Amps come in 2 different versions - tubes vs SS (solid state). Think we can forget about tube amps for you Usually best to match the speaker (watts) rating with the amp output - but even a 30W amp on a 100W speaker is OK. Do not overpower the speakers as you will FRY them Newer amps are usually rated at their published watts level; vintage amps normally have a higher actual watts level than their published rating. Most residential Klipsch speakers can be powered with amps 20-100W. Pro speakers are usually 300W and up. They require pro amps of 300W and up. More power usually gives you a tighter bass response and faster (tighter) high/low transients. Speaker boxes are usually 2 or 3-way, meaning they have internal electronics (i.e crossovers) to split the incoming signal to 2 (or 3) internal speakers (bass/mid/high) which require different frequency ranges. A 2-way speaker may have a low frequency range from 20-800Hz and a high range of 800-20kHz. Good hi-fi speakers, such as Klipsch, have balanced the box dimensions/ports with the characteristics of the low/mid/high speakers and corresponding crossovers. Hope this helps Cheers, Emile

Haha; never even heard of deep house, garage, jungle, footwork and dib. Seriously dislike hip hop / funk. OK; you play music at 75-80dB - i.e. louder than an alarm clock and less than a vacuum cleaner. (I play mine at about 100dB.) In your range any Klipsch speaker will deliver even with a low, low wattage amp. And yes; Klipsch speakers look much better than rat-fur JBL's (Just wanted to check your intended purpose.) The Polk T15 speakers you have just are not good enough for DJ'ng or music "listening." Background music only or on a desk. They just do not have enough range (nor sensitivity) to deliver the goods. To me, it sounds like you are after the Klipsch "HORN" sound. Suggest you go to Best Buy to check out "that sound," as not everyone likes it - it is more "direct." (And ONLY listen to the speakers; NOT to the sales person as he/she will try to sell you something else.) After that it comes down to how much you want to spend So; $500-$700 should get you a set of used Heresy 1's plus a vintage amp and it will be "fine," meaning MUCH better than your Polk speakers. (or, you could even do KG4's, KG4.2's or KG4.5's.) $700-$1000 will get you a set of used Forte 1's with a used amp ... a bit better. Most people on this forum love Forte's but I am not one of them $800-$1400 gives you CF3/4's, but now you will need a "better" amp. $1000-$2000 will give you LaScalas, but you will have to add a subwoofer - meaning 2 amplifiers, or 1 for the speakers and 1 build into the sub. $1000-$3000 will give you pro Klipsch speakers, but you will need a serious amp and they only come with black textured paint Haha; not wanted for your living room. Therefore (especially at your sound level), I suggest you start with a pair of Heresies. If not sufficient, you can easily resell them and move up to the "next level." Cheers, Emile

Priced them last year ... they were about $1400 each (or ouch) FYI, bought some K-510's from Klipsch about a year ago for less than $20 each. And new K-691's were about $650. So; quite a premium for 402's

JBL example ... https://tampa.craigslist.org/pnl/msg/d/saint-petersburg-jbl-jrx215-speakers/7383052506.html ... haha; $200 for a pair 15/7372533280.html or $300/pair ... https://tampa.craigslist.org/psc/msg/d/new-port-richey-jbl-jrx-225-double- Or even better ... https://orlando.craigslist.org/msg/d/debary-jbl-professional-srx-4732/7389317792.html ... but $495 each Add a Crown amp and you are done

@jubilee333; @Dave1291mentioned your inquiry to me. I am pretty close to you and can possibly help. (At least I can keep my eyes open for "your" speakers.) Have Heresies, Cornwall's, CF3's and Pro KPT-904's at home. Couple of questions ... for DJ'ng, what type of music do you play, how loud and even more important, what size/weight speakers can you handle. Some here have mentioned Pro speakers and I quite agree (just not easy to transport "large" pro speakers). Also note that JBL makes great pro horn speakers also - and they can often be found locally at pretty good prices; haha, cheaper than Heresies. (JBL usually is found in "rat-fur" cabinets.) Next, what will you power them with? Pro speakers will (usually) need pro amps to get the best out of them. Heresies, etc can be driven with low wattage amps.Also, planning on "plug and play" speakers or do you want to use dsp (digital signal processing)? Cheers, Emile

Tom; absolutely AWESOME ... and a GREAT price The 402's with the JBL 2445's by themselves are worth at least $2K. And; love what you did with the screens GLWS! (Sorry; just too far away from me )

Racer, thanks. Have a set of JBL 2385 (think the are the same as your 2380's but with a narrower angle) with 2" JBL 2446H drivers to experiment with. And, have K-510's with 2" drivers and yes; very pleased with 2" exit drivers But ... wanted to go "bigger (horn-wise)" but cannot fit K-402's in my setup. So; was glad @Marvel mentioned the JBL 2374 horn. But, now searching for 1-1/2" drivers as I'm pretty sure one cannot use 2" drivers on these horns

Haha; looked for that one also

Marvel, thanks Had been looking for quite a while for a "smaller" K-402 (about 4 inches to big to fit in my setup). At 30x15x15" the JBL 2374 should fit. Unfortunately, I just bought some 2" exit JBL 2446H drivers ... and recall you CAN NOT use 2" drivers on a 1-1/2" horn Also looked for @Westcoastdrums's JBL 2432H's, but they are impossible to find. Any good substitutions? Thanks, Emile

Yes, no problem. Driver is "only" supported by the 510 horn ... does NOT rest on box panel

Yes; back is open. Just made them with 1x10 pine. No horn bracket; 510's are screwed in. Wired directly (haha; NO back )

Yes; aesthetics only

Thanks, but I have no dot(s)

Clicking a thread link used to take one to the last post visited. Now it goes to Page 1, post one. Thought it might be "old" history deleted, but same happens when visiting the same new posts. Thanks!

@Shiva Thanks Temporary set up as PC to DAC to Yamaha CR-620 to Cornwalls (my "rear" setup). Played a couple of saved CD files as well as a FLAC file downloaded from HDtracks.com. Haha; do not hear any difference ... guess I need some wine first

OK; finally got a DAC Lavaudio DS600. Don't hear much of a difference though

@jimjimbo

Thanks, but if I had to do it again I'd make it the same width as the 904's

Old, old pic but shows the 904's grill and enclosed 510's

Did them myself ... very easy job Used 1/4 inch plywood (MDF is better since it does not warp) and used Crites black speaker grill cloth. Fastened with velcro.

Just got a pair of those and think they are awesome! But ... don't forget, they weigh about 32 lbs each

The KPT-904's are absolutely the best speakers I have ever had. Put a grill on mine (and enclosed the 510 horns - passed the wife test Someone get these! Pretty good price. GLWS

One more try OK; reran measurement again ... much closer now, but note I did NOT "close" REW. See pics.

OK; reran measurements keeping PC plugged in (1st pic; psycho'd). Averaged them and ran REW to find filters. Input them into my Xilica (4 filters) and results are in pic 2. No clue why I am getting 130db's in the lower freqs, certainly does NOT sound that loud Haha; will try another measurement AFTER my laptop was disconnected. Per your recommendations, purchased a DAC. Was going to get a Topping E30, but found a Lavaudio DS600 which has bluetooth ... should be here Saturday and I'll try again Cheers, Emile
