If you’re a Bass player, your ideal set up should be a combination of   15” & 10” speakers.

Over the years I’ve used various equipment, ranging from Marshall 4x12 stacks, 4x10 cabinets &  even  2x18 cabinets.

The best set up I’ve found for my regular gigs is a good bass amp around 300-400W, 1x15” Cabinet with a 2x10” Cabinet.

With this set up, you’ve got enough power from the amp to get a decent volume with good quality tones, & the two cabinets cover any frequency range you’ll ever hope to re-produce at a gig.

 


I found this on the Web & built it to complement my 1 x 15” Cabinet.

 

2 X 10" MIDRANGE AND HIGH FREQUENCY CABINET (UP TO 500W POWER)

 

 

Here’s some information before you start:

Let’s assume you’re a Bass Player using a 1x15cabinet, & want to add the 2x10 cabinet.

Forget the Tweeter & Crossover.  I’ve done a lot of research on this.

Tweeters are more bother that they’re worth.

They’re too easy to blow, & they pick up all sorts of noise/hisses/pops. I’ve now dumped my Tweeters.

 

Crossovers are a personal preference.

You can actually work out a crossover  frequency  which will bias your sound  towards the 2x10’s, or the 1x15.

This will take a bit of experimentation & calculation, but if you have the inclination, & want a unique sound, go for it!

 

For what it’s worth, my advice is just build the 2x10 cabinet & forget all about Tweeters & crossovers.

Provided you get the Impedance & Power Rating correct, you’ll be ok.

You now have two cabinets. Cabinet #1 should have the same Total Impedance as Cabinet #2.

 


Construction:

The Cabinet dimensions are minimum sizes. You can “tailor” the dimensions to match the width of your existing cabinet.

HOWEVER YOU MUST ACHIEVE THE SPEC FOR THE TOTAL VOLUME! (8800 cubic inches).

Bear in mind that you’re building a “tuned” cabinet.

Cosmetically it’s up to you how the cabinet looks.

 I covered mine with the same (almost) velour as my existing cabinet & added 2 x 10” speaker grilles.

 Looks just like a matching set.
