NEED ADVICE , How To Get Good Bass in a speaker with Altec 416's ? or ?

-- Hello , I am looking for advice on how to get good bass in a horn speaker - I was going to go the Bass Horn route but my wife has asked if it could be smaller, So then I was looking at Valencia type designs and I'm wondering if I used Two 12 or 15 inch woofers per side, would that do what I want , which two woofers you would use -- if you were to use two woofers per side -- (they would have a Horn midrange and Horn tweeter top)

-- one 12 inch & Add a 18 inch driver?
-- two of the same pair?
-- two different woofers per side for a richer tone ?
-- Is anyone familiar with EVM12L Drivers? .... (they are supposed to have real punch and not crazy expensive )

what do you think - ?

OR is there some other woofers that you like for the price, it would be nice to find woofers that will do this that don't cost an arm and a leg - LOL

So I thought I would try and explain a little better what I am looking for, I want good Musical Bass.... and I want the kind of bass that has impact -- the kind that - it kind of hits hard enough you feel it in you gut - if you know what I mean - I'm assuming that it's the 80Hz to 200 or 300Hz range that has that kind of impact... but not sure. The next thing is I realize you can go buy some expensive JBL drivers that will do that , but I would like to do this as cheaply as possible.... thanks for any advice.

the old Karlson "K15" developed in the summer of 1951 and marketed from fall 1952 to Karlson's death Jan. 1973 can do that feat

Here's a setup which looks very nice

Most 15" with qts 0.4 to 0.25 will work well enough. A coaxial speaker as originally intended is good but some horn will work ok on top as can a "K-tube" with compression driver.

Plan from January 1954 issue of Radio and Television News. Later K15 narrowed the port but I would start here and tune "by ear"

brace the back panel. The "wings" can use struts from their inside to the front shelf edge (about 3.5" span)
