Good afternoon everyone. My brother in law and I built my box the other day and it is time to show the progress. The box is currently with my neighbor who owns a custom car shop and is putting a coat of bedliner on it.

I must admit however that I am not too terribly proud of the workmanship but I think it will do for a first attempt. I followed the dimensions provided by Kevin in this http://www.hometheatershack.com/forums/exodus-audio/21979-first-tempest-x2-design-easy-slot-port.html thread. Only a single sheet of 4'X8' MDF was used. My dimensions ended up a little different and yielded 5.7^3 ft and close to 6^ft with 80% polyfill.

We performed this task with the following tools; Skil-saw, jigsaw, hand held beltsander, finishing nail gun. I know most of you use clamps but I was rather impatient and didn't want to wait. Instead, we glued and nailed the pieces together and I predrilled a few holes on each piece and screwed them snug, knowing that any imperfections would be covered by the bedliner coating.

Just getting started.

Cutting the hole for the amp.

All pieces cut now ready for assembly.

Partially Assembled

Test fit of the :hsd:

Bracing - does it need more holes???

T-nuts used

Hardware used to fasten the sub.

I will post the final product when I get it back....

Finished but not yet in its final resting place...

Thanks for checking it out...

bigdisu1: It hits hard and sounds great but since I have the wrong amp it doesn't go very low...we watched about 10 minutes of Letter of Iwojima and it seemed as though we were onsite. The sub is quite impressive and I look forward to putting the correct amp in when it arrives.

Go for it.

When you get the new amp, if you could, write a reply and let us know you thoughts. I am really interested in your opinion after you get it set up the way you wanted.

Thanks!

What other subs (if any) have you had a chance to compare to? By the way, those cuts are pretty impressive considering no table saw:T

Ok, I have had the HSPA500 amp for a day or two so allow me to give you my impressions. I first had a HSU STF-2 10" ported sub. Nice sub but lacked in the 60hz+ arena no matter what I did. Great little sub though...

Since I have been sick with my wife and kid out of town I have had the last two days to play with the TempestX-2 and watch too much media. I am very pleased with the outcome. I am hearing/feeling frequencies I hadn't before. The sound quality is better/sharper and naturally the quantity is far more than I had or even need. But none of this is about need is it...I have a brand new house with a 14X16X(10-11)vaulted funny ceiling media room. Where I previously had bass dead spots there is envelopment. I will now need to work on making things rattle-proof, i.e. sconces in media room, door down the hallway, etc. :hsd:

I continue to push the setup to check the limit but have yet to find it. I recall Kevin mentioning that this 500W will never reach the subs max but I still try to be conservative.

So, I watched War of the Worlds, Transformers, Dark Knight, and Hulk. Now I may not be able to watch movies while my kid is sleeping...:devil: She has been used to the STF-2 since birth but this is another world.

Current settings: I ran Audyssey with the gain on the amp at 60% and haven't touched it. All other settings on the amp are all the way down. Haven't played with the parametric EQ or anything else yet. Not too sure what to do there but I'll figure it out.

Thanks Kevin for a great sub!

Any questions?

Brian,

Good.... sounds like you have enough output for your room. If you have Audyssey measuring and adjusting the sub, you shouldn't need the PEQ setting on the plate amp. Leave it alone once you run the Audyssey.

In Kevin's build notes when talking about 80 or 100% fill. What is that ratio? Is it 1 pound of acoustifill to 1 cubic foot for a 100% file rate?

Kevin - Will do. Thanks.

jinjuku - I had found one of Kevin's threads that helped me determine how much I needed. I ended up using 60oz of polyfill since they come in 20oz bags. According to my calculations I think I needed around 65oz.

Yes.... 1lb of fill = 100% fill. It doesn't need to be exact. You can be off a large amount and it makes only minor differences in the final response.

Good evening everyone. I am resurrecting this thread for two reasons. First, this subwoofer has been great to me. Second, the HPSA500 has died (the auto-on switch, supposedly) and a friend is letting my use his Yamaha P7000s. I can cover the hole the plate amp left in the box and start using the Yamaha but having little experience with this amp, what do I need to know to not push the sub too far?
It seems to have some filters on the back of the amp.

Any help appreciated.
Brian
