Hey all. I’m back after a hiatus from the hobby. Very very active previously. Anyway, recommendation needed for one rack unit to power (4) HS24s, two per sealed cab. Each driver is 4ohms and rated at 2k RMS, however I would like ideally 3.5kw - 4.0 true power available per driver (these drivers absorb power well and for sealed the overhead will be needed for some awe contouring) Initially one pair then the second pair added a few weeks later. Initially I was looking toward a Sanway 14k, run at 2ohm per channel (2 drivers per channel), however now since my return, there are so many options available. I’ve read a lot of the thread since I’ve been back but still not sure. Lastly, where and how do I purchase an XBS or Smiths? I’m only familiar with the folks at Sanway, who are great in my previous experience. How about Bortec Labs on EBay? Sorry for the very elementary questions, but still trying to play some catch up here and get up to speed! Happy Mew Year.

I made a post with some of the links to measurements for the amps http://01966633.com/forum/155-d...links-faq.html

To actually put 4k into each driver I think you would have to run a bridged 14k into each driver. Most people would go for an fp20k in this situation, it would max out all channels driven somewhere around 8kw total. To get max power from a 20k you’ll need a 60a 110v circuit or 30a 240v. My 14k driving two hs24 probably doesn’t get them to xmax but it does pretty well. Bortec didn’t test that well, smiths and sanway are the known good 14k. The 20k is xbs and a bunch of people have them.

Ordering is lol, get on their chat, they’ll send you their WhatsApp number, send money and receive amp, I didn’t get invoices from smiths but some people got a pleather wallet from xbs . Smiths is WU only, xbs does PayPal.

Well that’s one heck of a leap of faith!! Lol. Thanks much for the info. I’ll either pick up two Sanway 14s or bite the bullet on that xbs 20k, which would be wiser and more efficient.

Thanks all. Happy New Year.

Any links to XBS products or contacts?

Thanks Guys. Read most of the testing threads and I’ve arrived at the 20kq for the 4 HS24s. That will be plenty. My idea was to give the Amps a good amount of headroom and put limiters on them, but I think I’m going to be fine for my home use. For Live PA we would typically double headroom and set the limiters, but that’s for a very different application.

So that being said, looks like double 30a breakers for a 240 plug will be good? I saw someone said 50 but then later the thread indicated that it’s got a 120/60 (240/30) fuse on it, so this should be fine.

What’s typical time from order to delivery?

Thanks for all the help everyone.

NOTNYT - before I order, have any clones you want to part with? I’m across the sound in CT. We’ve actually spoken a couple years back.

google XBS audio, they have a website. They are also on ali.

DHL is one of the fastest from China apparently.
I went with FedEx and it took an extra week to get here.
YMMV

Keep in mind that Chinese holidays are starting up soon, so that section of the globe is going dark for a while.

Here is what a 20k does 1 of 4 channels @ 8-ohm into 2 LMS-18:

Here is what a 20k, 1 channel of 2-ohm into SAB-24 (7cuft net sealed), and 3 channels of 4-ohm LMS-18:

and 2 20k's, quad 2-ohm, and quad 4-ohm, also 1 14k dual 4-ohm, and also other amps and cones:

I have 200A @ 120V dedicated for just my HT room (2awg ~100ft, fed by 2 20kA pole transformers ~50ft, it pretty much NEVER sags below 115v, often just a rock solid 120V).
Each amp is on a dedicated 30A 120V breaker (10awg ~1ft), although 240V 30A would be more-ideal.
(Amp is easily changed to 240V with a few solder points.)

The 20k has twice as many power supplies as the 14k, so it is likely hitting higher powers long-term, the only downside is that it is also twice the power-density and so heat-management and fan-noise can be a contention. But it's almost half the price of 2 14k's from Sanway or Smiths. Is what it is...

I've pushed mine pretty hard, not to clipping though, no problems thus-far (about ~100 hours of use on the 20k's).
My 14k is a Sanway and is about 4 years old, no problems there either (1000's of hours.)
My iTech 8k is ~9 years old and is pushing close to 10000 hours I'd imagine, also no problems.

Many sessions of BassILoveU, EOT Intro, WOTW etc...

Who said switcher amps can't be reliable or are weak?

You probably know from posting on my thread, but I'll be doing the same as you but with only 3 channels of the 20k and (3) 24s. I am doing the dual 30amp 240v line and from what has been discussed, this should be plenty to get full power.

Indeed. Glad to hear you went all sealed. You will be happy with that and you can smooth and flatten them out nicely with some processing. Plus you will be able to pull out some single digit content. I’m on a cement slab, so unless I build a riser, my single digits are attenuated. Also, with sealed you can integrate other sealed boxes of various sizes with some processing very easily.

I’m pretty close to pulling the trigger on the 20k, I just tonight picked up the supplies for the sub panel, breakers, wires, and the outlets.

Hey anyone know what a Sanway DA2008 will pull for current consumption? I’ve got one I’ll be using for Volt 8 rears, backs, and 4 Atmos, just curious what it pulls for 1/8 content. They don’t publish any current info on it, just voltage. 200w/ch at 8ohms x8 with a Class D PS.

Question Brought my clone back up from the garage....

Hello All!!! Happy New Year!!!


I haven't touched my FP14000 in a while because, well, life got in the way and I never got around to figuring out why it went into protection when I pumped up the volume.


I dusted it off and I wanted to get back to using it for sub duty and was wondering if there was any guides somewhere in this thread that I can't find or somewhere else where I can measure and adjust the varistors and any other components on the board to make sure everything is adjusted correctly since I think that is the issue, that something is out of whack.

Is there somewhere I can look for help?
Any help is appreciated.

