  1. The room is 3900 ft3. If I decide to go with the Klipsch THX Ultra2 I will probably order 2 THX amps and 2 THX subs and then use the Sub 1 and Sub 2 preout connectors on my Marantz AV7702mkII. Audyssey should calibrate the subs separately when they are connected to Sub 1 and Sub 2.
  2. I spent some time reading through the Seaton forum and did not see any reference to an in-house cabinet shop. This is the only cabinet maker they mention: http://www.seaton-sound-forum.com/post/behind-the-scenes-submersives-in-the-making-5489409 I assumed the cabinets were outsourced and Seaton installed the drivers and amps. There's no doubt they make a quality product.
  3. I've been doing some digging to find out more about the sub manufacturers and how they go about building their subs. The curved cabinets of the Funk subs look great but the prices are too high. It seems Funk Audio is a one (or two) man operation and their subs are built from the ground up with their own cabinets, drivers, and amps. However, for the money I'd feel more comfortable going with a more established brick-and-mortar or ID brand. I contacted Deep Sea Sound to inquire about the cabinet build and driver used in the Mariana 18S Sub. I wanted to find out if they were building the cabinets and drivers themselves. I got the following reply from David Gage: "The 18" subwoofer driver is the HST-18 D1 built by Stereo Integrity near Charlotte North Carolina. The SP1-4000 amp with 4,000 watts of continuous power is built in Santa Ana, California. We build the enclosures ourselves in Knoxville, TN and then put everything together and test thoroughly before shipping out." It appears DSS is using quality components from well-known manufacturers. DSS is a new company and I would lean toward Seaton, Klipsch, etc. I sent an email to SVS to find out where their subs are made and I got the following response from customer service: "SVS products are designed and engineered in the USA, and manufactured in Asia to SVS specifications, under direct SVS supervision. All SVS products shipped from our OH facility undergo a comprehensive QC and audio check by our factory technicians before being shipped to the customer." SVS subs might not be the best but their customer service is supposed to be quite good. The Seaton SubMersive cabinets are CNC'd by WW Speaker Cabinets and I was not able to find info on the drivers and amps. Does anyone know if the drivers and amps are made by Seaton or purchased elsewhere? I don't recall seeing a photo of the driver used in the SubMersive HP+ or F18+. JTR uses Baltic Birch construction in their Captivator S1 and again I was not able to find info on the origins of the drivers and amps. I've cut the sub choices down to the THX Ultra2 Subs, SubMersive HP+, SubMersive F18+, JTR Captivator S1, and SVS SB13-Ultra. On a side note, it's always interesting to read about comparisons between these subs and the JL Audio Fathom, Velodyne DD+, and top-of-the-line Paradigm subs.
  4. I agree that it’s generally not a good idea to put a cabinet inside a cabinet. I probably won’t get optimal performance from the sub and there will be issues with airflow around the amp, etc. I think the THX Ultra2 subs might be better suited for in-cabinet installation than the other subs due to the front firing woofer, front port and external amp. Ehhhh... not really comparing apples to apples. Too many variables. Some of the ones you mentioned do have nicer amps. Plus, well, 18's and stuff. But, they're sealed, and really need multiple units for great response down low, which gets expensive real quick. On a mild build you may be better off with the THX especially if it lets you afford more subs. The THX would definitely would be real easy and would visually match nicely. Biggest issue with integration in my opinion is that the THX mains have to lean on the subs for midbass quite a bit, so you're not going to want to get something that only sounds great down pretty low but doesn't extend up high very well. I have four Seaton F18 clones and three KL-650-THX's, come over and we'll see what they can do. It's the same amp, same DSP, programmed by the same guy, same subs, about same size box, and same stuffing. I’m in Canada and most of the quality subs are made by American companies so I will end up paying more for USA made product due to the weaker Canadian dollar. I can afford to buy a pair of SVS SB13-Ultra subs or a pair of Klipsch THX Ultra2 subs and matching THX amp right away and with the other subs I would have to buy one sub now and then add the second sub (if necessary) later in the year. I don’t mind spending more money on another brand if the increase in performance over the Klipsch or SVS justifies it. Performance down low and extension up high is of concern so any sub I look at must meet or exceed THX spec. I believe the Paradigm 1000SW will be out in this regard. A false wall is in the plans and I will be ripping the cabinetry out when finances permit construction of a dedicated theater. I just bought the house a year ago and the cabinetry was the previous owner’s idea. I hate it but I have to live with it for the time being.
  5. Hi, I'm a new member to the Klipsch family and I have some sub questions. I purchased the THX Ultra2 system without the subs a few weeks ago and now I am ready to add one or two subs to the system. The Ultra2 speakers sound amazing but the old Velodyne CT-120 sub I am using just isn’t up to the task. One or both subs will be placed in cabinetry with openings that are 23.75" H x 22.75" W x 22.75" D unless I can place the subs in the room without giving up too much floor space. The media room is 18' x 24' x 9.' I haven’t listened to the Klipsch THX Ultra2 Subs and I was wondering if they are still considered to be great subs? Has the THX Ultra2 Subs’ performance been surpassed by newer subs introduced by other companies? Do the THX Ultra2 Subs integrate with the rest of the Ultra2 system better than subs made by other manufacturers? The following subs are being considered along with the Klipsch THX Ultra2 Subs: SVS SB13-Ultra Funk Audio 18.0C JTR Captivator S1 Paradigm Prestige 1000SW Seaton Sound SubMersive HP+ Seaton Sound SubMersive F18+ The Seaton subs are too big to fit in the cabinetry but they are an interesting option. I will be able to listen to the Paradigm 1000SW at a local dealer but not the other subs.
