wsu99999 Posted January 21, 2009 Share Posted January 21, 2009 Hey Subwoofer Junkies - - I have an URGENT question for you. I have a guy that is willing to sell a KP-480 to me for 290 bucks. All I know is several years ago this sub retailed for around a grand. I know it's used for professional setups, but I need to know how it will work in a home theater/home stereo application. Clearly, I will need an additional amplifier, but I need to know if anyone out there has used this sub for home use. Also, is the price I'm getting it for good? It sounds like a great deal - 18" active woofer and 15" passive for under 300 bucks! Let me know ASAP because I would need to buy it today or I will miss out.

Guest " " Posted January 21, 2009 Share Posted January 21, 2009 The 480 was designed to be used with the LaScala. But, notice it only goes down to 44hz. It's more of a PA woofer, not really an LFE home theater woofer. Quote Link to comment Share on other sites More sharing options...
wsu99999 Posted January 21, 2009 Author Share Posted January 21, 2009 Considering I would be running it with 2 LaScala's, do you think it would be a good buy or should I put that money elsewhere? Thoughts? Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted January 21, 2009 Share Posted January 21, 2009 If it's going to be used for HT also, I'd put my money elsewhere. DISCLAIMER, I've never heard those subs, but from the specs, they don't look like they'll dig low enough for HT. Quote Link to comment Share on other sites More sharing options...
Guest " " Posted January 21, 2009 Share Posted January 21, 2009 The kp-480 is designed to be connected in line with a lascala. There are input connections from the amp and output connections to the LaScala. Ideally you would need a pair. These are not really sub woofers in the HT sense. For the kind of money you are talking about, you can buy a powered sub woofer with dual passive inputs or line level inputs. My JBL120 subwoofer cost me 300 bucks and has a built in 400 watt amp.

wsu99999 Posted January 21, 2009 Author Share Posted January 21, 2009 Thanks for the information - you probably saved me 300 bucks. I just thought 18" sub with 15" passive, how could you go wrong. Quote Link to comment Share on other sites More sharing options...
m54 Posted January 22, 2009 Share Posted January 22, 2009 keep in mind it's half space measured specs listed above. Typical home envirnment is 1/4 or 1/8 space which equates to room gain on the lowest frequencies. with that high sensitivity you could EQ it to a degree and get useful bass extension at 30Hz. I own two for PA purposes, and as I have DJ'd with them in large ballrooms and put the power to them, they are visceral and very good sounding/ low distortion tuneful bass/ not the typical droning of most PA subs. I limit the power at 20 Hz as they do come 'unglued' 'down there'... where some new heavy dance music resides... the passive radiators unload and have a flapping sound. if anything it is an audible governor and I back them down a bit, all the while the 18" drivers are protected. But that is when I am dumping 2500 watts peak into them. I would *never* play them that loud at home... on the other hand you may ultimately spend more $ to tune them appropriately for home use, and defeat the great deal. 1 Quote Link to comment Share on other sites More sharing options...
