One question, how does the Eminence LAB15 15" compare to the 15” HO? Seems like PSA is using these drivers.

In what way, that is an open ended question.



Lab 15: More expensive, normalized motor strength ( Bl^2/Re ) of 145.49. 11.8 mm xmax. Copper wire on aluminum former, 3" diameter coil.



RSS 390HF-4: Cheaper, normalized motor strength of 75. 14 mm xmax on the datasheet. Copper wire on aluminum former, 2.5" diameter coil.



Not quite double the motor strength on the Lab 15 compared to the RSS 390HF-4. Moving mass difference is 2 grams between the two. The RSS 390HF-4 has twice the compliance of the Lab 15. ( 0.22 mm/N for the RSS 390HF-4 vs 0.11 mm/N of the Lab 15 )

Just Looking to build two enclosures similar to the psa S151 or V1510 and would like to know which of this drivers fit better, UM , HO or HF.

The larger of the two, the V1510 is 24 x 25 x 17" external, if 3/4" thick material, about 4.74 cubic feet minus bracing, port displacement and driver displacement.



Do you have a specific size constraint?

WAF , those are about the right size, I will have to check if I can fit something a little bigger.




Apologize for asking on your thread Op.

Please find a different thread to troll.
To be fair, Both gentlemaniac and Notnyt were involved in this back and forth. Instead of singling out gentlemaniac, they both should have been asked to cut it out. Just saying.

Thank you, and yes I agree, we should've both probably not jumped on this guys thread going backwards and forwards about it. Apologies all round
