18 Sound suggested designs

[scameron78]

there are 2 designs i have always been interested in. working with their concept of each, i've been trying to design my cabinets around the peavey low rider 18. the first concept is the 18 sound dual 15 kit. http://www.eighteensound.com/staticC...kit15_dual.pdf
now i would use the low rider and adjust the chamber for the 18 driver. also to help cut down size i've adopted the M&K look with one driver facing forward and the other firing up. only in design mode but i wanted to hear from any one that has experience with a push-pull cabinet.

the other is the 18 sound dual 18 bandpass. i like the look, but don't know how it would perform with the peaveys. looks like my LF chambers would have to be pretty big? i've been messing with bassbox pro. i heard an old set of EV MTL-4s and i liked the sound. i believe they are a manifold design? same concept as the 18 sound bandpass only with 4 drivers per unit and huge. i guess i am really thinking out loud here. i am looking for a different design besides the usual reflex. have 4 peavey low-riders that will be used for live band application. i'd like a horn design, but completely unsure what design these drivers would work in.

this is the concept i have for the push/pull design.

You could try the MTL-2 design that DJmarvelous just built in one of the other threads , he seems quite happy with them. Plus side they're half the weight of a MTL-4

looks interesting
though due to risk of diaphragm sagging, I would be cautious with horisontally mounting of such big heavy coned woofer
in short, I wouldn't take the risk

yeah, that thought has crossed my mind.

is he posting the plans? what drivers? i probably should do a search and see what i can find.

design i came up with today based off the 18 sound design using the peavey lowriders. ports 4x4x14. 11.5 cuft.

Have you modelled that box ? What's the mach velocity for the all the 4*4 ports on each sub? (Djk)? has boxes like those I think but he has one common slot port on the one side that serves both subs in each box.

i used bassbox pro to figure the cu ft. can't remember what i tuned the box to. the ports seem small to me. don't know if they would be noisy. this was just a quick design. i wanted to get the proportions figured out and over all size of the box. yeah i asked DJK for his concept behind his manifolds. i read a forum where he said you basically figure the cu ft and ports for the driver as if you are building a reflex.
