MTMWW - taoiseach

So wife let me spend some money with Cinergy yesterday - to the tune of four 8” Motus and four 5” Motus. I also bought another pair of Chinese beryllium tweeters, so will be building a close to end game MTMWW using these drivers.

Based on advertised specs I should reasonably expect mid-30s extension in 2.5 cubes.

Other builds are currently going to be back-burnered as I start the serious planning on this one. I sill want to finish my W/TM 3-way and possibly do the GRS based 4” 2-way as well but this one will take priority come spring/summer.

Anyways, my wife rules.

Wow. Should be something.

I like this with the Motus. Back when Motus was unobtainium, I had secured a pair of the 6.5”. Had allocated a Rival 9” to go on the bottom end. Would 2 8” do well with it? Do i need to add 8 more woofers to my stack? Would this ever get built?

Interested in your thoughts, tests and design parameters on the 8" inchers and the entire build!

Hope I get the opportunity to hear this. Those Motus drivers sure are enticing

Definitely sexy looking drivers! Those would have to be OB if I bit on a set.

Let your sexy motors hang out. I agree. Maybe mount the bottom woofer backwards and open back the mid.

I will say this, the suspensions on the 5” do allow to be overdriven. Not sure if this means OB is a bad idea or not.

As sexy as they are, open back isn’t going to happen. Not a huge fan of how they sound.


Can’t wait to get home and open these up!

I have to say, outstanding shipping service considering weather in Ohio recently. Erich is on top of things.

Pictures pictures pictures!!!

3” full range I added on a whim. Pretty nice for $27 IMHO.

Everything was packed very well using lots of acoustic foam.

Those are some good looking drivers.

Fuck yeah​:smiling_face_with_sunglasses:

Darn! I wanted to find golem saying “precious “, but I’m coming up dry

VERY groovy woofers !

I am thinking of doing this modular - with the MTM and woofers in separate enclosures. This will help facilitate moving them. Otherwise I imagine these would end up well over 100# per side.

This is all four of the 5”. I did not measure Vas. Little disappointed in consistency, to be honest. I am running them as dedicated mids so no worries on the bottom end, but for all intents and purposes I have two matched pair that are a little different from each other. Pretty much within 10% which I have been told is all I can expect.

Actually not bad over their expected range.

You may just need to slightly tweak left and right crossover components, but I’m thinking not when establishing your two pairs.

Edit: I generally get some variance by just running DATS more than once…
