randomly noticed this driver in 16ohm variant has higher qtx that would seem to suggest it as a good candidate for a sealed box . would the higher impedance cause any problems other than drawing less power which doesn't really seem a problem ? lower sensitivity perhaps?
Hello.
Can one assume you mean the Faital 15FH500? As that is actually available in 16 ohm, and a existing model 🙂
The FH520 is also avail in 16 ohm but a higher FS and qts etc.
Generally good quality drivers, and well behaved, the 15PR400 too.
The xmax estimation tends to be on the generous side though.

excuse me yes that is the one I mean thanks . but the impedance itself shouldn't be a problem as such ?. I was planning to use in a three way with analogue active crossover
Would you be ok with reduced bass output having this unit in a sealed cabinet? Did you try simulating it? Sensitivity is based on 4Vrms input.
Well I worked it out using the equation 0.707÷qts x fs and it seemed good for sealed if the sensitivity is lower because of the impedance couldn't I just turn the gain up . or alternatively use two per channel wired for an 8ohm load . if I could get a 300 litre cab past the misses
If cost matters, Madisound currently has the the 8 ohm 15FH500 as an OEM closeout at a very good price.
When looking for sealed woofers, in that price range.
The 2 you linked have a large gap in FS/and sensitivity,
Depending on where you live and availability, these also might deserve consideration, if you have room for 300 liters+ cabinets. There is more 19s of choice in general for sealed it seems.
JBLS 2216ND, higher FS again and xmax more like the Faitals.
Fostex 405n, japanese made paper cone woofer, but limited on xmax again.
https://en.toutlehautparleur.com/sp...aker-davis-acoustics-39rpa15-39-cm-6-ohm.html limited xmax.
In terms of parameters for sealed these tend to stand out amongst the 15"s imo, but so does the price and lack of measurements.

Audiotechnology will makes you a custom low fs, "sealed" woofer to your desired specs, with mineral mixed poly or sanwhich cone, different voice coil tech, magnets of choice etc. With good sensitivity With some limitations ofc. But it will cost more then most options.
I'd love to go for an 18 then I'd just go bms 1852 and call it done unfortunately I don't know if I would get away with that in the living room as I live in my partners house . 15s don't seem big to me since I've owned one and I prefer bigger speakers myself . I agree about the ae woofers but they'd be expensive here in the UK and I wonder if they live up to the hype . when you say a large gap between the fs and the sensitivity what exactly do you mean please I'm not sure I understand you correctly
I'm not too sure that xmax is the end all be all. Just a for instance, take the 15pr400 and the 15fh500. The latter has twice the stated xmax but it equals the 15pr400 xmax an octave higher in frequency. So, distortion would also start an octave sooner as frequency drops off. Not sure how much SPL the OP loudspeaker requirements are but I'd try to consider how well behaved the woofer is vs the stated xmax. A simple baseline sim comparing the woofers available to you could be helpful in that regard.
I meant that the SB woofer has a FS of 18, rated 93db , real 90-91 db. 11.5 mm xmax.
The 15fh500 is rated 97db, 35hz fs ,almost a octave higher, and lower xmax.
So they will be quite different in character.
The first one being more of a traditional 'hifi sub'.
And the 15fh500 being a higher efficiency pro, woofer/midwoofer.
Faital tends to offer very good bang for the buck, low le, low fs( for pro woofers), shorting rings in some, well behaved and damped cones with good efficiency.
The selection of a single 18 vs a double 15 is the option i had in mind when i mrntioned it. Is not the right choice for every situation, it just opens up more ootions in driver from the 'pro' segment as they offer efficiency with a naturally lower FS, closer to he likes of the sb42.
You did not put down a lot of parameters except for suited for sealed use. The more info you give on the intende range for it to cover,and what you want to integrate it with ontop, srtting practical upprr limits. And required spls defines xmax/vd needs.
Some drivers works okay with low power tube amps. And some needs hundreds of solid state watts to go loud.
Like the bms 18n862 indeed, again a different and very good driver, but needs a lot of amplifier muscle in a sealed config.
And yes the AEs are expensive to ship and export, so the value is not the same as in the US. But they are one of the few mfgs. That have really nice woofers suited for sealed applications judging from parameters.
The AT would be similarly priced from Denmark fx, pros and cons to both.

That SB42FHCL75-6 plays bass 10 Hz lower (F3=44;F6=32;F10=24) in the same 120 litres sealed cabinet than the Faital 15FH500-16 does.
Better candidate imo. 👍

yeah good point Im interested in the sb I'm just looking for cheaper options to the sb hence asking about the faital
Well I was after a bass driver for a sealed 3 way I have a couple different options for the mid and highs either a bm15 passive bm15 active or the fane 15300tc making it a 2way or a couple other things I have lying around . I wanted to use dsp crossover but can't find anything that meets all my needs ie xlr output . so most likely will use the xkitz electronic crossover with j river to find the perfect crossover points etc
