When I was down at RCF this summer and asked about the 9006 the guy told me that the drivers had double "something". I didn't understand what he said. Double windings, coils, double what.. That sub sounds amazing at least.

Double voice coils, maybe.
Could also just be double-layer - inside/outside winding is pretty common.

RCF makes a number of drivers with dual wound inside/outside  voice coils, dual "Forced Hyperventing", and dual spiders.

A trio of doubles...

First off, both subs sound amazing.  One will easily put out what two of my srx828 will.

The 9006 was my favorite.  It had incredible punch and the clarity was some of the best I've heard in a sub.  I was very impressed.

This is the third time I read of “One will put out what two of my subs will”. What makes this possible? So with this statement, Will a single 9004 put out what one srx828p will?

Has anyone heard the 9006 and Bassboss SSP218?  Both look to be excellent, self-powered, dual 18" front loaded subs above the typical MI grade (QSC/JBL/EV/EAW RSX/etc) level. 

Past that - how do the above compare to Meyer?  Is Meyer really 3x better?

Our 20+ year old Meyer 650 R2 on paper should be wimps but 6 of them outrun 6 STX828, 12 easily handle outdoor crowds of 5000+ with rock/blues.

I should measure them sometime.

Luis,

Without direct measurement of both, hard to answer the question.

That said, the SRX828 uses 2242H drivers which have an Xmax (linear excursion) of only 7.87 mm, not a lot for a 21st century subwoofer.
There are many current drivers with double or more that Xmax, doubling Xmax (given the power to achieve it) results in 6 dB more output, the equivalent of doubling drivers and power.

Not to nitpick, but the SRX828s actually uses 2279H drivers. I can't find official specs online, but I've read that other than the 2279's ceramic magnet structure, they are pretty similar to the 2268H and share the same recone kit.

Michael,

The 2268H is also around 8mm Xmax.

I was just going from the JBL SRX828s spec sheet, did they change from the 2242H?

Do you have the original drivers in them?

Comparing Danley TH118 (I think I want to upgrade to these), STX828S (the JBL'ss I have 6 of them, our B system) and Meyer 650-R2 (we have 12 of these, our A system)

I found this thread interesting, can I really replace my workhorse Meyer's 2:1.  This is what I came up with (specs on the bottom). 


The amazing thing,  The Danley's are about 4 db continuous and 6db apart from the Meyer.


The JBL's don't go as low but are really inefficient, taking shitloads of power to do the same thing..  99db efficient, again about 6db so they need at least 3000 watts to do what the Meyers do on with a 1000.


The Danley's would replace the Meyer's 2:1 but need three times as much power. 


The JBL's should keep up with the Meyer's but they don't and they are nowhere near as musical.


The Meyer's are paid for and despite their age nobody would turn them down.

The Meyer's and the Danley TH118XL's are about an inch apart in dimensions.


Interesting stuff.
