If you were using an active bass or higher output pickups, then you might find you don't need to have the master as high. On the other hand, if you use a different passive bass, you might find you need to turn it up further. The amplifier just amplifies the signal that it gets. So if it's not an overly powerful signal to start with. You could increase the input gain to clipping. Just use your ears (well, one ear for your IEM & one for your rig).

If it sounds bad, you can always do a bit of reverse engineering & get drivers to suit the cab dimensions & then build another 2x10 cab that suits the spec of your eminence drivers. Then sell one of the cabs at a good price to cover the cost of both builds.

I wasn't suggesting that the idea of porting or working with the cab was a bad idea. I was just doing one of my car analogies. I had one of those Rovers. 3.6 V8 that went like stink.

I think what Bill is saying is that it's like sticking a Ferrari engine in a Rover. The Rover might hold the engine, but you're not gonna get close to it's full potential. Yes you can then modify the Rover, but it's still not gonna go like the Ferrari.

Both (even stacked on top one another) are a damn sight lighter than the valve amp I have.

Seems strange that your map isn't giving you enough volume, but it goes to show that watts don't really give any indication of how loud it can go. I used to play in a really loud band with just a 2x10 Markbass combo & never struggled to be heard (though most of the venues never held much more than 300 people). [quote name='markstuk' timestamp='1487025173' post='3236432'] The newer generation D classes are worth a look at - the ones in the 800w range. I love my thunderfunk 750 which has edged out my rh750.. [/quote] As you probably know, the RH750 isn't able to put out 750 watts.

Indeed. But it can be sooo satisfying to get that awesome sound that you never thought was possible.

You'll find plenty of information in these pages. Another good place to read is Barefaced bass cabs' website. Alex has put a lot of good info on there. Also go to Bill Fitzmaurice (BFM) website. The forums there are a vault of info too.

I used to have a Markbass 2x10 combo. One handed carry. Now I have a non neo EBS 4x10 and a stonking big Radiovox valve amp which has a casing made out of used battleships & weighs the same as a tanker full of dark matter.

[quote name='Powertripper' timestamp='1486945574' post='3235833'] I've since totally changed and elaborated on my problem but thank you for responding to the original post, much appreciated. [/quote] Oddly enough, I was editing mine at the same time. The answer is still the same as my original edit. Use your cabs with the amp. Use your ears. Bill the fandango for the repairs & don't let anyone use your rig again unless you're there & have some trust in them.

Yes. Forget watts. Check ohms if using more than 1 cab & use your ears. Your watts theory is incorrect. If your cab is 8 ohm & the amp's min load is 4 ohm, then your amp will put about 350 watts out at most. You're more likely to be averaging about 100 from the amp.

Well underrated bassist. She's where I get a lot of inspiration from. Her synth basslines are superb too!

I used to have the 102P combo, which was basically a 102 STD with an LMII popped into it. It never lacked lows or decibels. I'd opt for the 8 ohm if you can, as it would allow you to add a 2nd if you ever felt you needed to. 4 ohm doesn't give much of an increase in decibels & only puts a bit more wear on your amp's components.

Why do you want a 4x10?

I was using the "Big Stack" preset with a wee twiddle of the settings tonight to play along with some tunes. Try popping an EQ on the channel & tidy the sound up. Maybe add a touch of subtle reverb too.

I had a TE 4x10 combo. Was unimpressed. Replaced rapidly with a Markbass 2x10 combo which blew the TE away in every respect (weight, sound & decibels). My current rig however is a 4x10 with a valve amp & weighs more than my car!

Not long after seeing the pic, I saw the trailer for Stranger Things 2 & it's about everything getting turned upside down. So with that, I thought "80s sci-fi", so I give you Torino... https://soundcloud.com/gxmix/torino Enjoy!

Seriously, I need to get myself one. I've got the money, but there's a few things calling out for my hard earned (including the Mrs).

+1 to try before you buy. I tried 4 fretless Jazz basses out, all Fender. Out of the ones I tried, the Squier was the best value & with a better set of strings, would be a better bass than the MIM Fender. Wasn't as good as the USA one, but it is almost £1k cheaper.

We're all assuming that you play in a rock/indie/guitarist band. If you're a different genre, such as DnB or Jazz, you might want to keep all those lovely lows & mess about with the mids & low mids instead.

You could get a Squier Jazz & spend the extra on better pick ups, electrics & strings.

Isolation risers such as gramma pads or drum riser foam are advertised as being able to reduce boom (I bought a length of drum riser foam & chopped it in 1/2), but sitting the cab on a beer crate or a couple of bricks usually has the same effect. Like Lozz says, the best way to get rid of boom is to turn the lows down a bit.

Wrap it in vinyl.

PPAP - Pure cheese & makes my niece smile! Dancing Queen is the one song I can truly say that I detest. Abba were great musically, but that song does everything in the most irritating way.
