Also, why is there a significant difference in THD ratings on the amps? 18.1= 0.15 THD vs 18.2=0.92. I realize at this point im probably splitting hairs however I figured I'd ask.

Also, my room would be smaller than the recommended 20+ length room for a 18.2 sub.... would this be overkill in a smaller room? Also, would I lose the benefit from the natural roll-off aspect (23Hz, 12Db Octave) given the smaller room?

One last thing and this comes down to the fact that im trying to decide between the Empire or an 18.1... or maybe even an 18.2; why are there no picutres of these subs on the TCA website? Unfortunately I'm a huge visual person and would like to see pictures although the only ones I can find are the occasional pics posted on the forum.

Note that there is the CHT forum and the CHT product site.
The product site (as noted above) has pictures.

Someone else will have to answer your technical questions...

Even the forum has some photos. In the "Product Announcements" section, there is a sticky thread titled "Product Photos."

Hi - The reason you don't see pictures currently is we are in the process of switching over from CS-18.1 series 1 to a series 2.

Mike_WI posted the few pics of the series 1 versions of both subs. Thanks, Mike !

The series 2 versions of both subs will have upgraded finishes. We will have them in our factory next week, and pictures will be done ASAP after the enclosures arrive.

The 540 watts for the CS-18.1 Series 1 is a plate amp rated at 540 watts into 4 ohms. This is the only subwoofer which offers this amp.

The 950 watts for the CS-18.2 (the CS-18.2 series 1 and series 2 offer identical performance, the price difference is completely due to to a better finish on the series 2) is for the SA-1000 rack mount amp from Dayton.

This amp is rated at 497 watts @ 8 ohms and 950 watts into 4 ohms.

Any "single driver" 18 inch subwoofer system from us will be an 8 ohm system.

Any "dual driver" 18 inch subwoofer system from us will be a 4 ohm system.

The CS-18.1 series 2 will use this amp - and the driver will "see" 497 watts as the series 2 subwoofer will also be an 8 ohm driver.

We elected to use this amp on the series 2 single driver sub because one can double the performance by simply adding another of the 20x20x20 inch enclosures, essentally upgrading the CS-18.1 series 2 to CS-18.2 series 2 performance.

This also allows for placing the two boxes together for max output or in other areas for smoothing out the in room response.

For now ... here are the series 2 choices:

CS-18.1 Series 2 = 1 20^3 enclosure with the Dayton SA-1000 amp @ an MSRP of $898, and the amp is 497 watts RMS.

CS-18.T = 2 20^3 encolosures with the Dayton SA-1000 amp @ an MSRP of $1396 and the amp is 950 watts RMS.

CS-18.2 Series 2 = 1 40x20x20 enclosure with the Dayton SA-1000 amp @ an MSRP of $1396 and the amp is 950 watts RMS.

If this STILL does not make sense, drop me a PM, and we can chat on the phone. I know it's a lot of info to digest.

I was thinking...one of the things that could make a cleaner look for the 18.2 is if you made the grills go top to bottom. might make a nicer look..just a thought. and piano gloss finish as well.
post #515 of 689
Craig, what are these upgraded finishes? I just read all 18 pages of this forum over the past 2 days as Im late arriving on the CS sub line, but rather interested. All I saw on the website was " It now boasts the same finish and clear coat as the rest of the Chase HT subwoofer line and matches our High Efficiency Monitors" Does that suggest some sorta gloss blk finish similar to a piano blk finish?
post #516 of 689


Ok, pictures more than 90 pixels across
post #517 of 689
Oops, didnt realize there was a page 18 yet with answers to all the questions. Thx for the links to the pictures, this clears things up.

Also, thanks craig, I do appreciate your responses.

Not a piano finish at all. The Series 1 subs have an alligator armor finish that is slightly pebbled. Nothing extreme. The Series 2 subs will be a smoother black with a clear coat finish which matches the HE Monitors.

Any chance of some piano blk in the future .

