Try this for a Jamborette. I hope I made it well for the bifurcated profile: lenght of one path and areas of two paths summed.

I modelled Jambo in Hornresp. I left the data file of it at my office PC, so wait until (European) Monday morning. And a few hours more for Jamborette as I need to recalculate its size.

I have a set of spikes to mount under.

KG 3.5. I wanted them to have a present-day look and this is the outcome.

Try to model this one: Precision Devices PD.153ER THIELE SMALL PARAMETERS Fs 40 Hz Re 5.87 Ω Qms 8.65 Qes 0.22 Qts 0.21 Le 0.48 mh L2 3.09 mh R2 7.17 Ω Vas 218.76 litres Mms 74.36 g Sd 855.3 cm2 Cms 179.67 µm/N BL 22.44 T/m Xmax 5.7 mm Vd 0.473 litres Pe 400W

Have you ever considered other than miniDSP kit active crossovers? For example there is a kit available: Najda DSP by WAF with features which are not available in many OTC units. These extra features are: 1. 48, 96, 192 khz sampling rates. 2. I2S input (with help of addtional USB-I2S converter one can connect PC and and stream all what one wants, files, Spotify, Tidal etc.) 3. Integrated volume control of analog outputs, IR operated (no need for pre-amplifier, one can use Najda like an ordinary integrated amplifier with volume knob) 4. Several preset crossover setups assigned to IR remote controller (gentle slopes for low volumes, extreme slopes for loud listening for example), changed instantaneously. 5. Swapable opamps. Besides it has all kind of filters, delays, EQs, FIR. It accepts analog and diigital (SPDIF and optical) inputs, has 8 outputs, easy expandable to 10. Priced EUR300 ($330) without power supply. I am going to set it up soon and will share using experience. --- edited: 6. Digital outputs (10 channels by SPIDF) so one can use Najda as pure crossover and further process divided signals in external DACs.

I think that better imaging of LSII comes from the new crossover network. I also have LSII and I noticed that changing crossover for simpler one (lower order filters) deteriorated imaging.

La scala II back chamber comes insulated with foam out of factory.

Moray's k-tubes intrigued me and I have tried a very very simple set with my spare HF200. Too soon for conclusions, but sound has seemed to have both (good) features of horns (quick, detail) and direct radiators (hi-fi softness as opposite to PA power). . .

I have both HF200 and HF204 (HF140 and HF144 with 2" adaptor). They sound differently, for 2-way 204/144 is better, HF200/140 lacks some brightness.

Bacek, try to model Monacor SP-38/300PA. Impedance (Z) 8 Ω Resonant frequency (fs) 48 Hz Music power 600 WMAX Power rating (P) 300 WRMS SPL (1 W/m) 99 dB Suspension compl. (Cms) 0.21 mm/N Moving mass (Mms) 78 g Mech. Q factor (Qms) 5.68 Electr. Q factor (Qes) 0.24 Total Q factor (Qts) 0.23 Equivalent volume (Vas) 213 l DC resistance (Re) 5.9 Ω Force factor (BxL) 22.0 Tm Voice coil induct. (Le) 1.2 mH Linear excursion (XMAX) ±4 mm Eff. cone area (Sd) 855 cm2 So we get Vb=60l and Fhm=417 Hz. Not bad. Black: Monacor Gray/Red: Peavey

I will check, thank you.
