"Anybody want to speculate on how it did?"

what the heck...i'll guess transient response is unremarkable, a little top end rolloff, otherwise not too bad.

qc issues and availability, who knows.
post #153 of 2212
I dont think the impulse response will be better than the Dayton 18HO, but it will probably have a little more output from 30-20hz and down.

Oh nice! About damn time, pssshh.. rolleyes.gif Jk tongue.gif

I predict that it will have an overall output capability similar to the new Dayton 18HO but maybe a little extra sensitivity down real low. Maybe more of an inductance hump but not too large. No where near that of the Fi motor drivers but maybe a bit closer to the UXL or just worse by a hair. Compression will be higher above box resonance because of the small diameter voicecoil.

*sigh*

What else? biggrin.gif

Should be a nice alternative and a good buy for those on the cheap. I'm sure that will be the endgame.

Based on the smiley face, all I can speculate is that it did better than the haters thought. Let us know when the data is posted!

By haters you mean the people who put the T/S parameters with the 3 element Le model into their software simulation and said, "Eh, this doesn't look very good." right? Such terrible people...

I was referring to Scotts simulation software.

Lol!

I have been faaaarrr from a "hater" of the SI HT18. The only thing I "hated" on them is that they are unavailable. All they are as of right now is a promised product.

Haha, I wasn't player hating on you brother... NEVER!

Actually my comment wasn't directed to anyone at all. Nothing but love to all of my AVS crew!

I'm working on getting this stuff up. My laptop has taken a crap on me and that is what I usually use. My pc for testing doesn't have an Internet connection because the wifi cards always seems to interfere with the audio.

Long story short on the 3 part LE there is one decimal place off in the LE. It should be about 1.3 not 13. I cannot recreate the export difference that I know I saw on the computer I'm using and I can't go back and check it on the laptop until I get a new power supply and battery in. Sorry about not catching that and the mass amount of confusion that caused. This should be closer to reality but there will still be some differences in the model vs real.

That certainly changes things. Your corrected measured T/S parameters give in box responses that are within 1dB or less of the SI T/S parameters from 100Hz down. cool.gif
post #162 of 2212
Much better.
post #163 of 2212
Looks good Ricci ! =)

From the corrected T/S's Josh recently posted (BTW: thanks for posting the corrected results) along side the obvious design criteria of the woofer I would have thought that some of the people in this thread would have at least thought that the initial Le figure might be a bit off from what Josh first posted. Unless the D2 2.5" coil with an Re below 4 ohms that SI uses was over 3 inches long the inductance wouldn't have been that high. But it's stated on Josh's web site that the coil is 1.7" long. Why didn't anyone question the high Le figure for such a small coil instead of bashing the woofer because of it?

It's interesting to see what people nit-pick about without looking further into the complete data and maybe asking questions instead of jumping to conclusions. To me this woofer has over 50% more linear displacement than the Dayton for a lower cost. And with these new/corrected Le figures I think the SI is the clear winner here

that may be the clearest case of the pot calling out the kettle for being black that i've ever seen.

why don't you ask how it is possible for the dayton to produce such large amounts of excursion limited bass with the specified xmax before comparing the manufacturers' ratings on the two drivers and then proclaiming a winner?
post #166 of 2212
Not to interrupt this stirring discourse currently taking place but...All the measurements are up. Bon appetite!
post #167 of 2212
Thanks Ricci
post #168 of 2212
thanks ricci. i admit the stiching on that first one didn't inspire much confidence and most drivers in this category have inductance issues, but the results are in and they look good. congrats si.

16hz, it appears the difference in xmax for 20hz performance is about 22mm dayton, 27mm si.

Full review is up on Data-Bass.com!

Pretty good results! Quite literally what I expected out of it. Models extremely similar to the Dayton HO18 (unless I forgot how to read the results rolleyes.gif ) so those who didn't wait for the SI should not feel bad.

Inductance related ....whatevers... is very good too. smile.gif The distortion profile on this guy looks incredible!
post #170 of 2212
I'm looking at buying 4 of these...would this be a good choice for a HT room of 18 x 15?
Thanks
post #171 of 2212
Absolutely.
post #172 of 2212
Thanks,

Would it be ok to put these in a 3.4cuft box? I already have these boxes.
Would this be limiting the subs in any way?
post #173 of 2212
Yup and nope. smile.gif
post #174 of 2212
Scott,

Thanks for helping a newbie out
post #175 of 2212
Heheh. No problem. smile.gif


Argh! Now I want to order four of these, myself. redface.gif
post #176 of 2212
Life is good
post #177 of 2212
Yeah. Now maybe all the super sensitive fanboys of this can feel better now. tongue.gif
post #178 of 2212
Does anyone recall those threads a few months back about there being no budget HT sub alternatives anymore? Things are looking up all of a sudden.
post #179 of 2212
Nice, Josh! Great work as usual.

What is the availability on these looking like? Here are my thoughts vs the Dayton.

SI pros:
Larger displacement with a few db more output
Slightly cheaper cost? Although I don't know what shipping wil be.

Dayton pros:
Larger voicecoil
PE service and outstanding warranty support
Higher rated power handling although real world is probably very similar
Availability

Thoughts guys? I love having so many budget DIY options around!
post #180 of 2212
According to their website, they should start shipping on the last of the year, but we know how that goes.. Currently $190 shipped, but that's the pre-order price.
