Eminence Lab12

Basically high Spl wasn't too important as room sizes here in the UK are modest, and realistically I'm not going to get massive volume levels from a smaller size enclosure. Quality and extension were important however, as was the wife friendly factor of a smaller enclosure !

Well distortion will be high,and SPL will be limited to near 100db with EQing the sealed enclosure.

If one has a choice, it only makes sense to get the highest possible spl in order to get the most from the amp powering a given driver. You can always turn the volume down. If a particular driver is 3 dB louder in one application vs. another, it's the same as having 50% more power.

+3dB is the same as 100% more power.

smallangryboy, I would think that a heavy driver like the Lab12 would cost a fortune in shipping. As you have already called on BK to provide information, why not support them as they are a UK vendor and buy it from them? They also sell a nice range of amp modules, both pure modules and plate amps.

BK are waiting on PCBS for their new range of amps, with EQ capabilities, and also awaiting the first of the new Peerless XXLS drivers. I will be interested to hear what they have to say on the relative merits and performance of these new products.

I've no problems supporting local suppliers, however the cruel irony is that even with shipping and tax it's often cheaper to import items from the US or Canada that are made in Europe. Patriotism can only go so far when you run a business especially when inflated domestic prices and crippling taxes intervene...

Distortion will be high? Please explain.

Any 12" driver can be made to work in a 50L sealed box or smaller! Just use a Linkwitz transform and you can easily make it 1 cu ft and get the Qts and extension you want. As always you give up output to achieve this. It's with vented boxes that the parameters are critical and impact more on what box size you can have. The XLS wants a small box, whereas Shiva and others typically require a large box. Then you have drivers like the AV12 somewhere in the middle.

Personally I find the output of most drivers in a sealed box to be not enough. I heard a Shiva in a 50L sealed box and found it disapointing - not much more than I could already get from my mains already.
