Since I'm building two, add 6dB to this graph and that's what I'm looking at for my room! biggrin.gif

This model/build looks very intimidating!!. I hope you have access to a huge workshop and a lot of very strong friends to help move those beasts around. Not sure I am up to such a task so I think I will have to stick with individual boxes.

Wait, are you planing on keeping those XS30s in your system? I am quite certain they will be overpowered by the Martys

Man, you are soooo lucky to have access to Chaluga's workshop. I've seen pictures of it---looks like an awesome place to build stuff

No I'm selling one and putting the other one upstairs in my living room setup.

Just watching American horror story tv show. No tv show has as much bass below 30hz. Plenty of bass at 20-25hz. Five second deep bass passage . Weird show but sounds great.

Second post in this thread is now updated.

We are now committed to 14 of the needed 40 drivers.

Still need 26 for the group buy pricing to happen.


edit: bolded to draw a wee-bit more attention to where the group buy stands at this moment.rolleyes.gif

Oh, and with the exception of my surround speakers, everything else is DIY. And I expect rectify that by building two smaller DIYers for surrounds as soon as I can find the time.

Yes, a UXL will rock in a sealed enclosure.

Yes, a UXL will rock in a Marty sub.

So, atabea, will it be one or two UXL we can put you down for?

Copy that, Spider.
You are number 15 of 40.

Come on folks, let's get these commitments in.

Have to hit 40.

Archaea...I get the feeling you cover all of your bases...NOW are you ready for those four? biggrin.gif

You would have us just about half-way there.

So if/when the 40 is reached, is that it? No more drivers available?

Did you hear back, from Mark, if the group buy size can be increased? If no more than 40 available - then when one guy who wants 16 jumps in the group buy is effectively over! eek.gif
post #135 of 1320
As I understood, 40 drivers are the minimum for reaching the GB price. I have a hard time believing Mark is saying no to selling more then the 40 drivers.

Well...right now, we only have 15 commitments...even another 16 only puts us at 31 right now. rolleyes.gif...As jbrown said earlier, let's concentrate on 40.

The price break and reasonable production time were discussed at a quantity of 40. One of the advantages of this Group Buy was staying very close to a given production quantity so Mark could deliver the drivers within a reasonable time frame. It certainly s*cks to order something, be told it will be delivered by a certain date, and then find out it will be another 4-6 weeks longer than you thought. He has stated that he could reasonably start to deliver 40 on February 2 if we place our paid orders in early January.

We were certainly not limited to 40, but a greater quantity might delay Mark's acquisition of production materials and certainly take more of his time.

I am waiting to hear back from Mark. My request for 60+ pricing had two aspects to it:

1. what would the pricing be at 60+ drivers?

2. would he be able to accommodate production of 60+ drivers within our time frame?

Having said that, member auburn has committed to 16 drivers IF the price were to be lowered to $375 per driver. I also know that auburn has kindly stated he would not mind if his drivers were put at the end of the production run if that would help with things not being delayed. But if $375 is not offered, that order of 16 is not there.

Member ChopShop also voiced interest in ordering 16 drivers, but his target price was more nebulous. Between Chop and auburn, there could be 32 drivers, 16 drivers, or zero depending.

It would be nice freakin' awesome to hit auburn's target price, know that he and Chop were good for 32 total on top of the existing 15 and we only needed 13 more for Mark to have 60 drivers sold. And we all know it would go over 60 at that price point! Let's keep our fingers crossed?biggrin.gif

Just heard back from Mark seconds ago.

The 40-piece price of $410 shipped for each is the best he can do. He lowered the price from $530 to $410 for us...that's about -23% and not chump change. Still a great deal!
Have not seen this much performance offered on a current in-production driver for that price anywhere else.

If any Group Buy people want to commit to 16 at a time, the drivers would be shipped on a skid. Shipping would probably be cheaper that way; and the savings would be passed on to them.

Mark still needs to double-check materials to see if there are sufficient quantities to fulfill a quantity much greater than 40.


We need 25 more commitments! biggrin.gif

Thanks, auburn...you have a PM.
post #140 of 1320
I'll ask again, how far off the mark would an EP-2500 be for two of these in the sealed 4ft flat packs?

I'm seriously thinking of four but if I had to buy a IPR2 7500 DSP because my EP's are not enough, that changes my bottom line about a thousand bucks.

Good question. I'd be in for one if it can. smile.gif

H8...hopefully someone solidly "in the know" will be able to chime in here.

Well...in light of the $410 being confirmed and several PMs asking if we could push the order time-frame out just a little further post-holiday...the deadline for getting up to 40 drivers has been extended by 2 weeks.

If waiting till mid-February rather than beginning "of February" throws someone that has already committed way off and they wish to bow out at this time, please let me know with a post in this thread.


edit: added "of February"

post #145 of 1320
Hello All,

I have a dual opposed 230L Dayton RSS460-4 18 currently.

Based on the response to these two questions - I will probably take two.

1 - Can Mark please confirm what is the shipping weight in metric for a single unit in the box? (Ideally needs to be less than 32kg)
2 - Can anyone confirm if the UXL is a straight drop in for the Dayton? They both state a cut-out of 424mm.

Thanks.

Will ask Mark about dimension/specs and post later.

A single ep2500 for two of these would be okay for most people. If you're the type that pushes it to the max all the time then you'll find yourself lacking power most definitely. Based off your single post here I can not tell you much more as I have no idea what the playback conditions are like for you.

I would recommend using an ep2500 per driver or some form of amplifier upgrade for the long run though you could get by with a single.



So you can see there is an overall 6dB left on the table (full bandwidth) which runs ~2,400w total. At some point you should upgrade from a single ep2500 if that's the case.

1- I'm pretty sure the driver itself is 65lbs. With the box and everything it has to be around 70lbs (32kg).
2- Short answer - yes, it is. I have a UXL-18 in a 4cu ft flat pack from DIYSoundGroup. I did have to remove the rubber gasket, though you can easily substitute some foam tape for it.



blah450- mark me down for one for when my tax return comes in.

I have been considering dual Rythmik FV15HPs, but lately I have been thinking of going the DIY route. This option seems particularly suited for my open basement HT (8000CF). Can someone comment on a few concerns:

1. How would dual sealed UXL-18s using the DIYSoungroup flat pack measure compared to the dual Rythmik FV15HPs?

2. The UXL site lists the dimensions for building a ported enclosure with a 2 inch slot port at the bottom. Does anybody have any experience building something like this? How would this ported design compare to the performance of the Rythmiks?

3. If I did build the ported enclosures, can someone recommend which amp would be appropriate? Would seperate amps be required?

Sorry I seem to circle all my comparisons back to the Rythmiks, but it seems to be the top dog of commercial options - especially for such a large space as I have. I am hoping this DIY option will give me better performance at the same (or slightly lower) pricepoint for my HT.
