Baby Boomer Sub

Sun Jun 01, 2014 6:15 pm

I just completer a pair of Sopranos... they sound wonderful, but they could use a sub. I'm considering the Baby Boomer, but have not seen anything on it. Has anyone out there built it, and I'd be interested in hearing about impressions.

It was designed specifically to go with those by Jeff. That should be enough endorsement.

Thanks... I know that's true, and I,m reasonably confident it would make me happy, but I'm hoping to hear from some folks who have actual experience with one.

Well, I have some experience with it, what would you like to know? Maybe I can answer your questions.

It was designed to be a small, low cost subwoofer, that still had some decent overall performance. Despite its size with will reach 28 Hz and play fairly loud. I made it for my brother who has the original Sopranos as well.

He uses the vented version, which is what Meniscus sells. I also designed it to work with dual 10" passive radiators. This version has no port noise and a little higher output on the bottom end.

It is matched with the Yung 300 Watt amp with boost. The woofer is a very nice driver for the money with a great set of parameters for a small box.

Thanks for the reply, Jeff. I've never had a sub before and really know little about them. I'm not into home theater, just stereo, and my listening taste include mainly instrumental classical music... orchestral, chamber, and piano. I guess I'm a little insecure about whether a sub, and particularly this sub would enhance my listening experience. If I think it through, the only way I'll find out is to dive in. Since volume is not the issue, but lisening experience is, would the passive radiator version have value for me?

The Baby Boomer was my take on a very small subwoofer. If you do not need a tiny sub then there are a lot of options. For the kind of music you enjoy you might prefer a sealed sub. An SDX-10 in a 1.5 to 2 cu ft sealed box with a nice plate amp would be an excellent sub for your genre of music.

Thanks, I think I'm gonna take your advice. I'm curious, though... I looked up the SDX-10 and see in the notes on the spec sheet that they suggest a sealed 24 liter box (just under 1 cubic foot) stuffed with 16 oz of polyfill. What effect will the larger size you suggested have on the sound?

The slightly larger box give a little lower Qtc, which has better transient response and matches up very nicely with a room.
