Mini Subs
« on: June 20, 2008, 01:10:25 pm »

I'm looking for some mini subs to use when LAB subs aren't practical. I'm considering Growlers, TH-Minis, and anything else. Whatever I get doesn't have to go insanely loud, but I would like it to get to 40Hz or so. Coupling of multiples is a plus like with the horn subs mentioned. Front loaded is fine too.

I built a small double LAB12 ported box and it sounds more like a car sub...not nearly loud enough but plenty low.

I haven't heard these Acoupower subs, but the specs on the website are impressive. This is a small company that designs and makes the drivers, and they do seem very well designed. They can also design, build, and test the cabinet for you. Some of their cabinets are really small, although they are not light, the driver alone weighs about 44 lb.

THe big difference between that cabinet and the other mentioned by the OP is that the sensitivity is 10dB lower.  That is HUGE and really hard to makeup.

It may be fine for Home Theatre, but not for live use.

Yeah, I already confirmed that LAB12 woofers front loaded aren't loud enough.

I think Ivan was saying the Acoupower box was lower in sensitivity than the dual LAB12 driver box, having a sensitivity of 90 dB SPL for 1 watt at 1 meter in a half space measurement. That is for the 15 inch driver in a 2.6 cu ft sealed box. Good point.

Acoupower does have a graph for a 100-103 dB SPL @ 1 m half space box on their website, but it is a dual 18" driver large box that probably weighs close to 200 lb, not what the OP is looking for.

We just did a quick demo with the TH Mini last Thursday for our small band PA. Use is for small venue live band blues/rock music. Most all of our larger gigs have PA provided. We have been using 2 Tuba 24's which were fine for the amount invested, but we have grown tired of the uneven frequency response they produce without a larger block of cabinets.

We have rented SRX subs in the past when concerned about the Tuba's not being enough for the gig and they were fine, but for replacement subs one of our main criteria is small size. My goal is to eventually get everything into our 5x10 trailer. (Not quite there yet, but getting closer.) I pretty much narrowed our choice down to the TH Mini as long as they sounded as good as the specs promised. While we only used recorded music for the demo, the band voted to buy them after about 3 minutes. They are increadibly small and put out an amazing level. True they don't go quite as low as the growler or other smallish 18" subs, but the sound is very powerful and has a musical/monitor quality to it and it is three cubic feet smaller than the Growler. If small is a large consideration for you, I can't imagine not being happy with the TH Mini.

I'm ordering two today and will update after some gigs.

Don't know if this is a post violation and it may get pulled off but we introduced the CS30 at the Infocomm show that has a sensitivity of 95dB @ 33Hz.  The data is up on the website in our brochure which you can download but it impressed all that heard it.  It won't get as loud as the Mini at 50 Hz but it will get much louder than the Mini at 33-40 Hz.

I didn't see the graphs and detailed specs for the CS30 or the SH-Mini on the Danley website. Did I miss something?

TH-mini     http://www.danleysoundlabs.com/pdf/TH%20MINI%20Spec%20Sheet. PDF

The CS30 was up there, but there is some "construction" going on on the website.

Here is a screen capture for 2.83V 1M  (actually 28.3V/10M)

Thanks, Ivan. Looks like the CS30 might work well with a pair of SH100s, which roll off below 70 Hz. That could make a really tiny PA with a full range response down reasonably flat down to 33 Hz. And it would fit in my car!

Any FR graphs available for the SH-Mini? I still get a "page not found" message when I look for it.

Thinking about an even smaller super-tiny nano-PA (NYC bars that fit 40 people SRO), it looks like the TH-Mini might be a bit much for 2 SH-Minis, and the CS30 rolls off way below the stated 125 Hz LF rolloff for the SH-mini. Have you tried the SH-mini as an FOH PA, if so, what would you recommend for a sub for the SH-Mini?
