The tuning of the original Debut was kinda bottom heavy. The B5 has a 5.25" woofer and a 27 Ohm sand caste resistor in the tweeter circuit. The B6 has a 6" woofer and a 22 Ohm sand caste resistor in the tweeter circuit. To bring the level from 2.5 Khz (tweeter) 2 dB up and improve "resolution" I used a thin film 22 Ohm film resistor. Then used 5" felt around the tweeter to prevent baffle diffraction and enforcement (tweeter now more point source, without the whole baffle area) As I use them with speaker grills I also treated the edges of the grill with felt to prevent diffraction. Result is a very precise soundstage and imaging, together with more clear highs. You have to know 22 Ohm and 27 Ohm are industry standards. A 25-ish Ohm would be perfect if you don't use the speaker grill. But hard to get. However I must use the grill else our cat destroys the drivers :) . Edit: for a B6 use a 20 Ohm thin film instead of de existing 22 Ohm.

@@tweakradje So the resistor swap would make the speaker brighter correct?

@@sebsefyu yes it does

I experience much better soundstage. But it only works with replacing the 27 ohm resistor for a 22 ohm thin film (easy and cheap), removing the tweeter cap and using the speaker grills. I also put felt strips on the speaker grill inside vertical and horizontal edges. No diffraction. Thinks this is the best ELAC Andrew Jones speaker he designed for the money. Simply amazing.

I'm am surprised he choose to use pretty good xover components :) After this model it went downhill. Apart from the resistor (27->22 Ohm) I removed the clip connectors on the binding post side. The new resistor causes a +2dB on the tweeter. The felt around the tweeter and the use of the speaker grill with the lower resistor results in a +1/2dB from the naked original speaker after 2.5kHz (tweeter). I must use the grill to protect my drivers from the cats. Without the grill a 24 or 25 Ohm thin film resistor would be perfect, but they are not industry standard. The polyfill is personal taste I guess but I think the box needs it for the bass. I first used it on bottom and the whole back (with a hole for the reflex port) but that was too much. Now it is only on the bottom and on the back up to the reflex port.

No

t-line. Look for Cyburg Needles

For both questions I suggest to use the original drivers for the design: Dayton Rs100-4 or 8. These are alu cones with more high and a much better power handling that gives you better bass and low mids. The Tang Band w3-881sjf is a little too small for this enclosure if you ask me.

I do now but in Cyburg Needles.

If you like heavy bass this speaker with 3" driver is no good. Only if you use 4" full range you get nice bass. Then no need for subwoofer. Use driver like ADW Rs100-4 Dayton or Tangband W4-1320SIF with X-max of 3-4 mm.
