I have PCD 2007 (great stuff!) and don't see any jpeg artifacts in the diagrams. Maybe a little fuzziness from a resize on the text. Nothing bad at all. What did I miss?

Only the earlier versions run on my Mac, the images you see Michael, might well be the original gifs i saved out for Jeff.

Good design I just tested the design for Bob in the parts express cabinets, for those who would go that direction.

No change needed to the crossover that Jeff designed it works..

Indeed Dave, for WB. They called it their tactic driver/cone/technology iirc. Woven poly, that is then heated in a specific way and then cooled so that part of the poly becomes far stiffer whilst retaining the materials self damping characteristics. At least that's the way I remembering it being spun in a review I read way back.

It was what i used for the drawings i did for your 1st passive XO design SS software (late 2001 & early 2002) and for the earlier this article on TLS.org. I guess you have been using them over and over again, and each time saved as a jpg more noise added.

I misspoke when i said it was my EL166 XO revised (i did representitive drawings for that), i can now see the origins going back mush further than that -- sorry about that.

If you have been jpging all your drawings as much as this one, you should be embarrased by their quality, it is not commensurate with the quality of your XO & speaker design prowess. Just look at all the noise around the text. A drawing like this should always be saved as a gif or png. You have not been kind to the originals.

Yes, you are right. I was going to tell you that I built my "crossover schematic builder" out of the gifs that you made for me about in, I think, 2002. It simply pieces the little parts together to make the schematics I draw. It is pretty crude, but I thought it was OK for what I was using it for. I know there are real programs for doing this out there now, but I just kept playing around with my own little spreadsheet, since I had it working for me. Normally, I save them as gifs, but for some people they like me to send them jpgs. I'm not using them over and over again like copies of copies though, it doesn't work like that. As for being embarassed, I would only be embarassed if the speakers didn't sound good . The drawing itself isn't really what I am all about.

Did you ever do anything with those D21's I sent you years ago?

Jeff

Sort of. I passed them on to a friend who built a nice set of stand mounts

Any whining about bass performance misses the point I'd reckon.

2x 5" CSS VWR126X polycone bassmid and the CSS fabric LD25X tweeter. Whole drive unit and crossover kit available at CSS: Creative Sound Solutions - Loudspeakers, Parts and DIY Speaker Kits

Naturally the review is incomplete for me without a schematic and frequency response, so I'll save you some legwork. Beats me why there is a 0.47uF/0.25mH tank at 14kHz on the bass filter...but I'd trust Jeff Bagby's reasons...
For common folk, uneducated in the D'Appolito Theory....A Geometric Approach to Eliminating Lobing Error in Multiway Loudspeakers, (had to look that up), I can proudly say that I am glady addicted to this midsize monitor suitable for large rooms. Why, because it is in a 20' X 24' 9' room and performs as a large tower!

At normal listening level, I can hear it clearly and loudly from room to room. I guess I have to say this again, the bass is astounding, I really have to say that Jeff, I think something magic is happening here. I wish someone could explain it to me.

As I mentioned before I have a DIY Servo sub and I know what it sounds like and I sware I am hearing it. Doesn't make any sense I know. I constantly get up and see if the center and height speakers are on as the wide range CSS woofers just keep on dumbfounding me while listening to 2 channel, not to mention the excellent detail.

Thanks, RAW, I need to re-sand the cabinets one more time.

If any of you are familiar with the Philharmonic Speakers by Dennis Murphy. These are my 2 channel/theater along with the Philhacenter that Dennis was producing, but with the shrinking space with the additional new furniture, they would not work there any more, thus a smaller narrower tower and that is why I chose the Tritons to replace them. With all the information and reviews, I knew I couldn't go wrong even in a large room.

RockLeeEV, I highly recommend the LD25X tweeter. Never heard the other one, but this is a "gem" indeed as Jeff mentioned. It certainly has stopped me looking further.

Thanks!

Curious, does anyone find the LD25X sounding bright?

Thanks!

Yes the LDX25 has the rising response.
I believe ya have another set of crossovers coming your way....I could be wrong but thoughts so.

The rising response of the tweeter, place a 1.3uf cap across the tweeter terminal.Simple just remove the tweeters and solder the 1.3uf cap to the positive and negative wire for the tweeter.Then reconnect the wires to the tweeter.
Then LMK what ya think.
