Collin, there is one more tip for you how you might bult a very inexpensive but very good performing MF channel, thought it might be slightly time-consuming…
It is not well-know but some, primary Japanese companies like JVC, Yamaha, Hitachi, Denon and so on, sometime used in thier cheap, consumers products, something the we call boom-boxes the remarkably good MF drivers. I mean really-really boom-boxes, soothing that cost $100-$300. They were/are usually 4”-5”, with very low resonant frequency, low handling power, sloth/paper suspended, small ceramic driver, relatively high sensitivity and with small phase plug in place of dust cover. They used them as full-range and thy never were interestingly sounding driven by the boom-boxes electronics. However, if they high- and low-passed, properly driven and sit in open baffle (or even used as the open drivers) then some of them sound phenomenally good. This Japanese companies 9or whoever was their vendor) manufactured then by large number and it is possible to get them sometimes for very little money. I am very sorry that I did not get more of them and it would be fun to make array of them.
I was funny I picked one driver from garbage near my parking spot. Someone trashed a JVC boom-box, and presumably the toss it from the window and it was complexly dissected when it landed. That time I was experimented with my own horns prototyped and when I glance at the pile of the garbage with the JVC atop I thought why don’t I take this visible 4” driver and stick into my 4” horn. The driver did very badly in the horn but I was surprised that driven by ML2 as an open driver it performed very interesting. In a few years I meet a guy who was going out of fixing consumer electronic business who sold me a large box with speakers for $10. All of then were the pulls from different boom-boxes and some of them were more then useable. I did inquire about to get the pair for them and the supply shops were wiling to sell me the replacements for around $20-$30 per driver. So, they are available… and sometimes if worth to buy the entire boom-box on ebay and then juts take the drives from there….
I know it sound too ridicules, but if you visit my room and if I supplement some of those boom-boxes pulls with complimentary LF section and if you listen it then you will not be laughing…
