I still need to get an active crossover too. Will be soon. So I ordered two types of the zxpc horns, the 18x10 and the 17x11. Tried them both with the B&C 75 and found I like the mid of the 17x11 but the highs of the 18x10. Is there another Horn I should be trying as well beside the 402? It's out of my price range right now, I have too many other things going on. I figure spending the money on a good active crossover would be money well spent.

Here's the inside of one of my k-400s. Quote Link to comment Share on other sites More sharing options...

The last K510 I saw looked quite strong. Of course, a tractrix horn is a lot shallower so you won't have a heavy driver on a long, skinny throat.

risingjay Posted February 2, 2020 Author Share Posted February 2, 2020 Well, gonna try and get these in my house today and have a listen....or two. Question for you smart people out there, If I were to get an active crossover, would it be easier to tune the horn that has a good mid with a slightly less top end or easier to tune the horn that has a little less mid but good top end? My room has a full acoustical panel ceiling, padded carpeting with a few acoustical panels on the wall. Room is roughly 14'3" wide, 17'3" deep and 7'3" high.

You have the lamp from Christmas story.😀 I have seen a few people turn wine barrels into a subwoofers. Thanks, it took me about a year to complete the room. I custom on built the ceiling and walls. The room was supposed to have pallet wood on the walls but I couldn't find or didn't like the pallets I looked at. So I used new wood and distressed, beat, burned, gouged, stained and a bunch of other techiques to make it look old. The barrel is for my bathroom that is attached to this room. I'm turning it into the vanity with a copper sink mounted flush on top. My projects never end in this household, either by choice or being forced by other occupants, but that's what we for the people we love. Not sure how she deals with me! 1 Quote Link to comment Share on other sites More sharing options...
risingjay Posted February 2, 2020 Author Share Posted February 2, 2020 My ceiling sound panels are removable so I have access above them, can't do that with drywall, well you can but it will be messy! Quote Link to comment Share on other sites More sharing options...

risingjay Posted February 2, 2020 Author Share Posted February 2, 2020 I have plans on putting sound panels over them at a later date. Not sure if it will help though. Any other alternatives to the windows besides closing them up? Quote Link to comment Share on other sites More sharing options...
SWL Posted February 2, 2020 Share Posted February 2, 2020 Definitely consider some diffusion in addition to the absorption that you already have.Sent from my SM-G950U using Tapatalk Quote Link to comment Share on other sites More sharing options...
