Anyone has experience with Seas W26FX-001 woofer? Is it suitable to be put in a 50l seal box? I'm looking for a 10" woofer that is fast, tight and low distortion, handles from 200Hz and below, but it doesn't have to go very deep. A friend of mine suggest Lambda SB10 or SS 25W8565-01, but I saw this new woofer from Seas. Please share your thought with me.
Thanks,
niner

Never thought I say this but...I wish I could give you first hand on this driver! If you can afford it, and you have enough crossover experience to tame the breakup; yeaah baby, do behave!!
ps- I realize this may not help much, but the labatts combined with the want of this driver and the lack of sun pushed me over the edge.

It is awefully hard to beat the Lambdas. Especially if they are still on sale -- BTW looks like Lambda may not be closing there doors 🙂 -- the LE10 are still listed on his site for $79 USD each !!! cheap, cheap, cheap.
I am angling for a set of 4 of Nick's 10" -- i am going for SAL-SB10 from Stryke. These will go into a pr of push-push TLs.

I'm happy with the W26
I have one W26 for testing that's showed good results in a TL (even though you indicate you're not looking for the real low end). My goal for the unit is for a sub rather than a bass driver. I'm assuming that I'll use if from 80 Hz and down, or whatever works the best with my system in the end. The breakup modes are truely horrendous and I'm sure they'll need to be notched out.
From a spec perspective, there's a couple things I like about this unit. It has a low Qms and a low fs but a reasonable Qts for TL use. A lot of the auto-type sub drivers you see have enourmous Qms values. Being highly mechanically resonant doesn't make sense to me if you are looking for a taught result. Just my opinion...

Thanks a lot guys.
Do I really have to worry about the breakup, even though the crossover point is at 180Hz, with third order low-pass network? But I understand your comment of getting this woofer to sound "tight".
Lambda is great, although I worry about not able to get replacement unit a couple years from now.
What about the scanspeak unit? Any comment?

sry to kick this thread, but that Seas is on my short list as well (as is the Lambda).niner said:
I keep hearing about how difficult these Seas are to filter. At what frequencies does the breakups occur (and to repeat Niners question: what if your Xover point is below those freqs (say with a 24 dB filter)?
I would use them in a 90L BR, actively crossed somewhere between 250-300 Hz (If I would choose these units).
I really don't know much anything but from the datasheet http://www.seas.no/excel_line/excel/E0026.pdf
You can see that the breakups start after 2kHz. So with 24 dB/oct filter you should be able to go up to 500 Hz and you are atleast 50 dB below when the breakups start. 50 dB below should be enough. So with Xover at 300 Hz you should be safe with a good margin.
Advantages
Does anyone know if there would be any advantages to choosing this driver over two peerless 10 xls's in a sub or bass driver enclosure (I'm still designing...)?

Hi Philip,
the W26FX001 is designed to go LOW...
Klang&Ton uses it in a 65-70 liter closed box. For bassreflex you'll need about 90 liter.
With about 140 liter you can go as low as 16 Hz -3 dB!
2 XLS-10's? They won't go as low as the W26FX, but if you want a much bigger SPL than the W26FX, the XLS-10's are a good choice.
Another advantage of the W26 is the Mms: 79.1 gram while the XLS10 is about 135gram.
I haven't heard the ScanSpeak 25W8565 but in specs it looks even a little better than the W26: 47gr. mms, low fs.
Maybe the 26W/8861T00 is also a good alternative?

Hi,
Check out the Seas L26RFX/P. It is very similar to W26FX001, but has aluminium cone and missing the copper rings in the magnet system that W26 has. Same magnet and basket. Very high quality at a much lower price.
http://www.seas.no/seas_line/H1209.pdf
I haven't tried them myself, but I have 4 L22RN4X/P which BTW are very good drivers.

Regarding the W26 - the breakup will not be a problem if you use the driver as a bass driver, ie not above 300.
XLS they are great drivers go loud and can be pushed without producing any nasties. Very tight bass and tuneful in a 20l sealed cabinet Eq's f3 of 35hz. The bass is obviously very clean and low in distortion.
The lower dist is not as noticeable in comparison to a 850146 at normal listening levels, as in not that loud. But when u have to shift some air its clearly obvious which is the better driver.
I would also like to try the W26 but its horrendously expensive and an XLS is less and to me is better spec'd for a bass application. Obviously is depends on application, but for a small sealed box with EQ, or small PR box without the XLS wins my vote.
If I had to use the driver higher up mind you, say to meet a high quality mid driver at above about 150hz then id prefer to use the W26. Above 150hz is where voice and intrument fundamentals start to be produced so you want a good driver to reproduce that range, not a sub woofer.
Both I would say are excellent it depends on application.
If a low xover point could be used then I would go with the XLS simply because of the small box, im not a fan of fridge speakers.

I agree on that, the breakup is not a problem at 200 Hz. W26 (and L26) are excellent lower midrange drivers with low distortion.

I'm using the W26FX in a dipole and really, really, like them. Very clear and articulate bass...an "unspeaker" sound.
Crossover is 220Hz series 1st order to W22. The 26/22 "two-way" is then rolled off at 800Hz 4th order active. I can hear no break-up.
Of course without the filters they sound like you stepped on a cats tail!

I had seen those dipoles before and like the look of them.
Sound like ud stepped on a cats tail! 😛 haha. My w15's dont sound that bad without a filter lol.

Run L26 in simulation?
Sounds like the L26 are very good drivers... I'm wondering if anyone has run the L26 through a sealed box simulation to see how it compares to other drivers like the xls. Also, what's up with the HUGE vas of this and the W26? The consensus seems to be that you need a massive box to make them work well.
Also, is it ok to crossover a Seas W18 at 150Hz or would it be ideal to cross it over higher in a 3-way system?

Hi,
I know this is an old thread, but I'm interested in the W26FX as well and was wondering if anyone had any comments about the use of this driver in my application.
I have a very specific application. I have a pair of Carver Amazing Platinum "ribbon" drivers and I'm looking to build a system around them, but I also have space issues which means the four 12" open baffle woofers aren't going to work. In fact, the single NHT 1259 in 3cu ft. enclosure often paired with these ribbons is also pushing it.
My interest at this point is to use the ribbons for the high and midrange and then use W26FX from about 50 - 200Hz and a Sunfire EQ Signature sub from 50Hz down.
I plan to bi-amp and already have a custom active crossover (Clearview CRX1) for the ribbons.
The thing that really gets my interest is that I've read that the W26FX001 can be used in open baffles which matches the original design of the Carver Amazings.
It sounds like the driver can be used either in a sealed box design, or in an open baffle. Can someone comment on the trade offs, and performance differences with each?
If used in a sealed box, any suggestions for volume? I've seen references on the web of people using a 20L and a 30L box.
Lastly, any thoughts of using one or two W26FXes per side? The 60" ribbons can have impressive output, and I'd like to have a good match in the mid-low range.
Any other thoughts or comments?
Many thanks,
-john
