Author Topic: EV Tl-880 Vs 4645c JBL Oliver Pasch Film Handler Posts: 53 From: Europe Registered: Jun 2002 posted 03-16-2004 06:06 AM                    Cher Nicolas, if you're asking for the ultimate (but affordable / reasonable) subwoofer, i'd suggest to check out this one: http://www.krix.com/kx4610.htm We've bought some of them during the last years from Kinoton in Germany and believe me, you will never want to think of the tiny JBL-box again... 3 of them are installed in our large auditorium (500 seats) in Aarhus / Denmark, the stadium seating is a construction with a floor of wood, this installation kicks a**! Just one important thing: you'll need very solid amplification power to drive this one, as this one goes down below 4 Ohm in the concerned frequency range.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 03-16-2004 06:33 AM                     And yet...a properly installed set of JBL 4645C goes even lower in frequency and puts out more power. I've yet to not have the 4645C (or B) out perform most any other system. If you don't complete the design with a B-6 filter, you haven't heard what the JBL system can do.

I have recentely listen to subwoofer with 2245h. I was very disappointed result. that brews wind but it is all. I do not find any quality with this speaker. There is no pallet of sound. It is one will infra mono. On/off This speaker is used in the box of the jbl synthesis. I ever knew which speaker is used in the sub synthesis. It look like 2242 but it dosen't sound 2242. + Nico  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 04-26-2004 05:00 PM                     The 2245H is an older driver. It has a lower frequency response than the 2242 or most other 18" drivers but at the price it can't handle as much power. As to the driver...it is all in the box that it is in. The original 4518 cabinet (no suffix) is the one that JBL issued the 2245 in. It was not the best enclosure as it was too small. I believe the 2245H performed its best in a 12 cu. ft. enclosure and the 4518 was an 8 cu. ft. For the home, it was the B460 subwoofer and it had a 9 cu.ft. enclosure. 2242H is a much more powerful driver but it will not go as low due to its suspension.

There were 4 box. But the result was not there. I could listen to very many times the system synthesis Jbl which use components professional (Vertex speaker). And I doesn't understand why that never goes as it is necessary ! I now that the 2245 is used in the Clairbros S4 during few years after 2241 ... I think that one does not have the same vision of the sound reproduction in France. For the moment I have very a big preference for the Kcs c218. And yet I am a fan of jbl I listened to not badly system Imax (sonicsound). The medium high is very good but the infra..... hummm I know that they used jbl and ev speaker but now I do not know what there is. I see that you often advise Jbl. Is what you work at Jbl ? + Nicolas  |  IP: Logged Antonio Marcheselli Phenomenal Film Handler Posts: 1260 From: Florence, Italy Registered: Mar 2000 posted 06-06-2004 05:58 PM                        I had chance to hear both model of KCS, 118 and 218. I can say that they cannot challenge with JBL or EV (at least the EV I've heard!). Martin Audio cinema subs are much better than KCS, and array of 6 Martin outperforms an array of 5 (dual driver) of KCS 218... Unfortunately the final results depends too much from equalization, acoustic and general setup. Bye A  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

I do not work for JBL but often recommend them when they are the best solution. As drivers go, JBL is definately one of the best. Their CD horns are also quite good. I also recommend Altec and I don't work for them either.

You prefer Tl880, therefore? I listen the 4645c but I think a lot, in bad condition. A friend has just ordered a 4645c. But he did not think of the B6 correction. The problem it is that one does not have an spectrum analyzer. that will be hard to regulate. He did not receive it yet. I hold everyone with the current as soon as the first tests are carried out. Your favorite sub for this moment ? Hello Steve Gutag, my questions should not be taken badly . In French forum people do not stop saying good of a product. Because in made these people there sell this product of exclusiveness. Much one bought the product which with final is very bad. Thus I am wary much. but it is very pleasant of your share to answer me. And your answers are a mine of information. In this moment thus the 4645c is best the subwoofer any mark confused? Have a classification of your favorite subwoofers ? The best amplification for the 4645 is ? Thank you very very much.

They have a VERY limited frequency responce. Nicolas, what is the primary use of the subwoofer you're searching? Cinema, home theater or hi-fi? For an hi-fi enviroment a subwoofer with very low deep end perhaps is inappropriate. A very low frequency subwoofer can sound too invasive with hi-fi music. Since KCS are more limited in low deep end perhaps they seem to sound better. Remember that 4645C and TL880D are listed in CINEMA speakers. If you check others JBL subwoofers they usually do not have the cinema's subs low end. Let us know what you found with your 4645C. Perhaps I'll have the chance to test a 4645C in my home theater room. Actually I have a 4688 and it sounds great, I will try a 4645C in B6 setup...

I think this is what I like them. They are very fast in times response with very large impacts and massive. I did not have to like at all the tl3512 Ev because of their moless of their slowness. I had as noted as the cases of the tl3512 was very light in construction. But in against part they go down without problem much low than the model c118 of Kcs. One needs that I order St-cx1s Radio Design Labs, for using the 4645c. well But I do not find a distributor in France. I must thus order it in Usa. But where?! I repeat it, the sub will have as well walked in hifi as in home cinema. + JALABERT Nicolas  |  IP: Logged Antonio Marcheselli Phenomenal Film Handler Posts: 1260 From: Florence, Italy Registered: Mar 2000 posted 06-07-2004 02:48 PM                        Nicolas In cinema's soundtrack the LFE channel is mainly intended for Very Low frequency effects. Each mixers has his own preferences of course but usually the SW channel is used mainly for explosions and effects like that and the other bass frequencies are left to stage channels (again: it depends to the mixer!). If you put a cinema subwoofer that go down to 20Hz in a hi-fi enviroment probably the low end will result too much present and not controlled. But hear this sub with "Star Wars" and you will hear the difference! On the pdf of Tl880D EV suggest to use B6 alignment (step-down) only for cinema application for example. Question: can be a good idea to have an equalizer with a double setting flat for Cinema application and cut on very low frequencies (35Hz?) for hi-fi applications? Just an idea.

On Star Wars this is not good. that brews air but it is just like the 2245h. There is no effect of massive like Kcs. I try do see the thiel & small parameter result of that bad sound. I am in a hurry to listen to the 4645c. I have broad a enough budget for the subwoofer. Bye Nicolas  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 06-07-2004 10:18 PM                     The TL-3512 shouldn't even be listed as a subwoofer. It is nothing more than an ordinary LF driver in an LF enclosure. It used the DL-18W woofer which was nothing more than and 18" version the DL-15W woofer as used in the TL-606 dual 15" base cabinet (used in the TS-940 and TS-9040 systems). Before the EVX-180 was mucked with, I'd say in that cabinet sixe you would be better served by the the TL440. As to the ST-CX1S...I know we have them in stock at the moment (dont forget the PS-24A power cube when getting one). If you use QSC amplifiers, they offer a "sub filter" module for most of their amplifier lines that also as a preset B-6 filter.

(mucked) I'm not very good in english. I don't find the traduction of the world muck. You sell the module ctx. Would have a bond of your site of sale? Send you for France ? For you the BEST subwoofer for use also in hifi mode or home cinema is the 4645c ?
