hi,

looking for the best sub's which go down to only 35hz and that give out some very serious midbass kick for HIFI only. budget $2000 for single or multiple subs, room size 36ft x 30ft

any suggestions?

thanks

Look at Danley subs and the JTR Growler. Also think of folded horn subs or the THT can do some major damage because you can build 4 for $2000.

It is very unusual for someone to want subwoofers that only go down to 35 Hz. Even if you have truly full range mains (usually very expensive), you are almost always better off with a subwoofer for frequencies under 35 HZ.

Can you please explain how you are going to handle below 35 Hz please.

JBL, EAW, B52, Yamaha, Cerwin Vega, Behringer, Nady, EV, etc, 15" or 18" 'subwoofers'.

Visit Musician's Friend and take your pick from $300. They're all designed to take a long term pounding with program source to 30-35 Hz.

If you want one reasonable box to provide the most mid-bass kick, and you didn't define the mid-bass frequency involved, I'd unhesitatingly recommend this piece by EAW. It from the dance club series.

This is the DCS2 bent horn subwoofer.

(2) 12" drivers
36"x36"x36"
-3db @ 45hz
137db long term
143db peak

ooooontz, ooooontz, ooooontz, ooooontz, ooooontz, ooooontz





ooooontz, ooooontz, ooooontz, ooooontz, ooooontz, ooooontz







Good luck

One important detail I didn't see is what speakers are you mating to and how will you implement the crossover? Receiver? Preamp? on-board subwoofer crossover? Those flexibilities and what exactly you are looking for will help to narrow down your many options.

If you want to rattle your teeth with very good sound quality and don't mind adding your own amp and crossover, you might want to try the big brother to the growler, the Orbit Shifter Pro which goes a bit deeper. If ease of setup, size and aesthetics matter, you might want to steer more toward the home oriented offerings.

Mark is right, the JTR offerings would be great. They're essentially pro boxes, tweaked for HT.

Also, Bosso was correct as well. Generally pro subs have an -3db point around 35hz., give or take a little.

On the ultra cheap side, you can go Peavy. At less than $250 a piece, they offer a passive 18". (8) of these things and you've got a $2k sub rig you could power with an EP4000. (8) 8 ohm boxes, config'd 4ohm mono and powered by a mono Berry, would spread 250 watts easily across each coil. They are spec'd at 95db@1w@1m, so... 250w=119db@1m, .....and (8) boxes realizes a +18db advantage.... resulting in a 137db@1m, ....subtract 12db for a 4m LP=125db@LP@2kw.

Now all these are based on the factory spec of 95db. For a 35hz target, that spec may be reasonably close. When you add boundary gain and room gain down low, those figures would raise in level...potentially raise quite a bit. Boundary gain will get you back 6db per boundry,...all the way up to 18db fully corner loaded throughout the range. The driver needs to be within a quarter wavelength of the frequency involved to achieve full complementary loading. So at 100hz, the driver needs to be at least within 34" (1130/100/4) from the walls to achieve the full corner loading effect from 100hz. on down.

Any theoretical boundary gain one calculates must be lessened somewhat by the diaphragmatic losses of the structure. Which, I've got no good info on. So, this array aligned along the back wall perhaps, this would yield 12 db minus losses, which brings us back up to 137 db@ the LP before the boundary losses. Not bad. Also, spreading the power across so many coils, retains the snap and responsiveness of low compression. This would be a fun exercise, with a $250 18" sub.

Also, the box would likely benefit from some additional bracing and perhaps stuffing. One could experiment.

My 2 cents




Good luck

btw, those numbers may be off, that was one pass thru with a spell check only

I am guessing that you have the ULF covered?

Multiple CerwinVega.

My 12" started to roll off around 35hz and it hit hard. Shop around for the best price and also consider the CLS-15.

Other options include;

JBL Active powered 18", free shipping, under $1000 each. This would only get you two subs, but PM me, because this is being offered at $300 less, per box and free shipping, less than Parts Express. Absolute steal.

This would be a much more sophisticated product than the Peavy, but you only get 2 instead of 8. Neodymium driver, differential drive, DSP contouring, limiting, (2) 500w amp channels summing in the VC for 1kw total drive. The -3db point is 39hz, specs out @133db peak, so continuous likely around the high 120s, so two of these easily into the 130s continuous, with a peak of 139db

Also, w/the sophisticated motor, and the amp being optimized and right at the drivers terminals, I'd suspect driver control and over-all tightness and linearity would be very good through most of the range.

So, there's another $2k option. Simple, powered, limiter, higher quality, lower output.

Here is the spec sheet.
