I would not expect it to be significantly different than the 4 ohm. If anything, a bit better (in the direction of less inductance that is.) Reason for that is you typically drop wire cross section going from 8 to 4 while keeping the same number of layers. The gaps on the 8's are normally tighter as a result.

good to know!

Which is more blinding for you? the forums or db.com?

@peniku8 Interesting. i dont have an iphone, so I can't check, but try this. Go here: http://data-bass.ipbhost.com/notifications/options/ Turn off "play a sound."

Cool stuff!

Awesome video @Jeff Permanian, thanks for sharing. I see the TC Sounds 18" frame 😉 Dead right about high excursion + good sensitivity, I think you're figured out that threading that needle you do get the best of both. Nate's drives along those lines too.

Its not so much the size, but most pics don't need to be too big, Maybe delete older ones you have uploaded in your profile but also what greatly helps is saving photos as a jpeg with a reduced quality. Really large photos can be just a few hundred k. http://data-bass.ipbhost.com/attachments/

Nice job with the bend!

roger that, I gotta do the mobile css thanks for posting that @dgage

This driver is nuts! I need to see this thing run against the 24vU https://www.harbottleaudio.com/24vu.html

I asked an engineer at JL about 2 months ago for a Gotham... somewhat jokingly (I think its $13,000 or something) negative on that unit so far.

Sure, by no means is this wrong and everything on the y-axis is relative so it does work, just means means its windows to a set of dB that makes sense which is already done. Josh has wanted to add this data to the site for a long time now, maybe its time to get it baked in

I really like this idea and concept of comparing output vs size. I think one shortcoming with this graph is that SPL is on the decibel scale which is not linear, but we can think of box volume as linear. What we should do is convert SPL to Sound intensity (assume sea level for air pressure -- close enough). Once we have a linear scale for output and a linear scale for volume, I think the graph can have more meaning.

Seems reasonable, too much is never a bad thing either, just means it won't clip.

Awesome build!

Is there a US distributor for the 214.50 ?
-
wow! Based on the new sealed system max output tests that Josh just posted it looks like it outright beats the B&C in the midbass region and matches it everywhere else. Both of these drivers are beastly... https://data-bass.com/#/systems/5d02b177d6b2560004ebe49e?comps=5d03f339d349e90004d8fcd5&_k=ok0919

Your idea about the "perfect" pro audio subwoofer driver
Kyle replied to radulescu_paul_mircea's topic in Bass Gear
Looks exactly like the older Eclipse Ti subwoofers made by TC sounds, but that Qes is very high so that would be sealed box type of woofer. -
20 is way more than it needs, but keep in mind, the size of the box will help the size of the port. Almost all ported boxes are going to experience compression with enough power. A 20 cubic fox tuned at 20 could have a very large port compared to a box half the size. The hump is going to flatten with compression at higher volume. If you have the space, bigger will be better in this regard, but how much it helps will only show at higher power levels at around tuning.

Make get some ideas from Wisdom,. they specialize in in-wall solutions. TC used to make their drivers for the subs. https://www.wisdomaudio.com/ranges/sub-woofers/

RIP Tom, but this reminded me of his IB https://web.archive.org/web/20120617055921/http://www.nousaine.com/pdfs/Subwoofer that Shook the World.pdf

Normally when subs break things is a resonance dance. -

I would like to see the MAUL with 4 K20's on it. We would need a 600 volt feed from the power company at least. -
Your idea about the "perfect" pro audio subwoofer driver
Kyle replied to radulescu_paul_mircea's topic in Bass Gear
I'm just so picky about Qes, I wouldn't consider the SWR-12D2 for pretty much anything since I like small boxes. I honestly still like the god damn Lab-12C, but it does fall show in xmax. It would have to have more magnet to maintain its SPL / Qes if xmax was to increase. Eminence, give us a Lab-12 Ultra please! 1.8ww coil, 7.5" magnet We had a prototype TC-9 exactly like that (used a 3" coil of course, not 2.5") and that thing hard with 1000 watts - pro cloth surround. About 1.8" long coil -- not expensive by most accounts. -

Well, lets ask it this way, will this thing beat 2 Skhorns? Its bigger than 2.
