have some questions:
1. any comments on 2459a vs 403a? i have both but have the OB for the 2459s only. the 403a is in a bookshelf baffle. i find the highs rolled off on the 403a and we experimented using a tweeter to bring out those highs. will they may sound more extended in OBs?
2. the local plywood we used are light in weight and i can feel the entire OB vibrate with the music. perhaps that helps in the sound as well . would a heavier more solid wood be better. what improvements in sound can i expect?
3. there is a slight bump in the mid-bass which i suspect comes from the 2459a interaction with the floor. will run a frequency sweep to find out what frequesncy that is. it's not distracting but noticeable.
4. where can we get specs for these "budget" drivers?
5. will other drivers work as well? am thinking of the fostex. these are readily available. am having 3 sets of OBs made this week to play around with...

Thanks again for the opportunity to hear those altecs on open baffles. When I got home sunday, I hooked the altecs 403As, no baffles, just on the floor to check its tonality. And I heard exactly what my memory tells me of your altecs on OBs.
I wish to thank Joel too for inviting us for a listen to his system. His cnsist of an altec pair of woofers, and horns that take care of the mids and highs. To my pleasant surprise, this is my first time to hear both woofers and horns tapered so well (ingenuiously controlled) to sound like a typically good midrange, and separate tweeter. But with typical mids and tweets, you don't get as much a broad soundfield as these horns. I suspect Joel has some well-kept secret recipe employed in the xover that made these altecs work very well in a home environment. Care to share that secret Joel? Grant and I met and listened with Rex, who is also an LS 3/5a user. It seems to me LS users are at this point also entertaining the propspects of going SET with Altecs. And why not? I like what I heard! Clear and natural as the recordings would allow! It is I think that midband presence that make these altecs hard to ignore once you've tried them. That was indeed some horny night over good food and red wine, with a vintage Garrard grooving those LPs! Surprisingly no "pops and ticks" there. A very forgiving setup from Joel on what could have been otherwise a bullish horn!

Thanks for emailing me directly! I wouldn't have noticed the thread because I was practicing....anyway it looks like OB building season from around the world. During the holidays I received emails from quite a few OB builders here in the USA, S. America and Europe.
