good mix. leaned one hour to 30v/35volt output limiters

Good to have infinite volume knob

Heavy Metal dipole speakers like the Kylon Gaia, with the help of extensive DSP and watts-watts-watts, have been getting good reviews. Kylon mounts all speakers by their motor to a massive metal skeleton to minimize baffle vibration. Kylon woofers have dipole optimized T/S parameters(Lambda TD12D, TD15D).

I believe that there is Order even in a Chaotic Universe. The selected drivers are very well suited for a high efficiency 3-way sealed box speaker. The entropy of the audio universe will gradually move them in that direction.

Things have changed in court of appeal.
now i have
high: tpl200h
mid: ?
lower mid: ?
low: 18n862

thinking phl 1130 to mid 500-2000 but could need heavier low mid, maybe 12" or even 15" to get that hit. 80/200-500 is bandwith maybe.

exploid my hifi 6/2 and got first impression 420-2500hz nude.

are you ready?

Sealed Boxes. A smooth controlled directivity curve across the TPL-200H "desirable" 2KHz crossover needs a midbass speaker which has ~80 degee(+/- 40) directivity @2Khz. The attached polar measurements of the old 10" JBL 2123H shows that this is possible with a few 10" speakers. Curvelinear cone? Triple roll surround?

The year 2015 $170 Beyma 10MI100 version2 has the efficiency and Xmax required, but I have not seen a polar measurement. Does anyone have polar plots of a 10" midbass with (+/- 40) directivity at 2000Hz?

For a dipole, you may get the best sound by removing both TPL-200H horn and rear chamber and allow it to work as a wide dispersion dipole tweeter. To match the wide dispersion of the TPL-200 dipole at a 2000Hz crossover, you may need to consider a 6" - 7" midrange with a small size NdFeB motor providing free dipole air flow, plus adding a 10" midbass between your 18" woofer. Naturally, this dipole will be a much lower efficiency speaker design than a sealed box design. B&C NdFeB speakers like the 6NDL38 with Qts=0.42 have positive comments.

0011 15W750 - Low Frequency 15W750 : Eighteen Sound - professional loudspeakers
0010 15ND930 - 15ND930 : Eighteen Sound - professional loudspeakers

Could be the nd930. heard that deltalite is good.
Nd930 is used in finnish diy nitrosäiliö, low inductance. W750 is more heavyweight.
All of these have some little peaks on impedance graphs.

Polar response is new thing for me, i think i'll take the horn off and go some 6.5". eighteen sound has good 6,5"'s, phl aint much open on back
