SI HST 18 MkII with iNuke3000dsp

I was wondering if the inuke is suitable for my home theater use with my hst18 as the frequency response of amplification lower limit is 20hz but my driver is capable of 14hz. Should I choose a different amp or would I have to install something in addition to the inuke to get the most out of my sub?

The inuke has no problem playing to low frequencies, but to implement DSP below 20hz takes a little extra work.

That said, that driver is wasted with an nu3000 powering it.

Would you recommend an inuke6000dsp?

Not really. It's basically a pair of nu3k's bridged with a weaker power supply. You'd be stuck running it on one channel at about the same performance as the nu3k, since the lowest impedance it can handle is 4 ohms.

Something like a prolite 7.5 can support 2 ohm loads and put out a lot more power. Burst to about 7.5kw and sustain about 5.3kw. You'd need some external DSP, though.

All that said, if your constraints are not space / sub count related, you'd be better off with a pair of um18-22s over a single hst18 by a good margin, and it would be cheaper. If you already have the HST18, get a good amp. The prolite 7.5 would be my rec if you don't need to worry about fan noise. Otherwise, the SP1-4000 from speakerpower is silent.

If amp can be isolated in another room, a FP14000 is also a good option. @notnyt did you ever get around to testing/measuring a FP14k or FP10k?

Yep. The smiths (botai) fp14k is currently the best from what I've seen. It'll sustain about 4.8kw for a couple seconds, burst to around 12-13kw. This is a better option than the prolite 7.5, but I don't suggest it since it has obvious warranty and repair implications.

The prolite mentioned is also loud, but not as bad.

What about the FP10k? I believe one channel (FP10k) per HS24 is inadequate for my taste. Do you still have a FP14k? Sorry for the highjack OP.

I have a Smiths one sitting here I need to run a full suite of tests on. I just did a few quick high output tests since that's really what's important. I'm using SP2-12000s in my setup now. I haven't tested an FP10K. If someone wants to send me one, I'll do it.

Either way, 4 HS24s on an FP10K is spreading that amp too thin imo. A couple of FP14Ks would be better.

OP... The 3000 will not be able to drive the HST near its limit. It will do o.k. and better if the sub is in an overly large sealed or ported cab and you use the DSP workarounds that LTD has posted several times to push the filter below 20hz.

I ran a bridged 3000dsp into 4 ohm on a sealed FTW-21 for a year and had fun, even ran it on a single channel in 4 ohm for awhile. It will make bass and as a starter amp is not bad. Though, once I upgraded to a sanway clone fp14000 and a minidsp the sub just sounded different even at the same SPL and I had plenty of power to play with low frequency filters and such beyond that. I now use my original 3000dsp for some cheap auro bumshakers and it is still kicking 5 years later with a quiet fan mod and some additional heatsinks applied in a cold basement.

If you are low on funds it will make do, but just have on your future upgrade list higher output amp.

I love Not's amp tests. Best Amp-pron on the interwebs currently. I think we need to somehow understand how amps can sound different with low frequencies and when amps are not pushed to their max. How often are subs pushed to clipping all of the time? A decent system does not push the subs or amps to the clip lights (how accurate are they anyway) often?

So did you sell all your FP14Ks? Is the 4.8k per channel for a second with the Smith's FP14K? I can't seem to find the post showing the results for the FP14K.

That's total output. Yes, sold mine a while ago.

Ported 5cu ft hst-18 mk-2. Better choice than inuke6000 but not 1k like the clone. Outside my budget. Might get a um 18 later for my 2nd sub because of the cost of the HST enclosure and amp.

There is a reason Dayton Ultimax is so popular on here.

So I stick to what I know. I know inuke works, I know CrownXLS works, I know LG Clone amps work, but people can be slightly wary of them.

I haven't heard of that amp brand so someone may need to chime in.

Is this for the Ultimax?
An inuke works fine for that.

I wouldn't feel too concerned about LG Clone amps.

We got 2 big threads on them.

Also speakerpower is good on here, but I see that in more pricier builds as that's a pricey amp.

I've seen so many inuke/crown xls stacks on here it's hard to use something else, and I use both of these amps.
I LOVE chinese clone products (China is ruthless at cutting costs), so my next amp if I needed high power would be an LG Clone amp from sanway (or any of their amps)
Edit: To be clear, I see a lot of people wary of recommending china products because "warranty!"
As a person who would price/value a warranty on a company's bottom line...Normally a warranty is a great selling point, that never gets to be actually used. Extended warranty's are even worse. When some company's were making a profit purely by selling extended warranty's and even losing money on the sale of a product, don't get fooled by a Warranty. Only time it works is if a company has idiotic finance/actuary people.

That said, if you can't afford 2 of it, I generally won't buy 1 of it if it's from China.

Fp10000q was what im looking at for clone. Smith's is the vendor.
