Official Epik Subwoofer Thread - Page 205

Dynasty has 3db more output below 30hz and has deeper extension by 2hz (14 if I am not mistaken). Larger box just makes it a KICK ASS "get low-low" sub. I am sure it could create some serious pressure down low! Not that the Phnx is a sluch though. The tradeoff is that it is MUCH larger and it may b difficult to go with 2 down the road unless one has allot of space.

I just got finished watching TDK at -7dB MV and the bass in that movie was incredible!! The Phoenix handled it with ease I wanted to turn it up higher, but I really cannot take much more. The hospital scene was freaky good and just kept rumbling with deep low bass

Thanks for the kind words and glad you liked the post!

I finally have a good seed system (2.1) now to build upon, to recreate (and hopefully improve upon) the 7.1 system I created (and sold off) using Magnepans all around.

I am building DIY full range LCR speakers, open baffle, active crossover, quad-amped (an homage to Linkwitz' Orion but using different drivers, enclosure, amps and EQ)

The Valors will be used with these DIY mains but the crossover will be dropped down to 40, just to support the lowest octave of the dipoles.

At that point, I will be getting a dedicated LFE sub, probably a Phoenix (with ports stuffed) for the largest sealed 18" sub I can afford, EQed with the Antimode 8033.

Cheers

Hey Robobob - Like yourself I wanted a full on HT in my living room (over 6000 cu ft) and went with vintage Polks all around. Mains are SDA SRS 2.3's, surrounds are RTA 12'S, and the rear surrounds are Monitor 10,s set up THX style. Pics of my stuff are not up to date on the site as yet. Subs are dual HSU 3.3's with dual MBM-12's with Anti Mode all the volumne for the bass is handled with a Paradigm X-30 crossover controller.

U l t r a 2 0 h z t u n e



IMPORTANT NOTE: The y-axis scale on the Phoenix graph is not exactly the same as the graph of the other sub. The Phoenix graph will appear to have higher peaks and lower dips. Also, I don't remember is if I had run Audyssey with the u l t r a before taking the measurement.

^^^ Joe, it looks like the Ultra does much better in your room? Was that with the 20hz tune for the Ultra?

20 hz.

Here's another seating position which actually sounded better to my ear even before taking the measurement:

Seems like the Ultra has better mid-bass than the Phoenix in your room. It terms of what you are hearing, which do you prefer?

xover is set at 90hz on my denon 2808. I can't seem to defeat the xover in 2 channel direct mode. xover dial on the sub amp doesn't seem to be doing anything either.

Gov,

What frequencies in the midbass are you referring to?

Above 60hz. Although, I admit that I am not the best at reading those graphs. It just appears that the Ultra is showing a bit smoother response

Might be a silly question (what's new).

Can these subs be placed on their sides and if so, does it affect their performance in any way? I think I saw a picture of two Conquests subs on their sides.

I had a thought about either getting 2 of the Phoenix subs, or getting 1 Dynasty and at a later date/time, getting a 2nd Dynasty. Does anyone think that's a workable solution? I'd love to have something like the Conquest, but don't think I would be able to work with 2 of them.

Using one Dynasty could last me until such time that I could ad a 2nd one and not feel like I'm missing anything with just one.

It's hard to get an idea of size and shape from the pictures on the website. One of the posters here has a pictures of his Phoenix sub which looks very nice, maybe because it's a cube shape design. But it's hard for me to get a feel for the size and shape of the Dynasty. Anyone own a Dynasty who could post a picture? Thanks!

The Phoenix cannot be placed on it side due to the port design. The other subs reportedly can be.

Gov: thank you

I had yet another question. If your receiver or processor has one "sub out" and you have two subs, what is the best way to handle this? I had a receiver up until just a few weeks ago when I replaced it with a processor.

My processor has outputs for RCA as well as XLR connections. Before, I had used a "Y-splitter" to connect 2 subs to 1 output. How would I handle this and want to connect all of my equipment with XLR connectors?

Instead of splitting the signal, could I use 1 balanced sub out for one sub and then one RCA sub output for the 2nd sub? Is it posible that you can get a balanced interconnect cable that "splits" for 2 connections?

