post #19921 of 20352
For the Legend I would look at the Behringer iNuke nu1000, in bridged mode, for around $200. It may even have enough oomph for the Legend driver in stereo mode using a single channel. I'm using an iNuke nu3000 (one channel in stereo mode) for an Empire with blown amp and it seems to be quite happy.

However the stock fan is really quite noisy, so if you are unsure about replacing it with a Noctua or similar, maybe spend a bit more on a quieter amp like a Dayton or Crown, tho I cannot attest to actual perceived noise comparison to the Behringer.

IMHO, YMMV, etc,

On stock amp I never went above 75% onboard nor above -3db on sub out on receiver. I'll also say the increased low end extension could also be in part due to the effectively larger cabinet. By taking the guts of the amp out of the enclosure, I've effectively increased the internal size since the volume occupied by the amp can now be occupied by air. Generally, a larger cabinet will result in a lower tune (at least to an extent). Either way, I'm happy with the results smile.gif

Congratulations on the successful upgrade. I'm glad to read that the Crown amp is able to drive your Empire down to the frequency you hoped for. The reason I am posting is that I was originally considering a crown amp but was scared off because all posts on AVS saying that Crowns run out of gas below 50hz and brick wall at 20hz. The REW sweeps you posted look like they contradict both arguments. I spoke with the owner of a reputable local custom pro/home audio shop who swears by Crown and mentioned that he has had great results with their TXI line driving single or duel home subs. He recommended the TXI line because of the advanced EQ and DSP capability. In short, I want a pro amp under $500 with enough power to drive dual Legends into the mid 20 hz range without premature clipping. I know that compact sealed subs require eq boost to maximize their sub 40 hz performance, so I will need parametric eq.

That leaves me with a choice between the Crown XTI2-1002 ($499). Vs the Behrinenger Inuke 3000DSP ($399). The Inuke seems to be more powerful, and is used heavily by the DIY sub crowd, However, the Crown is the more reputable brand, doesn't seem to need a fan modification, (say goodbye to the Inuke warranty) and I like that my local dealer will be there to support me before and after the sale.

Maybe I'm over thinking this.

To be clear, I have Sentinels, not Empires. Between the two you listed, I would get the crown just based on the aesthetics alone lol. That said, reputation is important. One amp rated at 1000W might not put out as much as a reputable amp that is rated for 500W. It depends on how they rate the output, at what THD, at what frequency, for how long can it maintain that output, etc.

Hey guys. Quick question. I've read this forum so I'm aware of what's going on with these subs. One of my 2 legends blew a few months ago. I've also had no luck calling Epik. I want to try changing the fuse since I haven't done that. Does anyone know where that is located? Sorry if it seems like a very basic question.
post #19925 of 20352
Where the plug is, there is a little drawer that you pull out and the fuse is in there. If you put a new one in, it will blow. Theres a reason the first one blew.

I still have a working 600W Epik Amp from a Sentinel for sale for anyone interested. I believe it is the 215mm x 285mm size but can double check if anyone is interested. I'd like to get $140 Shipped.

My Legend Sxxx the bed. 

 

I have a EE friend who is going to try to fix it.  We think it is the output transistors.  If that fails I think I will try to put in a new plate amp.  I'm looking  at the Bash 300s or the Yung 300 or 300-6.  Woodworking is not a problem for me so I can modify the cabinet easily.

 

Any recommendations on the replacement amps?  Do I need or want the 6db boost?

 

Any thoughts would be appreciated.  I don't want to use an external amp.

post #19927 of 20352
Please let us know what the issue was
post #19928 of 20352

Will be glad to.

post #19929 of 20352
I never thought it would happen to me!... well, actually, reading all of the horror stories on this forum it I knew it was only a matter of time. My Legend just crapped out on me today. No power at all, so it sounds like my amp decided to go defective just like everyone elses. I emailed EPIK, won't be holding my breath for a response. So, from what I've read my only real options at this point are:

1. dump the whole thing

2. get an external preamp


So, I looked up the iNuke amp. What are some others in the $200 or lower range that would work well with the legend.

Thanks in advance.

