While being at it, I made dollys for the speakers. These beast are heavy...

As stated at the beginning of this thread, the short term objective was to build two (or four) big monitors JIT for a demo today held at the company's listening room. (This was a private initiative of mine, and the construction entirely an after-hours activity, albeit at the company's premises.)

Here I am, cutting MDF for the throat plates. (Yes, my colleagues are used to my eccentric behaviour )

Even though most drivers were not even mounted, I rolled in the cabinets just to show them. They are indeed a nice piece of conversation, also in silent mode

Sorry about the bad pic (I've been busy building speakers you know...) ETA for fire up is Friday.

Looks great....

Keep us posted...

Hi Fredrik,

Nice.

Just curious of the inside dimensions of the box containing the 2122 ?

Thanks,
Mike

Well, you're obviously a mad man LFH,
but what big beautiful monsters you have made!

Thanks guys

I figure the "dog house" is large enough for a Grand Danois (net volume is 72 l) The idea is to adjust the volume by means of internal walls. I have to measure the FR to determine the effect of the baffle and the big horn before making any decisions on where to cross over to the woofer and how to tune the mid-bass accordingly. (I don't expect just copying the 434x design will do the trick.)

So how did this demo turn out finally?

Modular speakers with smith horns - more info, please!

Hi Ifh,

adding some blocks of styrofoam to eat up unneeded volume should be easier than "to adjust the volume by means of internal walls".

Did the prototype ever make it to fruition?

Ron sends....

[Moving over my backlog]

Well, yes and no: Currently the bass modules are used as subs in a surround monitor setup. Running four 2231:s in a small control room is quite nice!

To finalize the rest of the project is on my list of things to do before I die...

Ruediger, that's a good idea. I'll probably add some non-compressible, non-resonant stuff to eat the excess volume, like you suggest, at least to begin with.

How was that demo?
I know it was 4 years ago, but please tell us the end of that story
