Tca 18.2 - Page 18

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.

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.

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?

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.

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.

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).
