Well... I can get it new for 160€ (197$) and with shipping it's at 190€ (234$)
Isn't that a nice way for a novice to learn about HT-subs or would there be better candidates for the price?

edit: I'm hoping someone could sim a TH, that's often a surprise and I have no experience with hornresp 😱

Because nowadays the majority of movies have not only a significant amount of bass down to 20 Hz, but increasingly more infra-bass down to < 10 Hz, so ideally one needs an IB with one or more high power handling, < 20 Hz Fs drivers: The New Master List of BASS in Movies with Frequency Charts

Thanks for link. But what is the sound content, freq curve, or whatever that makes a movie 5-star, 4-star, etc?

Do you have a link or thought about extending down the infra-sound even if that "violates" the ancient "400,000" rule (lowest freq times highest freq should always remain 400,000)? For example, to keep to the rule, a system would have to be 10-40,000 Hz... which doesn't make sense.

The 400000 rule doesn't seem to make much sense - it seems to operate on the assumption that we hear 20Hz-20kHz, and that if you lose some at one end, you should lose some at the other, presumably to keep it sounding balanced.

My speakers go to 40Hz, so the 400,000 rule would indicate they ought to stop at 10kHz.
Seems a bit silly IMHO - 40Hz-20kHz is sufficient for most material, apart from (apparently) movies.

You're welcome!

I haven't followed the thread, but it must be there somewhere or else human nature being what it is, there would be no consensus.

What can I say? As you probably know, the ratio was originally 500,000, which was later adjusted to 400,000 to account for the slowly increasing BW of sound recording/reproduction systems. Today it would theoretically be more like 10x lower [1 - 40,000 Hz] if we were to follow it, so apparently doesn’t make any sense for choosing a system’s total BW.

As for going lower, I 'chased' going ever lower since I learned early on that in each case it added another layer of 'weight'/'fullness'/'richness' to the reproduction plus it can trick one's hearing into making it sound more extended/'open' than it actually is in apparently the same way as we can 'fill in' the lowest missing fundamentals somewhat.

For me, the latter falls well short compared to the former WRT ~life-like reproduction and must for most folks since they complain about the lack of bass yet never about the HF roll off designed into cinema sound systems to ensure good speech intelligibility.

I'm prepared to say the 400,000 rule was a meaningful rule of thumb in the sense that systems sounded better to me with that kind of top and bottom balance in times past.

For sure, (1) the number is arbitrary and (2) with the improvement of technology taste may also shift making the whole multiplication concept unhelpful. Also (3) changing the terrain of enjoyment is the fact that we are already able to produce sounds to beyond hearing limits and (4) now getting into infra-sound.

So maybe we have answered my question.

Thanks for the quick responses everyone.
An honourable member of this forum sent me a PM to let me know there are cheaper drivers nearby my place, like three drivers for the price of this one 🙁
So now I'll try to convince this ebay member to stop the selling of the Kenwood.

You're making me want some proper subwoofers now - my little speakers stop at 40Hz (ported). I can block the port and boost the low end, but I don't think even the 6.5" TB "subs" could reproduce the experience you've mentioned.

The problem is that, all being well, I'm moving into university accomodation in September, so a few IB 18"ers wouldn't be an option. Curses!

Something to look forward to, I expect, when I get my own place.

PS - probably a little off-topic, but can anyone recommend some PC software, that has a decent graphic eq, for watching movies?

If you're happy with 40 Hz watching movies, then I imagine you will get a significant enhancement using a very low Fs woofer in a LRT sealed cab even if the bottom two octaves are fairly quiet, especially if you can work it out to be close to you, like under your desk.

I guess it will just depend on how well the rooms are insulated sound wise.
