In a small 2-way like the Overnight Sensations it probably operates a lot like... the Overnight Sensations... with a different color cone, a little more sensitivity and a little less low end... and that's okay.

Indeed. People need to have realistic expectations of differences between similar SD drivers, it takes A LOT more clean excursion to play much louder driven full range.

I will say though, that at ~2x the cost of the B4N/M4N in the overnight sensations, one would hope these perform significantly better in some other aspect.

Well, SIG serie will soon come to europe. I wonder if they can compare to Seas Excel?
Is the quality good enought?

Obviously the build quality is not going to be the same as a Seas Excel woofer.
I mean, you pay a price difference for many reasons.

I expect the quality to be around Dayton RS series/Peerless (since the basket is the same as Peerless)

A friend dropped off some sig180's yesterday, he's a user here so I bet he'll see this.

They are very pretty in person, combined with their performance and price these seem like the go to woofer for a lot of projects, but we'll see what they do in a speaker box. These will be put in a two way with a wg300. I thought the print on the back was just a sticker but it appears to printed on in some manner, just an overall visually well executed driver.

Does SIG-180 work in a 2 way BR?

Of course. There's nothing unique about it in terms of its basic LF characteristics -Fs, Vas, Qt are all suitable for vented box loading. Based on the published values, and assuming
  1. About 1/2ohm series R to account for typical wire loop resistance, series inductor DCR etc. (remember this raises the effective Q) and
  2. A fairly typical damping scheme & box leakage losses
Then 25 litres tuned to 36Hz or 37Hz should be a reasonable compromise, with a lightly damped alignment. If you want to go old school, Vb = Vas, Fb = Fs should also be a (slightly higher gain) baseline under the same assumptions. Equally old-school, if you want smaller, Vb = 16.1 litres, Fb = Fs under the same assumptions will also do reasonably -more highly damped, but OK for near boundaries or smaller spaces. For the filter & partnering driver, same as anything else, depends what you want, but the available data suggests it should be easy enough to work with / partner, so plenty of options available, from simple to complex if you want to see how much performance you can wring out of it. I very much doubt it will equal, let alone beat an Excel series Seas, or even, say, their excellent ER18RNX, but the latter costs about 2.5x the Dayton, and when the Excel series come up, you generally have to keep an eye out for your wallet sidling out of the door with a hitchiking sign marked 'Tierra del Fuego' around-its-neck. 😉 So you'd certainly hope they'd be better, taking nothing away from the Sig-180 which is looking to be a good unit for the money, and potentially punching above its weight.

I slaughtered an ER18RNX some years ago and found the coil length was between 19.60 and 19.80mm long , which is close to the 20mm length of the EXCEL series of SEAS . I did not check for any other differences , sorry ...

In my opinion the ER18RNX is an outstanding driver , but a bit pricey!

But the Sig180 could be a DLF kind of transducer 🙂

A non-conducting voice coil carrier has pros(less losses) and cons , some folks like it some don't . Any change in driver design will change the perceived sound , not always for the better!

Regarding cabinet - make a TSP based simulation and check the difference!

Room size/acoustics , speaker orientation/placement and your listening position - lots of options for improvements!

If the weather is fine , listening first to your speakers outdoors! You can even record the event on a storage unit , digital field recorders are not so expensive nowadays and microphones are included ... you can even make your own reference recordings! (you will be surprised how good they are)

This audio hobby has so many opportunities , lots of work for your brain too 🙂

I am very happy to have started this hobby around I was 13 instead of chasing women 🙂

But sometimes they are showing up in a very convenient way 🙂

True. I just always noticed that it was Wavecor, Scanspeak, SB among others that used to be high Qms, where Seas and Dayton were definitely in the very low end.
Some said it meant fewer losses and more detail. But I was also told that it wasn't that simple. So my question was more of the technical type- like why the Qms changed so drastically. I know that it might sound different, and that I have to simulate and maybe even buy one to check it out myself.
But thank you for the hint. 🙂

Nice video too 😉
