Upgrading woofers in a/d/s L2030, need help

Hi folks, I have a pair of a/d/s L2030 speakers which have two 14" woofers in sealed enclosures. I am unaware of how many cu ft each driver is exposed to.
The drivers have a hexagonal shape.

I have owned a pair of infinity irs beta's in the past and loved the bass response. I am driving a bi-amp setup with one adcom 555 for the woofers both sides.

I am not getting enough bass out of the speakers, but I love the mids and highs, so I was thinking of upgrading the drivers.

I would create a plate out of metal to match the hexagonal shape of the original drivers, and then cut out an appropriate mounting circle.
I could get away with 13" or more standard 12" drivers.

As tacky as it seems, I may select a car audio driver that works well with sealed enclosures of various sizes. I had one of the 14" drivers replaced, and when it was out I noticed how puny the magnet was. And how today's voice coil structures and magnets seem infinitly larger.

Does anyone have any suggestions?

Thanks
Andrew

Andrew et al:
I have a pair of L1530s and had a similiar problem with lack of bass but it turned out the problem was upstream. My digital source was the culprit. Believe it or not it was a very old fuse in my digital front end. I replaced it with a hi-fi tuning silver star fuse. After this change the speaker's bass felt like an assault. Huge improvement. I also rewired the speakers with Analysis Plus clear oval which improved the overall sound as well.

Do you realize how old this thread is?

I'm pretty sure Michael Kelly of Aerial Acoustics built the 2030 speakers. I know he was one of the main designers of ADS speakers in the 80s.

Irvrobinson, do you go thru threads to make these comments? Do you own ADS speakers? I don't see your name anywhere in this thread outside of this entry. Aren't you going to correct Doug99 as well? I suppose you have Fisher speakers too.

Sounds like an interesting speaker w/ those 14" woofers.
Yes, a/d/s was great at providing outstanding mids & highs.
The company also made great car audio speakers as well.
Those, too, were not known for their bass properties.

I would never alter the original design- rare and valuable speakers indeed.
