I have read somewhere that when several speakers are placed in close proximity with each other, as in the case of an Ampeg 8X10, the usable lowest frequencies go down by 10 or 20 Hz for every two speakers. If this is true, a 8X10 with midrange speakers usually best at 70 to 90 HZ, will, in combination, be best at 30Hz or less. Anyone know anything about this?
If true also, a good midrange 12” in a 4X12, even at 50Fs, should sound great and give you plenty of lows.
I would recommend a Altec or JBL industrial (theater) woofer. I have a…I think…a 3126 Altec, a wonderful speaker. Wish I had another to make a smallish 2X12. They are not too expensive, around $60 to $90 many times. Dang....guess I'll have to buy it and build it. That means some kind of Sunn grill cloth too...oh noooo...I have found a website that is filled with people like me....and they have all this cool stuff! I want more.
