Laying out speaker cabinet -- Two possible tracks -- 4- 12s or 2 - 12's --- probably 2-12 but my grandson thinks I should make two cabinets with 2 12"s with piezo tweeters. Which is better round or horn? And how many per cabinet. Do they change the impedance rating? I have read somewhere that Kustom amps do not like these and they can cause major problems. Are they wired with a pair or with each speaker. What effect to they really have because I have also read that they really make no noticeable difference.
I am building my cabinet out of solid walnut wood, with a natural finish not plywood as I have over 300 board feet available. I understand that can also change the sound over plywood. However, I like the look of real wood. It will be closed back and ported. There is very little chance this cabinet(s) will be used outside.
Also do I put insulation on the inside or not, again I have read "absolute" recommendations both ways. What is your experience? Thanks for your help.

Pleat - I am building it mostly for guitar but will also be using it for vocals. Will be using a six string electric, a 12 string acoustic electric and of course the vocals. Trying to find the best combination of sound. This will not be used for lead very much. If I use them I will get the 50 ohm 5 watt resister. You mentioned "You will get a much more pleasing sound without them" --- in what way? Mellow -- harsh --- tinny ? I am in an area here that I do not know well.

Piezos can be very harsh. Above 6000 Hz or so, most of your sound information is mostly harmonics and very small instruments like a triangle or piccolo. I realize that might sound strange by physics doesn't lie. You need larger and bigger to produce and reproduce low frequency sound. I might alter that if I were trying to amplify a female voice. I would prefer a 2x6 horn with a diaphragm driver but for the most part, in small venues, like the living room, 12" speakers work great. I routinely use 4 Kustom 2x12 cabinets in open air parks as a small PA. I use them for sound while showing movies. Not music completely but the highs are well represented. I have 3 cabinets with Jensens and and 1 with CTS's. It is usually the lows that get lost.

Thanks for the information - it helps. While it probably will not be used outside, it will be in different settings, from the living room to (in some cases) very large rooms. (churches) Thanks for the help, I am a real novice here having built only one speaker cabinet before.
