Re: 2 x 15 cu ft FIQ18 multi tuned ported subs

A small update for you. I have now glued the first port piece to the bracing and baffle so I will give it a few hours before I glue the second port piece to the other baffle.

cheers

Re: 2 x 15 cu ft FIQ18 multi tuned ported subs

Ive been back out in the garage again and glued the second port onto the rear off the bracing. So that is now drying. I have put a few screws in the back off the port on the other one just to secure a bit more. I have filled the holes with filler. Fingers crossed tomorrow I will add the first coat off primer to the port.

cheers

Re: 2 x 15 cu ft FIQ18 multi tuned ported subs

A few more pics to show it standing up. I have also added some filler where the port exit joins the top piece to make sure it is dead flat and smooth.

I have added one coat off primer to the inside off the port piece and wet sanded down and I have also glued one off the sides on the first sub so I will do the other sub today and take some more pictures.



cheers

Awesome build Graham! I love the bracing. It will be interesting to hear your impressions of the "multi tuning".

Re: 2 x 15 cu ft FIQ18 multi tuned ported subs

Nice to see another huge sub build.

Hate you right now.

I will have to wait sometime before I can do my all out monsters so for now I get to watch others with envy/jealousy.

I cant complain to much though I will atleast have my THT to get me by.

Re: 2 x 15 cu ft FIQ18 multi tuned ported subs

Hello fella!

Yep I decided to make them a bit bigger. LOL.

Lots off priming and painting to do then just case of putting the other side and back one, then veneer.

Its sound so easy. I wish it was.

cheers

Yah ....I also cant wait to hear what you think of the 18's?

They have them hear in Oznation for about half the cost of the Maelstroms so I'll see what you think of them.

I remember you were working on a pair of dual ported malx subs weren't you. Do you remember I did some sketchup drawings for you and some graphs.

Very impressive design and build. I hope you'll be giving us some REW measurements once you get this thing situated. I'd be very interested to see the performance of each tuning in room.
