Awesome work my friend.

fperra,

I've checked out a few of your builds and your grill technique has me intrigued. Can you expand upon your method? In this thread or a different one, just let me know where.

fperra, how did you prepare the surface for the 3M wrap? Did you use the standard 1080 or the Di-Noc version?

Thanks a ton, I'm building my cabinets now and was looking at the 3M products, when I saw your thread I got pretty excited. Yours are looking great!

I used shellac seal coat followed by a very light sanding. On the Marty I used 1080, but on my main speakers I used Di-Noc. Either will work.

Granite tops are done.






Now I have to figure out what kind of finish to apply. Oil finish or fill the grain and put on a glossy finish. What do you think?
