The Sunfire 10" sounds like an excellent choice, especialkly as I take it you are not a Sunfire dealer. Coulkd you tell me a little about who makes Sunfore and where, and what it is about their subwoofer that gives them such an edge? Many thanks...your reply was most helpful. Mckim
Actually, I AM a Sunfire dealer.... DO NOT WORRY, I'm not trying to sell you anything. I think that the fact that I'm a dealer works to your (and sometimes other forum members) benefit: I only comment on my experiences working with different products & their applications. The name of my company is not on this site anywhere nor do I mention it because I enjoy & need the anonymity of the web to leave me free truly help people without possible repercussions from manufacturers. I assure you that Sunfire does not pay me, nor do they give me ANYTHING for posting in forums. They don’t even know that I do it. No company does. I'm not here trying to sway you to buy something as it doesn't personally benefit me in anyway. This is still a hobby for me and I enjoy using my experience to possibly help others where I can. I just saw your post & since I run into this subwoofer problem all the time, figured I could offer some suggestions.
Also, the HRS-12 (Sunfire's 12" HRS model) is 13.5" x 13.5" x 13.5" & will meet your requirement of less than 14". However, I did not mention it because it comes in possibly too far above your budget with an MSRP of $900.
About Sunfire:
www.sunfire.com . They were based out of Washington State but just recently were relocated to Kentucky. Bob Carver (Google him) designs their products. Recently they were purchased by another company called Nortek under the Elan brand subsidiary. Nortek also owns several other brands of audio equipment: Sunfire, Niles, Xantech, HomeLogic, Speakercraft, and many many more. Look here:
http://www.nortek-inc.com/companys.htm , particularly under the "Linear LLC" section.
As far as what gives them the "edge" you'll have to check that out yourself. Bob Carver designed something called a "High Back - emf" woofer and it works extremely well. Here is a link to the HRS page on Sunfire's website:
http://sunfire.com/HRS.htm . The rest of the work is up to you. I know Audioholics did a review of the HRS-12 12" subwoofer. I suggest you check that out too if you'd like to learn more.
Happy hunting for your sub!