Joe

Man I sure hate to see all the people with messed up Epik subs out there. What a shame Epik had such great potential. Maybe someday they will get started up again. Fortunately my Towers have been performing great for years. MollysTower.JPG 854k .JPG file

How much more output do you get from the "woofer" on top of the woofer? :D

post #19932 of 20352

The real shame is Chad's lack of response.  If I could just get my hands on the schematic for the amp in the Legend I have several very talented Electrical Engineer friends that could help figure out what is failing and suggest what parts we would need to replace to repair / upgrade the units.  We are going to try to do that to mine next week by trial and error.  I will post our results.

 

If that proves fruitless then I might try to replace the plate amp with either the Bash or Yung units.  Modifying the opening will be a piece of cake.  I just don't know which amp would be the best to choose from and so far have received no feed back in this thread.  I was hoping someone else has tried this by now.

Let us know how it goes. I have a pair of Empires, it'd be nice to have a plan if they die.

When I bought them at Epik, I told Chad I'd be more than happy to take over his operation should he decide to hang it up, shame this is the result.
post #19934 of 20352
so after considering a Dayton sub1200 and BIC F12 and knowing that they would probably be stop gaps until I could justify buying an SVS or HSU i'm thinking that changing the plate amp all together may be the way to go.

I looked at the Bash 300w or Yung 300w amps. Do these amps have the right connections for the dual woofers that the Epik Legend has???

If it were me, I'd be looking at an amp that had a little more overhead than zero. That's likely what gave the original amp such a short life span.

My failed amp had swelled capacitors and a few surface mount IC's and resistors that were so charred that they couldn't be ID'd. Part of the board around this area was also burned and the traces had gaps in them. Basically, this part of the amp was irreparable other than to replace the board (there is a main board and two smaller boards attached).

My amp looks visibly ok we disconnected the two small control boards from the large main board. After doing that the fuse didn't blow when you shorted out the lfe input and you could here the relay working. The caps look ok so we will try the transistors first.

As far as hooking another plat amp to two speakers. You just connect them in parallel. If you open up the unit, it will be obvious how to wire in the new amp. You just need to be sure the amp will handle the 4 amp load. Both of the ones above will.

Thanks, I've removed the plate amp from the box. Shouldn't be hard to connect. I'm going to see if I can get a replacement from Chad first (not really holding my breath) but i'm going to give it a shot and see what happens. BTW, Who was the last person to get a replacement from him???
post #19939 of 20352
Mines in warranty but I gave up calling. Let us know if you have any luck.

Well, that's good. I'll try and hold out hope but if I can't get a hold of him by the end of the week I may just give up. I tried watching iron man the other day without a sub just to see if I could tolerate it. No thanks, even the dialogue is worse without a sub. I guess it will be all music, video games, and talky movies until then.

His shop is about 40 minutes from me. I would be happy to go up there when there isn't anymore snow on the ground.

I'd be surprised if he's still there.

Thanks, I will keep everyone posted about whether I can get a hold of him this week or not.

I just switched out my blown Legend amp with a 300 watt BASH amp from Parts Express. The amp is a bit larger in dimension, so I had a local PA speaker builder test the drivers, then retrofit it into the box. So far so good. The BASH amp does have a small db bump at 35hz but not as much as the original amp but combined with my second Legend, I'm not sensing any dropoff in performance from the original amp. All I am running is the Multieq that is built into my Marantz AVR, but am thinking about picking up a mini dsp unit and USB mic to further tweak the system. All in all, I am happy with the decision versus dumping $400-600 into an outboard pro amp.

That's good to know. I've been thinking about getting the BASH or the Yung 300w amp from partsexpress and possibly reselling them if I can get a replacement from EPIK. Any reason why you went for the BASH over the Yung?

Is there a pattern to recognize with all these defective subs? Is it mainly with the Empire and Legend subs? I am the owner of two Conquest subs and I'm starting to get a little nervous frown.gif
post #19948 of 20352
I don't think the issues with bad amps are that prevalent. Mine is running fine and I am rather certain most other are OK as well. That said, it does appear Chad is avoiding responsibility for the bad amps and is not responding to warranty inquiries. I have to admit I can't understand why is website is still active and why in June he made an announcement about new products on the horizon. He must be having significant personal difficulties.

I'm glad to hear the Bash unit is working out OK, That is my plan B.  By the way I just ordered the Antimode 8033 Cinema to use with the Legend if I get it working or with it's replacements.

My Legend just quite on me a few days ago. It was solid for 2+ years. The warranty expires in Feb. 2014. No warnings that I noticed. It just went out. I would like to think that if your conquests are older than my Legend that you are out of the woods. Good luck.
