Re: LMS-5400 / RL-p18" buy-in

All the drivers came with rubber gaskets but the gaskets for the PRs were somewhat worse than the LMS-5400 gasket so I decided to use proper weather stripping with the PRs. I didn't have any problems...

Oh but wait. Good performance on objective measurements doesn't mean anything because they can not tell anything how the subwoofer sounds and feels subjectively. It can sound absolute even...

You don't have to worry any more. The testing is already done and both drivers are still live and kicking. And they did DELIVER. :)

It was a 110 dB sweep.

2nd order BW at 16 Hz.


Yes I did but I will use the stock fans during the measurements just in case.

Re: LMS-5400 / RL-p18" buy-in

I don't think going lower than 15-16 Hz is a good idea. That means one has to use more than 2000 grams of additional weight per each PR... :no:

Re: LMS-5400 / RL-p18" buy-in

I tested the tuning frequency with the ten weights (+nut) that came with the PRs: ~18.9 Hz. So I will need to add some weight.

Does ~16 Hz sound good to you all?

Re: teaser

I don't like T-nuts when it comes to real wood like BB. Traditional screws work better.


How come?

Re: LMS-5400 / RL-p18" buy-in

Both. Now they just reduce resistance but if single Crown CE 4000 isn't enough (remember we have 230V here so ~3600W), I can try two of them (one per each VC). Though that won't be very optimal load...

Yes, that is 15 ply BB. The cutouts are pretty good considering how little time I had. I mean two large enclosures in a less than a week... :dizzy:

So are you saying that neither the AA Tumult nor the CSS SDX15 represent the XBL^2 properly? :scratch:

If yes, may I enquire which driver does then?