There really was no way around this issue for me when I had my receiver but now I have a balanced amp and processor and I like using the balanced connectors. I'd like to take advantage of the balanced inputs on Epik's subwoofers. I'm at a loss as to how to make this work. I thought about one RCA out and one XLR out, but I'm sure I'd be messing up something. Any ideas/suggestions on this issue? You guys who with 2 of these Epik subs (lucky guys) must have run into this issue at some point. Maybe I'm totally overlooking something very obviousl. Thanks!!

jimmydaves:
what benefit does the balanced connection give? i ask this because i dont know?
i know the old line of epiks didnt have this, and they are very capeable subs. does the conquest even have this feature?

Room EQ Wizzard, allows you to take measurements from multiple seating positions and average them, try doing that. Also are you using Audyssey? Also what equipment are you using to get those graphs? Please don't say a soundblaster and a radio shack SPL meter, .

this post should help you with the Conquest:

http://www.avsforum.com/avs-vb/showp...postcount=4352

and if memory serves, craigsub said it sounded better on it's side

Yes, REW, SB external USBlive 64 with RS SPL meter (w/calibration files for both). Output of soundcard is connected through my AVR and crossed at 90hz. I have not yet Run Audyssey MultiEqXT with the sub connected. How much correction is performed by Audyssey below 100hz (number of corrections, and bandwidth)?

Here's a close mic (pretty close to the graphs published on Epik website - about 5-6dB down at 20hz from 50hz):

I don't know the question to balanced inputs. Why do Epik subs have them and Elemental Designs Subs do not? My processor has balanced outputs and my outputs for all my channels have balanced connectors. Why not use the balanced connector for the Sub as well, if it has a balanced input?

I still haven't heard what is the best way to hook up two subwoofers to one sub output though. That was my main question.

Joe, can you run Audyseey for both to get the gain dialed in the same for both? Then crank it up to reference levels! I will like to see a "true" comparison in overall output and freq response.

Tony please post some pictures! I would like to get an idea of the size in the real world. Thanks

There are many ways to do it...you can use the rca splitter (solid is best), have a custom XLR splitter made (have done it with signal cables) or use the xlr and rca line outs simultaneously. For the first two options, good pre-pros have enough line out voltage to drive two subs evry easily. On the third option, usually the xlr and rca at different gains...calibrate the xlr first...say pre-pro sets 75db at -3db, then shut down the xlr and connect rca and without changing pre-pro level, adjust from the volume of the sub...for xlr, keep the volume at 11-12, you will end up at max 2'o clock position,

Good luck!

Sorry, I cannot compare since I only own the Phoenix. A friend let me borrow his sub ( i did not take max output measurements of this sub, only Freq resp) and he no longer has it due to financial reasons.

I use my Castle on its side to fit beneath a low projection screen. Chad said he has his own demo Dynasty in the same position for the same reason.

Ok now it makes more sense. You are just comparing today's measurement of the Phnx against your old pb13 measurments in your room. Gotchya! So if it is 5db down at 20hz, I suppose a Dynasty would be 2db or so down at 20hz. It appears the Phnx would be best compared to the pb13 with the 15hz tune intact. Agreed?

XLR inputs really only make a difference if you have a long cable run to your processor. Otherwise, they are just a conversation piece so to speak

You can definately tell that the Phoenix tuning point is about 18hz or so by your graph.
Also, your frequency response is pretty good with no EQ
I can wait to see it after EQing

You may want to try the measurement equidistant from the driver center and the ports. The location of the current measurements might not be close enough to the ports to accurately measure the output at and around the tuning frequency, thus the 5-6db drop from 50hz.

Hi guys,
I just sold my Klipsch THX Ultra2 subs.
I am ready to buy some epik subs my room is 13x25x7.5 enclosed basement room.
I am thinking about a pair of their Dragon subs what you guys think...
I use my system mostly 90% movies and some video gamess maybe 5% music....
My other options maybe a pair of HSU ULS-15 dualdrive...
I am in Chicago so I could pick up the Epik subs versus shipping.

One Phoenix or Dynasty would be awesome in your room! But, if you are looking specifically for sealed duals, two Dragons would be just as good!

If you're 95% HT and gaming, you could probably just go with ported subs. Two Phoenixes should rock the house.
