Official Epik Subwoofer Thread - Page 206

I wish Epick would have somekind of showroom at their location that potential buyers could test them out before they buy them....
Right now I am deciding on two Dragons or the ULS-15 dualdrive... a few hundred difference price vise.

As far as performance wise, I think two Dragons will get you more output than two ULS-15's, but the ULS-15's will have better extension. Of course this is room dependant.

My Castle is also on its side to fit beneath a projection screen. It sounds great

Yours is no good in that big room. You should sell it to me and get a Dynasty instead.

Equidistant from the driver center and the ports would be impossible, however, if the floor boundary on the bottom could be considered the port, then it is possible.

Here's the measurement of the u l t r a 15hz tune.

I would prefer a 20-21hz tune to help reduce the dip at 23hz. Any guesses how much I would need to raise the Phoenix to change the tune to 20hz?

I bet if you talked to Chad he would be able to assist you.

Tuning to 20-21hz will not help you with the dip at 23hz. The rise you see below 20hz is due to room gain.

There is no difference in the dip between 15hz and 20hz tune on the Ultra.

Good observation, I totally agree.

Does anyone have any suggestion on treating this dip at 23hz? Room mode says it is a 25 ft dimension.

So when using Audyssey that dip is still present at 23hz?

I ran Audyssey this afternoon once, but need to run a few more times since I started, as recommended, with the sub gain at 12 o'clock. The sub level on the AVR was -11dB after Audyssey calculation. I need to lower the gain on the sub to get closer to -3dB on the AVR. I have not re-measured with REQ after running Audyssey.

Does Audyssey correct the LFE channel? If so for what frequency range and what is the resolution and bandwidth of the corrections? There's no way to view the resulting EQ for the LFE channel.

I believe you have the Denon 2808? If so, yes, Audyssey will EQ your subwoofer, but I am not sure of the details. I have never used a receiver with Audyssey.

If someone wants a dual sub setup is getting a pair of Dynasty Subs that much more effective than a dual Phoenix sub setup?

I know that a Dynasty sub has more over a Phoenix sub, but at what point is having 2 subs overkill?

I don't see any posts regarding dual Conquests or dual Dynasty's. I have seen a few posts regarding dual Phoenix subs.

If I was going with one sub, then the Conquest or even the Dynasty would be an easy choice. But with 2 subs, then there's the Dynasty and the Phoenix subs.

Does dual Dynasty subs have that much more to offer than dual Phoenix subs? My use is totally home theater and I'm looking for output and bass extension.

Looking at the dual sub possibilities is where I start having a mindblock. Any thoughts? Thanks

Audyssey will do a little for the dip, but probably not get rid of it....just not a good idea to boost a dip by more than a few dB's.

Yes, very true, however, he may be one of the lucky ones and get some improvement.

That's far more tempting than you may realize...

If you lived locally and there wasn't the issue of shipping the darn thing I might just do that

Enough daydreaming...must...be...content....

Just wanted to mention that the Phoenix graph I posted on my sub comparison post did not have the same y-axis scale as the u l t r a graph. Here's a link to my post: Phoenix vs. u l t r a

I've adjusted the y-axis of the Phoenix graph using MS Paint's Stretch reduction feature, and i've manually traced the u l t r a ' s FR onto the reduced graph.

Were the two measurements taken with no EQ? What about the crossover setting?

The difference above 60hz looks very strange.

No EQ for both. The Phoenix has xover set at 90hz in the AVR, whereas the other sub had xover bypassed. Xover is set to maximum (bypass) on the Phoenix amp.

Are you saying the Ultra had no low pass selected all? On the AVR or the Ultra amp??? Perhaps then it defaults to a high frequency, hence the difference above 65hz is due to a much higher roll off setting in the ultra ???

It was too long ago for me to remember exactly if I had the soundcard connected directly to the ultra sub or through the AVR. I know for a fact the xover on the ultra was set to maximum (bypass). Also, I had just received the denon 2808 at the time and was still learning how to use the new features of the receiver (coming from a very basic AVR receiver I'd had for 10 years).

I need to investigate more about > 65hz since I'm having trouble defeating the crossover in the AVR. I might have to connect directly to the Phoenix amp.

If I have the LFE xover on my AVR set to 90hz, will the rolloff begin at 90hz, or below?

Also, I have the LFE out on the AVR connected to the LFE in on the sub. Does anyone know what the input labelled "crossover" on the Phoenix amp is used for?

The "crossover" input utilizes the subwoofer amps internal crossover filter. The "LFE" bypasses the internal filter.

I'm sure this subject has been discussed, just hard to find in a thread this long. I personally love the size/shape of the Phoenix, but if I bought one sub at a time, maybe 6 months apart, would one Phoenix suffice? thanks

All the Phoenix owners that post on this thread, including myself, just have one Phoenix. I am more than satisified with just the one
Order the Phoenix, or two, already!

I think that is why the big difference between the two > 60hz or so.

The Ultra has a bypass switch. If it's engaged, it doesn't matter where the dial is set. The pre/pro handles the xover.

Gov: Just seeking advice from owners of these subs since I am not familiar with them at all. I'm trying to decide between Epik and Elemental Designs and why people chose one brand over another if they chose Epik, which model and if 1 or 2 was good enough for them.

Jimmy: I was on that same boat. 18" sealed. I choose the Dragon over the ED's A7s-450 because it fits my space. True 15hz extension compared to ED's 22hz. I opted for the 600w instead of the 550w. The ED's 1300w, optional, was too much. I also like the black one over the ed silver color. Even though the weight is not that big of an issue, I prefer the lighter Dragon one.
