The problem is: I'm in Norway! Norway is not in the EU, so 25 % tax on top plus expensive shipping from Denmark to NO and from NO to the US

Are you unable to order directly off the site and have shipping by sea organized? I'd do it for you as a gesture (ie without added cost) if there is a way to do it, but I'm not sure how. I've never shipped anything this big to the US and I have no idea what shipping would be, but probably not cheap.

We can see if Jetcarrier.com is willing to ship to the US. They do ship from the US, but not sure about the other way. I think they have a port in DK too. The best and cheapest way would probably be to order from the site, have it sent to Jetcarrier, then it would go directly from DK to the US. Jetcarrier is a freight forwarder (we often use it in Scandinavia to get big items shipped by sea) has offices in the US. You should probably give them a call to hear if it's possible and your alternatives from the US port.

Edit: If you are wondering about any of the words on the site, I can explain, Norwegian and Danish are very similar languages. You should have no trouble getting replies in English from the site or Jetcarrier, we have English in school from very early on here in Scandinavia.

Edit2: If you're unable to make it happen through Jetcarrier, I'm sure there are alternatives we just have to find them. I'm looking at the national postal service in Denmark now, their site is also in English: http://www.postdanmark.dk/en/Pages/home.aspx Maybe they can do sea freight?

Edit3: http://www.leman.dk/flx/dk/dansk/forsiden/ might do it from DK.

Edit4: If you decide to call Jetcarrier and they're not able to ship from DK to the US, then be sure to ask them for alternatives. They should know.

And don't hesitate to ask me anything.

matt, have you experimented with something like this:

linear phase is part of the secret sauce in jbl's totl m2 studio monitor.


that's about the only thing that i can think of that may offer an improvement. of course, some final eq based on baffle wall reinforcement is likely necessary, but that would be the case with all speakers.


do the speakers do anything 'wrong' that you have been able to detect?
That MiniDsp software plug-in for implementing FIR filters looks very interesting! Could the MiniShark + this plug-in mentioned in Johns post be used as an active crossover device with linear phase control through the FIR filters? Isn't that the main benefit of FIR filters in that it can keep the phase almost perfectly linear throughout the frequency band?

Would the MiniShark -with this plugin be all that much better when used as a 2-way active crossover as compared to the MiniDsp 2.by 4?

If one wanted to use the MiniShark as an active crossover with the FIR filter software option, how in the heck would you setup the phase response through the FIR filters, as compared to using just a basic balanced MiniDsp 2 by 4 with HPF & LPF slopes and various crossover options? (Ie: LR, BW, ect...)

you might find this walkthrough (from the jriver forum), on how to use RePhase, gives some insight on that question

The linear phase stuff looks cool, I have not played with any of that myself. It seems as though you would need to build your own I2S to analog output device in order to do more then a 2 channel active system using the linear phase crossovers. The other option is to stick the miniShark or OpenDRC in front of the miniDSP and just correct the phase that way, but you would need 1 box for every 2 speakers.

What would the cost be on something like that?

It looks like miniDSP has some new additions coming in the line for 2015.

It's baaaaaaaaackk.....well, typical me, I sell all the parts and decide to start over...please keep the laughter to a minimum gentlemen


After a lot of thought, I just can't imagine a speaker sounding better than what I think the full potential of this build was. I have decided however, the quad version is not the starting point, the dual is. Full active and dual 15s....no desire to go full range, just ridiculously clean ear shattering output capable of 60hz up without compromise. More than likely ported and right on the line of the original dual woofer version, but as I said, fully active. I truly think that's the difference maker in this one, especially with the use of the 4594. I haven't ruled out other woofers or cd's, but I am pretty stuck on the original combo I think. I still have a few TDs too, so that makes life a bit easier. Any new thoughts are more than welcome.

Are there any other CDs out there like the BMS 4594 that are in the same class and price range? You know, a CD similar to what's in the JBL M2 but without the price tag.

Thanks man! Should be much quicker this time...I actually still have the original cabinets for the dual and the caps for the quad version, so basically just xover play now.

Not sure...Al from Usspeaker says the Radian 950Be is better all around, but I haven't had the opportunity to try it yet...maybe he'd like to lend one out for testing

Yeah, anyone who knows me well will tell you I'm a spaz...


Don't worry, I'd imagine that 16HSTs will equal them in output and allow for even more 1/4 point placement

So did you ever have a quad 15 put together or just a dual?

I am only doing dual 8's but I keep thinking about making my speaker bi amp-able. But thats only because the 8's can take so much more than my AVR can put out. BUT fully active would be fun if I had a preamp to start with. So fully active for you sounds like the best way to go to me.

Quad was up and running too...there were a few issues, but it would be perfectly tweakable too. I just think that although I'd love to have over over overkill, the dual version will reach levels far beyond need, even for a nut job like me. My original concern and reason for going quad was to be sure that we were always cruising along well below the limits of the system, even when really pushing it. I think the dual will accomplish this quite easily based on my experiences.

Glad to see you reviving the project! They were an awesome sight at the GTG .

That Radian 950Be must be pretty awesome if better all around than the M2 driver. I definitely want to hear it when you get it! Exciting man!!!

Didn't mean better than the M2 drive Mark, better than the 4594...truth be told I don't even know what driver the M2 uses...haven't looked at all.

Well, well....JBL D2430K. Kind of expensive at almost 2k a piece, but readily available around 500 or so on the used market. If in good condition, that would make it less expensive than the 4594 BMS

There ya go. But you're way outside my knowledge base when it comes to matching horns to drivers and such. I would suspect that is probably rather important too.

My basic understanding is that it's similar in the respect that it's a dual ring radiator, but the JBL uses two diaphragms...not sure yet how they interact (push/pull,etc)..just started the research.

The proper waveguide will matter a great deal...I'm sure we can scrounge up something that will have the proper angle and pattern....the mounting plate should be easy as basically anything can be fabricated. In all honesty, I'd prob rather go with the 4594nd..get them done and enjoy, and them maybe grab a 2430 and experiment with wg's...God knows it will take me forever to try to get that right

To save reading the whole thread would you mind telling the inquiring minds what you are actually building.

We had already built a theater tower using the seos24 BMS 4594 cd and quad td15m woofers. It was pretty much a first run at one of gorillas gtg. It need some tweaking, which we were doing, and when some house issues cane up I scrapped everything. Things are cool now but for mobility sake (gtgs) and what not, I'm going to do the original dual woofer version. May told me in the beginning that the dual woofer would have more than enough headroom to coast along on most anything, but I just had to build the biggest thing in the diy section cause I'm a dumba $$ I am thinking about a jump to the td18 woofers but some of the magic lies in that 15m I think, so I'm hesitant

Still liked the idea of the quad 12'd and SEOS 24. But thats just me. Should be doing a dual 10" side by side under a SEOS 18 soon. We'll see how I go from there.
