In the nearest future I will have two more poweramps, 4 in total (Crown K2, HH V800 MOSFET, BGW 750C and Krell KSA50Mk2) and was thinking about turning the 4343's to active with something like MiniDSP 4x10.
I'm wondering - is such a thing possible as the stock 3143 has quite a lot gimmicks built in to make the 4343 work properly I guess?
A small bump on this one, still looking for info
That's quite the mix of amps , HH V800 , lovely big lump.
Thing with the DSP is you can accomplish in minutes what would take you weeks to organize using passive.
Make the 4343 work properly?Originally Posted by martin2395
To me, that's a strange question, as you already have lots of high-end gear to match 4343...
Work properly as "maintain the right xover points, slopes and AFAIK there is some equalization added too"
@macaroonie,
It would be just a test setup, then I could for example buy another Krell 50 to use it on the 2441's and 2405's.
I have no clue what's the deal with the V800 but man that thing sounds good! It's only a pity that every couple of minutes the cooling fan kicks in for like 45 seconds.
Hi Martin,
based on my own experience I would like to recommend this DSP:

You will have 30 days time to make your own practice -and I think you will be surprised!

I forgot macaroonie's tip - leave the comp. driver and the slot on passive network and the 2123 and 2235 active.
Then a Driverack PA2 would be amazing for a total noob like me ;D I'm not sure how easy to use the Xilica or XTA gear is?
DSP would be nice so I can, for example load 4355's settings - 290Hz and 1200Hz xover freqs.
Thing is , you can set almost any frequency , filter , delay , everything.
Hugely flexible , have a play with the software link i sent you. you'll get into it after a while.

Martin,
of course it is not sooo easy to work with a Xilica DSP. Every (new) user need more or less time to understand the software and how it works.
Fortunely the european importer in also in Holland just accross the Ijsselmeer. If you have a problem you can ask them or other users.
I'm using the Xilica XP 3060 for my 2-way surround speakers with JBL 2426/2344A and 10" Visaton-Bass (GF250). There is a huge difference between the active version of these "small 4430" and the speakers in the past using the passive network with JBL-parts.

I see. By the way, how does 2123H sound on your 4343?
4343's original mid-range drivers are 2121, and some say 2123H is NOT interchangeable with 2121 because of their different voice coil winding depth. Given that 4343's soft spot is this mid-range, however, I feel strongly tempted to use 2122 or 2123H...
Actually the Xilica XP 4080 would work very well for you since you have 4 power amps on hand. Also splitting the original 4343 x/o to leave just the HF and UHF is physically very tricky. You would have to have the network diagram and then extrapolate the connections that you need. I did it for 4315a and it took ages to work it all out.
Remember that if you are doing all this ( and it's worth it ) that the HF and UHF will need protection caps in series.
Values here
I forgot about those caps
In that case I might just aswell order a new hf/uhf network rather dan butchering the original 3143's.
I tried the V800 today on the JBL's but it's a nope. It's just not refined enough voor HF duty, not harsh but grainy.
Partially it's the X-over's fault as it clearly adds some contour to the sound.
Do the Xilica's have their own sound signature? And what about XTA 224 or 226, they are a bit dated I guess?
To be honest, when it comes to digital stuff I prefer to keep it as modern as possible.
I've used both XTA226 and 224-currently a 224 is on duty with my K2 clones(ME150H/2452/TRUEXTENT/H9800 horn).
The XTA's sound transparent, are powerful and have a nice 'analogue' top end free of any digital glare. They have a particularly good reputation for good reason.
I'd swap them for a Lake but that's all.
Since it was the easiest to get I decided to give the PA2 a go, I wonder if this is right (yes i know that the slope should be 12dB):
Then the Highass for the High section is also at 300Hz. I wonder if you can tweak this stuff "on the fly" to directly hear what the difference is
Likely, you can on the 260 and 4800.Since it was the easiest to get I decided to give the PA2 a go,...I wonder if you can tweak this stuff "on the fly" to directly hear what the difference is
If we knew what the hell we were doing, we wouldn't call it research would we.
