Center started for Ruination and Levitation speakers

[Brewski]

I started work on the center channel speaker I'll be running with the Ruinations and the Levitations. The center channel is going to use 2 Peerless 835004 woofers, 1 Fountek FW146 as a mid and a Vifa DX25 tweeter. I've not picked out a stone brewery name for it yet but I'll be looking for one shortly.

Wow, looks great Brewski! Now you got me thinking...

You've a -5dB step in a critical midband range there. Being a center, and mostly dialog usage, I'd opt for less of a BBC dip, and if anything some accentuation in the 700-2k range for speech.

I think you'll be better off with the levitation center mods we were talking about and it would be les costly over all. I could sim another version with the BC25 as the tweeter though if you'd want to see what it would look like. The tricky part will be finding more of the 835004 woofers but I think someone found some that were for sale for around 25.00 each.

Yeah the crossover is still a work in progress here's the latest sim. The 146 has a bit of a dip at about 1400 hz that I'll need to work around.

Another possible issue is the impedance bump from the DX25 there. It may sound nasal without some attention. That sim looks a LOT better too.

Out of curiosity, is there any reason you crossed from the woofers to the mid so high?

My guess is the bandpass gain required to fill in the dip also required a narrower xover range. As long as he's below 1kHz, this horizontal W-T/M-W will be just fine.

I'll probably try it without the attenuation first since it looks like its slope is third order at 2800 hz until it gets to 20 dbs down. Looking at the tweeters impedance plot with the crossover in place the tweeter's curve is about 10 omhs above the baseline impedance plot.

Yeah Wolf nailed the reason I'm trying to help fill in the dip at 1400 hz.

To get the M->T phase better, I'd up da tweeter one order.

Yay, me! :rolleyes:

Re: Center started for Ruination and Levitation speakers

Here you go Wolf think that looks a little better crossover wise.

I may be interested in parting with 4 of those Peerless 6.5"s.

That definitely looks like a wiener! :D
