Exactly. I was thinking something like poor man's Mbrennwa's OSMC but oldschool design, no waveguide, felt on the front baffle to control the diffraction of the tweeter. X-over frequencies probably in the ballpark of 400-500/2000-2400Hz
Bass is known by now, midrange is used in Kii Three and the tweeter can not be better even for much more money. Copper cap, aluminium front plate, probably t-yoke, silver lead wires... Only thing that could be upgraded is rear chamber - if it is anything like the one from RDC series, it will be slightly resonant. I'd probably glue 2-3mm thick aluminium plate on the back with some contact cement and be done with it.

Don't commercial companies get some discount when buying hundreds or thousands of drivers?
@Zvu
The FSL midrange very good regardless of price.

I would suspect that one could ask Tymphany to put a copper sleeve in that thing if you had an order of 500 units...
Btw the SBS160F35AL01-04 well behaved as far as 6" woofer goes:

Great drivers available to people near THLP…

Back in the '90s when a friend of mine was in the business, the cost ratio for 1000 pieces was from 10 to less than 3. I remember he also bought 4 Seas P17 for a friend of mine and the discount was about 50%. Differences of cost are huge.
Or one could just use more pieces of it 🙂
I'll finally have few free days around xmas holidays to catch up with you guys 🙂
@ScottG I knew you'll like the driver choice - especially the tweeter 😉

Many years ago I used to work in electronics distribution.
Even though DIY speakers may be “spare parts”for sure, buying single unit quantities is like buying retail.
Costs of packaging, pre and after sales support, returns need consideration.
A fuse that costs a dollar usually costs cents in thousand unit quantities.
While i might try two midranges in some configuration, it will probably not be this one. I've bought 4 of these and will probably use only two. Other two will remain in reserve. I don't want to find myself in situation where i really like the sound of speakers, something happens with one of the midranges and i have to dig for another pair of transducers that fit and completely redo the crossover. Price is right so i decided to buy 4 of them. I listened them multiple times and i really liked the midrange.
On the price matter - it seems that TLHP is one of the last sane dealers of transducers in Europe. Those price are with VAT.

SBA 3-way floostander on a budget (less than 300€) I have in mind: 30*80cm baffle, closed box 60L, x-over frequency 300/4000Hz
SB26SFCL38-8
SB12MNRX2_25-4 or Peerless TC9 / maybe in a D'appolito config...
SB26STAC-C000-4
Preliminary simulation

This driver is sadly NLA (was priced the same as FSL-0152) but is another example of a high quality/price ratio:

Front baffles CNC-ed and hopefully a 2024 project. With SB-21 tweeter in Augerpro's 3D-printed WG.

You can improve the directivity in the HF area with using the SB19…..a remarkable but overlooked tweeter……with a 3.5” mid crossed at 4.5k as in your sim, the little 19mm is more than up to the task and the off axis response is crazy good!
I like the damped OB approach! Working on a passive Cardioid with the Faital 15pr400 for a few months now. Was hoping to get there fully passive, but I’ve come to the conclusion that I’ll need 2-3 bands of parametric EQ to even out the power response. Waiting for the Dayton 500w DSP sub plate amps to be back in stock before proceeding but I’m really encouraged where this is headed…….I’m anticipating a flat response with an f3 of 35hz close to the wall behind which is the beauty of cardioid….no reason to drag them out into the middle of the room……2ft cabinet depth is planned.
If I can do a passive cardiodid mid from 800hz up to 4.5khz I’ll be in heaven……but if not, a 50x50 1.4” CD on a horn would be ok too. $1k budget is blown on this though……I’m over with just drivers and 2 lenses.
I am in the middle of designing a timbre-matched set of L/R, L/C/R, SR, and Atmos Speakers using the Sica 5.5 and Sica 6.5 coaxials and 12" as well as single and dual 8" woofers.
Design no1: 5.5" or 6.5" Coaxial and 12" LaVoce SSF122.50L in a 32L sealed enclosure, for L/R (alternative woofers B&C 12BG76 for a higher end speaker or a Dayton Audio DS315A-88 for a slightly more affordable option).
Design no2: 5.5" or 6.5" Coaxial and dual 8" B&C 8BG51 in 37L vented enclosure or dual Dayton Audio RSS210HO-8 in sealed enclosure for L/C/R
Design no3: 5.5" or 6/5" Coaxial and single 8" B&C in vented enclosure or single Dayton in sealed enclosure for Surrounds.
Design no4: 6.5" Coaxial in 6L sealed or 18"L Ported enclosure for Atmos.
Design no5: 6.5" Coaxial + 6.5" Sica 6.5H2.5CP woofer 2.5 way, in 21L sealed enclosure for Atmos
All speakers will be designed for either wall mounting or very close to the wall.
For the Coaxial I plan to start with the crossover that Sica designed for it and modify it as needed for the respective enclosures, and go active for the Woofer-Mid crossover for a Hybrid Active/Passive 3way design.
Crossover will be at 2.5K for the 6.5" coax and crossover to the woofer will be between 160-380Hz
For the surrounds and Atmos, I may go passive all the way.
For the moment I only have the 6.5" Coaxial in my hands and I expect to start working on it at the beginning of 2024.
If I like the way it sounds it will be the driver of choice in all speakers. If not, it will be used as an Atmos speaker and I will get the 5.5" version which should be very close in performance but with less low-end and most likely better behavior at the crossover frequency.
The 5.5" has been used so far in quite a few designs with very good reviews so I expect it to sound very good despite its relatively low cost (95€ at a CZ website)
Overall cost is well under 1000/speaker but it can go close to that if you go fully active with Hypex modules and the B&C 12" woofer.
The Sigberg Audio and the Antelope Audio speakers built with those coaxial drivers cost 5300€, (SBS.1) 12,054€ (Manta) and 4.600€ (Atlas 8i) a pair respectively.
