Looking for 2 full range speaker recommendations

ChrisRiggle · 04:22 AM

Hi all,

I started to do a desktop build a while back but had to postpone due to life interrupting. Anyhow I'm back and ready to do a desktop build similar to the link below. I really need a 4 inch shielded full range speaker recommendation for the amps below. Price wise for the Lp-2020a I'd like the speakers to be around 20 to 30. The Qinpu - A-6000 MKI is another amp I'm looking at down the road for and upgrade. I'd also appreciate a 4" speaker recommendation for it with a price range around $80.00 each.

You can take a look at the Mark Audio Alpair 7.3, CHR-70.3, and the Tang Band W4-1320SIF.

Lot of folks have done builds on the forum with these drivers and there should be plenty of review/listening impressions based on their expereinces.

Thanks for your reply. Those speakers have came up on my searches and I have the Tang Band saved as one of my favorites. Do they make shielded versions of these speakers? They will be used on my pc desk and I always have items that aren't magnet friendly on my desktop charging or docking. You know, cell phones, tablets, HDD etc.

The MA Alp 7.3 is magentically shielded IIRC.

Edit: Noticed that you had mentioned "shielded" in the subject line of the first post.

ChrisRiggle · 21st March 2013, 09:58 AM

How do you feel about the Tang Bands W4-1337D? Shielded, full-range, what's not to love? From what I'm reading the MA Alp 7.3 would need a larger inclosure than what I'm going to be building.

ChrisRiggle,

I haven't heard the abovementioned TB model. I've listened to the Alp 7.3 and really liked it. You can get some enclosure ideas here:

Frugal-phile | Box Library / Mark Audio

The P10 Mini Onkens are reasonably sized bookshelf speakers.

jerrymchill · 22nd March 2013, 04:13 AM

Chris, both amps are not the best choice, the Lepai is fun for a short while then you realize how distorted it sounds - it is a cheap build - nothing for serious listening - perhaps for backyard...

The very best champ on the block is the Dayton DTA 100a for mere $80.00 or so. U simply cannot do better than that. They have some quality issues but if get lucky it's the best $80.00 you will ever spend.
4" drivers - TB is a good choice as the sound is natural out of the box, other drivers will take lot of time to tune. But if this is for a desktop I would consider 3" TB drivers as there is simply no contest in resolution and fidelity - the 4" drivers sound already congested if not implemented properly.

I built these computer speaks with Tang Band W4-1320SJ. 4 inch PVC T and end cap. About 3.5 liters tuned to 80 Hz.

It's a neo motor, but it is enclosed with steel. Don't know how shielded it is, but it sounds real good. Near field, about 18 inches from my head.

ChrisRiggle · 22nd March 2013, 07:04 AM

For now I've ordered 3" Tang Band drivers and a Lepai amp. I really wanted to go with Mark Audio but I wasn't able to find a speaker that would work for my application, shielded 3" to 4" that will be great for a small enclosure.

Jerry, Thank you for your post. It lead me to about 3 hours of reading. I really like the look of the DTA100a and the reviews are great. As you point out, I'm a little worried about the reliability. However after reading bout it and class T amps, it lead me to the topping TP30 amp. It's only 15w but has an on-board sound card. For my application, on my computer desktop, I think it'll fit my application best.

jerrymchill · 23rd March 2013, 12:59 AM

Chris, the Topping TP 30 is a good amp - sounds refined with the 3" TB - that will be a great set up. The USB DAC on it is couple of years old but sounds fine.
Definitive upgrade over anything on the plastic black box market. Cheers!
