Statement II speaker build

[greg90]

Has anyone on here built a set of Statment I or II speakers designed by Curt Campbell and Jim Holtz? Have some crossover to terminal connection questions
Thank you

I haven't seen any mention of it, although there could be someone around that has.

Did you start a build already, or just considering it for now?

I’ve been thinking about it for a couple months and reached out to Jim Campbell and he was pretty helpful and recommended a different 4 inch driver and gave me detailed instructions for what parts to change in the crossover. It’ll be my next winter/spring project. It’s a three-way set up. The 8 inch woofers are wired in parallel down to four ohms. The 4inch mids are the same. And it’s a 7 ohm single tweeter if I looked at it right. And maybe I’m thinking about it wrong in my head, but if all those get powered by one source it’ll have a really low impedance assuming all the + and - from
each crossover go to the same + and - speaker terminal.

That's a good question. I've never built a speaker with a crossover... maybe someone will know.

This place is full of knowledgeable people. Something will come along

Have you thought about tri-amping? With active crossover you can experiment and really dial it in,

I was hoping to either run a mono amp on each side or get a 2 channel amp. My end goal is kind of like this wiim ultra-geshelli dac-hypex two channel or two fosi mono’s just trying to keep it simple for my first dedicated 2 channel build and maybe upgrade in the future. But I’m open to suggestions. If I’m understanding I’d have a dsp feeding 6 different amp channels?

I use a Xilica 4080 crossover for a 3 way biamp setup. I run my crossover close to my speakers and run xlrs to my rack. I have a minidsp ddr88a that I will be placing in front (signal wise) of my xilica crossover...this way I can run just 2 channels of dsp to my xilica, and the remaining inputs and outputs In the minidsp will be used for my surrounds and height channels.

I use the same speakers for my left and right channels for my AVP and my Athena stereo preamp. I Am running 2 pairs of the Fosi V3 Monoblocks and a pair of plate amps for my folded bass horns. I used to run Icepower amp modules and I kept seeing all the hype about the Fosi v3 Monos that I figured I would give them a try. I put them on my compression drivers (500hz on up) first and WOW, the clarity was so much better. A friend suggested I try them on my mids (100hz-500hz)...So I ordered and 2nd pair (this time with the 5amp bricks. When I got them in I took the 5amp power bricks and ran them on the compression drivers and the 10amp on the mids. The second pair gave me exactly what I liked about the 1st pair of v3 monos...clarity, dead silence between tracks and perfect synergy with my compression drivers, mids and my bass horns.

I had to put this together in my head a little bit. New to home audio still. So are you setting crossovers using your xilica and using your dsp for more signal outputs and tuning?

Yes... I am dialing in with a microphone at 1m from my left channel and then from my right channel at 1m. Then I have the 8 channel minidsp (using the left and right channels going to my xilica), and the remaining 6 channels for my surrounds and height channels. I currently have only the Xilica hooked up as I am installing different 15" drivers for the mids bass (I need to retune with the change), and my rear channels are awaiting some stands (have not been tuned). I hope to be finishing up with all 4 channels being tuned from 1m and then tune all 8 channels with Dirac from the mlp.

You’re really going to have that dialed. That’s awesome. Do you use this for HT and have a stereo mode for music or what do you use this setup for the most?

I have a Marantz 8805a for HT and a Denafrips Athena for stereo. I purchased a little box that I plug the left and right channel outputs into, and then the left and right channel outputs go to the Xilica. I have the box setup to where the Athena is default (amps are signal sensing for turn on and turn off) for switching which source goes to the Xilica. Currently I am only running left and right channels...so serious listening goes to the Athena and watching TV (no surrounds, or heights) I use the Marantz. Works out nicely.

Very nice. I’m going to do some more research now. I appreciate the input. Looks like there’s good options out there

If you look around you can get a nice crossover used for about $500 or less. I have a 2nd active crossover... Yamaha pro crossover that was highly recommended. My Xikica I picked up for $800 new and now I have seen them going for over $2k used.
