RSS315HF-4 as the anchor of a 3-way???

Pete, where in Kentucky are you going to bring them and on what date(s)?

If I bring them to Kentucky in November, I'll play an older jazz recording, that I think is Lena Horn, singing "Good Morning Heartache" that is a crystalline recording with the most subtle intonations meticulously captured. I swear I can see the her forming the words with passion when I close my eyes.

I guess you can tell I really like them . . . :o

I love they way they look and if they sound half as good, they're keepers.

The Verve 50th Anniv. box set version of this is a good test track too, for vocal realism, cleanliness. Ella sounds like Raquel Welch looked.

I compared one of my speakers to one of the high end Revels, and the Revel nailed Ella better, less "breathing".

Pete,
I see a lot of designs (mine included) voice the 2 to 5 kHz region lower down in level.

One question: how do you find vocal intelligibility? I find acoustic instruments sound more natural with this approach, but that vocal intelligibility suffers.

It wasn't an "on purpose" kind of thing, just sort of arrived at it via long term listening sessions. There really isn't a trough in that region in my design, as it's flat from below 800Hz to the diffraction bumps of the tweeter response starting at 5KHz. That accentuated region above 5KHz goes away off axis. And you'll also notice that the difference in level from 800Hz to 5KHz is just over 1dB. You could say that from 500Hz to over 10KHz, the response varies by +-.75dB . . . that's pretty darn flat.

Others mentioned from the Iowa event that the midrange performance was the surprising, and pleasing aspect. Everyone expected a mighty low end, and they don't fail to deliver there, but it was the mid clarity that really stood out. Of course, a lot of that goes to the Scan 15W, but another huge non-contributor to the sound has to go to the cabinet construction of D,Rose. Those cabinets are dead, dead, dead, and stiff stiff, stiff, and massive. They image really well for something so large, and project a very believable sound stage with a good recording. Close your eyes and they just don't sound like a BIG speaker, but they do have big sound. Vocal clarity is something they truly excel at.

I just finished reading through this thread (referenced in from another thread on the RS drivers, thanks Pete). Very thorough and impressive writeup and documentation of the speaker build. Also, having another pair(s) of experienced ears certainly added to the evolution of the build.

I like that the build has a completely passive crossover to keep things "simpler."

Is there a finished crossover schematic that incorporates all the changes; padding down the mid/tweet levels, raising the the woof to mid crossover frequency, to the notches in the the SS 15W and the RSS315Hf?

Sorry I missed this post raiderone. I hadn't drawn a schematic, just posted the PCD pages showing the values, from which a schematic can be created.

But, I went ahead and drew up a more traditional representation. Below that is a shot of the PCD simulation using the on-box responses and the values in the schematic. The plot becomes inaccurate below 300Hz due to room interactions, but believe me when I say that the low end blends seamlessly with the mids.

For some reason I was thinking that these were sealed on the low end??

Not sure why though.

Did I miss something? Did you use a PR with these?

Yes, its mounted on the back.

They are indeed linebackers, weighing in at just over 130 pounds each, and attractive as well.

Hey, even I have to admit that Howie Long is a fine looking man!!! :o

I built these to be true reference quality speakers, with a full range (to my ears) from the lowest bass to 15KHz (my upper limit). The RSS315 most assuredly meets the criteria. The low end is deep, full, and very detailed. The PR extends the in-room response to below 20Hz, and really helps keep the woofer under control on the bottom octave.

If anyone is contemplating using the RSS series subs for woofers, GO FOR IT!!! You will NOT be disappointed in their performance. I thought maybe they might not be up to the challenge of blending with a Revelator, but the Daytons did not disappoint.

Bad camera not withstanding, those are just beautiful!

Re: RSS315HF-4 as the anchor of a 3-way???

Wow, very CHUNKY! :D

I bet those got some nice bottom end to them...

Whoah, your attraction to linebackers would be a subject for another forum...:eek:

Reminds me of a linebacker I knew once. VERY ATTRACTIVE!

Well, even though the camera is a cheap piece of junk, the light was pretty good and I got a decent shot of the finished walnut.
