Cranberry Lambics

Re: Cranberry Lambics (build in progress)

Is that the optimal arrangement for the inductors??

I thought one should be set like its rolling the other.

(And it would be bad to look thru the hole and see the other)

Re: Cranberry Lambics (build in progress)

I'm assuming you're looking at the highpass. I've not noticed anything particularly disturbing in the tweeter with that config. I knew I needed them to have a 90 degree offset which is why the LCR inductor is standing.

One thing to note, after talking with Wolf, I found out that the order of the LCR doesn't matter since it's in series. I'd argued with myself that it shouldn't matter but figured I'd reposition the parts anyways in case there was a problem with my logic. :rolleyes: So getting back to the point, the standing inductor could be placed further away from the inductor laying flat if someone else was building a set lambics for themselves.

On the low pass I'd posted that config up for feedback and was advised to rotate the iron core inductor to it's current positioning so I think it's ok as is.

And since it was asked somewhere else the aligator clips were there only for testing :D

yeah that's the one that stood out. Just pointing it out becauase I just assembled an XO (for the Lineup R44), and found references on this board that the "rollover" alignment was best. Its just an easy rule of thumb , but I did not test (and don't remember enough college physics/electronics to confirm).

Re: Cranberry Lambics

Would you mind providing the internal dimensions of your cabinets, or point me to them if you have already done so?
Thanks,

The cabs were made from 5 (40" x 8") cuts of 3/4" MDF. So the internal dimensions ended up (6.5w" x 8d" x 38.5t"). External dimensions are 8w" X 10.25D" x 40" Due to the removable baffle portion I'm gaining slightly more area from the cutouts.

I've also been simming using the SB25 tweeter's in PCD as a possible change if I build another version of these for myself to lower cost and get to fewer crossover parts. The originals have been dropped off and now reside with my brother in VT.

I've had a few PM's about the lambics so I've added pictures for simmed revisions for SB25 or DX25 tweeter if/when I build another set of Lambics. These crossovers are only simulated at this point. If someone else tries them let me know what you find.

Re: Cranberry Lambics

Hey, how do you like the sound w/the DX25? That tweeter was on sale at a great price DOTD - I'm sure lots of folks picked them up, and are those the $10 6 1/2" Peerless woofers?

I liked them a lot and was comparing them head to head with the SB29RDCN tweeter which was/is in the speaker project for myself. In general I liked the top end on my brother's speakers better and the low end of the FW168's better than the Peerless. Cost wise though the Lambics were ~$250.00 and the Ruinations were ~$400.00 and I didn't really hear enough of a difference to justify the extra money spent on my speakers. (Note I really enjoyed listening to both speakers I just think the Lambics give you more for your money)

I think between the two tweeters the DX25 was more detailed and accurate on the top end. I think this could be noticed mainly when listening to older recordings where IMHO the SB29 masked some of the imperfections in recordings where as the DX25 played what it was given.

As for the woofers yes they are the $10.00 peerless buyouts so for a little bit you could build this project for $72.00 spent on drivers. I went ahead and bought four more of the tweeters when they were on sale and already have 4 of the peerless woofers on hand so I might build another set of lambics next spring. With the original pricing on the peerless woofer being $43.00 each I couldn't enter them as a less than $200.00 speaker at next years Dayton gathering, so that took a little wind out of my sails for building the next pair.
