Same size as the 10F/8224, it should fit.

I don’t pay a who;e lot of attention to people’s measurements, as you don’t really know the context.

I find the Alpair 10p quite nice sounding (caveat: most of my listening with the A10PeN)

Grafs are copied right now from www.hifisound.de
How 10F/8424G00 characterised as midrange in contrast to
10F/8414G10 characterised as fullrange. As anyone can see Resonance fs fs: 90 Hz for 10F/8424G00
Resonance fs fs: 100 Hz for 10F/8414G10
furthermore above 10KHz the graf on axis for the former looks to me better

I haven’t heard the 8414 yet, but the 8424 we have are decidedly soft on top. The 8414 has a higher Qt which gives it more bass. Sims attached. Sealed + a close to flat reflex (the 8414 box can be 2x the 8424. The 8414 has better LF possibilities.

Thank you for the grafs Dave.
I appreciate it very much.

Is the Visaton FRS 8 (params below) likely to work in the FH Lite? Anyone modelled it, built one, or willing to guess?

Rated power 30 W
Mean sound pressure level 82 dB (1 W/1 m)
Excursion limit +/−2,5 mm
Resonance frequency fs 120 Hz
Magnetic induction 0,8 T
Magnetic flux 200 µWb
Height of front pole-plate 4 mm
Voice coil diameter 20 mm
Height of winding 4,5 mm
D.C. resistance Rdc 7,2 Ohm
Mechanical Q factor Qms 4,85
Electrical Q factor Qes 1,32
Total Q factor Qts 1,04
Equivalent volume Vas 0,9 l
Effective piston area Sd 31 cm²
Dynamically moved mass Mms 2,5 g
Force factor Bxl 3,2 T m
Inductance of the voice coil L 0,9 mH

Fs is kinda high, it will likely need a lot of stuffing and bass (well bass as low as the FH-Lite goes) will likely be elevated.

Thanks!

A little late to the party, but FWIW, both the 8ohm & 4ohm versions of the FRS8 will work fine, especially if you have a corner to load it. The FRS8M with its larger motor will also work well, but may benefit from slightly resistive wiring. All three should be quite nice, especially for the money.
