Beta tester wanted for lightweight 2x12

Sandpoint, was there a couple years ago, eeek 2004! County seat of Bonner County. Yes named after a relative. I totally understand why the people who live there love it... Lake Pend Oreille was pretty cool. My buddy from Florida and I were on a road trip. Went up to Vancouver Island to Port Alberni and then drove across BC and entered into the US in eastern Washington. Then cut down Idaho to I-90. Met a beautiful gal of my age working at a 7-11 in Sandpoint who didn't seem to want me to leave. Probably shoulda stayed. OVER.
 
Sure, it might seem like a lengthy drive, but you would see some wonderful countryside. :)
That is the truth! Even the 90 minute drive from Spokane to Sandpoint is amazing. Oh well, if Duke wants to go next year, we do it every third week of May ;)

Bob, you are kidding me! You have a relative after whom Bonner County was named? You must tell me the story one day when you get time...maybe do it in a PM so we don't get yelled at, but I'd love to hear it.
 
Dude, I don't hate at all! I have nothing but love in my heart for you and what you've EARNED in your life (accent on EARNED)! I'm just busting chops a little...everyone gets their turn in the barrel with me. I'm sorry if I bummed you out.

No worries, mate! I was just bustin' a little chop back atcha. :D

Your comment was actually pretty funny, and I knew (or at least strongly suspected) that you meant it all in good fun. :cool:
 
Jim took a different approach and used a big honking PA type horn tweeter that seemed to be crossed over very low to 'plug that upper mid hole'.

Okay now you REALLY got me interested. You see, that's similar to what I'm doing in another cab.

Can you tell me the dimensions of the mouth of the horn, or even just an estimate? That would pretty much tell me how low Jim's horn can go with good pattern control.

Thanks!

I have an HT212, and once I find it (:eek: ;) :D) I can take that measurement for you. :cool:

My HT's are all gone, but I believe they all use the same horn (except for the 112's). It's the same one that is in the IP310 picture on Jim's website. It seems to be or at least similar to the B&C ME60, which is around 10" by 7" and is listed to work well down to 800hz.
 
There's a pretty good picture of it on the Berg Website.... go to products, then IP series, then IP310. I was just guessing on the horn. It's about the same size as the cone of a 10" speaker.

Eye-test? ;)

It's about 7" across at best!

Now this is a big horn tweeter:

That's a 15" woofer below it, they cross over at 500Hz!

I'm a big fan of the Peavey 44XT Had a bunch of these in my PA.

$380 bucks is not a play thing.

I'm sure other manufacturers make similar units, JBL etc. The trick is to let the main bass speaker do its job and fill this in above that. Crossing this over at 500 is flat insane. The recommended 1000Hz with Bass would be much better. Hook this up to a huge horn and you have what Johnny April is doing.

This is where I will be going once again. BOB
