It depends on setup, if you have a 4 ohm load the clone in bridged mode will blow up the driver. Matching impedance and power is key for proper setup. Some say the new sanways are 2 ohm stable but we need some testing for sure before we go nuts. I am running 8 SI 18's off of one channel in 2 ohm load and the other 4 off the other channel with a 4 ohm load. The key is design and how many real watts at what load is actually needed.

Of course.

When I had the clone amps about 3 years ago, Sanway was clear that the clones were not 2ohm stable, so attempting it didn't make much sense.

The clone in a 4ohm bridge is to much power long term, but i guarantee i could still clip it at 50hz and up on drum kicks without hurting that B&C driver.

Might want to also consider the SI-HST18. It has higher maximum excursion capability. So when the UXL-18 is at its absolute max output level and is starting to bottom out and make noises, the HST-18 will produce that output with excursion left. At least, that's my understanding as I have been researching what the best mid-priced 18 would be for a 4 ft^3 sealed enclosure. Now, the first graph on data-bass makes them look very similar, but when you read closely you will see that the UXL was starting to complain at that drive level, and the HST-18 had several more db's in the tank before running out of excursion. Look at the max long term output before compression and the difference starts to show up.

Yeah, but unless Nick will be doing a "Group Buy" on the HST18 that the UXL18 is going for, I think that's the reason Brian's going the UXL route.

Personally I'd go with the Zv4/HST myself, but these group buys only come once in a blue moon

It is called a higher x-mech. I am impressed with the quality of the even the SI-18HT.

Time to estimate a couple of more subs' ULF performance:

Triax T-18
Reaction Audio PS-18x

Similar to the Chase Subs, the T-18 run a variant of the Eminence 18. Perhaps a starting point would be 3 Chase 18.1 (or 1.5 18.2s)?



For the PS-18X, perhaps similar performance to the UXL?



Thoughts? Sounds pretty reasonable to me.

I tried this calculator but it seems not to work on multiple subs. Unless I am doing something wrong.

What are you trying to calculate? I can do it for you.

room size?
subs?
quantity?

It does work for multiple subs. Just put the number of subs in the yellow cells to your corresponding sub, and it should calculate your score.

That's an easy opinion to have if you've never used or heard the UXL's in person. The simply fact is 99% of the guys even buying the UXL's from the group buy won't even be pushing them hard enough to even get close to max output. And in a sealed box you won't be pushing them to full excursion with an iNuke amp so you're not going to hear any bottoming out or loud noises.


In my ported cabinets my house started to show more stress then the UXL's did when really hammering them. I think the simply fact of the matter is that most guys using UXL's will be amp limited rather then driver limited.

Wouldn't three Chase 18.1 have large cabinet volume which would increase the really low end numbers compared to a Triax-18? If the cabinet of the Triax-18 is smaller it would have a little less output in the 10hz & 12.5hz ranges.

Brian, that was exactly the same thing that I did this time last year!....lol
Total deja vu, if you have the space you should serious consider building ported cabinets like what I did.


To give you an idea of the output difference between four sealed UXL's and four ported ones like I built in your room, here's the ULF score you'd have


Sealed:
286 @10z, 267 @12.5hz, 250 @16hz, 267 @20hz .


Ported:
444 @10hz, 154 @12.5hz, 78 @16hz, 182 @20hz .


That's a really big difference in the 12.5hz to 20hz range.

Yes, but the T-18 offsets the small cabinet size with the high powered plate amp.

Haha nice

Well im starting small with only two to add to my xs30's. So I want to stay sealed. Then I will build two more if the first two are to my liking

I don't follow your comment re max long term output. The long term data on data-bass says that the UXL has marginally more long term output <22Hz, marginally less til 35Hz and then ~3dB more through the mid bass. It looks to me more like they have similar output overall but the UXL needs less power to get there & the HST can take more abuse.
