Specification Sheet
Product Reviews
I previously reviewed this speaker and after spending more time with it I want to give it a five star rating- it sounds great- moves a lot of air(efficient) and sounds really good.
I used this speaker for a 5f1 champ build - the speaker has great volume and response- very high quality. It does have a lot of bottom/ bass response so I did need to re-voice the amp a bit to sound correct and not muddy- which is the reason I only gave it 4 Stars. Antique electronic supply is the best place to buy everything and their service is spectacular!
