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?

 

[Hagarr]

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.

Brian

 

[Kevin Haskins]

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.
