Looking good! +0/-3db 29-56hz with equalization, -10db@19hz in about 1 cubic ft. sealed box. All tests nearfield with the O Audio 500-watt amp.

I posted my tests awhile ago in the driver testing section of the forum, but just in case people were interested in seeing the results here as well:

Impressive distortion as well. Seems like you could cross it over pretty high. How's it sound compared to the others you've tested, Jed?- Bottom

One word. Amazing.
This "sub" does it all. Allows high crossover points, smooth response, low distortion, plenty of xmax, and most importantly it sounds great. They go very deep in a sealed box, which is how I'm listening to them right now (ported they will play in the low 20s in a small box). They are also fairly sensitive which is a huge plus if using them in a 3 way speaker.Last edited by Jed; 22 June 2010, 20:59 Tuesday.- Bottom

Most of my measurements below 200hz include nearfield data spliced in. This isn't a farfield in room response with low resolution depicting room gain.- Bottom

I do wish it was black. Other than that, it looks pretty ideal.
Hmm... L26ROY, a pair of SB15NRXC30-4s (when they are available) and a SB29RDC (or, perhaps, better yet - SB29RDCN when they are available). A "poor man's" Aria10?- Bottom

Anything is po$$ible. :W Seriously, I have a list of speakers to develop and something like that crossed my mind.Last edited by Jed; 22 June 2010, 21:01 Tuesday.- Bottom

Nice. The one thing that has always held me back from Tymphany based stuff is availability in the future. Pity, because a lot of the drivers they make are very good...
Hopefully with the new reorganization of the lines things will turn around. I have my fingers crossed.- Bottom

To Jed and Rick:
How high do you feel this can be crossed over when used as a woofer instead of a subwoofer?- Bottom

I'm seriously considering this driver in an upcoming design, but I want to know how high in frequency can it really go.
The graphs say >1 kHz, but that says little about how it sounds. The nearly 100g Mms has me concerned.
I need a driver that will do 1st order at 300Hz so it has to be able to do vocals extremely well. Jed, how high are you taking it?- Bottom
Comment

I haven't tried them first order, just 2nd or 3rd acoustic around 300-400 Fc. If you look at my HD plot there is some higher order products that you'll want to avoid around 750hz, so that will definitely be more audible with a 1st order acoustic slope.- Bottom

It's pretty hard to find any driver, especially one with a really stiff cone that will hold up to 1st order filtering.- Bottom

L26 + passive radiators
I noticed on the Seas web site that they now have passive radiators designed for the L26. Has anyone tried a build using them and/or does anyone have an opinion of the possible results?- Bottom

Nice work David! ;x( ;x( What drivers and crossover type (first order?) did you use for your mains? What do you think of the sound?

Whoa, just what a fellow would need to create some lease breaking mini-subs! Say, the Dayton 2 cu ft, which would supply enough volume to allow for that subtracted for the driver and PR volume.

Passive radiators are similar in function as a port but without the noise, and it allows the driver to work in a smaller volume where a port would otherwise have to be too long. So dual L26ROYs in a sealed box would go to the same F3 as a single, given the box volume is exactly double. Therefore, the L26ROY with one passive will go lower in the same size box as a sealed sub and using two passive radiators will increase the excursion capabilities.- Bottom

Hi Jed.
Thanks for the clarification in re: to two active drivers in a box double the size of a single driver in a sealed box, but having 6dB extra output. I also understand a little about PR systems. eg. tuning PR's based on ported alignments.
Most people seem to use 1 PR, or a single PR of a larger size. Less often I use two PRs mated to a single active driver.
What I'm trying to figure out is the displacement requirements of the passive radiator. What is this a (mathematical) function of?- Bottom

You can model the T/S parameters of a subwoofer to see how X volume with Y number of passives will work in the intended volume and how the properties of the passive (adjusting the mass... etc) will hit the desired tuning. The advantage of using dual passives is that you can have greater SPL capabilities before running out of usable excursion. So depending on how loud and low you want to tune it, you can decide if you need 1 or 2 passive radiators. Unibox will give you all you really need to design a proper box using passive radiators, and if you do end up going with the L26ROY, Seas has a recommendation for using 1 or 2 passives on their website.
