New cabs for sad M 7s

Rev. Hayes

I have a pair of Monitor 7s (series II) that the previous owner had in storage for a long time. The base of one of the speakers obviously got wet at some point and the particle board swelled and split the miters. It's still holding the air just fine but looks too bad to put in the house. I love the sound and I hate to relegate them to the unfriendly environment I call my workshop.

I was thinking about making new cabs but not with the same boxy shape. I want to do a cab with a radius on the front sides and a plumb face but with an integrated "time align" tilt hidden by the grill.

If I kept the original cab design inside and "sleeved" it with the details I want would this change the resonance of the whole thing? I mean I sure it would to some extent but would it totally change the sound to the point that the xover/drivers and so on would be inappropriate?

Can you post a picture?

I wouldn't try to sleeve an entire cabinet, that is are you trying to do a box within a box?

I'm having trouble uploading my mental picture but yeah, a box within a box is basically it.

Just match the internal volume and you should be fine

What he said ^^^^^^^^^^

Rev. Hayes

Volume. gotcha.

That's what I was thinking I was just a little concerned about density, mass and so on.

I know cabinet resonance comes into play in how a speaker sounds but I wasn't sure just how much that is taken into account during the design phase.

This will almost certainly be a spring project so I've got plenty of time to come up with some bad ideas to run by y'all.

Right now the new caps for the Dynaco A 35s' just showed up so I have something to do over the weekend.... wait, that's xmas. Well, next weekend.... wait, that's new year hangover recovery.

New year's resolution #1- I will finish something

I tried my hand at this with Monitor 10's once. I built a double walled and braced cabinet with the mids sunk into the cab. They had a decidedly tighter sound, with more punch to the low end. Probably more I was not hearing the resonance of the cabinet anymore.

I don't have them anymore and would have to search the pit we call a basement to see if there are pics anywhere. I made these back in 92 or 93.
