Default How to kick the speaker building blues?

It’s not my project. I blew an amp doing a xo experiment 3 months ago and I have a long repair time. I think it was a series of events not just the amp that’s got me at a stand still. I have a backup amp. I just can’t seem to right now. Strange because I was getting to the good stuff. Anyone here get thru the speaker building blues? How?

First practice your passive filter networks in a simulator, then when everything looks benign, hook it up. The objective is to have acceptable impedance profile and FR. Amplifier should also have some kind of short circuit protection, at least a fast acting 2A fuse in series with amp output before speaker terminal.

I'm having the blues at the moment, too. The speakers I normally use (Behringer B3030A, modified) aren't doing the magic for me, and if I'm honest, they never really did.

We're in the process of re-modelling the AV equipment in the lounge, and I need to find something better.

It's difficult, though, to know where to begin. Back to full-range drivers? A better studio monitor design? 2-way, 3-way? Subs? Etc etc etc.

I have a few bits here and have tried them as the main stereo, but nothing really sticks...

Tell the Boss you are tired of building speakers and have decided to buy a new BMW motorcycle, then report back

You have two choices.... get on with it or give it away.

A while back I thought if I saw any more saw dust I would spew as I was running on autopilot building. That was about a dozen speakers ago as there were still ideas running though the brain as well as some drivers I wanted to try.

The worse part of any job is starting or restarting.

Stereo subs with JBL LSR 305s can be very satisfying.

Stereo subs ?

How about stereo woofers ?

I find a lack of room penetrating bass under 200hz a deal breaker to me, especially for smaller drivers.
Pick the monitors off the floor, even less bass.
What is rock without a bass guitar? No foundation.

I'm thinking something like the (now gone) diysoundgroup tempest but change the woofer's crossover for dual delta pro 12a in series. Dual 12 for midbass slam, the tweet is closer to ear level, and no floor bounce killing the bass. But i love current passive setup and its horn.

Listen nearfield maybe.
Hang in there, rearrange, or it may be the day.
Our music enjoyment of the system can vary based on your mood, even if you don't feel off.

Norman