Reading through the forum I believe I noticed a couple different members mention they had two CS18.2s....... I was curious for those who have two in their set up, are you stacking these MONSTERS or atleast co-locating the subs. Im considering getting two of these to replace my single DT Trinity. I was thinking I could put one the front left corner where the Trinity resides and put the second in the back right corner opposite the other C18.2. However if I dont place the second CS18.2 next to the other one I wont be maximizing the potential of the subs in terms of spl.

What is the size of your room?
Do you think that even one CS18.2 would not have enough SPL for you?

Co-localized - higher SPL
Non-co-localized - smoother response

I think some people might be getting even more and doing both co-localizing and non-co-localizing.

No immediate plans for piano black. But, with Craig, ya just never know.

My room is 26' long, 15' wide (at narrowest) and 17' wide (at widest) and 8' in height. I currently have a DT Trinity which I believe puts out a significant amount of bass, and I'm very happy with its performance but the upgrading never really ends. If I switch to a new sub(s) I want something that is going to be a considerable increase in SPL. I attached a modeled picture of the room.

Im guessing that co-locating 2 CS18.2 in the same location as my Trinity would give me a considerable increase in SPL and I expect the SQ to be improved over the Trinity (based on what I've read here in the forums).

Does the Dayton amp used with the 18.2 provide an LT circuit beyond the parametric EQ band? I thought I read that it did just trying to confirm.

Yes - There is a defeatable Bass Boost switch that acts as the LT circuit. Some users have found it isn't needed, others have found it helps. Of course, this is room dependent. Rooms with more room gain below 35 Hz tend not to require it.

Wow that was fast and right from the source!

My room is 24 x 17 x 10, and I have 2 18.2's stacked in a corner. There is headroom and spl's galore. My house really could not take much more.

I switched from 4 epik empire's, and 2 svs pb plus 2's. The 18.2's will not disappoint you.
post #529 of 689
I have (3) 18.2 with 2 co-located and the other in an another corner to help smooth the response. I can touch 130db in room with no compromise in sound quality. That is LOUD! I would get about 6db less with 2 units. Loud is great but to do it with clean and tight sound quality is the icing on the cake. IMO, you will not be looking for more with 2 units in your room. I am coming from (2) SVS PB12 Ultra/2. The first two 18.2 beat them in every way and by a significant margin and then I added the 3rd to help a difficult room.
post #530 of 689
Holy moly, that must be intense with 3 18.2's. I only have one with a MFW for fillin bass and it's just nuts. I turned off my buttkickers because the were redundant(they didnt shake my berks nearly as much as the 18.2 did)

Congrats on a sweet setup /envy
post #531 of 689
Scoobygt68 two 18.2's would be awesome in that room whether you co-locate them or not spl availability will not be a issue. I have one in a large open floor plan house and to say it can provide clean , undistorted spl is an understatement. And this is coming from a real bass head. The only reason I would ever want another would be to smoothen room response. You guys with two or more I also envy you!
post #532 of 689
You guys are killing me, I also have a Def Tech Trinity and only had it for roughly 4 months. I have to say that it is a great sub, but always looking for something with more punch. Just reading this thread this sounds like the sub of choice for the money.

Now my question is should I jump on the 18.2 or go with the Duo 18.1T? Hum... the craigsub is only 7" taller and 2" deeper and wider than the trinity. But are they all down firing for the single drivers?

Those of you that went from a Trinity to either Dual 18.1's or the single 18.2, I would like to hear your thoughts on the improvements. I have a 17'x25' room with 8' ceilings.

I have my AVR set at 50hz and running Large full range across the front. So the Sub is only pulling from the surrounds and "LFE" in moves.

Thanks for your input!

God, this hobby never seems to end! If it isn't speakers/sub it is electronics!

Why? You aren't letting that sub do its thing with that setting on the mains and with the 50 hz crossover. Mains should be msall with a 80 hz crossover,

That's how I set my speakers. I have towers on all my channels and I have them set to small crossed over at 80 hz.

I believe this is a picture of the Pro-10 speakers, is this what the finish on the CS18.2 series 2 will resemble?

post #538 of 689
I was wondering how the sub was measured? Is this CES 2010 peak output or something else? The new HSU sub has higher numbers with a single ported 15 which does not make sense.
