Deltalite 2510 in small box.

#21
Had the same issue with an older Carvin redline 410. When you tried to add bass to it at volume in would sound constricted or "choked off". Had a shelf port like that that ran the width of the cab and was maybe an inch (2.5cm) high. It's just a bad shape for a port, at least when using drivers that can move some air. Some box/port modeling programs won't even accept a shelf port if the width to height ratio is greater than 8 to 1. It's too narrow and there's too much constriction, friction, and turbulence from the air getting caught up along the top and bottom panels.

If you're willing to start from scratch, you could end up with a premium 210 with those drivers...better than a lot of stuff you can get "off the shelf". They have enough dispersion and upper response you can go straight to tweeter with no mid for fullrange, although, they have plenty of uppermid to make a nice bass tone on their own. Simple jack--->wire---->10's in a good box.

Most "typical bass cabs" are around 1 cu.ft. per 10" driver. Enough to give something down in the 60's. If you're going to run it with a sub all the time, smaller box/higher power handling is the ticket.

2 Deltalites + a good tweeter/crossover = way good PA cab.

Same thing will make a good bass cab on its own.

Like I allready said in post #15, the port's height of 1" is to small. If you build a new cab it's best to use a flared (tube)port. Even a 3" flared tube port won't chuff and whistle with most 10" drivers, I know cuz I tried it.

Flared tube ports are better IMO, less friction thus less noise.

Eminence speaker plans say to use a hpf for everything. I've never used one for anything to do with a bass rig and never had a problem or needed one.

I think it's just for insurance or warranty purposes or something.

I can see the need for the midbass tuned ones, looking at the graphs the excursion goes nuts at 40hz. EUB puts out a bit of that and the mb200 is simple EQ, the bathwater could get thrown out.

I built Eminence's medium vented 110 and it's a pretty cool little cab -- not the loudest thing in the world but it has fantastic tone. Wouldn't recommend it for anything beyond personal practice, a coffee house gig or something similar but it's a pretty fun and easy build and you'll end up with a quality cab. Also, I haven't installed a hpf and it's been fine.

There are 2 Eminence medium tunings for the Deltalite 2510, .8cuft 50hz and .6cuft 75hz, which is yours?

Jazz rehearsals are pretty low volume, I still use earplugs or I get ringing, Trace idles about 1 though the SWR. It is stupid loud for 250w though.

My main concern is not blowing a lonely 2510 with EUB. I might need to upgrade the MB200 for something with an effect loop so I can use my mini crossover to hpf. Trying to avoid plugging in extra stuff though.
