another simplexx 12 tilt back question

#1 Post by Askia » Mon Aug 01, 2016 10:57 am

It looks like, the tilt back design is slightly smaller, than the normal simplexx 1x12. If I remember well, the depth is 0.5 inch shorter. And also, the 45 degree cut makes the box even smaller, so... Maybe they wouldn't sound the same? Smaller box, less low end?

The answer is written somewhere else, or the question is so dumb, it doesn't worth answering? :feedback:
Thanks!

The tilt back will have a bit less low end, but not by much.

Thanks for the answer Mr. Fitzmaurice!
Someone had the chance to build and try one?

Now, that I have the plans for a tilt back, I'll build a TiltBack airhead version.
My amps have 300watts output on 8 Ohms, and as I don't want to fry the speaker by accident, so I'm planning to put a 3012HO or a 3012LF and a BGH 25 tweeter.
As Bill said, the TiltBack has "not by much" less lows, maybe the 3012LF would equalize this loss on the lows. Another thing is, that most of the time I'd use the speaker in tilt back position, so in theory I'll have less low end emphasized by the floor, this way the more low end from the 3012LF will come handy.
Could you give some feedback on this idea please?

With only 300 watts the 3012LF won't have any better result than the 3012HO. The LF will go louder in the lows due to the higher xmax, but only if you have at least 400 watts powering it.

That theory is incorrect. Either you misinterpreted what you read somewhere or you read something from a source that should not be trusted.

This case I might simply use a 2512, and be careful not to fry it... or even a basslite, which has higher xmax, but I have to be more careful, due to its 150W power handling. In tilt back position I'll hear myself well, and I'm not playing in loud bands. :)

I'm only talking about the theory I might know wrong, that as you raise the speaker from the ground, you'll get less lows, and thought if I tilt the speaker, it will have the same effect. I'm happy if I know it wrong. :)

True, if you raise it at least 1/4 wavelength. At 100 Hz that's 2.8 feet, at 50Hz 5.6 feet. :shock:

Well, raising the cabinet that much would be personal monitoring on ear level :lol:
