But Mk2 is, from what i read, an improvement made to handle some of the complaints regarding the tweeter.
The main difference vs mk1 and mk2 is the crossover between the upper second woofer, LR4 filter slopes for the mk1 and LR2 filter slopes for the mk2. Point of crossover is lower for the mk2, 2 khz and 3.3 khz. The two versions may sound a little different, but IMHO differences are subtile. The mk1 beeing an open design, I think it may be cheaper to build the crossover.

Concerning the tweeter, some people have complain about the D2608/810921 sounding harsh, in most of the case it can be fixed by levelling the tweeter level and/or adding an RLC notch filter around 10 Khz.

Thanks for the info .


Anyone have any idea about how Jeff Bīs Solstice handels compared to the Nomex? Because very weak exchange rate and weird pricing over all they have about the same price here.

Hi Smoothy,

If you like your ZR71 speakers, why not adding the bass section of the Jensen Seas to your speakers crossed with an active crossover ?

Jenzen CA

See also Intro section Ellam 2 way -> 3 way conversion

Ellam-FLEX-3W

In a second time, you could build the top section and change the tweeter or adapt the crossover for the 27TDFC.

The Solstice is a 2-way TMM design with the crossover at 1,700Hz, which is a 8" wavelength with a 11" center-to-center between the tweeter and bottom midrange. Xdir simulations show a lobing pattern which creates concerns. The modest efficiency of the midrange favors wiring both in parallel as a 2-way TMM or MTM.

Any independent polar measurements available for the Solstice?

Why wouldn't you include both mids in the simulation?

I have built one of CJD's designs, and I would recommend his speaker designs.
