A few days ago I picked up a pair of old DIY speakers. The are about 5.5cubic feet and have 8 small holes (no tube, just holes) in the baffle board. They are about 1.5 inches in diameter. They result in some chuffing but add bass. I covered them with duct tape and the speakers sound a lot better. The speakers also had some tiny radioshack horn supertweeters (alas, not the decent ones made by Fostex). I disconnected those and instead sat some SEOS-12 horns with DNA-360 compression drivers on top. I'm using a miniDSP to attenuate them and implement a high-pass filter. The Altecs are still running full range. Things are sounding pretty darned decent now and I'm wondering if I can re-implement a better ported design in these boxes that won't chuff or if they are just going to sound best sealed. I'm thinking about getting serious with these cabinets -- new baffle boards, etc.. I also have some smaller ~4ft Barzilay-ish cabinets I could use. They are nicer but obviously smaller and aldo shorter so they wouldn't get the drivers up at a seated person's ear level and would have to be tipped back a bit I think. Thoughts?
