thunerfunk 550b and 2 aguilar sl112s... willit work??

Hi guys

im looking to build my own bass rig. im an out and out funk and soul player. i want something light easy to move and punchy..
im thinking of the thunderfunk 550b (saw a second hand one for 660 GBP) and starting that with an aguilar sl112, later adding a second cab. both have good individual reviews.

i doubt anyone has paired either of these as one is a rare head and the other is a relatively new cab. if for some unexplainable reason someone has could they tell me what it sounded like? or some combination that was close?

secondly im not that sure about all the tech specs?

the cabs run at 250watts at 4ohms and the head runs at 550watts into 8ohms and 300watts into 8ohms...... so what exactly does this mean?

through one cab would i get 300watts into 250?
and through two still 300 or 550?

any advice would be much appreciated

Just about my favorite rig tone ever was a Thunderfunk 550 into an Aggie GS112.

First, the Thunderfunk550 is 4ohm minimum, so you can either use one 4ohm 112 or two 8ohm 112's with it. I'm pretty sure the Aguilar neo 112's are 8ohm, as are most production cabs. So, not problem there. The wattage rating of the cabs is not particularly useful, but a cab with 250 watt rating can comfortably operate within a pretty wide range around that.

One of my favorite sounding rigs of all time is two DB112's and the Thunderfunk550b. I don't think we had a GTG where that particular rig wasn't among the most favored.... warm and punchy and smooth and organic... wonderful.

Since many have posted that the little Aguilar Neo's sit kind of between the DB and GS cabs, that should sound great as long as you don't want HUGE low end, or super modern sizzle in your tone.

If the cabs are 4 ohms, running two of them will result in a combined impedance of 2 ohms. The TF 550A that I have is specifically not recommended for use with a 2 ohm load; I suspect the 550B has the same warning. To run two cabs, you'll either need to get 8 ohm cabs or get a head that is safe down to 2 ohms, such as the new TF 800.

I can't reply in reference to the SL, but I love my rig!

Any combination I use gets me a great sound. It makes me want to play!

Super portable, versatile, plus the whole rig is built like a tank.

Inevitably, when a Thunderfunk/Aguilar thread gets started, eventually someone will comment about the GS series being mid-scooped. While they are, especially when compared to a Berg or similar cab, I have no problem shaping my tone for whatever venue I am playing in. In some instances, I will be playing with the EQ flat. In my eyes that means I have a tons of options left, in the event something needs tweaking!

I also like the gs aguilars, haven't heard the sl's but bassed on my experience with my 550 and the gs112s and the reputation of aguilar in general it should be a killer rig for most situations. no fears

thanks guys some great advice... however i have got some stuff wrong i wrote that
"the cabs run at 250watts at 4ohms and the head runs at 550watts into 8ohms and 300watts into 8ohm"

which was wrong
the cabs actually run at 250watts at 8ohms and the head runs at 550watts into 4ohms and 300watts into 8ohm

so how would this work with one and two cabs?

PS> dmrogers that rig looks amazing!

also why do you have two heads?
how does that work?

I have the SL112's. One is great, but 2 are awesome. I use the Epi 501 or 902 amps.

Concerning the head/cabinet combination, it is really very simple: my 550B has a minimum impedance of 4 ohms

(Actually Dave states that you can run the 750 at a 2 ohm load, but I don't do it. So for simplicity, let's just the 550 as an example). This means your minimum total impedance should equal 4 ohms or better.

So, with the 550B head (or any head with a 4 ohm minimum load) you could run the following setups:

1. One eight ohm cabinet.
2. Two eight ohm cabinets, for a total of 4 ohms.
3. One 4 ohm cabinet.

(And if you would like, you could actually match up cabinets for a total impedance of 2 ohms for the TFB750, as per Dave Funks web site. We could also get into cabs with a difference impedance such as 16 ohm, but you can read the FAQ for more info)

In matching heads and cabs, you want to make sure you don't exceed the minimum impedance of the head.
This thread explains the whole impedance matching deal quite nicely.

I have two heads for convenience and a backup. On my last regular gig, I had the 750 head and two GS112's setup at the church I played regularly. The 550 and one GS112 was used at home for practice. The 550 would travel with me to other gigs as a backup head, just in case......
I haven't played a gig in recent years where I needed more speakers than 2 GS112's, they work quite nicely. However, if I wanted/needed to, I could split my bass signal and use both heads, with one head driving one speaker and the other head driving two speakers.

I hope this information helps.
