    The sleeve does make a big difference in the inductance and the distortion. It is a very high-end motor design. The response has more peaking than the provided graphs indicated, I'm afraid. It was easily handled in the crossover though.

      Jeff, shhh. You are going to further strain my bank account. These drivers are already on my short list to work with :D

        I didn't use the links at the bottom of the page. I entered the incorrect woofer description into PE's search. When I saw a discrepancy in the dollar value in a couple of earlier posts I noticed the math didn't add up. My intention was to state the correct value of the drivers. Unfortunately, I wasn't aware that PE had an omission on their driver description.

        Please, don't take this personally. I'm not trying to belittle the kit.

            I did a quicky ML-TL for your design using Morel's small-signal T/S values. Based on PE's listed external cabinet dimensions and descriptions of the Soltice, the cabinet I modeled had internal dimensions of 7.25"W x 8.75"D x 36.5"H. The modeled sensitivity for a paralleled pair of the woofers was a smidgen under 95 dB SPL for 2.83v/1m (without any resistance added in series). which implies a woofer sensitivity of 89 dB for 2.83v/1m, 2 dB higher than specified. Substituting the large-signal T/S values Morel lists dropped the sensitivity by about 1 dB for the paralleled pair. In any event, you stating a sensitivity of 87 dB for 2.83v/1m sounds much more realistic.

              How about that thermal capacity with 2 3" voice coils with Titanium formers!

              Surprised that PE didn't have something like this done with their Esoteric 7"
              which should perform well based on this:

              I get that this is an all Morel design.

                Jeff, thank you very much and also to Erich for this. I really wanted to do another build for my spare room in my new home, since my Statement Monitors are residing in the living room. My physical abilities to build from scratch now are gone, and I was thinking a kit with flat-pack cabinets like this would be something I might be able to accomplish with a little help. I wanted a higher-end design, something w/o stands and here this design is! I've sold my home out in the sticks, so I wanted to treat myself for all that I have endured the past few years, as a reward. My new place does not have the nice 800 ft2 shop that I used to enjoy, and no room here for my table saw, router stuff, radial-head drill press and my lovely homemade work table. This is a perfect option for me. Guess I'd better get on it! Thanks again for Erich and your efforts.

                  Re: New Kit via PE.... "Solstice", Nice looking one too, Jeff!

                  Jeff, would the Solstice be comparable to say....a Continuum, Karios or Triton with a small sub? (I know this is a BIG BROAD question)!

                  I guess I am trying to see if I build the Continuum with a sub or would I be getting as good of bass with this great new design.

                  Thanks,

                  Robert

                    It really depends on what someone is after. True subwoofers usually have more output capability in the deep bass than you may get from a pair of 6" woofers. However, if you don't need high SPL's and if getting into the mid- upper 20's in your room with music at moderated levels is all someone needs then the Solstice should make them very happy. It certainly has more extension than my Kairos or Tritons have, and the footprint is about the same as small speaker on stand. With midbass and vocal reproduction that is every bit as good as the Kairos but with deeper bass, this was a very nice speaker.

                      Thanks, Jeff!

                      Edit: The flyer is out and the specs are out! And, for my little knowledge of graphs, these speakers look wonderful.

                      TWO PAGES....NICE WRITE UP JEFF!!!

                      And, I do have the WAF acceptance...even though she has not seen the size! (:

                          Thank you, Robert. I had not seen the final spread until now. Looks pretty nice. Here's a response curve that they didn't show. It's a measured frequency response on the tweeter axis calibrated to 2.83V at 1 Meter with the summed Nearfield bass response spliced at 150 Hz for what would be a full-range Quasi-anechoic frequency response. I used 1/48th oct smoothing and an 8 mSec gate.

                              When you said "half space response" you mean against a wall?

                              I desperately need these....

                                No, not against a wall. Half space just refers to the way we rate sensitivity on a baffle. However, in this case the speaker has the correct amount of baffle step compensation for free-standing placement 3 -4 feet out from the wall.
