McMiRA Posted January 10, 2014 Share Posted January 10, 2014 I have the opportunity to pick up a pair of kpt 484s and possibly a Yamaha p5000s amp. I am wondering how they will mesh with my LSI's equipped with k43 woofers ct125s and the c4500 crossovers and eventually port mod. Will I be gaining any bottom end or just more punch? Was going to use them as 2 ch for now and eventually migrate them into a heritage theater. Quote Link to comment Share on other sites More sharing options...
jason str Posted January 10, 2014 Share Posted January 10, 2014 Horn sub will blend much better with your mains. Quote Link to comment Share on other sites More sharing options...
McMiRA Posted January 10, 2014 Author Share Posted January 10, 2014 I originally planned on doing a pair of THT's but the price is right on these and kind of hard to pass up. Was looking at their specs and their sensitivity and output is right up there with the la scalas. La Scala 104db@1w/1m. 121db max 53hz-17khz Kpt-484 102db@1w/1m. 125db max 40hz-1khz(+-)4db (-10db @ 29hz) Just don't know what to expect from them. I'm one la Scala away from a 5.1 setup and once I acquire it I will roll everything into the theater but for now was going to use them for music. Are these worth a try? Would they compliment a pair of THT's once set in my home theater or would they not fill a void in frequency or punch? Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted January 10, 2014 Share Posted January 10, 2014 You don't want to mix direct radiator subs with horn loaded subs. Quote Link to comment Share on other sites More sharing options...

McMiRA Posted January 11, 2014 Author Share Posted January 11, 2014 I keep hearing don't mix direct with horns, now here's my question. Why? I'm curious as to what happens to the sound? Quote Link to comment Share on other sites More sharing options...
billybob Posted January 11, 2014 Share Posted January 11, 2014 Thinking that it has to do with time delays, reflections and echo effect. FWIW, sounds like a good way to experiment to see what the effect is for your self since the price may be right. Other's will give a more defining answer.

The sound out of a direct radiator hits your ears faster than a horn sub does due to the fact that the sound has to travel the length of the horn before it exits. The difference in time puts one slightly out of phase with the other and smears the bass. Quote Link to comment Share on other sites More sharing options...
McMiRA Posted January 11, 2014 Author Share Posted January 11, 2014 Is this something that could be worked out with phase controls or even audyessy? Quote Link to comment Share on other sites More sharing options...

Never heard of anybody getting it to sound correct. Maybe you could get away with it using a steep slope crossover but i think it would be more trouble than its worth. You can mix two similar horns like the Table Tuba & the THT if you feel the need to mix up some subwoofers. Quote Link to comment Share on other sites More sharing options...

Was wondering about that earlier. Would the non-directivity of a sub be overcome by facing the sub in reverse position toward the wall, thence echoing the physical position of the folded horn? Thanks! Quote Link to comment Share on other sites More sharing options...

jason str Posted January 11, 2014 Share Posted January 11, 2014 Either way will work, ceiling or floor. My thoughts with the crossover was if the 2 subs weren't producing the same notes they would not be stepping on each others toes. I still find having a sub somewhat centered between the soundstage sounds best. Quote Link to comment Share on other sites More sharing options...
