Beautiful work, Yep! Congrats on your new speakers. I love the floor mounted angled up look with feet! Zebra wood is very cool too. I am glad the vented alignment worked out. We will keep your dimensions in mind for anyone else wishing to make a more compact box with deeper bass.
Jimk04, yours are sensational as well. A more conservative studio monitor look.
It’s nice to see all the creative angles people are coming up with for this speaker.
Happy New Year everyone!

Jim, YEP, great builds, congrats!
Back to the RS: I checked both boxes, there is no sealing, and also no rubber gasket under the bezel.

Thank you, X.
Regarding the stuffing of the FR-cone, is there an exact requirement for the amount/weight - I have found nothing for this. I use 11 gramms now with about 1in free space behind the FR, but I don't know if its okay.
I will now finish the speakers (it means min. 2 weeks without listening to them 😱 ), so now I could make the final adjustments.

Hi X, everyone. After some days of listening and tweeking the XO (both in Xsim and in real life) I decided to remove the FR l-pad attenuator. Probably a ~1db attenuation is still required, but I don't have the right resistor values so, for the moment, I will leave with a little bit of extra mids/highs.
Has anyone who is using rs100-8 (+rs225-8) reduced/eliminated the attenuation on the FR?
Unfortunately I cannot perform measurements, and I have to trust my ears...
Any suggestion will be appreciated
Thanks guys!

The RS100-8 is 84.6dB at 2.83v. The 10F/8424 is 86.7dB. The speaker is 82.4dB sensitive. Current XO is using 5ohms over 5ohms. I think 2ohms over 8ohms is about the right level but really it is your own preference. Whatever sounds right to your ears is the right level. Some people prefer the HF to be tilted down about -5dB relative to the bass at say 50Hz.
That is easy to adjust. 4 screws to remove driver. But it’s not critical. Not enough and you get reflections. Too much and it sounds dead.
Ok thanks. I've tried a similar attenuation with 2.7Ohm/15Ohm but still I've found a lack of "air". Anyway, as you said I like them better without attenuation, and they sound more like my studio headphones
I forgot that you also have yours sitting on the floor, and even tilted up, the sound is probably 30 deg off axis so you will need the extra treble. It makes sense and so go straight through then. If you had them up on a stand with the woofer at ear level, you may need to go with some attenuation. And sitting on the floor with rear wall reinforcement, you probably have enhanced bass by 6dB and it may even make sense to use something like a Faital Pro 3FE22-8 (91dB) here with some attenuation for higher sensitivity to give you the treble balance you need.
Note that there might be a floorbounce dip around 150Hz or so that would not be there as much with a higher stand-mounted speaker.

Understood, this make sense (of course 🙂). As a matter of fact, in my xsim simulation I used the 15° and 30° response for the RS100, and this led me to remove the l-pad. I will give a try to the 3FE22 in the next weeks. Thank you again for all the precious comments/suggestions
This low dip requires rather long path length difference and are typically from ceiling if both speaker and listener is closer to floor (than ceiling). It is possible to get a dip this low from floor, if path length difference between floor bounce and direct sound is roughly 110cm, or almost 4 feet, 1/2wl at 150Hz. If listening distance is 2 meters, speaker is ~90cm from floor and listener stands up, head closer to ceiling than floor, then it would be floor bounce 😉 If listening distance is more than 2m, or ceiling lower than 2.5m the dips move up in frequency. More importantly, the high bass and low mids are full of these dips from various boundaries in the room, and the dips move quite a lot with the listener.
See attachments, made handy dandy calculator to inspect and illustrate stuff like this! 😀

Yes, if woofer is only 0.5m above floor then floorbounce dip is probably closer 600Hz range. That’s right on vocals range but dips in general are less audible than peaks.
Hi,
I now started to finish my speakers... and so I had to replace them with my Sonus faber Venere 2.5. Oh boy, they are compared to the FAST TL boring, undetailed, limited in frequency range, dead. Bad. Wow.

Hi X, regarding reflections, is it possible to cover the 1in part of the cone with acoustic felt (with a 1in strip), where no stuffing will be made (the free space behind the RF), in order to eliminate possible reflections? Or is it unnecessary or even a bad idea?
