The slide in insert that shuts a doggy door ...........
Hey guys, I'm a newbie here, but am intrigued with these sound exciters! I have been playing around a bit with these and experimented with putting 2 exciters on the back of an acoustic guitar and the result was pretty awesome! I don't think it's audiophile grade by any means, but sounds a lot better than a lot of normal speakers. There is a natural sound and when there is acoustic guitar playing you almost think the guitar itself is playing! Here is a demo on youtube: https://youtu.be/GRJdIv_zvagLet me know what you think, and what could improve it!Thanks!
Hey Tom, welcome to AudioCircle. Interesting experiment! Maybe try damping the strings, see if that cleans it up a bit.
Groovy !!!!!!! ........... That really opens up a lot of other possibilitiesfor the exciters. (Cringe (Lest I say resonant))
Like the guitar! - think I saw one like it somewhere else too and there is also ones with pianos that can be bought. Almost a full orchestra now! Try losening the string so they are not super tight and perhaps dampen them with felt. You can perhaps use it with a capo so it looks nice. I wouldn't play to low bass on it with the fear it would ruin it or losen the glue over time. You can power the lepai with a battery so there will be no cables shown. That would be a sucess on a party to be able to fake play some pretty advanced guitar solos!!!! Or even better, remove the case or get one of the small chip amps and hide it inside!
I think I will test some stuff that sign and such makers have.There seems to be multiple types of Kapa board available. Ther had been mention that kapa is no good but any idea on the material? There is everything from paper to aluminum skins. Also anyone active listened to dibond? How they would compare to foam?This will take some scouting. -Ossi
Hi osssyvan,I went to one of my local digital print stores and introduced them to the world of sound exciters, they thought they were pretty cool! Anyway, I did have a chance to test a few materials while I was there. I tried foam board, Gatorboard (black) and a large piece of dibond, it seemed to be aluminum sandwich with a plastic core. From what I remember, the dibond sounded decent, but I believe the gator and foam board sounded better, I think the dibond was too heavy. I was using a dayton audio exciter, the one with the three legs, powered with dayton dta-1 battery powered mini t amp. It may be worth you checking it out for yourself though! Cheers!
Now, I do have to admit, I do not know how to play the guitar for real yet, my wife had bought me this guitar a while ago and I took a few lessons, but never continued to practice. Right not this is the closest I get to "playing" the guitar
OB_ newbieHow did you get on with stripping your exciters?Way back on page 10 their are some pic of what to expect when they have been stripped.Gatorboard was the panel zygadr used many years ago ,but in the end I believe he felt it was over damped by the two layers of coating,although it performed well.He then moved on to vh eps ,very large panels again,he was very lucky with his supplier , I would of had to buy in bulk at great expense , I only managed to get a small sample,I wish I could have tried this one in the larger size ,lightness and rigidity ,no damping.Steve
What have other folks tried for treatments on ply?
Time to go exciter shopping again. I need to get a whole bunch of exciters for some panels that is not going to play so loud so I'm wondering which of the lower priced one to get. So far I have pretty much focused on the 40W ones, but need some new ones to experiment with on tiny panels.How are the Dayton Audio DAEX25FHE-4? or any other good low cost options?On a different topic: These smaller bass shakers have caught my attention as a potential for sub panel - TT25-16 PUCK. Anyone tried one?BTW: The newer one Dayton DAEX32Q ones are on sale, but are they any good? OB - did you get yours to sound good once 'broken-in'?
- Have tried PVA glue-mix per the XPS/EPS receipe. Didn't do much if I remember it correctly (no significant change on measured frequency response or noticable difference in sound).- Properly gluing the exciter made a big improvementon my panels.Have you tried larger panels and cross lower to get some more dynamics?
Sedge - Excited to see more on the ply panels! Still my favourite! I even had a bass ply panel behind my couch for a while to even out the room modes (only took it away since I needed the exciter for a new experiment)Ossyvan and Sweenz27-Re - Gatorboard. In the US, it's easy to get hold of either gatorplast or gatorfoam and I have tried both but only in small sample sizes. I liked the foam version better, and I got better result with this than the XPS. But again, not sure how it will sound full panel. A bit too pricy in large sizes. The aluminum/brushed cupper looking sign boards are interesting. I tried a small sized sample. They take a hit on db vs wood, but - they take the frequency way way up - perhaps past my measurement range. In fact, I had to put a Low pass on it around 20Hz since it "tickled" in the ears - couldn't really hear the signal other than it felt somewhat uncomfortable. So very promising as a small tweeter panel.Time to go exciter shopping again.