Which China manufacture build the amp? If Sanway, contact Johnson and let him know what issue you are having and he'll help with troubleshooting. Just do a search in this sub-forum for Johnson's contact info. If the amp was bought from one of the other China manufacturers, then reach out to the person that sold you the amp and let them know your issue.

I don't know what fuses the US models come with, but both my Sanway FP-13000 and the DP-10Q came with a
30A 240V fuse in a 10A socket.

I'd highly recommend switching the socket for a different one, I, for myself changed it for a 240v 16A socket with a 16A fuse.
The US models having a 10A fuse holder would be scandalous, don't burn your house down guys (I know, most of you have hundreds of hours on the amps already, but better be safe than sorry).

Which clone would be most appropriate for two dual 1-ohm SHS-24's (5kw RMS)? I have a dedicated 30A 240V circuit for it.

Ideally... probably 2 fp14k's, 1 channel driven on each. (Max RMS and Max cooling, most expensive, double the fans whizzing away, drives 4)
The next best option would be a fp20k on channels 1 and 3. (Worst cooling, comparable power, drives 4)
The 3rd best would be a bridged fp14k @ mono 4ohm. (least RMS [about half], cheapest option, drives 2)

The advantage of 2 fp14k's is more caps vs the fp20k, and double the fans and heatsink area.

A single fp14k still has good cooling, but is limited on RMS because of the lack of two power supplies that the dual 14k's or 20k would have...

I think what would REALLY be neat is a 2-ch version of the fp20k, basically a beefed up 14k with two power supplies, now THAT would be a beast! Imagine like 5kW x2 and 10kW x2 burst instead of 4.4 and 7. One can dream!

Yes, a 2-channel fp20k would make the decision easy! Really want to stick with a single amp, as I plan on adding additional subs and another amp to the rear of the theater room later on.

The low impedance of your load limits your options. Most amps won't run bridged at 2 ohms. I'd say look at speakerpower but their prices just jumped up even more :/

that is why. He is here. He was looking at a sp2-12000 and now with the price jump they are over 3k$. I can't sai i blame him as i would not want to spend that much either.

I looked at SP for my project this week. Brian has sold Speakerpower to a new owner. I had a very negative customer service experience with the company on the phone this week when I called about relief to the pricing for AVS members as Brian used to honor. Was told prices have been increased and you need to order 6+ to receive any relief. I stated this was a shame and I would not bring my business to SP, and that abruptly ended the call by the young man.

That being said I’ll be sticking with the FP20kq.

Hey Guys, with regard to purchasing the XBS FP20kq, what upgrades will I need to do for 240v service to a 60A (30/30) outlet, and ensure safe fusing (fuse holder and fuse as discussed above)? The plug will be a three conductor I assume, not 4?. Will this void the warranty?

Thx.

Was told prices have been increased and you need to order 6+ to receive any relief. I stated this was a shame and I would not bring my business to SP, and that abruptly ended the call by the young man.

That being said I’ll be sticking with the FP20kq.

I didn't realise there was special AVS pricing for SpeakerPower when Brian was CEO. When you say price relief was there a percentage discussed? There's no excuse for rudeness but when you said you won't be doing business with them there's really not much left to discuss?

Frankly it's not the possible failure rate of the clones that keep me away, because in terms of dollars per Watt there's no comparison. It's the fan noise. If that isn't a problem then go full speed ahead with the clones.

My amp rack is in a isolated closet, so fan noise isn’t an issue.

There were no worthwhile price breaks for avs members previously.

So you called them, asked to purchase their product for less than they're selling it for, were told no, and now you're badmouthing them? How is this poor customer service? Not trying to be offensive, but you sound a bit entitled here. Maybe reflect on that a bit.

You might want to poke @Mark Seaton and see if he can sell you a SpeakerPower amp, as he'd likely still be on OEM pricing. Not sure if that got bumped as well or not.

There’s fan mod info posted, the 14k can be tamed to dvr noise level and still have good airflow. These amps are designed for worst case cooling scenario, so ambient temps 90+ and high humidity.

It is China, there is no warranty

2 hots and 1 ground.

You may want to solder on a beefier power cord and you will most likely have to update the plug anyway because they typically come with a 15A 120V one.

I use the stock cord and plug haven't had any issues, that said, I don't beat up my amplifiers.

If you intend on modifying fans, the 14k should be the one you buy. The 20k needs all of the RPM's and CFM it can get at high load.

Not sure how long a clone would last if clipped at mono or dual 2-ohm, I would recommend staying below the -4db led if possible, lightly illuminating the -4db led AT MOST, or set the limiters to induce early clipping as recommend by XBS. Otherwise you might find out the hard way.

Hey BTH i would have to say this sounds like some very good recommendations. Also maybe i am missing something but 4 of the Hs-24 run off a 20q i cant imagine your neighbors not having a issue with this before you get to clipping. The remaining 4db al though there should probably be used as head room so as to not smoke the amp or melt the subs.

Hey thanks much for the info. All great advice. No, I won’t be running it anywhere near clip, EVER! Lol. ESP the Clones. So when you think that doubling the power only gets you a 3db gain, the headroom for cooling and safe operation is so much more of an asset than maybe 1.5 dB at the most. I plan on setting some conservative limiters.

And yes, my house and ears and neighbors (and wife) will outweigh the top end of the HS24s.

I’ve wired in the dual 30A (60 total) 240 outlet.

My only question that remains is what is required to covert the 20k to 240 from 120?

I will be putting a large gauge cordset and NEMA on it.

Anyone replace the fuse and holder on this one?

Thanks again all. I’ll be placing the order Monday. Hopefully won’t be held up for their extended vacation.
