Hi Cal, how are you crossing over from the 500 to 800? I have an idea that needs more thought. Something like load sharing.

Also, what's that up in the top left in thes last pic?

You don't have to wait for spring, it's summer over here.

Cheers,

Geoff

Part of a kitchen cabinet set . That is the lower corner cupboard I have stuck up on the wall. It's where I keep my stash...

...of caps coils and resistors.

Thanks buddy. Strong winds and rain mixed with snow here. You really cheer me up.

The lower is a Selenium D250-X on the 511 horn and a Selenium D205Ti on the 811. The woofer is a Selenium WPU-1507-QCF.

I knew that this isn't KH .......just because this days my head is full with KH papers and plans (just thinking...thinking....)

regarding Selenium.....there is one on pic in post No.15 ......hehe,but dunno number from top of my head .......used as supertweet,temporary with APT80's plastic horn,just for better dispersion.
crossed with two para 0,47UF VitQ in line and pretty attenuated.

Jeez, I just came inside for the back yard where I was sitting in the shade reading a book about Australia and drinking iced tea.
Lovely day, here. The meteor shower last night was wonderfull.

Ah ha, I was supposed to stick the D210s on the 811s to have a listen, never did. How are the D205s?

FYI - the RCA cabinet in that photo is one of the ones I owned and used with my 1803s. Boyd drove 1500 miles to Kansas to pick them up from me.

Greets!

We seem to have a 'failure to communicate'. I'm not referring to its CD horn HF roll-off, but the mass quantities of comb filtering going on with increasing frequency between the cells, which no amount of electrical EQ can correct other than a low XO point and/or steep slope, though open cell foam inserted in the outer cells to roll off their HF will help somewhat.

Well, mine for one when it was all together/functioning. I much prefer reproducing all the dynamics a recording has to offer Vs the euphonic clipping of a typical low power tube amp, or worse, the not so euphonic typical SS clipping ckt.. Even with an H.E. system it takes a lot more than 'flea' power to reproduce the +30 dB transients on some CDs.

W-bins do make big sound, but back when I had a big rig I didn't have the luxury of steep digital XOs/TD, so stuck with the truncated, wide BW front loaded 210s. Anyway, nice to see them preserved rather than chainsawed for easy loading into a dumpster like has been the fate of most of these 'dinosaurs'.

Yeah, we're in the midst of an 'Indian Summer' that they predict will last for another 10 days or so, with mostly sunny skies and highs in the low 70s. No tree shade though, I raked up the last of the leaves/cleaned out the gutters yesterday.

Must be nice, 'Hotlanta' is so lit up at night that I haven't seen much of the night sky around here since the late '50s.
