Lab Gruppen FP14000 clone amplifiers - Page 9

post #241 of 4398
I would think that if your saving enough money when buying the clone you might as well use some of the savings towards a 20amp powerpoint atleast. No sense in using a standard 120vac with one of these monsters unless you like trip breakers all the time.

I see what you mean, but they will pull double duty for the occasional DJ gig; most people don't have one of those outlets at their homes.
post #243 of 4398
You need a dedicated 30a @ 120v circuit or a 20a @ 240v in order to take advantage of the full output those amps have to offer.
post #244 of 4398
I think if you actually need the wattage then you might have to use smaller 2400watt amps and multiple powerpoints for the dj use. I am on 240vac and have a two 20amp powerpoints for my sub amps.

If I was going to need a very powerful amp for say my bass guitar I would have to limit the amp to a 2400 watt amp or not actually need 2400 watts. I know the amps are capable of bursts also.

I would think any venue you would DJ would have some suitable powerpoints for you to use like a 20amp one. Unless you are just starting out then yes you wont have that option.

I have chatted with Mark about the 21's and he said they will just be single 4ohm binding posts. Or I he could do dual 2ohm for slightly more money. Now my dilemma is can I still get the Fp14000 amp with single 4ohm binding posts or even dual 2ohms?

I was thinking of dual 2 ohms but when only having a single sub per cabinet in the beginning I will have to run 4ohms per channel. Which would be I believe to much. But when I get the other pair I can then wire them for 4ohm and have what I want in 4ohm stereo.

SO do the limiters work at all? Because I dont want 4400 watts destroying my new 21 because I felt like seeing what it can do. I figure I wont ever push them this hard but I said that about 600hp diesel and didn't take long before my grandma right foot destroyed the tranny.

Limiters seem to work fine on mine.
post #246 of 4398
Well if the limiters work then I should not have a problem with single 4ohm binding posts or dual 2 ohm.

I thought Bossa mentioned the limiters didn't work but I wanted not to clarify or anyone else. So that is a huge plus. Thanks hypez
post #247 of 4398
I think bosso's limiters failed after a while.
post #248 of 4398
Oh ok

Well hopefully mine wont fail or atleast I'll have another pair of subs for the 4400 watts so the limiter wont exactly be needed.

Either way great to see this amp is atleast a complete functioning amp which can deliver the wattage it is supposed to.
post #249 of 4398
I see your points brought up. I just figure I'd get the most amplifier I can get for the money. I will be probably selling my Crown XTI 2000s to get these.
post #250 of 4398
Just found this link to a place here in the UK which sells the originals.

can you share the secret behind the awesome bend you were able to do on the screwdriver? i tried today, and i ended up with a super bend

There's no secret really, use a torch, heat it up to glowing red, bend it. Repeat as necessary until you get the bend you want. I just used a pair of pliers, but it would probably work better with a hammer on an edge. Unfortunately, I don't currently have a good work bench setup. That's one of my next projects. I make do OK though

Anyway, the tricky part is in cooling it Too fast and you have a brittle tip, too slow and it will be soft.

There are store bought options; an offset screwdriver, whereby there's a phillips on one end and a slotted on the other. Also, and even better, a ratcheting, tight confines screwdriver, again either phillips or slotted. Looks like a small socket wrench. Indispensable

Good luck

Store bought options are all too big. There is only about 3/8" of space to work in.
post #255 of 4398
3/8", wow! ... that said, phenomenal job with the bend

Also, I'm out on Long Island. If you need help, you can just bring me the amp(s) and fans.

thanks for the offer, will definitely consider that!
post #258 of 4398
I replaced the fans in one of my FP14k's. The learning curve for me was kinda steep with this mod, but I managed pretty well eventually. One tip I can give to whoever is going to replace the 60mm fans, use a small zip-tie instead of the bottom screws on the 60mm's, saved me a lot of frustration with those zip-ties.
The fan replacement made a huge difference in the noise level needless to say.
post #259 of 4398
Not did you say that these 60mm fans still keep the amp cool?

I think you did but I didn't remember how hard you pushed your amp. I am still waiting for my amp to sell then I am off to buy one of the clones. I like the fact that the front panel lights dont light up the whole room like my Crest does. Either way I probably will never push the amp as much as you do because my house would fall apart first.
post #260 of 4398
Are these LG clone amps more efficient than say a Marathon or QSC? Meaning if there is 20A available, will the Lg be able to do more with that 20A than other types of amps? Trying to decied if it would be worth it to buy one down the road since I have an LMS with passive radiators and I know I wouldn't need that much power, but the cost of one is the same as a much lower output "name brand" amp.

You might try reading a thread for the answer, since I've said it multiple times.

I'll say it again though, yes. By a good deal.
post #262 of 4398
My humble appologies... I read the thread and apparently missed it. Thanks for saying it once again.

Anyway, onto the good stuff. These amps are monsters. My subs go so much louder now. Easily +6db over the MA-5050s in stereo mode at 4ohms (tested at 10hz). When the bass hits, it literally dims the lights in my house. I have 200a service. The amps are connected on four 30a breakers at 120v. The displays on these are nice. They will not blind you, and have nice level meters.

Actually I don't see the answer to his question there.

6db+ gain over marathon amps on the same circuit at the same power draw.
post #266 of 4398
So what is the verdict on these? I've read over this thread a bunch of times too but I just don't know.

Are they worth the risk? Those FP10000Q's would be really, really awesome for my active uber LCR's and subs.
post #267 of 4398

For sub duty, I'm sold. These things are amazing. I can easily overpower a pair of sealed 5400s on a single amp. They just sound incredible and clean. Can't comment on FP10000Q for full range, since none of us have one yet.
post #268 of 4398
I am really interesting in both the FP14000 and the FP10000. I would use them to power (at the given moment) quad Sound Splinter RLp18d4's and twelve JBL 2226j's. I would use the FP10000 for the JBL's and the FP14000 for the RLp18's.

The small footprint of these amps including their power/price ratio has me sold. Not sure if I have what it takes to replace those fans though. I think I'd end up tearing my hair out or punching something if I were to attempt a fan swap. *laughs*

There any talks of a group buy again? I might be down for some of these this summer if things go well.
post #269 of 4398
I can attest to the improvement in notnyt's subs. I have been fortunate enough to hear the before and after. I didn't think it could get much better. Boy was I wrong! The bass is so much stronger, louder cleaner etc. I say go for it Scott!

Ah; the quoted post doesn't say anything about power draw
