irishboym4 Posted January 27, 2010 Share Posted January 27, 2010 I have a pair of KLF-30 mains driven by two adcom GFA-555 amplifiers. its alot of power and they can play very loud. whats a good sub that can keep up with these? Quote Link to comment Share on other sites More sharing options...
o0O Bill O0o Posted January 27, 2010 Share Posted January 27, 2010 Well, I am on a Pro sub kick, AND you already have big speakers what's one or two more? http://www.jblproservice.com/pdf/Theatre%20Series/4645C.pdf http://www.jblpro.com/pub/cinema/4645c.pdf Also go to Cinema section on the Klipsch Product page Both requires you to get your own amp, EQ, and nescesary cabling. However, you will get clean, high-output bass. Drawback is they're large. if you're staying consumer, go loyal, get the THX subs (Pair) and the AMP. The only drawback is it expensive, and doesn't have as much output as pro-audio solutions. Of course there is the variety of internet direct retailers that offer big bass in medium sized boxes for well under 2K USD. Quote Link to comment Share on other sites More sharing options...
superedge88 Posted January 27, 2010 Share Posted January 27, 2010 I chose to go with the Tuba HT subwoofer to match up with my KLF-30's. Sounds AWESOME. See link below. http://community.klipsch.com/forums/t/128331.aspx Quote Link to comment Share on other sites More sharing options...
irishboym4 Posted January 27, 2010 Author Share Posted January 27, 2010 i suppose i forgot to mention that this needs to be relatively cheap. i have a old Phase Linear 200 series 2 amp that i can bridge to run the subs. i like the pro jbl stuff. and i like the numbers on it. the tube sub.... the link didnt work...

superedge88 Posted January 27, 2010 Share Posted January 27, 2010 Sorry about the link, it works but you have to cut and paste it. I haven't figured out how to actually put links into posts. The Tuba HT would cost you around $300 since you already have an amplifier. This sub only needs about a 200 watt amplifier to get to insane volume levels.

irishboym4 Posted January 27, 2010 Author Share Posted January 27, 2010 i did copy and paste it the first time and it didnt work. i tried it again and now it does. who knows but ill check out that sub. what kind of spl does it give? and how much power can it take? i have a 300w amp that i built that can drive a 4 ohm speaker with ease...

irishboym4 Posted January 27, 2010 Author Share Posted January 27, 2010 do you have plans for that beast? i want to build one now Quote Link to comment Share on other sites More sharing options...
superedge88 Posted January 27, 2010 Share Posted January 27, 2010 Here is a link to the plans website which is $15 http://billfitzmaurice.net/THT.html If you go to AVSforum you can search through their DIY forum and see about 10 different build threads that are very informative. Here is a link to my build thread. There are pics throughout the build thread. http://www.avsforum.com/avs-vb/showthread.php?t=1196669 If you do a search on AVSforum you can also use THT (short for Tuba Home Theater which is the name of this subwoofer) This sub is a beast! You can find graphs and all kinds of data on the avsforum regarding the abilities of this awesome subwoofer. Your 300 watt amp will EASILY push this sub to levels of nirvana.

o0O Bill O0o Posted January 28, 2010 Share Posted January 28, 2010 DIY is rewarding, but ensure you have the capability. Tools, time, and more time. When I was in High School and College I built many subs and speakers. Now, I lack DIY time, and I am willing to sacrifice some budget for what JBL or Klipsch make. but not too strapped for time blow the budget on a well designed and integrated sub from a commercial design... such as tempting designs as JL Audio's F113. So my recommendation is based on time and money. More time = DIY More Money = Complete Design. The factor I can't control is education, and to get on my soap-box, that's you're responsiblity, stepping off soap box.. Hope this helped and not sounded too preachy.

russ69 Posted January 28, 2010 Share Posted January 28, 2010 Check out Hsu Research, they have very good subs and the pricing is fair. The Hsu subs use light weight cones and are a good match for high efficiency and panel type speakers. Thanx, Russ Quote Link to comment Share on other sites More sharing options...
o0O Bill O0o Posted January 28, 2010 Share Posted January 28, 2010 HSU Subwoofers are great, my annecdote: I used their automotive subwoofer in my car back in high school and college. I recommend 2 or more subs, if you get any subwoofer. Look up Floyd Toole and subwoofers on JBL or Harman internationals website for justification to why. My opinion ~$1000 is the line in the sand for price to performance ratio in anything to do with audio, speakers (ea), amps, or subwoofers. also did some more research. 2X (JBL 4645C ~$1000) + 2X (Crown XTi Power amp ~$500) + Velodyne SMS-1 ~$400 + $50 cables= $3450 (!) -But > 120 dB output 120HZ on down, which match the KLF-30 capabilities ( read hometheaterhifi's review of the Klipsch KLF-30) Quote Link to comment Share on other sites More sharing options...
superedge88 Posted January 29, 2010 Share Posted January 29, 2010 The THT can do 120 dB. See link. The wider you make the sub, the more flat the response becomes. Most guys don't have to have a huge amount of EQ to get some pretty flat response. This subwoofer seems to be an exception to the $1000 line in the sand according to the opinions of most, at least most guys on the AVS DIY forum at least. This sub can actually compete with the Danley DTS-10, but for a fraction of the price. Quote Link to comment Share on other sites More sharing options...
o0O Bill O0o Posted January 29, 2010 Share Posted January 29, 2010 you mean the more volume you make the sub the flatter the response? Looks interesting, but you have to account for the skill level of the builder, time it take to build, tools on hand, and equipment to tune it.

superedge88 Posted January 29, 2010 Share Posted January 29, 2010 Yes, the plans show that you can make it as small as 36 X 36 X 18 all the way up to a complete cube. The plans show a cut sheet lay out for a 24 inch wide version. You do have to account for the skill of the builder, but as you read through the 10+ build threads on AVS forum you soon realize that this is NOT a difficult sub to build (though I was frightened since I was one of the first build threads on AVS forum so I had less of an idea of exactly how difficult this build would be) I for one am pretty scared of woodworking, not very good at it at all. But after building this sub with my buddy Joe I would definitely tackle building this sub by my self with a good table saw, jig saw, clamps, saw horses, and brad nailer. As far as equipment to tune it, I assume that you mean EQ? I have only used the Audyssey Multi EQ that is part of my receiver and am pleasantly impressed with the audible difference it made and right now have no further need to do more EQ balancing. Hope I didn't derail this thread too far for the OP, my apologies. If anyone has more questions about the THT please go to the powered subwoofer forum and see my thread about my Tuba HT subwoofer- What's been keeping me busy for quite a while (project pics) Quote Link to comment Share on other sites More sharing options...
