  1. Burp power will depend on the soft parts used & the frequency -- in the right application 20k+ for burps could be seen.

    We had some guys in Russia do 20k burps on an NS v.2 before... I've done ~8-9k burps on an SA-18 for that matter :)

    As far as RMS... we rate our TEAM for 5000-watts RMS and it has a larger coil. Although -- having such a strong motor these will move more per watt of input (so more air cooling per watt applied) -- so thermal dissipation will be more efficient. I had considered just putting "variable" for RMS power as each one will be built to suit the application it is being used for.

  2. no doubt i would like the SCV line.. i was just going by your post saying they would be cheaper per watt but actually they cost just about the same.. still beast amps that i would like to get my hands on.. that SCV 6000 is what im interested on.. i really need a 5k amp but looks like it goes from 4k to 6k

    They are cheaper per watt -- as each one gains ~15% power and none of them cost 15% more. Savings is 2-10% per wattage depending on the model.

  3. I notice above that WoofersEtc pricing on the OLD models is actually above our original MAP -- they do own the last remaining stock of many older models so they have adjusted their pricing to reflect that (obviously they own the inventory so they can charge more than MAP -- just not less). This also applies to some SCV models that we are sold out of at our warehouse.

    ----------

    In any even these are the ACTUAL rates of change of pricing (below) -- and at each level there is an ACTUAL ~15% gain in power on 12v systems. The gain in power compared to cost change is best on the bigger models, naturally.

    Here is the background -- I did a large analysis of every part of our business starting late 2013 through early 2014... spending several months on going over every expense, every aspect of fixed overhead, dealer program levels, dealer points, etc, etc... and arrived at the fact that the SAZ line wasn't working out in terms of ROI for us as a company or for many of our B&M dealers. Additionally as we have grown to more and more of a B&M dealer company -- a smaller % of our customers now take advatange of the 19v stability offered by the SAZ line.

    So it was either cut the whole thing (e.g. Cut all Korean amplifiers) -- or rework the entire line to make it work for everyone -- at that point the SCV line came about after much deliberation and brain-storming; they are now where they need to be for us, our dealers, *AND* the customer actually gets more 12v power for their money, in a smaller package per watt, rather than just a price increase for the same thing. To me -- that is a win-win situation... customers and dealers alike have really been enjoying the new SCV amps.

  4. The SAZ-5000D & the 6000D cost almost exactly the same amount -- the 6000D produces quite a bit more power on 12v than the 5000D. They aren't just a re-label ; things have been re-worked on the boards. It's hard to tell in the photos -- but alot of that is in the transformer windings; you will notice they are not identical from amp to amp in the photos above (since they are actual photos of each model). In this specific case (6000D) I was able to get some cost concessions from the factory so this model changed very little in price.

    For instance... the SCV-6000D is now several tenths louder than an NS-1 v.2 on a 12v system. So it's actually an even better performer on 12v than our largest model now.

    For a given board layout they are a bit more expensive than in the past ; but per actual wattage on 12v they are cheaper.

    I haven't released the actual Dyno figures on the old SAZ line since they are discontinued (you cannot compare old clamp tests to the Dyno) -- but the SCV line are all significantly more powerful on a 12v system than the counterpart SAZ boards. Typically around 15% more powerful at normal voltages; with an even larger difference in more extreme voltage drop situations (e.g. most real cars that don't hold 13+ volts).

    Given an oppurtunity I may do a complete round-up down the line as a reference... will have to round up some older models as we've sold them all out for the most part.

  5. It is my opinion that most folks who believe they lacked top-end ran them ported.

    I owned & ran a Brahma 15" in a sealed enclosure in my vehicle for some time and had no such observation of the top-end. I even did a test pairing it with a tweeter and a passive crossover and mid-range was also fairly impressive considering it was a sub-woofer.

    ----------

    It's the same reason people think our X, Z v.4, etc lack top-end... the lack of parameter shift over stroke :

    http://www.diysubwoofers.org/misc/dumax/details/adire_audio_brahma_12.pdf

    KMS vs. X is very similar to our new platform drivers except it is not over as wide of a stroke range (naturally... as they used an 8" spider and a standard frame) -- but in it's range it is MEGA flat.

    BL vs. X is ALSO very linear thanks to XBL technology -- this further reduces QTS shift over stroke -- even beyond our stuff.

    ----------

    Now go check my article about the new platform sound :

  6. Hey guys,

    This is a project I've been working on for a while... it's origins date back to 2009 with my unfinished 4" coil Neo design (some may remember it) :

    http://www.caraudioclassifieds.org/forum/sundown-audio/19945-proto-neo-4-motor.html

    I put the whole thing on hold to concentrate more on things that would really grow the company & our dealer base. That being said... fast forward 5 years now and I have the opportunity and ability to work on this again.

    As far back as 2009 I knew I wanted to go after my Neo SPL design with a 4" coil -- so I did that again. This time I went for a good bit more Neo and a different / unique design :

    So this is my first prototype / first fully completed Neo prototype. This may not be the 100% final version but I think it's close. I should have it in my hands early on in January for testing.

    Few quick details that I am releasing now...

    1) 4" voice coil

    2) 16 slugs of N42H Neo (N48H was a large cost increase with almost no increase in flux)

    3) Will be sold in 12s, 15s, and 18s

    4) Pricing is TBA as I go over all the final costs of the motor... certainly not cheap; the motor itself costs about as much as 7 pcs Z v.4 motors based on my early estimates.

    5) It is mated to a 10" frame in the photo for size reference; but I don't currently have plans to make them as 10s

    6) Motor weight is ~70 lbs... overall external size is almost identical to a Z v.3 motor.

    That is about it for now... except for a quick photo of my Neo chunks :

    neo%20magnet-2.jpg

    These look a little rough as they were cut into shape; when we end up doing production we'll tool the exact size/shape we end up with so they'll look perfect.

  7. I just bought a used scv 2000 it plays but it only playing when the gain is almost max my installer saying that it shouldn't even have to be half way to play right it sounds good but he's saying that it should be alot better how much does it cost to repair the amp

    I would first check your signal -- check voltage on the RCA cable.

    Also make sure the LPF and Subsonic filters are set correctly.

  8. The X, Z v.4, and NS v.3 all use the new frame platform & they all use the "Mega Roll" surround standard and the "linear" spider standard (SPL surround & SPL spiders are options for all). From this point the differences kick in on the rest of the driver :

    X :

    Power - 1250 RMS

    Coil - 60mm long, 4-layer round CCAW wire

    Spider - 4 layers, double leads

    Motor - 66mm x 190mm magnet stack, 15mm thick top plate

    Z v.4 :

    Power - 1750 RMS

    Coil - 65mm long, 8-layer flat Aluminum wire

    Spider - 5 layers, double leads

    Motor - 75mm x 220mm magnet stack, 30mm thick top plate

    NS v.3 :

    Power - 2500 RMS

    Coil - 80mm long, 4-layer flat Aluminum wire

    Spider - 6 layers, triple leads

    Motor - 80mm x 250mm magnet stack, 45mm thick top plate

    Motor force scales up as you go... usually gaining ~1dB or so at equal power per step & more maximum output due to more excursion.
