Why take some out. I think it's fine. Hard to over stuff a sealed box.

Measurements look good. Akin to a ported response, which is odd. Good though!

The dimensions you listed above, those are external dimensions correct? So your internal volume is about 4.6 cu ft?


Do you have any measurement equipment to check our frequency response? What are your impressions so far?

I'm still struggling between this driver and the Dayton RSS390HF. Decisions, decisions.

Can anyone give this guy some advise on the HF15 versus the UM15? I am curious as well.

Not odd when including room gain and an amp with some boost.


This is a single Tempest X in 3 cu ft, downfiring, at the 1/3 point of the front (long) wall, full range. Note the varying effect of the filter settings; the 16Hz setting looks a lot like mad's curve below 40Hz. It's what I use.

Also note that features like the "spike" can vary strongly with mic placement. Here's some data for my room, dual subs, after Audyssey and PEQ adjustment.


The 4 positions are a ~3' diamond around an on-axis listening location. About the space you take up with hands on hips; mic positioned at your elbow. there's a 25dB dip at 41Hz, but localized so I'd never be able to hear it with both ears at the same time. Not worth addressing in my book.

Make sure you move your mic around before you determine there's a problem to fix.

HAve fun,
Frank

PS the Ultimax series is comparable to the Tempest X at a reasonable price. Hard to beat, sealed or vented in my book.

I meant odd that there's room gain to 20hz and then stops dead. You examples (and the examples I have) shows that the gain extends lower, which is more normal. His result is a little odd and looks like what we'd expect from a ported sub. No big deal though.

That's the infrasonic filter... a good sharp cut-off. Boost and room gain up to that point, then it drops like a rock. Look at my native 16Hz fitler curve; very similar shape, right down to the overshoot.

You can't use the second chart as it includes Audyssey and PEQ effects.

HAve fun,
Frnak

Do they sell roll on hammered paint at the big home improvement stores? Is whatever you used real durable?

I really like the way it turned out with the hammered paint. I bough it at orchard. They sell it at Home Depot too. Use a good roller so it doesn't shed. I sanded it down a little after to flatten it out. I rolled it on, then hit it again with the roller all in the same direction to get the desired texture before the paint sets up. The longer you wait to re-roll it, the more aggressive the texture will be. I waited a little long which is why I had to sand it down a little. After I used so semi black to get the color I was looking for.

It seems like a great way to go. Thanks for the tips. Did you use a roller that was fairly flat, or did it have some nap to it?

I think it was a 1/2 inch nap. When I finished my statements, I rolled two coats of primer on. Then I rolled two coats of semi black on. I did not sand it and I got similar results. Maybe a little less texture. Either way I'm very happy with the results.

It is just a little under what I want (for now) in this room; so I've decided to build a ported Dayton 15 Ultimax rather than to double or triple the budget. I have a 300 Watt amp to test this unit out with and I'm thinking that if it goes well, I will end up building a second and getting an ep4k or similar to power it all. I am new to winISD, but I think I'm going to go with a 6^3 ported enclosure tuned to 15Hz with 2 ports that are 3 inch diameter and 25 inches long. Any thought on how this will perform in comparison to my current setup, or suggestions on different enclosures?
Hello. I am interested in getting this sub but am having alot of difficulty trying to enter the perimeters into Winisd. Is there any way you could screenshot the driver parameter screen so I could start modeling? Thanks so much.

uncheck the box at the very bottom that auto fills in other parameters

I couldn't be happier with it! And that's only with 300W.
I run the UM 15's in 4 sealed cubic foot boxes, don't be afraid to add more power. They just get better!!
I am running about 700 watts into each rms and have never bottomed the driver or heard any weird noises coming from them.
