There are others that reach 117-118 dBs(Again running flat).
Nice choice on the submersive and a worthy and major upgraded from your HSU sub. Congrats!
I used to own those Klipsch THX subs and they do or did sound great back then and looking at what the Rhytmik does compared to the pair tells me something is off a little.

Thanks, definitely the best upgrade I have done. Reading all of the threads on high efficiency speakers, dynamic content and the GTGs have been the most worthwhile reading I have done for figuring out what to purchase and where to spend my dollars.

It is really simple, if you want reference or a very high dynamic theater there a only a few options to chose from. Commercially you have CHT(I believe they are staying open), JTR, and seaton. Other choices are Danley and yorkville. JBL pro are great but huge so only a few could use them. DIY and DIY kits are another way as well which requires time and energy but you save big time as performance goes.

Yeah I don't know all of them. Might as well add power sound audio to the mix as well for cheaper subs too. That XS30 should be awesome.

The above comments bring about the question, how loud does one need to go?...  The point, when is loud, loud enough and when is loud just spending money?...My question is a curiosity question as I'm sure the ego would only be happy with the 18" subs.
I don't think it has to do with they money, or size of drivers. Unless thats what matters to you. It should be about your application. Can your main speakers handle the volume you wish to play? How loud is that? If not, then you already have a bottleneck.

If you're at -15 now even -7 would be a big improvement. If your FR is dippy another sub would smooth it out and you'd enjoy the level you're at?

Some prefer the SHO-10 to the 888LP so who am I to say they are wrong. I liked my 4 SS 18.2's better than the dual Cap1000's which were the same price so why not.

The OP is talking about a single sub and not muliples. wink.gif

In this case, it's a case of WAF meets macho male expectations; quality, drum pounding bass that shoots right through you while blending with the room decor. At times I can be a cretin yet have no problem with this type of conflicted personality. My wife on the other hand suffers from sensitive hearing and anything over -10 and she starts holding on to her temples. In this case, it's about both, my wife's sensitivities and my need for sound quality.

The main speakers can handle 250w continuous and 1000w peak, so no bottle neck in the mains as the speakers are easily capable of reference level sound. The room acoustics associated with the subs are dialed in using a DSPeaker, Anti-Mode, 8033S II and the AVR provided for Audyessy, MultEQ XT. After EQ'g, the subs are final adjusted with a sound meter. Unfortunately, the room and furniture size limits the room to two sealed subs.

The current subs are eighteen years old and designed for another era; early 1990's with a peak level of ~107dB. Of course, this is short of full subwoofer THX reference; 115dB. The intent of the introspection is to decide if I "need" 18" subs or am I throwing away $800.00 as the outer appearance of the sub boxes (18" vs 15") are identical.

For just one sub, I pick the DTS-10 kit. Digs low and hits reference outside at 20hz, piece of cake indoors.

It is still king at Data-bass for commercial subs. It wins from 12hz on up as spl is concerned. Until JTR and Seaton are measured by Ricci it remains on top for me.

It's too bad that the last bunch of films are lacking in that department.

We can't control that so I just take what I can get. MOst good movies lacked great bass anyways and the less than great films had all the great bass. I still enjoyed watching Avengers and TDKR. At least there was something to feel unlike Battleship.

It was a pretty good action flick with a good soundtrack. Had some decent bass but wasnt' blown away (my wife had her friend stay over so I couldn't listen at reference). The audio dropped out twice and came right back on but I heard of other people having the same problem with this disc. Interested to hear how your system sounded with it being as my two HSU VTF 2.4s don't go incredibly low. They can't quite keep up with my SHO-10s but come close.I need to either sell my HSUs and start over and get two 18s or maybe just add an 18 to my current setup.
