What did I do.....

[aende]

So, after a stint of 2 weeks Paternity leave, I decided to remove the horns and crossovers from my Peavey TX 210 cabs.....As I have always had the horns on low to zero, it seemed stupid to keep them in the cab.

I had 2 aluminium plates made up: 1 for the back plate/jack plate and 1 for the baffle where the horn was cut through.

All I can say is; Result!

5kg lighter per cab and they sound pretty solid and fat.

The cabs are loaded with Eminence Beta drivers, in fact I removed a set of Eminence Alpha drivers which I will put up for sale on the site.

What sparked this annihilation? Well, I bought a 1000w Ashdown Little Giant.....and was going to update the Eminence Alpha drivers to cope anyway as they are 150watts each.

OBBM is kindly providing some cables to make the rig happen.

On another note - I am running; 500w per 210 cab....anyone see any issues with this?

No problems as long as:

1. Each speaker cone is rated 250 watts or more - and just having looked it seems the Eminence Beta is.
2. Or more importantly, you let your ears tell you if there`s an issue.

That said, I can`t imagine anyone needing to push a 1000 watt amp to its limits, so as long as you follow number 2, there shouldn`t be a problem.

Thanks Lozz,

TBH, I was more worried about rattling the cab to pieces if I wind up the volume!

I think the speakers will be fine, but the shell may disintegrate!

If the cab is tacky enough to break up from vibration, it will be compromising the sound long before that point.

[/quote]From the standpoint of not cooking the voice coils, true. But with only 3mm xmax they reach their mechanical limit in the lows at about 50 watts each, so any hint of farting out should be well heeded.

Yep, use ears to monitor wisely is the best way.

I don't think I'd be putting a lot of volume into the cab myself so would take the power handling 'figure; with a pinch of salt.

Go carefully

Hi Bill,

Maybe you can aid me here; there are 2 params I was looking at when choosing the driver:

xlim
xmax

On the Beta;

Maximum Linear Excursion (Xmax) 3mm
Mechanical Limit (Xlim) 8.6mm

On A specific High end bass driver; Eminence Legend B102:

Maximum Linear Excursion (Xmax) 3mm
Mechanical Limit (Xlim) 8mm

What I thought this meant was that the beta had more mechanical movement before excursion........i.e. 8.6 mm of mechanical movement versus 8mm mechanical movement in the b102. The 3mm was the excursion where the driver struggles, but will tolerate before damage occurs beyond the 8mm.

Please correct me if I have this wrong; could you advise on a 'perfect' bass guitar driver and what you would expect to see as xmax and xlim?
