Re: Sealed test enclosure

That's cool.
I will have to admit; the 54mm Xmax is really cool. Is the p2p Xmax around 3 inches also?

Re: Sealed test enclosure

Mercy! If BW limited down low in a BP4 to maximize cab efficiency, in a sim using the same net Vb as a max flat sealed alignment it outputs ~ as much as a Servo-Drive Contrabass for < the cost of a clapped out used one (~$1 k on average), though at a considerable expense in increased cab size (~27.4 ft^3 + vent Vp Vs ~10 ft^3)! If true, then from sad experience I know this thing is literally a potential house wrecker.

Re: Sealed test enclosure

Yes. They are house wreckers. My single ported one does scary things all on it's own. All 4 of the sealed ones together should be relaxed with anything I throw at them.

Re: Sealed test enclosure

I figured that I would post a few pictures of the first 2 cabs in their temporary abode that they will be staying at while I attempt to get the room at home and the other 2 cabinets completed. I forgot to take any pics of them all finished until I had already dragged them up to the rehearsal space and put them in place! I'm not the brightest sometimes. Anyhoo...

Re: Sealed test enclosure

Hey Josh,

Those dudes look right at home. The cabs look really good. Very beefy. The cabs must be way more solid than the one you had a few months back. The baffle is very thick, di you double up on the sides and back?

Looking good.

Robert

Re: Sealed test enclosure

Hey Rob. I left the sides, bottom and top a single thickness still, The baffle and back are thicker. Even still these are a lot more thoroughly braced and heavier than the one I had at the GTG. I haven't put the hammer down on them yet, to see whether I can get them to walk across the room.

If you bounce them in the spot they are in, it is going to be like a set of maracas.

Re: Sealed test enclosure

I've been playing with these the last couple of days. No bouncing on these cabs yet Robert. The extra weight and bracing seemed to help out a lot. I ran Bass I Love You through them at literal pants flapping level a couple of times and also ran Jurassic Lunch and Bass Mekanik's Toccata and Fugue a couple of times as well. I also used a bunch of pink noise, music and straight up mic'd kick drum. I'm trying to break these drivers in. This pair has been sitting in their shipping containers vertically for over a year and who knows how long before that, so the suspension needs a good stretching to knock the dust off and re-center it. I nearly tripped the breaker on Bass I Love You. The lights dimmed horribly. You can only get so much out of a 120v 30A line. I need to run third leg for this room.

Re: Sealed test enclosure

I'm envious that you have a room/house/whatever that can handle the pressure!

BTW, tried any of these uncompressed recordings? Don't have a clue how they compare to the bass centric ones since I trashed my place too quick with pipe organ symphonies and a couple of movies before I could try any of them.

Re: Sealed test enclosure

I sure have enjoyed those recordings GM. Just not on these in this room yet. The Finale is one of my favorites. I also like the train recordings. The fact that you can hear so much of the natural surroundings (cicada's, bugs flying around, squeeks, air releasing) is really cool.
