What does it weigh? Any warranty offered?

Wow, 6" mounting depth is deep! Wonder if it would fit in my boxes??

Yes, this amp is definetly a big one. I believe the weight was mentioned at around 30-lbs and a one year warranty.

One way to overcome the DSP programming issue with DIY customers would be for SpeakerPower to implement a similar design to the OEM amp in the new SVS SB line. This amp also has DSP with 2 x PEQ and instead of having to be pre-programmed it has a small 2-line readout and a multifunction knob allowing the user to select the settings straight on the amp.

The Formosa allows the following through the on-amp interface:

Link to Formosa Plate Amp

Should be enough options for the average DIY'r, or they could offer an option sans DSP and allow people to use outboard DSP or their AVR.

Also, what happened with the Super Funky Wave amp?

Except that the Formosa amp seems to have at most 800 watts (with SVS having customed one to 1000 watts by changing numerous parts).

If they came up with a 2000 watt amp, now that would be nice. Or if the OEM that manufacturered the Seaton amps would build/sell bulk ... but it looks like a DSP capable amp at 2000 watts is far away for DIY.

Weight is 29lbs, No subsonic. The idea was to have bare bones power for the most flexible possible amplifier, and most cost effective. All the features one could want are readilly avialable in stand alone units, and or biult into AVR's, Mounting depth is not 6" that is the overall depth, the depth from the outside of the cabinet panel(when flush mounted) is 4.5", the heat sinks prodrude 1.5"(needs another inch or two of airspace.) The ac power cord ect all need nearly that much space from a wall anyways. If people would prefer we can very easily make the mounting depth 1/2" more, to 5" and then the Transformer could be inside the case.

If enough DIY'ers commit we can start the preorder, will run for one month. Shipping is expected one month after that. If not they will only be avialable in our finished products.

Just for reference the ED LT1300 is 5.5" mounting depth and 12"x12" plate, and it also weighs 29lbs(wieghed them both two min ago)

Nathan,

This is great news mate. We've been longing for a powerful plate amp for ages. Subsonic filter, who needs one. That's what the EQ.2 or reckhorn is for. What we want is good old fashion raw power.

Great mate.

Yeah, I wasn't saying use the Formosa, which as you note is 1/3rd the power, rather SpeakerPower implement a similar DSP input/adjustment through a small readout and control knob. According to a member who had spoken to them about offering the Torpedo to DIY/Retail, SpeakerPower stated they have avoided it because they don't want to have to deal with people wanting custom DSP programming, which I imagine is done through serial command currently. However, this issue would be solved if the amps had the ability to program the DSP right on the back (a la Formosa).

Part of the problem is physical space. The Speaker power amps are pretty "full" already. It is not so easy just to "add" a different DSP. Just redoing the metal work is a lot of work. A lot of pro people prefer not to have ANY controls on the back of the cabinet-that could get touched/changed by accident-therefore changing the performance of the cabinet.

I doungt there would be enough interest of the DIY to warrant a complete change in the size/layout etc to make it worthwhile to manufacturer.

Currently the DSP is accessed through a DB25 to "round" connector-like a keyboard connector-through a special convertor box.

The DSP is a "one way street". You cannot read anything that is in the amp-you can only dump programs into it. In fact if you hookup to a unit and turn it on-the internal program will be erased.

The programming is NOTHING like any other DSP I have ever used. Not at all intuitive.

How is this going to compare to TWO LT.1300's?

Why would you compare one of these vs 2 LT/1300s?

Its about twice the power of one LT/1300 and its only $700.

Unless you're saying you'd install two onto one enclosure? I.e., what is the difference between that and 1 of the Funky waves amps??

Why would ANYONE ask about the comparison of 2 competing products? Probably to determine value, availability, quality/performance comparisons, etc etc.....

Why is that a hard question? If the answer is one of the amps is 2x more powerful as 1 LT1300 at less than 2x the price and the same fidelity, then fine, that's the answser. But that's exactly WHY I asked the question. To find such things out.

4000 watts peak, means just that 4000 watts maximum peak power. Not sure what more to say about that, the 2000 watts rms is the most important figure anyways.

Compared to the LT1300 It is 2" larger in one direction, 1/2" shallower, the same weight, 1.55 times the cost, and 2000watts RMS.

Favelle,

Your question makes little sense, unless you plan on putting two plate amps onto the same subwoofer, which I don't think I've seen done.

If you've read the thread (it's all of 3 pages), you'll see this amp isn't even in production, so availability isn't exactly something we can compare. So commenting on its "fidelity/availability/quality/performance" of an amp that isn't even in production vs the LT1300 is impossible. All we know is that it's a 2000 watt plate amp, the dimensions, and some other things Nathan has mentioned in the last page.

I thought you might be looking for something else.

2 LT/1300 can not be bridged can they plus two of them mounted to one sub box isnt that easy.

The numbers were posted already 2000W vs 1000W, $700 vs $500.....not much else to say really and that was my original point.

I would buy a EP2500 before bothering with 2 LT/1300s. Considering that is a $300 vs $1000 choice and a no brainer for most.

The biggest problem I see with this is that (to me) this is only a EP2500 in the form of a plate amp... this thing still has 4 small whiny little fans, no crossover, phase control, eq, ect...

I've been wanting a powerful plate amp that has this power for years now, but to me a plate amp has to have it all... think any JL Audio plate amp or even a the partsexpress amp (assuming it could even put out what it says).

Like I said... if this is only a EP2500 slapped on a plate (which it is), then I'd rather buy a EP2500... or an even better pro amp if we're talking price.

Take the fans off this thing!

Or the opposite....if 2000W is more than I need, but I have TWO subs that would like 1000w each, then I have options. Maybe the 2000W amp can supply the power for TWO subs so that I don't have to buy two LT1300's....

In our tests it works without the fans but at a much reduced duty cycle, for movies only it would be fine, but with bass heavy music it heats up too much. The fans are quieter than a QSC PLX3602, and that is not a noisy amp.

We thought about adding variable subsonic, two band parametric eq and variable phase, but it would add $150-200.

Good point. If you need 1000W per sub and you want to run them separately for EQing/phase purposes then 2 LT1300s are a great choice.

If the two subs do not require individual phase adjustment you could wire them together and run them off one bigger amp. The only question though would be the driver impedance and the summed impedance after wiring.

Agree re: the fans. I modded my 5050 with a fan from Digi-Key that was rated at 30db, much lower than the stock unit, but still too loud...not sure how it would compare to a 3602, but I'd imagine the modded fan is similar.

Yeah, I would have to plan ahead. I guess I would need 1ohm drivers? And if both corner-loaded in the same corner, they would also be the same phase, right?

The fans were already as quiet as the quietest pro amps, but we found fans with the same air flow rating, but 12db lower noise rating. they are only a few cents more, so we will be using them in the production run.

The DIY preorder dosnt have many commited buyers yet, time is running low.

One week left to get on the list for a DIY preorder.

We got the db readings on the new fans,

45dbA @1' High speed, noise floor 36dbA
On low speed, with a noise floor of 36dbA there was no reading at 1', had to be 2.5" from fans to read 40dbA.

Great feature set, but at what cost?

These amps clearly are not the same that were being touted in this thread originally.

I doubt the 2.4K version listed on Funk's site is remotely close to $700.
